Avoid These 5 Mistakes with Multi-Unit Construction Loans

Multi-unit construction projects move through different funding stages than single dwelling builds. Lenders assess development applications differently, draw schedules become more complex, and the wrong loan structure can lock up capital when you need it most.

Applying Without Development Approval Already in Place

Most lenders require full development approval and council plans before they will issue formal loan approval for multi-unit construction. Conditional approval means little if the development application is still being assessed or requires modifications. Consider a scenario where a developer in Logan applies for construction finance while the DA is still under review. The lender provides conditional approval based on the submitted plans, but council requests changes to car parking and setbacks. When the revised plans are submitted to the lender, the project no longer meets loan-to-value ratio requirements because the reduced floor area lowers the end valuation. The developer now needs to find additional equity or scale back the project. Securing development approval before lodging your construction loan application removes this risk and gives lenders the certainty they need to commit funding.

Using a Cost Plus Contract Instead of a Fixed Price Building Contract

Lenders prefer fixed price building contracts for multi-unit developments because they cap the funding requirement and reduce completion risk. A cost plus contract leaves the final build cost uncertain, which means the lender cannot confidently assess whether the approved loan amount will be sufficient. In our experience, projects using cost plus arrangements often face funding shortfalls mid-construction when material costs rise or additional trades are required. Most construction lenders will either decline the application outright or offer reduced loan-to-value ratios if the contract is not fixed price. If your registered builder is proposing a cost plus arrangement, expect to provide a larger deposit or seek alternative funding for cost overruns.

Underestimating How Progress Payment Schedules Affect Cash Flow

Multi-unit developments typically follow a progressive drawdown structure where the lender releases funds at set milestones such as slab down, frame up, lockup, and practical completion. You only pay interest on the amount drawn down, which helps manage holding costs during construction. However, the builder's progress payment schedule may not align perfectly with the lender's draw schedule. If your builder requires payment before the lender releases the next drawdown, you need to cover that gap from your own funds. As an example, a duplex project in Ipswich reached lockup stage and the builder invoiced for the next progress payment. The lender's valuer scheduled the inspection for the following week, and funds were released three days after that. The developer needed to cover the payment from savings for ten days to keep the builder on schedule. Understanding both schedules before construction starts allows you to plan for these timing gaps and avoid disputes with your builder.

Overlooking the Progressive Drawing Fee on Each Drawdown

Each time the lender releases funds during construction, they charge a progressive drawing fee to cover the cost of the valuer's site inspection and administration. This fee typically ranges from $300 to $600 per drawdown depending on the lender and the project size. For a multi-unit development with six to eight drawdown stages, these fees add up to several thousand dollars across the build. Budget for these costs separately from your construction contract and interest holding costs. If your loan amount is already at the maximum loan-to-value ratio the lender will accept, you cannot simply add these fees to the loan. They must be paid from your own funds at each stage. Failing to account for progressive drawing fees is one of the most common reasons developers run short on liquidity mid-project.

Starting Construction Before Loan Funds Are Fully Committed

Some developers commence building within a set period from the disclosure date to meet builder contract terms, assuming the lender will release funds as scheduled. If the lender identifies an issue during their final due diligence or the valuation comes in lower than expected, funding can be delayed or reduced. A developer in Caboolture began earthworks on a triplex development after receiving conditional loan approval. During final valuation, the valuer noted that comparable sales in the area had softened and revised the end valuation down by 8%. The lender reduced the approved loan amount accordingly, leaving a $70,000 funding gap. The developer had already committed to the builder and had to source additional equity from a family member to proceed. Construction finance is not confirmed until the loan contract is signed and all conditions are satisfied. Do not authorise progress payments or allow site works to begin until funds are unconditionally approved and available for drawdown.

How Multi-Unit Construction Differs from Single Dwelling Finance

Multi-unit projects require more detailed documentation than single home builds. Lenders assess not only the quality of construction but also the end-value of each unit and the demand in the local market. They often require evidence that the registered builder has completed similar projects and holds adequate insurance. Interest-only repayment options are common during the construction phase, allowing you to manage holding costs without principal repayments. Once construction reaches practical completion, most lenders will convert the construction loan to a standard investment or commercial loan structure depending on whether you plan to hold or sell the units. Knowing how your lender structures the transition from construction funding to permanent finance prevents surprises when the build is complete and you need to refinance or settle individual unit sales.

Multi-unit construction finance moves through stages that require coordination between your builder, lender, and council. Timing gaps, fee structures, and contract types can all affect whether your project stays on budget. Call one of our team or book an appointment at a time that works for you to discuss how your development application and build contract align with lender requirements.
