Building in Australia has never been straightforward. Between rising material costs, extended council approval timelines, and a construction industry still grappling with capacity constraints, getting a project from plan to completion demands more than just a good builder and an approved DA. It demands the right finance structure — one that understands the unique rhythm of construction and releases capital when and where it is needed.
Construction finance is the specialised lending product designed precisely for this purpose. Unlike a standard property loan that settles in full on day one, construction finance is staged, progressive, and purpose-built to fund the physical act of building. Whether you are constructing a single dwelling, a townhouse development, a commercial fitout, or a multi-lot subdivision, the principles are the same: funds are drawn down in tranches as work is completed, verified, and certified.
Yet despite its critical role in Australia's $150 billion construction sector, construction finance remains one of the least understood lending products among borrowers. The terminology is dense. The process involves multiple parties. And the gap between what banks will fund and what projects actually require has widened significantly in recent years — creating an expanding role for private lenders who can move faster and assess feasibility with greater nuance.
This guide covers everything you need to know about construction finance in Australia in 2026 — from the mechanics of progress draws to the documentation you will need, and from the real costs involved to the scenarios where a private lender delivers a better outcome than a bank.
What Is Construction Finance?
Construction finance is a secured lending facility specifically designed to fund the building, renovation, or civil construction of real property. It is fundamentally different from a standard property loan in both structure and execution, and understanding those differences is essential before you begin the application process.
With a standard property loan, the lender disburses the entire loan amount at settlement. The borrower receives the funds, the vendor receives payment, and the mortgage is registered. The transaction is complete in a single step. Construction finance, by contrast, operates as a staged facility. The total approved amount is committed upfront, but the funds are released incrementally as the construction project progresses through defined milestones.
This staged approach serves multiple purposes. For the lender, it ensures that capital is only deployed against completed work — reducing the risk that funds are advanced for construction that never materialises. For the borrower, it means interest is only charged on the portion of the facility that has been drawn, rather than the full loan amount from day one. And for the broader project, it creates a natural cadence of independent verification that helps catch issues before they become costly problems.
The Core PrincipleConstruction finance is released in stages as building milestones are completed and independently verified. You only pay interest on funds that have actually been drawn down — not the total facility amount.
The lender's security position in construction finance is also unique. At the beginning of a project, the security may consist of little more than a block of land and a set of approved plans. As construction progresses and value is added, the security improves with each completed stage. By the time the project reaches practical completion, the security has transformed from raw land into a finished building worth significantly more than the loan balance. This value-accretion dynamic is central to how lenders assess construction finance risk.
Construction finance can be provided as a standalone facility (where the borrower already owns the land outright) or as a combined land-and-construction loan (where the lender funds both the land acquisition and the subsequent build). The structure depends on the borrower's circumstances, the project type, and the lender's appetite for the specific deal.
In Australia, construction finance is offered by major banks, second-tier lenders, credit unions, and private lenders. Each category brings different strengths: banks offer the lowest rates but the slowest approvals and most rigid criteria; private lenders offer speed and flexibility at a higher cost. Choosing the right source depends entirely on your project, your timeline, and your borrower profile.
How Construction Finance Works
The mechanics of construction finance follow a structured, multi-step process that involves several parties beyond just the borrower and the lender. Understanding each phase helps you prepare properly and avoid the delays that catch unprepared applicants off guard.
Pre-Construction: Land and Planning
Before construction finance can be arranged, two foundational elements must be in place. First, the borrower must have control of the land — either through outright ownership or through a contract to purchase that can be settled simultaneously with (or prior to) the construction facility. Second, the project must have all necessary planning approvals in place, most commonly a Development Application (DA) approval or a Complying Development Certificate (CDC).
For larger projects, the lender may also require evidence that a Construction Certificate (CC) has been issued or is in progress. The CC confirms that the proposed construction complies with the approved plans and the Building Code of Australia (BCA). Without these approvals, no reputable lender will advance construction funds, because there is no certainty that the build can legally proceed.
