Do you know how construction loans work for investment property?

Building an investment property from the ground up gives you control over the design, finish, and location. Construction finance is structured around a progressive drawdown, where the lender releases funds in stages as the build progresses, and you only pay interest on the amount drawn down at each stage.

This article covers how construction loans differ from standard investment loans, what lenders assess before approval, and how the drawdown process works in Queensland.

How construction loans differ from standard investment loans

A construction loan releases funds in instalments as your builder completes specific stages, rather than providing the full loan amount upfront. During construction, you typically make interest-only repayments based only on the amount drawn down so far. Once the build is complete and you receive a certificate of occupancy, the loan converts to a standard investment loan with principal and interest repayments.

Consider an investor purchasing suitable land for $280,000 and contracting a registered builder for $420,000 under a fixed price building contract. The lender approves a total loan amount of $630,000 at 90% of the combined land and construction cost. The land purchase settles first, drawing down $280,000. From that point, you pay interest only on that amount until the builder requests the first progress payment. As each stage completes and further funds are drawn, your interest repayments increase proportionally. This structure means your borrowing costs remain lower during the construction period compared to drawing the full amount upfront.

What lenders assess when approving construction finance

Lenders assess your borrowing capacity based on the full loan amount, even though you will not draw it down immediately. Your income, existing debts, and living expenses must support the eventual principal and interest repayments once construction is complete. Lenders also evaluate the builder's credentials, the building contract, and council approval before committing funds.

Most lenders require a fixed price contract with a registered builder who holds appropriate insurance. Owner builder finance is available but attracts stricter conditions and higher interest rates due to the increased risk. The development application and council plans must be finalised before the lender will issue formal approval. In Queensland, some lenders will also require that you commence building within a set period from the Disclosure Date, typically six to twelve months, to ensure the valuation remains current.

How the progressive drawdown works

The lender releases funds according to a progress payment schedule that aligns with the stages outlined in your building contract. Common stages include base stage, frame stage, lock-up stage, fixing stage, and practical completion. Before each payment, the lender arranges a progress inspection to verify that the work has been completed to the required standard. Once satisfied, the lender pays the builder directly or releases funds to you, depending on the contract structure.

You will typically pay a Progressive Drawing Fee for each inspection and drawdown, which ranges from $200 to $400 per stage depending on the lender. These fees cover the cost of the independent valuer or building inspector who confirms the stage is complete. The builder invoices you or the lender at each stage, and the funds must be released within a specified timeframe, usually five to ten business days after approval. Any delay in the inspection or approval process can hold up the builder's cash flow, so staying on top of the schedule is important.

Interest-only repayments during construction

During the construction phase, most lenders offer interest-only repayment options on the amount drawn down. This reduces your monthly outgoings while the property is not generating rental income. Once construction is complete and the property is tenanted, you can choose to continue with interest-only repayments or switch to principal and interest, depending on your investment strategy and cash flow.

The construction loan interest rate is typically slightly higher than a standard investment loan rate, reflecting the additional administration and risk involved in progressive funding. Variable rates are more common, though some lenders offer fixed rate options for the construction period. Once the loan converts to a standard investment loan, you can refinance to a different product or lender if a lower rate is available.

Land and construction packages versus purchasing land separately

Some developers offer land and construction packages where the land and building contract are sold together, often as part of a house and land package in a new estate. These packages can streamline the approval process because the lender receives a complete proposal with a registered builder already attached. However, purchasing land separately and selecting your own builder gives you more control over the design and choice of contractor.

In Queensland, land and build loans for investment purposes are common in growth corridors north and south of Brisbane, where new estates are releasing titled lots. Lenders generally prefer titled land over land that is still subject to subdivision or registration. If the land is not yet titled, the lender may issue conditional approval but will not settle the land component until the title is registered. This can delay the start of construction, so confirming the title status before committing to a purchase is important.

What happens if construction costs exceed the contract price

If the builder requests additional payments beyond the fixed price building contract, the lender is not obligated to fund the increase. Cost overruns due to variations, delays, or disputes are your responsibility unless the contract includes a cost plus arrangement. Under a cost plus contract, the builder invoices you for actual costs plus a margin, rather than a fixed total. Lenders are generally reluctant to fund cost plus contracts for investment properties due to the uncertainty around the final loan amount.

In our experience, investors who budget a 5% to 10% contingency on top of the contract price are better positioned to manage unexpected costs without derailing the build. This contingency should be held in accessible savings rather than relied upon as additional borrowing, as lenders will not increase the loan amount mid-construction without a formal reassessment of your borrowing capacity and a new valuation.

Converting to a standard investment loan after completion

Once the build is complete and you receive a certificate of occupancy, the lender will arrange a final inspection and valuation. The construction loan then converts to a standard investment loan, and your repayments adjust to reflect the full loan amount on either an interest-only or principal and interest basis. At this point, you can also arrange a loan health check to confirm your rate remains appropriate and explore whether refinancing or restructuring would improve your cash flow.

If the completed property value exceeds the combined land and construction cost, you may have additional equity available. This can be used to fund further investment purchases or reduce your loan-to-value ratio, which may qualify you for a lower interest rate. However, relying on capital growth during construction is not guaranteed, particularly in markets where supply is increasing due to new estates or higher density development.

Building an investment property involves coordination between your builder, lender, and solicitor, with each stage requiring approval before funds are released. Structuring the loan correctly from the start, understanding the progress payment schedule, and maintaining a cash buffer for contingencies will help the project run to plan.
