What are Construction Loans for Multi-Unit Sites?

What Construction Finance Covers for Multi-Unit Development Sites

Construction finance for multi-unit development sites covers both the land purchase and the staged building costs, with funds released progressively as construction reaches predetermined milestones. Unlike a standard home purchase where the full loan settles at once, lenders release the loan amount in instalments aligned with a progress payment schedule.

Consider a developer purchasing a corner block in South Yarra zoned for multi-residential use. The site costs $2.8 million, and the builder quotes $3.6 million for a six-townhouse development under a fixed price building contract. The lender approves a total facility of $5.5 million based on the end value, but only disburses funds as each stage completes. At settlement, the developer receives enough to purchase the land. When foundations are laid and inspected, the next drawdown releases funds to pay the builder. This continues through frame stage, lock-up, fixing, and practical completion. The lender only charges interest on the amount drawn down at each stage, not the total approved facility.

The construction draw schedule typically includes five to seven stages, with each release conditional on a progress inspection by the lender's valuer or quantity surveyor. Developers need sufficient equity or cash flow to cover gaps between builder invoices and lender releases, particularly if the builder requires payment before the lender's inspection occurs.

Council Approval and Development Application Requirements

Lenders require an approved development application and all council plans finalised before they commit to construction funding. A conditional approval is not sufficient. The builder must be ready to commence building within a set period from the disclosure date, usually within six months, or the loan offer may lapse.

South Yarra sits within the City of Stonnington, which applies heritage overlays and design guidelines to much of the suburb, particularly around Chapel Street and Toorak Road. A development application for a multi-unit site often takes longer here than in outer suburbs due to resident objections and design review processes. In our experience, developers who engage a town planner early and factor in a 12 to 18 month approval timeline avoid the pressure of racing to satisfy lender deadlines. The lender will also review the development application to confirm the proposed end value aligns with their valuation and loan security.

Once council approval is secured, the lender requires a registered builder with appropriate insurance to sign the building contract. Owner builder finance is rarely available for multi-unit developments due to the complexity and risk involved.

Fixed Price Contracts Versus Cost Plus Structures

Most lenders prefer fixed price contracts for multi-unit developments because the total cost is defined upfront, reducing the risk of budget overruns. Under a fixed price building contract, the builder agrees to complete the project for a set sum, and the progress payments are staged as percentages of that total.

A cost plus contract, where the builder charges for actual costs plus a margin, introduces uncertainty that lenders view unfavourably. If costs escalate, the developer must either inject additional equity or risk the project stalling. Some lenders will consider cost plus arrangements for experienced developers with a proven history, but they typically require a larger deposit and cap the loan at a lower percentage of the total project cost.

Progressive Drawdown and How Interest Accrues

Progressive drawdown means funds are released in stages as construction progresses, and interest accrues only on the amount drawn down to date. During construction, most lenders offer interest-only repayment options, with the interest either paid monthly or capitalised into the loan balance.

In a scenario where a developer has drawn down $4 million of a $5.5 million facility, the construction loan interest rate applies only to the $4 million, not the full approved amount. At current variable rates, this structure reduces the holding cost during the build phase compared to drawing the full loan at settlement. However, capitalising interest increases the total debt, which affects the end loan-to-value ratio and may require a larger deposit to stay within the lender's limits.

Developers also need to budget for a progressive drawing fee, typically between $300 and $600 per drawdown, and the cost of progress inspections, which the lender arranges but charges to the borrower.

Settlement Costs and Equity Requirements

Lenders typically provide up to 70% to 75% of the total development cost for multi-unit projects, which includes both land and construction. The developer must contribute the remaining 25% to 30% as equity, which can come from cash, existing property equity, or a combination.

For developments in South Yarra, where land values are high and construction costs reflect inner-city labour and material rates, the equity requirement is substantial. The developer also needs to cover settlement costs such as stamp duty on the land purchase, legal fees, lender establishment fees, and valuation costs before construction begins. These upfront expenses sit outside the construction loan and must be funded separately.

If you're considering construction loans for a development site, the equity position determines not only whether the loan is approved but also the construction loan interest rate offered. Developers with equity above 30% often access lower rates and more flexible terms.

How the Progressive Payment Schedule Aligns with Builder Invoices

The progressive payment schedule in the building contract must align with the construction draw schedule set by the lender. Misalignment creates cash flow pressure, particularly if the builder requires payment before the lender releases the next instalment.

Builders working on multi-unit projects often include clauses requiring payment within 10 to 14 days of reaching each stage. The lender, however, needs time to arrange the progress inspection, receive the valuer's report, and process the drawdown. This lag can be two to three weeks. Developers who fail to plan for this gap may need to use their own funds temporarily or negotiate payment terms with the builder upfront.

In projects involving multiple trades such as plumbers and electricians, the builder typically pays sub-contractors from the progress payments received. If the developer is managing the build directly under an owner-occupied construction loan, the responsibility to pay sub-contractors falls on the borrower, and lenders scrutinise cash flow more closely.

Construction to Permanent Loan Structure

A construction to permanent loan transitions automatically from construction funding to a standard mortgage once the project reaches practical completion. The developer does not need to reapply or refinance, and the loan converts to principal and interest repayments unless an interest-only period is negotiated.

For multi-unit developments in South Yarra, many developers plan to sell some or all of the completed townhouses to repay the loan. If the intent is to retain the properties as investment loans, the lender will assess rental income during the application to ensure the borrower can service the debt once construction is complete. The exit strategy must be clear at the time of application, as it affects the lender's willingness to approve the facility and the rate they offer.

Developers who plan to occupy one unit and sell the others should disclose this upfront, as lenders classify part of the loan as owner-occupied and part as investment, which affects the loan structure and rate.

Choosing a Lender for Multi-Unit Development Finance

Not all lenders offer construction finance for multi-unit developments, and those that do have different appetites for risk, location, and borrower experience. Major banks typically require the developer to have completed at least one prior project, while smaller lenders and non-bank financiers may accept first-time developers if the equity position is strong and the project is well-documented.

South Yarra's established market and proximity to the CBD make it a location that lenders view favourably, but the high land cost means the loan size is substantial, which narrows the pool of willing lenders. Working with a broker who can access construction loan options from banks and lenders across Australia increases the likelihood of securing approval and a competitive rate.

Lenders also assess the end value of the development, not just the cost. If the valuer determines the completed townhouses will be worth less than the total development cost plus a margin, the loan is unlikely to proceed. The valuation is forward-looking and based on comparable sales, so recent transactions in South Yarra for similar multi-unit developments carry significant weight in the approval process.

Timelines and What Delays Cost

Construction loans have strict timelines. If building does not commence within the agreed period, the loan offer expires and the developer must reapply, which incurs additional costs and delays. If construction stalls midway, the lender may freeze further drawdowns until the issue is resolved, leaving the developer unable to pay the builder or sub-contractors.

Delays also increase holding costs. Each additional month of construction means another month of interest accruing on the drawn portion of the loan, and if the market shifts during that time, the end value may fall below the lender's original valuation, creating a shortfall at settlement.

Developers who build contingency into the timeline and budget, both for council approval delays and construction issues, are better positioned to absorb setbacks without jeopardising the project. A buffer of 10% to 15% on both cost and time is standard practice for experienced developers working in inner-city locations like South Yarra.
