Development finance

Property development finance: how it works, and how to get it right

From a duplex or a small subdivision to townhouses, apartments and commercial builds, development finance works differently to a home loan. Here is how lenders size a project, what they ask for, how the money flows, and where a broker earns their keep.

What development finance covers

Development finance is lending to buy a site and build on it, then repay from selling or refinancing what was built. It covers small projects (a knock down and two townhouses, a duplex, a few lots of subdivision) right through to apartment buildings, industrial estates and commercial builds. The same project often needs more than one loan over its life:

How a development loan differs from a home loan

A home loan is repaid from your income. A development loan is usually repaid from the project itself. ASIC describes development lending as negative cash flow lending: there is no income to pay interest while the project is built, so interest is usually capitalised (added to the loan) or paid from the loan as it is drawn, and the loan is repaid by selling or refinancing the finished project. ASIC notes the full life of a project may take 36 to 60 months.

That is why a development lender looks hardest at the project: the site, the approvals, the builder, the costs, the end value and whether the sales will settle, as well as the developer's experience and the money they are putting in.

The numbers lenders look at

Example project: how the ratios lenders look at are worked out
ItemAmount
Site purchase$1,200,000
Construction$2,400,000
Professional fees, approvals, contributions and contingency$400,000
Interest and finance costs during the project$300,000
Total development cost$4,300,000
Expected sale value of everything built (gross realisation value)$5,600,000
Selling costs (3% in this example)$168,000
Profit before tax$1,132,000
Loan in this example$3,000,000
Loan as a share of total cost (loan to cost)69.8%
Loan as a share of the end value (loan to gross realisation value)53.6%
Your own money in (equity)$1,300,000
Profit as a share of total cost (margin on cost)26.3%
Example figures chosen to show the arithmetic, not typical costs, values or lender limits. Enter figures consistently (all including GST or all excluding it) and ask your accountant about GST. Each lender sets its own limits for these ratios.

Run your own numbers

Starts with the example above. Replace the figures with your project’s, all including GST or all excluding it.

Total development cost
$4,300,000
Profit before tax
$1,132,000
Margin on cost
26.3%
Loan to cost
69.8%
Loan to end value
53.6%
Your own money in
$1,300,000

Arithmetic only, before tax. Each lender sets its own limits for these ratios and values the project itself, so treat this as a starting point for the conversation, not an offer of finance.

How a ratio is measured matters. ASIC has pointed out that a loan quoted on a completion basis at, say, 70% of cost is likely to be closer to 80 to 90% during construction. Lenders each measure and set these ratios their own way, which is one reason two lenders could offer very different terms on the same project.

Banks, non bank lenders and private credit

Banks fund many development projects, particularly well located ones with an experienced developer and strong presales. Non bank lenders and private credit funds have become a large part of the market too. ASIC estimated Australia's private credit market at around $200 billion in 2024, with roughly half focused on real estate, including construction and development finance. The Reserve Bank notes that Australian private credit funds are more exposed to real estate, including construction and development, than funds in the United States.

ASIC notes that after the global financial crisis, bank capital rules made development lending less attractive for banks, and that private credit brings a different risk appetite with fewer terms and conditions, giving some borrowers access to funding they may not otherwise have. That flexibility generally comes at a higher price, so compare the full cost. The right lender depends on the project, the timing and the developer.

Presales: no fixed rule

In February 2025 APRA clarified that its 2017 reference to banks requiring presales of at least 100% of the debt was not a minimum requirement or expectation: it described what banks were doing at the time. Presales still matter to lenders, but each sets its own requirement. The Reserve Bank's October 2026 review noted some lenders have since loosened presale requirements for residential projects.

What lenders usually ask for

  1. A feasibility study: costs, end values, timing and profit, ideally in a recognised format.
  2. Approvals: the development approval and its conditions, or a clear path to them.
  3. The build contract and builder: usually a fixed price contract with a builder the lender accepts, plus a quantity surveyor's report on costs.
  4. A valuation: arranged by the lender, on an as is and an as if complete basis.
  5. Presales or a sales plan: contracts, deposits and the marketing strategy.
  6. The developer's track record and financial position: past projects, assets, liabilities and the equity going in.
  7. The ownership structure: the company or trust that will borrow, and the guarantors.

Regulated or not: who the borrower is matters

Most development loans are made to a company or trust for business purposes, and ASIC states that loans to companies are not covered by the consumer credit legislation. But ASIC also says a loan to an individual to buy land and build homes on it will generally be regulated, even when the person borrows to develop several properties. The structure you buy in changes the rules that apply, the protections you have and sometimes which lenders will look at the deal, so get accounting and legal advice on structure before you sign for the site.

GST is part of the feasibility

Selling new residential premises usually involves GST. Since 1 July 2018, buyers of new residential premises or potential residential land generally withhold GST at settlement and pay it straight to the ATO: generally one eleventh of the price, or 7% where the margin scheme applies. That changes the cash you receive at settlement, so it belongs in the feasibility and the lender's cash flow from day one. Your accountant should advise on GST and the margin scheme for your project.

The risks lenders price in

ASIC notes construction and development finance has made up the majority of credit losses in past downturns, and is regarded as higher risk than lending on income producing property. That is why development loans cost more than home loans and why lenders look so closely at costs, builders and sales. Building in contingency, choosing a builder with a sound balance sheet and having a plan for unsold stock are what keep a project financeable when conditions change.

Common questions

How much of a development could a lender fund?

It depends on the lender, the project and the developer. Lenders look at the loan as a share of total development cost and as a share of the finished value, and at presales and your experience. Banks and private lenders set very different limits, which is why comparing them matters.

What is gross realisation value?

The total expected sale value of everything the project will produce, usually set by an independent valuer. Lenders compare the loan to it to see how much room there is if prices fall.

Do I need presales to get development finance?

Not always. APRA confirmed in February 2025 that it sets no minimum presales requirement for banks, while noting presales play an important role in sound lending. Each lender sets its own requirement, and the Reserve Bank has noted some lenders have loosened presale requirements for residential projects.

Is interest paid monthly on a development loan?

Usually not. Because the project earns no income while it is built, interest is commonly capitalised (added to the loan) and repaid from sales or a refinance at the end.

Is development finance regulated like a home loan?

Loans to companies for business purposes are generally not covered by the consumer credit legislation. Loans to individuals to buy land and build homes generally are, according to ASIC. Get advice on structure before you buy the site.

Could I get development finance for my first project?

Possibly. First time developers usually need more equity, a strong builder, a conservative feasibility and sometimes an experienced partner or project manager. Smaller projects such as a duplex or a few townhouses are a common first step.