Loan Structuring and Approval
Once the planning approvals are secured, the borrower (or their broker) submits a construction finance application to the lender. The application must include comprehensive documentation about the project — plans, specifications, a fixed-price building contract or detailed costings, a quantity surveyor (QS) report, and evidence of the borrower's equity contribution. The lender assesses the project feasibility, the borrower's capacity, and the security position before issuing approval and loan documentation.
For development finance through a private lender, this process can move remarkably quickly. Vertex Capital typically issues an indicative term sheet within hours and can reach full approval within 5 to 10 business days for well-documented scenarios. Banks, by comparison, routinely take 4 to 8 weeks for construction finance approvals due to layered internal credit processes.
The Progress Draw Mechanism
This is the defining feature of construction finance. Rather than receiving the full loan at once, the borrower draws down funds in stages that correspond to completed construction milestones. A typical draw-down schedule for a residential build might follow five or six stages:
- Base/slab stage — excavation, footings, and concrete slab poured (typically 10-15% of construction cost)
- Frame stage — structural framing erected, roof trusses installed (typically 15-20%)
- Lock-up stage — external walls completed, roof on, windows and external doors installed (typically 20-25%)
- Fixing stage — internal linings, cabinetry, plumbing and electrical fit-off (typically 20-25%)
- Practical completion — painting, floor coverings, final fixtures, external works, certificate of occupancy (typically 15-20%)
For larger or more complex developments, the draw-down schedule may include additional stages or be structured around monthly valuations rather than fixed milestones. The exact schedule is agreed between the borrower, the lender, and the quantity surveyor before the loan settles.
Independent Verification
Before each progress draw is released, the work must be independently verified. This is where the quantity surveyor (QS) plays a critical role. The QS inspects the site, confirms that the claimed work has been completed to an acceptable standard, and certifies the draw-down claim. The lender will not release funds until the QS certification is received. This independent verification protects all parties and ensures that the project is genuinely progressing according to plan.
Why Independent Verification MattersThe QS acts as the lender's eyes on the ground. By certifying each draw-down, the QS ensures that the money advanced always corresponds to real, completed work — protecting both the lender's security position and the borrower's project from mismanaged cash flow.
Types of Construction Projects Funded
Construction finance is not a one-size-fits-all product. The structure, costs, and lender appetite vary significantly depending on the type of project being undertaken. Here is how construction finance applies across the most common project categories in Australia.
Single Dwelling Construction
Building a single house on an owned block of land is the most straightforward form of construction finance. The borrower engages a licensed builder under a fixed-price HIA or MBA contract, obtains a QS report to verify the costings, and the lender funds the build through standard progress draws. Banks are generally competitive for this type of project, though borrowers with non-standard income, credit blemishes, or tight timelines may still benefit from a private lender's speed and flexibility.
Dual Occupancy and Duplex Builds
Dual occupancy projects — building two dwellings on a single lot, either for sale or for a combination of owner-occupation and investment — sit at the crossover between standard construction finance and small-scale development finance. Some banks will fund these under their standard construction loan products, while others categorise them as development lending with stricter criteria. Private lenders typically treat dual occupancy builds as straightforward and can be more flexible on the assessment approach.
Townhouse and Unit Developments
Multi-dwelling developments (typically 3 or more dwellings) are almost universally categorised as development finance rather than standard construction lending. The assessment framework shifts from individual borrower capacity to project feasibility: the lender analyses the total development cost, the expected gross realisable value (GRV) of the completed product, the profit margin, the pre-sales position, and the developer's track record. Private lenders have become a dominant force in this segment, particularly for projects under $10 million in total development cost where the major banks have tightened their appetite.
Land Subdivision
Subdivision finance funds the civil works required to convert a parcel of land into individual registered lots — including road construction, stormwater management, utility connections, landscaping, and council contributions. The construction component is entirely civil rather than building-related, and the draw-down stages reflect civil construction milestones (bulk earthworks, road base, kerbing, services, final seal). Subdivision finance is a specialised niche where private lenders often outperform banks on both speed and willingness to lend.
