Property development usually becomes expensive well before the first slab is poured. Site costs, consultant fees, council contributions, interest, contingencies and construction progress claims all need funding at different stages, and the wrong structure can put pressure on the entire project. If you are working out how to fund property development, the starting point is not simply finding a lender. It is understanding what the project needs, when it needs it, and how that finance structure will hold up from acquisition through to exit.
For Australian borrowers, development funding is a specialised area of lending. It sits well beyond a standard investment loan because the lender is assessing not just your income and assets, but the feasibility of the project itself. That means your funding options, leverage limits, documentation requirements and pricing can vary significantly depending on the size of the development, your experience, the end product, and your exit strategy.
How to fund property development starts with the capital stack
Every development has a capital stack. In simple terms, that is the mix of money going into the deal. Most projects are funded through some combination of developer equity, senior debt, and sometimes mezzanine or private funding. The right balance depends on risk, cost and lender appetite.
Developer equity is usually the first piece. This can come from cash, equity released from existing property, or funds contributed by business partners or investors. Lenders want to see genuine contribution from the developer because it demonstrates commitment and reduces their risk. In many cases, this equity covers the deposit, acquisition costs, early-stage soft costs and part of the required project contribution.
Senior debt is typically the main source of funding. This is the primary construction or development loan, usually provided by a bank or non-bank lender. It may fund a percentage of the site value, construction costs and, in some cases, interest capitalisation and GST requirements. However, it will rarely cover the entire project cost. That gap is where developers can come unstuck if they have focused too heavily on borrowing capacity and not enough on total capital requirements.
Mezzanine finance sits behind the senior lender and above developer equity. It can help bridge a shortfall where the senior lender will not advance enough funds, but it comes at a higher cost and adds complexity. Used strategically, it can make a viable project proceed. Used poorly, it can weaken profitability and increase pressure on the exit.
The main funding options for Australian developers
Bank development finance is often the most competitive on price, but it is also the most conservative. Major banks and some second-tier lenders generally prefer lower-risk projects, stronger borrowers, clear feasibility, and often experienced developers. They may require pre-sales for certain projects, detailed quantity surveyor reports and strict cost controls before approving funding.
Non-bank development finance can be more flexible. These lenders may consider smaller developers, unusual securities, shorter project timeframes or projects that fall outside mainstream policy. The trade-off is that pricing is usually higher, and due diligence can still be intensive. For many borrowers, non-bank lending is not a second-best option. It is simply a better fit for the project profile.
Private lending can be relevant where timing is critical or the project has complexity that mainstream lenders will not accept. This might include urgent settlements, incomplete documentation at an early stage, or transitional funding while a longer-term structure is arranged. Private debt can solve a timing problem, but it should be approached carefully because rates, fees and default terms can materially affect the project.
Joint venture funding is another path. Rather than increasing debt, some developers bring in an equity partner who contributes capital in exchange for a share of profits or ownership. This can reduce leverage and strengthen the project from a lender's perspective, but it also means sharing upside and giving up some control.
What lenders assess before approving development finance
Understanding how to fund property development means understanding how lenders think. They do not approve projects based on site value alone. They assess the borrower and the development together.
Serviceability still matters, but feasibility is central. Lenders want to know the project is commercially sound. They look closely at total development cost, gross realisation value, contingency allowances, builder credentials, planning status, market demand and the projected margin. If the numbers are too tight, the deal may be declined even if the borrower has strong assets.
Developer experience is another major factor. An experienced developer with a clear track record may access better leverage, sharper pricing or more flexible terms than a first-time applicant. That does not mean new developers cannot obtain funding, but they often need a simpler project, stronger balance sheet, or support from experienced consultants and builders to improve lender confidence.
The security position also matters. Some lenders will take first mortgage security over the development site only. Others may require additional security, particularly if the project is higher risk or leverage is stretched. This is where structure becomes strategic. A facility that looks attractive on headline terms can be less appealing once cross-collateralisation or extra guarantees are considered.
Pre-sales, equity and cash flow pressure
For townhouse, unit and mixed-use developments, pre-sales can play a significant role. Many lenders use them as evidence of market demand and future debt repayment. A lender may require a certain debt coverage ratio from qualifying pre-sales before construction funding is released.
Pre-sales help de-risk the project, but they are not always straightforward. The lender may discount the contract values, assess the strength of the purchasers, or reject related-party sales. Developers also need to balance lender requirements with project timing. Waiting for enough pre-sales can delay commencement, while launching too early may affect pricing if the project is not yet market-ready.
Equity is equally important, and not just in percentage terms. Developers often underestimate how much cash is needed outside the formal loan. There are consultant fees, application fees, legal costs, holding costs, valuation expenses and contingency overruns that can place real pressure on liquidity. A deal can look well-funded on paper and still struggle in practice if working capital is too tight.
Common mistakes when structuring development funding
One of the most common mistakes is focusing only on the interest rate. Development finance should be assessed on total structure, not headline price alone. Loan-to-cost ratio, timing of drawdowns, interest capitalisation, pre-sale requirements, fees, reporting obligations and extension terms can all affect the real cost and practicality of the facility.
Another mistake is relying on optimistic feasibility assumptions. If construction costs are understated, sale values are aggressive, or contingencies are too light, the funding application may fail under due diligence. Even worse, the project may proceed and later run into margin pressure. Lenders generally prefer conservative assumptions for good reason.
Borrowers also run into trouble when they seek finance too late. Development loans involve more moving parts than standard property lending. You may need town planning documents, fixed-price building contracts, QS reports, valuations, entity documents and detailed financials. Leaving funding to the last minute can create unnecessary urgency and narrow your lender options.
A practical way to approach how to fund property development
The strongest approach is to work backwards from the exit. If the project is a build-to-sell development, the lender will want confidence that the sales process and end values support repayment. If it is a build-and-hold strategy, the key question becomes whether the completed asset can be refinanced onto an investment or commercial term loan at an acceptable valuation and income position.
From there, the structure should be built around the project's risk profile. A straightforward duplex or townhouse project may suit a relatively conventional development facility. A more complex site with planning risk, staged construction or mixed-use components may require a layered funding solution.
It is also worth stress-testing the numbers before you apply. Ask what happens if build costs rise, the project runs three months late, or sale values soften. Good structuring is not just about getting approved. It is about giving the project enough resilience to absorb normal development risk.
This is where specialist guidance matters. A strategic broker or finance adviser can help position the application properly, test lender appetite early, and identify where the structure may need adjusting before it reaches credit. For borrowers navigating bank, non-bank and private options, that advice can save both time and margin. At The Finance Office, this is typically where the value sits - not only sourcing a lender, but shaping a structure that supports the broader project outcome.
Property development finance rewards preparation. The more clearly you understand your capital stack, feasibility, exit and risk points, the easier it becomes to choose funding that fits the project rather than forcing the project to fit the funding. If you are serious about developing, treat the finance structure as part of the development strategy itself.
