Smart ways to finance a new investment build

Building an investment property from the ground up gives you control over layout, finish, and rental appeal that you can't replicate with an established home.

The difference between building your own home and building an investment property comes down to cash flow during construction. You're funding a project that won't produce rental income until it's finished, and most lenders apply a different risk assessment when the property isn't your primary residence. Your construction loan needs to be structured so that interest during the build phase doesn't erode your deposit, and so that the transition to a standard investment loan happens without a second full application.

Consider an investor buying a vacant block in Ringwood North near Proclamation Park with a fixed price building contract for a four-bedroom dual-level home. The land settles at the current median, the build cost sits around $450,000, and the total project comes in under $1.8 million. The buyer has a 25% deposit across the combined land and build cost. The lender approves a construction facility with progressive drawdown, meaning the bank releases funds in stages as the build reaches milestones like slab pour, frame up, lockup, and practical completion. Interest is charged only on the amount drawn down at each stage, not on the full loan amount. During construction, the borrower makes interest-only payments on whatever has been drawn to date. Once the build is complete and the occupancy permit is issued, the loan converts to a standard investment loan with interest-only repayment options for a set term, and the property is tenanted.

How the Progress Payment Schedule Aligns with Lender Drawdown

Your builder invoices you at defined stages, and your lender releases funds after each stage is inspected and signed off.

Most fixed price building contracts in Victoria follow a schedule tied to the Domestic Building Contract, which sets out the timing and percentage of the contract price payable at each stage. Typical progress payments include a deposit on signing, a payment at slab stage, frame stage, lockup stage, fixing stage, and a final payment at practical completion. The lender's construction draw schedule runs parallel to this, but the bank won't release funds until its valuer or building consultant confirms the stage is complete. The gap between when your builder expects payment and when the bank releases the drawdown is where timing issues surface. Most lenders allow a small buffer, but if your builder moves faster than the inspection schedule allows, you may need to cover a payment from your own funds temporarily until the bank catches up.

In Ringwood North, where sloping blocks are common around the Mullum Mullum Valley, slab costs can run higher than budget if the site requires significant cut and fill. If your builder invoices for slab completion but the lender's valuer hasn't signed off, you either wait for approval or pay the builder directly and claim reimbursement once the drawdown is released. Your broker manages this process by confirming the inspection turnaround time with the lender upfront and flagging any risk of delay to you before the build starts.

What Lenders Assess Differently for Investment Construction

Lenders treat construction finance for an investment property as higher risk than construction finance for an owner-occupied home, and the approval criteria reflect that.

Your borrowing capacity is assessed on the projected rental income once the property is complete, not on the current state of the block. The lender will order a valuation that includes an 'as if complete' figure, which estimates the property's market value once the build is finished. That figure determines your loan-to-value ratio. Most lenders cap investment construction loans at 80% LVR without lenders mortgage insurance, and some won't offer LMI on investment construction at all, effectively making 80% the ceiling. Serviceability is tested against the interest rate during construction, which is typically variable and higher than the rate you'd pay on an established investment loan. Some lenders also apply a rental income discount during the assessment, assuming the property won't be tenanted immediately after completion.

The build must commence within a set period from the loan approval date, usually six months, and must reach practical completion within 12 months from the first drawdown. If the build is delayed beyond that window, the lender may require a revaluation or a fresh approval. Your income, employment stability, and existing debt position are assessed more conservatively than they would be for a standard home loan, particularly if you're holding other investment debt or if this build will take you above two financed properties.

Council Approval and the Fixed Price Building Contract

Your lender won't approve the construction facility until council plans are stamped and a registered builder has signed a fixed price building contract.

The development application must be approved by the City of Maroondah, and the building permit must be issued before the bank will proceed to formal approval. Ringwood North sits within a mix of Neighbourhood Residential and General Residential zones, and any new build needs to meet ResCode requirements around setbacks, overshadowing, and site coverage. If your block backs onto the Ringwood North Reserve or Proclamation Park, the council may apply additional overlays affecting building height or vegetation removal. These conditions need to be cleared before the permit is issued.

The building contract must be with a registered builder holding current domestic building insurance, and the contract must be a fixed price contract, not a cost plus contract. Lenders won't fund construction on a cost-plus basis for residential builds because the final cost is undefined, which makes the end valuation and LVR unreliable. The fixed price contract sets the total build cost, and the lender uses that figure to structure the total loan amount and the progress payment schedule. Any variations to the contract during the build need to be approved by the lender in writing before the additional cost is drawn down, otherwise you're funding the variation from your own cash.

Interest Capitalisation and Cash Flow During the Build

Most lenders allow you to capitalise interest during construction, meaning the interest charged each month is added to the loan balance rather than paid in cash.

This keeps your out-of-pocket costs lower while the property isn't generating income, but it increases the total debt you're carrying when the loan converts to principal and interest or interest-only repayments after completion. If you capitalise interest on a 12-month build with an average drawn balance of $900,000 and a variable rate sitting above 6%, you're adding roughly $54,000 to the loan by the time the build finishes. That amount is rolled into the final loan balance, which affects your LVR at conversion and your ongoing repayment amount.

Some investors prefer to make interest-only payments in cash during construction to avoid increasing the debt, particularly if they're close to the 80% LVR threshold and don't want capitalised interest to push them over. Your broker will model both scenarios before you commit so you can see the trade-off between preserving cash now and carrying higher debt later. The same analysis applies if you're holding an existing property that you plan to sell after this build is complete, as the timing of that sale relative to the construction phase determines whether you're servicing two loans simultaneously.

The Valuation, the Progressive Drawing Fee, and the Conversion to Investment Loan

The lender orders two valuations: one at approval to confirm the 'as if complete' value, and one at practical completion to confirm the finished property meets that valuation before converting the loan.

The first valuation is desktop or kerbside in some cases, particularly if the suburb has strong comparable sales data and the build is a standard design. The second valuation is a full inspection once the occupancy permit is issued. If the completed property values below the 'as if complete' figure used at approval, your LVR increases and the lender may require you to reduce the loan balance to meet the agreed LVR, either by paying down the difference in cash or by accepting a higher interest rate to reflect the increased risk.

Each drawdown attracts a progressive drawing fee, typically between $300 and $500 per draw depending on the lender. With five or six draws across a standard build, that's an additional $2,000 to $3,000 in fees on top of the application and settlement costs. Some lenders charge a construction management fee upfront instead of per-draw fees, so the total cost is known at the start. Your broker compares the fee structures across lenders during the application stage, particularly if you're weighing up a lender offering a lower interest rate but higher draw fees against one with a higher rate and a flat construction fee.

Once the build reaches practical completion, the loan converts from a construction facility to a standard investment loan. That conversion is not automatic. The lender requires the occupancy permit, the final valuation, proof that all progress payments have been made, and confirmation that the property is insured as a completed dwelling. If any of those documents are missing, the conversion is delayed and you remain on the construction loan rate, which is typically higher than the investment loan rate you were expecting.