Commercial Construction and Fitouts
Commercial construction covers a broad range of projects: building new commercial premises, refurbishing existing commercial buildings, or completing tenant fitouts in leased spaces. Lender appetite depends on the end use, the tenancy profile, the location, and the overall market conditions. Commercial construction finance through a private lender can be particularly valuable when the project involves mixed-use elements, short construction timeframes, or non-standard lease structures that banks find difficult to assess.
Renovation and Refurbishment
Major renovation projects — particularly structural renovations that transform a property's layout, add additional dwellings (such as a granny flat), or convert a commercial property to residential use — can be funded through construction finance. The key requirement is that the renovation scope is well-defined, the costs have been independently verified, and the end value justifies the total investment. Minor cosmetic renovations are typically funded through standard loan facilities rather than staged construction finance.

Submit Your ScenarioConstruction Finance Costs and Interest Rates
Understanding the true cost of construction finance requires looking beyond the headline interest rate. Construction loans carry a unique cost structure that reflects their staged nature, their higher risk profile compared to standard property lending, and the additional professional services required throughout the project lifecycle.
Interest Rates
Construction finance interest rates in Australia vary significantly depending on the lender type, the project scale, the borrower's profile, and the overall risk assessment. As a general guide for 2026:
- Major banks: Construction loan rates typically range from 6.5% to 8.0% p.a. for borrowers who meet full credit criteria, with rates at the lower end for owner-occupied single dwelling builds and higher for investment or multi-dwelling projects.
- Second-tier and non-bank lenders: Rates generally sit between 7.5% and 10.0% p.a., offering more flexibility on borrower criteria while maintaining a relatively competitive cost of funds.
- Private lenders: Construction finance rates through private lenders like Vertex Capital typically start from 9.5% per annum, ranging up to 14% or more depending on the project risk, LVR, location, and borrower circumstances.
It is important to remember that construction finance interest is charged only on the drawn balance, not the total facility. If you have a $2 million construction facility and have drawn $500,000 at the frame stage, you are paying interest on $500,000 — not $2 million. This significantly reduces the effective interest cost over the life of the build compared to what the headline rate might suggest.
Establishment and Application Fees
Most lenders charge an establishment fee (also called an origination fee or application fee) to cover the cost of assessing the deal, conducting due diligence, and setting up the facility. For construction finance, these fees typically range from 1% to 2% of the total facility amount. On a $1.5 million construction loan, that equates to $15,000 to $30,000. This fee is generally payable at settlement and can often be capitalised into the loan.
Quantity Surveyor Fees
The QS is engaged at two points: initially to assess the construction budget and verify that the builder's costings are reasonable, and then during construction to certify each progress draw. Initial QS reports typically cost between $2,000 and $5,000 depending on project complexity. Ongoing draw-down inspections generally cost $400 to $800 per inspection. For a project with five draw-down stages, total QS costs might range from $4,000 to $9,000 across the life of the project.
Valuation Fees
Lenders require an independent valuation of both the land (as-is value) and the completed project (on-completion value). For residential construction, valuation fees typically range from $500 to $1,500. For development sites or commercial projects, expect $3,000 to $8,000 depending on scale and complexity. Some lenders require an updated valuation at completion, which adds a further cost.
Legal Fees
Both the borrower's and the lender's legal costs apply to construction finance. Lender legal fees for a standard construction facility generally range from $2,000 to $5,000. Development finance with more complex structures (multiple lots, staged settlements, tripartite deeds) can incur significantly higher legal costs. Borrowers should budget separately for their own solicitor's costs in reviewing and executing the loan documentation.
Line Fees and Unused Commitment Fees
Some lenders charge a line fee or unused commitment fee on the undrawn portion of the facility. This compensates the lender for keeping the committed funds available. Not all lenders charge this — at Vertex Capital, we do not apply unused commitment fees on standard construction facilities. It is worth asking about this upfront, as line fees can add materially to the total cost on large facilities with long draw-down periods.
