Do You Know How Multi-Unit Development Finance Works?

How Construction Finance Differs for Multi-Unit Projects

Construction finance for multi-unit developments operates on a progressive drawdown basis, where the lender releases funds in stages as specific milestones are completed and verified through progress inspections. Unlike standard home loans, you only pay interest on the amount drawn down at each stage, which reduces holding costs during the build phase.

Consider a developer constructing three townhouses on a consolidated block in Eight Mile Plains. The project requires $900,000 in construction funding under a fixed price building contract. Rather than receiving the full loan amount upfront, the developer accesses funds across six stages: base stage at 15%, frame stage at 25%, lock-up at 35%, fixing stage at 20%, practical completion at 3%, and final completion at 2%. At the base stage, only $135,000 is drawn down, meaning interest charges apply to that amount rather than the full $900,000. This structure allows the developer to manage interest costs while maintaining sufficient cash flow to pay sub-contractors according to the progress payment schedule.

The lender typically charges a Progressive Drawing Fee at each inspection point, usually between $300 and $500 per drawdown. These fees cover the cost of independent valuers who verify that work has been completed to the standard required before releasing the next payment. For a six-stage development, budget approximately $2,500 in progressive drawing fees across the construction period.

Council Approval Requirements Before Loan Approval

Lenders require full development application approval from Brisbane City Council before finalising construction loan applications for multi-unit projects. The approval must be current, unconditional, and specifically cover the scope of work outlined in your building contract.

Eight Mile Plains falls within Brisbane City Council jurisdiction, and multi-unit developments in this area typically face assessment periods of 40 to 60 business days for code-assessable applications. If your development requires impact assessment due to height, density, or site constraints, allow three to six months for the approval process. Lenders will not issue formal loan approval or lock in construction loan interest rates until council approval is unconditional, which means timing your finance application to align with your development approval stage prevents unnecessary delays.

Once council plans are approved, your registered builder can finalise the fixed price building contract. The contract must specify the total build cost, the progress payment schedule aligned to construction stages, and the timeframe for practical completion. Most lenders require you to commence building within a set period from the Disclosure Date, typically six to twelve months, to ensure the loan terms and project costings remain valid.

How the Progressive Payment Schedule Protects Cash Flow

The progress payment schedule written into your building contract determines when funds are released and how much is drawn at each stage. For multi-unit developments, lenders typically structure six to eight drawdown points tied to physical milestones rather than time-based intervals.

In a scenario involving four townhouses under construction near the Gateway Motorway precinct, the developer worked with a registered builder who proposed a seven-stage payment schedule. The schedule allocated 10% at slab stage, 20% at frame, 15% at roof and wall cladding, 20% at lock-up, 20% at fixing stage, 10% at practical completion, and 5% at final completion. The lender required progress inspections by an independent valuer before releasing each payment. At the lock-up stage, the valuer confirmed that external walls, windows, and roof were complete before authorising the drawdown. This structure ensured the builder had sufficient funds to pay sub-contractors including plumbers and electricians, while the developer only paid interest on funds actually deployed into the project.

The progressive drawdown approach reduces interest costs during construction and provides a built-in quality control mechanism. If a stage inspection identifies incomplete work or defects, the lender will withhold that drawdown until the issues are rectified, giving you leverage to ensure quality construction standards are maintained throughout the build.

Fixed Price Contracts vs Cost Plus Structures

Most lenders providing construction finance for multi-unit developments require a fixed price building contract with a registered builder. This contract type specifies a total build cost that cannot increase unless you authorise variations in writing, which provides certainty for both you and the lender.

A cost plus contract, where the builder charges actual costs plus a margin, is rarely accepted by mainstream lenders for multi-unit projects due to the financial risk of cost overruns. Owner builder finance is available for multi-unit developments, but only a limited number of specialist lenders offer it, and the interest rate is typically 0.5% to 1% higher than standard construction funding. If you are managing the build directly, expect stricter conditions around progress payment finance, including larger cash deposit requirements and more frequent progress inspections.

Fixed price contracts protect you from unexpected cost increases during construction. If material prices rise or labour costs escalate after the contract is signed, the builder absorbs those costs rather than passing them to you. In return, you must follow the agreed progress payment schedule and avoid making variations that delay the build or increase costs outside the contract scope.

Interest-Only Repayment Options During Construction

Construction loans typically offer interest-only repayment options during the build phase, meaning you only pay interest on the drawn-down balance without reducing the principal. Once construction reaches practical completion, the loan converts to a standard principal and interest structure unless you specifically arrange ongoing interest-only terms.

For multi-unit developments intended as investment properties, interest-only terms during construction reduce monthly outgoings while rental income is not yet available. If you plan to sell one or more units upon completion, the interest-only structure preserves cash flow during the construction period when holding costs are highest. Once units are completed and either tenanted or sold, you can reassess the repayment structure based on your investment strategy.

Some lenders allow additional payments during the construction phase without penalty, which can reduce the total loan amount before the principal and interest repayments commence. If your development budget includes contingency funds that remain unspent, applying those funds to reduce the loan balance before conversion can lower your ongoing repayment obligations.

How Land and Construction Packages Work for Development Sites

If you are purchasing suitable land specifically for a multi-unit development, a land and construction package allows you to finance both the land acquisition and the build under a single loan structure. The lender assesses the combined project, including land cost, construction budget, and the expected end value of the completed units.

For development sites in Eight Mile Plains, lenders typically require a deposit of 20% to 30% of the total project cost, which includes both land and construction. If the land is purchased for $500,000 and the build cost is $900,000, the total project cost is $1,400,000, requiring a cash contribution of $280,000 to $420,000. The lender will also assess whether the end value of the completed units supports the total loan amount, usually requiring the combined sale value to exceed the project cost by at least 20%.

Land and build loan structures release funds for the land purchase at settlement, then hold construction funds in reserve until building commences. Once the slab is poured and the first progress inspection is completed, construction drawdowns commence according to the agreed schedule. This structure prevents you from needing separate land and construction loans, which reduces application costs and simplifies the approval process.

What Lenders Assess for Multi-Unit Construction Loans

Lenders assess your capacity to service the loan during both the construction phase and after completion. During construction, they calculate serviceability based on interest-only repayments on the full loan amount, even though you will only be charged interest on the drawn-down balance. After completion, they assess principal and interest repayments based on your intended use of the units, whether you plan to hold them as rentals, sell them, or occupy one yourself.

Your development application, fixed price building contract, and progress payment schedule are reviewed to ensure the project is viable and that the builder is appropriately licensed and insured. Lenders also require evidence that you have sufficient cash reserves to cover cost overruns, typically 10% to 15% of the total construction budget. If your project budget is $900,000, you will need access to an additional $90,000 to $135,000 in contingency funds beyond your deposit and settlement costs.

If you are working with a mortgage broker experienced in construction finance, they can structure your application to highlight project viability and connect you with lenders who actively fund multi-unit developments in the Eight Mile Plains area. Different lenders have different risk appetites for development projects, and matching your application to the right lender increases approval likelihood and may improve the interest rate offered.
