Finance for multi-unit development projects

Building multiple dwellings on a single block operates differently from standard home construction finance.

If you're a PAYG professional looking at a duplex, triplex, or small block of townhouses, the funding arrangement changes because lenders view multi-unit development as higher complexity than a single dwelling. The main difference shows up in how funds are released, what documentation you'll need before settlement, and which lenders will actually consider your application.

What Makes Multi-Unit Construction Finance Different

Lenders release funds through a progressive drawdown tied to build stages, but they require council approval and detailed costings before you settle on the land. Where a standard house and land package might give you twelve months to commence building, multi-unit projects typically require that you commence building within a set period from the Disclosure Date, often around six months, with a registered builder already engaged.

Consider someone purchasing a block in Balgowlah zoned for dual occupancy. They've found suitable land at $1.8 million and have costings for two three-bedroom townhouses at $850,000 combined. Most lenders won't settle the land purchase until they've sighted council plans, the fixed price building contract with a registered builder, and a development application showing either approval or acceptable conditions. This differs from a single dwelling where you might buy land first and sort construction details afterward.

How the Progressive Drawing Fee and Interest Structure Works

You only charge interest on the amount drawn down at each construction stage, not the full loan amount from day one. A typical construction loan for multi-unit projects releases funds in five to seven instalments aligned with your progress payment schedule. Each drawdown triggers a Progressive Drawing Fee, usually between $150 and $400 per inspection, where the lender arranges a progress inspection to confirm the work matches the claim.

The interest-only repayment options during construction mean you're servicing only the debt that's actually been drawn. If your total facility is $2.65 million but only $1.9 million has been released for land and initial stages, your interest applies to that lower figure. This structure helps manage cash flow during the twelve to eighteen months most duplex or townhouse builds require, particularly when you're still working full-time and can't access pre-sales to offset costs the way larger developers might.

Fixed Price Contracts Versus Cost Plus Arrangements

Most lenders providing construction finance for multi-unit projects insist on fixed price building contracts rather than cost plus arrangements. A fixed price contract locks in the total build cost, which gives the lender certainty about the final loan amount and reduces their risk if the project runs over budget.

In a scenario where you're building three townhouses in Caringbah, your builder quotes $1.2 million as a fixed price. If during construction they encounter rock that adds $60,000 to excavation costs, that's absorbed by the builder under a fixed price contract. Under a cost plus contract, where you pay actual costs plus a builder's margin, you'd wear that variation. Lenders know this, which is why access to construction loan options from banks and lenders across Australia narrows considerably once you move away from fixed pricing. Some non-bank lenders will consider cost plus, but expect higher interest rates and lower borrowing capacity.

The Reality of Progress Payments and Instalments

Your progress payment finance typically splits the build into stages like base, frame, lock-up, fixing, and practical completion. Each stage has a defined scope, and your builder claims payment only when that work is verified. The lender sends someone to confirm the stage matches the claim before releasing funds, protecting both you and them from paying for incomplete work.

The timing matters more than many PAYG borrowers expect. If stage three is valued at $280,000 but takes two weeks longer than scheduled, you're still servicing interest on earlier drawdowns while the builder waits for their payment. This can create tension if your builder employs plumbers, electricians, and other sub-contractors who expect prompt payment. In our experience, having a buffer of around 10% beyond the contracted amount helps manage variations or timing delays without derailing the project.

When Land and Construction Packages Don't Apply

A land and construction package, common for project home buyers, bundles the land purchase and build into one pre-arranged transaction. This doesn't suit multi-unit development because you're typically working with custom design tailored to the block's dimensions and zoning requirements, not a standard design from a volume builder's catalogue.

If you've identified a property in Balmain that could accommodate two semi-detached homes, you need an architect or designer to create plans that satisfy council, heritage, and building code requirements specific to that site and that inner-city location. This custom approach means engaging your own registered builder and managing the development application process yourself or through a planner. Lenders structure the funding around these realities, which is why multi-unit construction funding sits outside the standard land and build loan category.

How PAYG Income Affects Borrowing Capacity for Development

Lenders assess your capacity to service the debt through construction and after completion. If you're planning to sell both units post-completion, some lenders will factor in anticipated sale proceeds when calculating risk, but they still assess serviceability on your PAYG income during the build.

Your taxable income needs to comfortably cover interest on the progressive draws. If you earn $180,000 as a PAYG professional and you're drawing down $2.2 million over twelve months, the interest during construction might average $7,000 to $9,000 monthly depending on how quickly stages are reached. Lenders want to see that you can meet these payments from salary without selling assets or relying on bonuses. They also consider your existing commitments, so if you're carrying an investment loan or owner-occupied debt elsewhere, that reduces what you can service on the development.