Total Cost ExampleA $1.5M construction facility over 12 months at 10% p.a. with an average drawn balance of 50% would incur approximately $75,000 in interest, $22,500 in establishment fees (1.5%), plus approximately $10,000 in QS, valuation, and legal costs — a total cost of around $107,500. On a project generating $400,000 in profit, that finance cost represents roughly 27% of the margin, well within standard development feasibility parameters.
LVR, LTC, and LGRV Explained
Construction finance uses several key ratios that determine how much a lender will advance against your project. These ratios are more nuanced than the simple loan-to-value ratio (LVR) used in standard property lending, and understanding them is critical to setting realistic expectations about your borrowing capacity.
LVR: Loan-to-Value Ratio
LVR measures the loan amount as a percentage of the property's current market value. In construction finance, LVR is most relevant at the initial stage — it measures the loan against the as-is value of the land before construction begins. For example, if your land is valued at $800,000 and you are seeking a $500,000 loan to begin construction, the initial LVR is 62.5%. Lenders use LVR as one measure of their security margin at the point of initial advance.
LTC: Loan-to-Cost Ratio
LTC is often the primary metric used by private lenders for construction and development finance. It measures the total loan facility as a percentage of the total project cost — which includes land acquisition, construction costs, professional fees, council contributions, and contingency. If the total project cost is $2.5 million and the lender offers a facility of $1.875 million, the LTC is 75%. Private lenders like Vertex Capital typically fund up to 75% LTC for construction projects with strong fundamentals.
LGRV: Loan-to-Gross-Realisable-Value
LGRV (sometimes written as loan-to-GRV or loan-to-end-value) measures the loan facility against the expected value of the completed project. If a development is expected to produce completed dwellings worth a combined $4 million, and the total loan facility is $2.4 million, the LGRV is 60%. This ratio is particularly important for development projects where the completed value significantly exceeds the construction cost. Most lenders cap the LGRV at 55% to 65% depending on the project profile.
In practice, lenders assess all three ratios and apply the most conservative result. A project might qualify for 75% LTC but only 60% LGRV — in which case, the LGRV constraint will determine the maximum facility size. Understanding this interplay is essential for structuring your application correctly from the outset.
| Metric | What It Measures | Typical Maximum | Used For |
|---|---|---|---|
| LVR | Loan vs current land value | 65–75% | Initial security margin |
| LTC | Loan vs total project cost | 70–75% | Equity contribution assessment |
| LGRV | Loan vs completed project value | 55–65% | End-value security margin |
Practical ExampleA developer acquires land for $1M and budgets $1.5M in construction costs, for a total project cost of $2.5M. The completed development is expected to be worth $3.8M. At 75% LTC, the maximum facility is $1.875M. At 60% LGRV, the maximum facility is $2.28M. The lender applies the lower figure: $1.875M at 75% LTC. The developer contributes $625,000 in equity (land value plus cash).
Private Lender vs Bank for Construction Finance
The choice between a bank and a private lender for construction finance is not simply a question of interest rates. It is a question of which funding source best matches the specific requirements of your project, your timeline, and your borrower profile. Each option has distinct advantages, and experienced developers and investors often use both at different stages of their portfolio lifecycle.
| Factor | Private Lender | Bank |
|---|---|---|
| Approval Speed | 5–10 business days | 4–8 weeks |
| Settlement Speed | From 7 days | 6–10 weeks |
| Interest Rates | From 9.5% p.a. | From 6.5% p.a. |
| Credit Assessment | Asset-focused; flexible | Income and credit score driven |
| Income Verification | Light-touch; exit strategy focus | Full financials; 2 years tax returns |
| Max LTC | Up to 75% | Up to 70% |
| Pre-Sales Required | Often not required | Typically 80–100% debt cover |
| Borrower Experience | First-time developers considered | Track record usually required |
| Project Size Range | $300K to $15M+ | $500K to $50M+ |
| Draw-Down Flexibility | Responsive; days not weeks | Can take 2–4 weeks per draw |
| Best For | Speed, complexity, non-standard borrowers | Long-term, lowest-cost standard projects |
When a Private Lender Is the Better Choice
Your land contract has a tight settlement deadline. If you have signed a contract to purchase a development site with a 30-day settlement and your bank is still processing the application, a private lender can step in to settle the land purchase and establish the construction facility simultaneously. Speed is the single most cited reason developers and investors turn to private construction finance.
