What are Multi-Unit Development Site Loans

What Construction Finance Covers for Multi-Unit Development Sites

Purchasing a multi-unit development site requires two separate funding components: the land acquisition and the construction phase. Most lenders structure this as a land and construction package where you settle on the site first, then draw down funds progressively as building work advances across each unit.

Consider a buyer acquiring a 1,012 square metre block in Moorooka zoned for four townhouses. The site costs $1.2 million, with construction budgeted at $1.6 million across all units. A typical structure involves settling the land purchase with a 20% deposit, then accessing the remaining funds through a progressive drawdown as each stage of construction reaches completion. The lender will only charge interest on the amount drawn down at each stage, which reduces carrying costs during the build period compared to drawing the full loan amount upfront.

Lenders assess both the site value and the end value of completed units when determining how much they'll lend. For multi-unit projects, most require a registered builder working under a fixed price building contract, with funds released according to a progress payment schedule that aligns with construction milestones. The initial land component typically settles through standard mortgage documentation, while the construction loan operates on different terms that account for the staged nature of the build.

Development Application Requirements Before Finance Approval

Lenders will not proceed with unconditional finance approval until you have council approval in place. Development application approval confirms that your proposed multi-unit project complies with local planning schemes, and lenders need this certainty before committing funds.

For a site in Kedron approved for six units, the development application process took four months through Brisbane City Council. The finance application couldn't move to unconditional approval until the council plans were stamped and all conditions satisfied. Some lenders will provide conditional approval based on lodged development applications, but this isn't binding and leaves you exposed if the application is refused or substantially amended.

Most banks require you to commence building within a set period from the Disclosure Date, typically 12 months. If your development application is still under assessment when you're ready to apply for finance, factor this timeline into your funding strategy. Delays in council approval directly affect when construction can start and when you can access funds.

How Progressive Drawdown Works Across Multiple Units

Construction funding releases in instalments tied to verified completion stages rather than as a lump sum. For multi-unit developments, lenders structure the progress payment schedule to reflect work completed across the entire project, not individual units.

A typical progress payment schedule for a four-unit development in Coorparoo might include: base stage at 10%, frame stage at 15%, lock-up stage at 35%, fixing stage at 25%, and practical completion at 15%. The lender engages a quantity surveyor or building inspector to conduct a progress inspection before releasing each payment. Funds go directly to pay sub-contractors, including plumbers, electricians, and other trades, with payment usually made to the builder who then distributes to contractors according to the cost plus contract or fixed price contracts in place.

Each drawdown attracts a Progressive Drawing Fee, typically between $300 and $500 per inspection depending on the lender. With five to six drawdowns across a multi-unit project, these fees add $1,500 to $3,000 to your total borrowing costs. Some lenders cap the number of drawdowns they'll support, which can create cash flow issues if your builder requires more frequent payments than the construction draw schedule allows.

Interest accrues only on funds already drawn. If you've drawn $400,000 for land and base works but your total facility is $2.8 million, you're only paying interest on the $400,000 until the next drawdown. Most lenders offer interest-only repayment options during construction, with principal and interest repayments commencing once the development reaches practical completion or when you begin selling individual units.

Loan Amount Calculations for Development Sites

Lenders assess loan amount based on the lower of purchase price plus construction costs, or the end value of completed units. For multi-unit developments, the loan-to-value ratio typically caps at 70-75% for development finance, though some lenders go to 80% if you have significant development experience or strong financials.

A buyer looking at a Wynnum site for three townhouses might face these figures: land at $850,000, construction at $1.05 million across all three units, giving a total project cost of $1.9 million. If the combined end value of the three completed townhouses is $2.4 million, the lender would calculate their maximum loan based on 70% of $1.9 million, which is $1.33 million. This means you need $570,000 in cash or equity to proceed. That equity might come from existing property, cash savings, or a combination.

Owner builder finance exists but is substantially harder to obtain for multi-unit projects. Most lenders require a registered builder with relevant qualifications and insurance. If you're planning to manage trades yourself, expect loan-to-value ratios to drop to 60% or lower, with some lenders declining entirely. The risk profile for owner-managed multi-unit developments is too high for most banks to support.

Interest Rate Structures During and After Construction

Construction loan interest rates typically sit 0.5% to 1.0% higher than standard home loans due to the additional risk and administration involved in progressive drawdowns. Rates may be variable during construction, switching to either fixed or variable once the development reaches practical completion and converts to a standard investment loan or owner-occupied mortgage.

For sites in growth areas like Fitzgibbon or Carseldine, where multi-unit developments are increasingly common due to proximity to the Carseldine railway station and local infrastructure, lenders assess both the construction phase risk and the end use. If you're planning to sell all units upon completion, the lender structures the loan differently than if you're retaining one or more as rental properties. Retained units can convert to standard investment lending at current variable rates, while units earmarked for sale need to settle within agreed timeframes to avoid penalty rates or forced conversion.

Some lenders offer construction to permanent loan products that transition automatically from construction to standard mortgage terms once building completes. This avoids the need to refinance or reapply, though the initial interest rate during construction still applies to drawn funds.

Pre-Sales and Lender Requirements for Multi-Unit Projects

Lenders assessing multi-unit development sites often require evidence of pre-sales before approving finance, particularly for projects beyond three units. A pre-sale is a contract to sell a unit off the plan, providing the lender confidence that there's market demand for the completed product and that you'll have exit funding to repay the construction facility.

For a six-unit development in Nundah, a lender might require 50% pre-sold before providing unconditional approval. That means you need signed, unconditional contracts on three units with deposits held in trust before construction finance is released. These contracts need to be genuine arm's length transactions, not agreements with family or related parties. Pre-sale requirements vary by lender and project scale, with some accepting one or two pre-sales for smaller developments, while others require none if you can demonstrate capacity to hold the completed units long-term.

If you're planning to retain all units as rental properties rather than selling, pre-sales aren't relevant, but the lender will instead assess your ability to service debt across all units simultaneously. Rental appraisals for each proposed unit become part of the borrowing capacity assessment, with lenders typically shading rental income to 80% when calculating serviceability.

Preparing Your Construction Loan Application

A complete construction loan application for a multi-unit development site includes council-approved plans, a fixed price building contract from a registered builder, an itemised cost breakdown, proof of deposit funds, and financial statements if you're applying as a company or trust structure. Lenders also require a registered valuation on both the land in its current state and the proposed end value once all units are complete.

In our experience with Brisbane-based buyers, incomplete applications delay approval by weeks. The valuation process alone takes 10 to 15 business days, and if the valuer's assessment comes in below your purchase price or expected end value, the loan amount may be reduced or the application declined. Ordering the valuation after your development application is approved but before signing a contract gives you time to renegotiate or walk away if the numbers don't support your plans.

Your builder's credentials matter more in multi-unit projects than in single dwelling construction. Lenders want to see a Queensland Building and Construction Commission licence, evidence of completed projects of similar scale, and adequate insurance. If your builder is new to multi-unit work or recently licensed, expect additional scrutiny or requests for bank guarantees to protect against builder default.