You have complex or non-standard income. Self-employed borrowers, those with income distributed through trusts and companies, or those with recent changes in their financial structure often fail bank credit models despite being perfectly capable of managing a construction project. Private lenders assess the deal holistically, weighing the project feasibility and exit strategy ahead of the borrower's personal income documentation.
You are a first-time developer. Banks typically want to see a track record of completed projects before approving development finance. If this is your first construction project, a private lender may be more willing to assess the deal on its merits — particularly if you have engaged experienced professionals (builder, project manager, architect) to support the delivery.
Pre-sales are not yet in place. Banks routinely require pre-sales covering 80% to 100% of the debt before they will approve construction finance for multi-dwelling developments. Private lenders can often proceed without pre-sales, provided the project feasibility is strong and the location has demonstrable demand. This allows developers to begin construction earlier and potentially achieve higher sale prices on completed stock rather than off-the-plan contracts.
The bank said no but the deal is viable. Bank declines do not always mean a project is flawed. They often mean the borrower or the project does not fit the bank's rigid credit policy. A private lender who assesses each deal individually can identify viability where a bank's automated system cannot.
When a Bank Is the Better Choice
You meet all standard lending criteria. If you have clean credit, strong PAYG or verified self-employed income, a proven development track record, pre-sales in hand, and no urgency on timing, a bank will deliver the lowest cost of funds for your construction project.
The project is straightforward. A single owner-occupied dwelling on a standard residential lot with a tier-one builder and a fixed-price contract is squarely in the bank's comfort zone. The lower interest rate over a 9-to-12-month build period can save meaningful capital.
You have time. If your project timeline allows for 6 to 10 weeks of approval processing without impacting land settlement deadlines or construction start dates, the bank's lower rate makes financial sense. Time pressure is the primary factor that shifts the equation toward private lending.
Not Sure Which Option Suits Your Project?
Submit your construction scenario and we will provide an honest assessment of whether private finance or bank finance is the better fit.
Get an AssessmentWhat You Need to Apply
Construction finance applications are more documentation-intensive than standard property loans because the lender must assess not only the borrower but also the viability of the construction project itself. Having the right documents prepared before you apply can dramatically reduce approval timeframes — particularly with a private lender where speed is a core advantage.
Development Application (DA) or Complying Development Certificate (CDC)
The planning approval is the foundation of any construction finance application. A DA approved by the local council (or a CDC issued by a private certifier) confirms that the proposed construction is permitted under the relevant planning controls. Without this approval, no lender can advance construction funds. For projects requiring a DA, ensure you also have any conditions of consent documented and a plan for how they will be satisfied.
Architectural Plans and Specifications
Detailed architectural drawings showing floor plans, elevations, sections, and site plans are required. For larger developments, the plans should be accompanied by a full specification document that details materials, finishes, fixtures, and construction methodology. These documents form the basis of the QS cost assessment and the valuer's on-completion valuation.
Fixed-Price Building Contract
Lenders strongly prefer a fixed-price building contract (HIA, MBA, or equivalent industry-standard form) with a licensed and insured builder. The contract should clearly itemise the scope of works, the total contract price, the progress claim schedule, the construction timeline, and any provisional sums or prime cost items. For owner-builder projects, additional documentation around cost management and project delivery capability is typically required.
Quantity Surveyor (QS) Report
An independent QS report is required for virtually all construction finance applications. The QS reviews the builder's contract (or detailed costings for owner-builder projects) and provides a professional opinion on whether the construction budget is reasonable, complete, and achievable. The QS report also establishes the draw-down schedule and serves as the benchmark against which progress claims will be assessed throughout the build.
Valuation (As-Is and On-Completion)
The lender will commission an independent valuation covering the current as-is value of the land and the projected on-completion value of the finished development. The valuer assesses both figures based on comparable sales evidence, market conditions, and the proposed scope of construction. The on-completion value is particularly important as it determines the LGRV and confirms the feasibility of the exit strategy.
Borrower Financial Documentation
The extent of borrower financial documentation varies by lender type. Banks require comprehensive financials: two years of tax returns, profit and loss statements, balance sheets, and asset/liability declarations. Private lenders take a lighter approach, typically requesting:
- Identification documents (driver's licence, passport)
- A summary of assets and liabilities
- Details of the proposed exit strategy (sale of completed product, refinance to a bank, or other)
- Evidence of equity contribution (cash in bank, existing property equity, or land ownership)
- For developers: a track record summary of previous projects (if applicable)
Builder's Credentials
Lenders will verify that the engaged builder holds a current builder's licence, carries adequate insurance (including home warranty insurance where applicable and public liability coverage), and has the capacity to deliver the project. For development projects, the builder's financial standing and track record may also be assessed. Engaging a reputable, well-capitalised builder strengthens your application significantly.
Project Feasibility Study
For multi-dwelling developments and subdivisions, a project feasibility study (also called a development feasibility or residual land value analysis) is typically required. This document maps out all project costs, expected revenues, and projected profit margin. Most private lenders want to see a minimum profit margin of 15% to 20% on total development cost for the project to be considered viable. Vertex Capital can assist borrowers and brokers in structuring feasibility models that meet lender requirements.
Pro Tip for Faster ApprovalPrepare your QS report, building contract, and DA approval before submitting your application. The number one cause of construction finance delays is incomplete documentation. When these core documents are ready, a private lender can issue approval in days rather than weeks.
The Construction Draw-Down Process
Once your construction finance facility is in place and the build has commenced, the draw-down process governs how funds flow from the lender to the project. This process repeats at each construction milestone and involves a specific sequence of steps that must be followed precisely to avoid costly delays.
Step 1: Builder Submits a Progress Claim
When the builder completes a milestone (such as the slab stage or frame stage), they submit a progress claim to the borrower. The claim details the work completed, the percentage of the total contract now finished, and the amount being claimed. The claim should correspond to the agreed draw-down schedule established at the outset of the project.
Step 2: Borrower Reviews and Approves
The borrower (or their project manager) reviews the progress claim to confirm that the work described has been completed to an acceptable standard and that the claim amount aligns with the contract schedule. Any discrepancies should be resolved with the builder before the claim is forwarded to the lender. It is the borrower's responsibility to ensure they are satisfied with the quality of work before authorising the draw-down request.
Step 3: QS Inspection and Certification
The borrower submits the progress claim to the lender, who then engages the QS to conduct a site inspection. The QS visits the construction site, verifies that the claimed work has been completed, assesses the quality of workmanship, and confirms that the costs are consistent with the original budget. The QS then issues a certification recommending (or amending) the draw-down amount.
Step 4: Lender Releases Funds
Upon receipt of the QS certification, the lender processes the draw-down and releases the funds. With a private lender like Vertex Capital, draw-down processing typically takes 2 to 5 business days from the date of QS certification. Banks can take significantly longer — sometimes 2 to 4 weeks per draw-down, which can create cash flow pressure for builders and delay subsequent construction stages.
Step 5: Builder Is Paid
The released funds are used to pay the builder's progress claim. Depending on the loan structure, funds may be disbursed directly to the builder, paid into a solicitor's trust account, or deposited into the borrower's account with a direction to pay the builder. The precise mechanism is established in the loan documentation.
The Draw-Down Cycle Repeats
This process repeats for each subsequent construction stage until the project reaches practical completion and the final draw-down is released. It is not uncommon for a typical residential construction project to involve 5 to 6 draw-downs, while larger developments may require 10 or more over the course of the build.
The speed of draw-down processing is a significant differentiator between lenders. Slow draw-downs create cash flow problems for builders, who may then deprioritise your project in favour of others where they are being paid on time. This cascading effect is one of the less obvious but highly impactful reasons that borrowers choose private lenders for construction finance — faster draw-downs keep builders happy, which keeps the project on schedule.
Draw-Down Speed MattersA builder waiting 3 weeks for a bank to process a $200,000 progress claim is a builder who may shift their best trades to another project. Fast draw-down processing from a private lender — typically 2 to 5 days — keeps the builder's cash flow healthy and your project on track.
Common Construction Finance Scenarios
To illustrate how construction finance works in practice, here are several scenarios that represent the types of deals Vertex Capital assesses regularly. Each scenario demonstrates different aspects of the construction finance process and highlights the situations where private lending delivers the most value.
Scenario 1: Townhouse Development in a Melbourne Growth Corridor
A developer has purchased a 700sqm site in Melbourne's south-east for $920,000 and holds DA approval for four townhouses. Total construction cost is budgeted at $1.6 million, with an expected GRV of $3.4 million (four townhouses at $850,000 each). The developer has $620,000 in equity (land plus cash) and needs a construction facility of $1.9 million to cover the remaining land debt and all construction costs.
The bank declined the application because the developer had only completed one previous project and the bank's policy required a minimum of three. Vertex Capital assessed the project on its merits: the feasibility was strong (25% profit on cost), the builder was experienced and well-capitalised, and the exit strategy (individual sales) was supported by strong comparable evidence in the area. The facility was approved within 7 business days at 75% LTC.
Scenario 2: Owner-Builder Single Dwelling in Regional NSW
A self-employed tradesperson owns a block of land in the Central Coast region valued at $480,000 and plans to construct a custom four-bedroom home with a construction budget of $620,000. As an owner-builder, the borrower will manage subcontractors directly rather than engaging a head contractor. Total project cost is $1.1 million and the completed property is expected to be worth $1.35 million.
Banks were reluctant to fund the project for two reasons: the borrower's self-employed income was distributed through a discretionary trust (making it difficult to verify under standard serviceability models), and the owner-builder structure added perceived risk. Vertex Capital structured a facility at 70% LTC with a detailed draw-down schedule tied to QS milestones, ensuring that each stage was independently certified despite the absence of a head contractor. The borrower's exit strategy was to refinance the completed property to a bank within 3 months of completion.
Scenario 3: Urgent Land Settlement with Concurrent Construction Finance
An experienced developer identified a DA-approved development site being sold by a receiver. The receiver required settlement in 21 days with no extensions. The developer needed both land acquisition finance and a construction facility for the approved 6-unit development. Total deal size was $4.2 million (land at $1.4M, construction at $2.8M).
No bank could meet the 21-day land settlement deadline, let alone establish a concurrent construction facility. Vertex Capital issued an indicative term sheet within 4 hours of receiving the scenario, completed due diligence in parallel with valuation and QS engagement, and settled the land purchase on day 18. The construction facility was documented simultaneously, allowing the developer to commence building immediately after settlement. A bridging finance structure was used for the initial land settlement component, rolling into the full construction facility once the build commenced.
Scenario 4: Subdivision Finance for a 12-Lot Rural Residential Project
A landowner in south-east Queensland held a 5-acre parcel with DA approval for a 12-lot rural residential subdivision. The civil works budget (roads, stormwater, sewer, water, power, telecommunications, landscaping, and council contributions) was $1.8 million. The land was valued at $1.2 million, and the completed lots were expected to sell for a combined $4.5 million.
The borrower had credit impairment from a business downturn three years earlier, which eliminated bank funding as an option. Vertex Capital assessed the project feasibility (strong 40%+ profit margin), confirmed the civil works budget through an independent QS, and approved a facility at 65% LTC. Draw-downs were structured around civil construction milestones rather than building stages, and the borrower's exit strategy was staged lot sales as each lot achieved title registration.
Scenario 5: Commercial Fitout with Tight Lease Commencement Date
A hospitality operator had signed a lease for a 350sqm restaurant premises in Sydney's inner west, with a lease commencement date 8 weeks away. The fitout budget was $580,000, and the operator needed finance to cover 75% of the cost. The remaining 25% was funded from the operator's own capital. The bank could not approve a commercial loan for a fitout within the timeframe, particularly given the operator's business was a new entity with limited trading history.
Vertex Capital structured a short-term construction facility secured against a second mortgage over the operator's residential investment property, with the fitout costs drawn down in three stages as the fitout progressed. The facility was approved in 5 business days and settled in 10, giving the operator sufficient time to complete the fitout and open on schedule. The exit strategy was refinance to a business lender once the restaurant had established 6 months of trading history.

Submit Your ScenarioFrequently Asked Questions
Construction finance is a purpose-built lending product designed to fund the physical construction of buildings, renovations, or civil works. Unlike a standard property loan where the full amount is disbursed at settlement, construction finance is drawn down in stages (called progress draws) as the build reaches predetermined milestones. This staged approach protects both the lender and the borrower by ensuring funds are only released as work is completed and independently verified by a quantity surveyor. Interest is charged only on the drawn balance, not the total facility.
The equity contribution required depends on the lender type and the project. Banks typically require 20% to 30% of total project costs for construction finance. Private lenders like Vertex Capital generally fund up to 75% of total development costs (loan-to-cost), meaning you need a minimum of 25% equity. This equity can come from land you already own, cash, or a combination of both. For some projects with strong fundamentals, lenders may accept the existing land value as the primary equity contribution, reducing the cash required from the borrower.
Yes, through a private lender. Banks apply strict credit and income assessment criteria for construction finance, which often excludes self-employed borrowers, those with credit impairments, or borrowers with complex income structures. Private lenders like Vertex Capital take an asset-focused approach, assessing the feasibility of the project, the value of the security, and the strength of the exit strategy rather than relying solely on credit scores or PAYG income. Defaults, judgments, and non-standard income are assessed on a case-by-case basis.
A quantity surveyor (QS) report is an independent assessment of the anticipated construction costs for your project. It itemises every component of the build — from foundations and framing to finishes and landscaping — and provides a professional opinion on whether the builder's contract price is reasonable and achievable. Lenders require a QS report to verify that the construction budget is realistic and that there are sufficient funds to complete the project. The QS also monitors progress during construction to certify each draw-down claim before the lender releases funds.
Approval timelines vary significantly between lender types. Banks typically take 4 to 8 weeks to approve construction finance due to their extensive credit assessment, income verification, and internal review processes. Private lenders can issue indicative term sheets within hours and achieve full approval in 5 to 10 business days, with settlement from 7 days for straightforward scenarios. The speed advantage of private construction finance is particularly valuable when land contracts have tight settlement deadlines or when construction timelines are already committed.
Cost overruns are one of the most common risks in construction projects. If your builder exceeds the original budget, you will generally need to fund the difference from your own resources, as lenders will not automatically increase the facility. This is why lenders require a contingency allowance (typically 5% to 10% of construction costs) built into the original budget. Working with a reputable builder, obtaining a fixed-price contract where possible, and having the budget independently verified by a quantity surveyor all help mitigate the risk of overruns. If significant cost overruns do occur, speak with your lender early — it may be possible to request an increased facility, subject to a revised feasibility assessment and additional equity contribution.
Start Your Construction Project
Construction finance is a specialised, powerful tool that turns approved plans into completed buildings. Whether you are constructing a single dwelling, delivering a townhouse development, subdividing land, or fitting out a commercial premises, the right finance structure makes the difference between a project that flows smoothly and one that stalls at every stage.
If you have read this far, you now understand more about construction finance than most borrowers who walk into a bank branch. You know how progress draws work, why the QS is critical, how LVR, LTC, and LGRV interact to determine your borrowing capacity, and when a private lender delivers a better outcome than a bank.
