Construction Loan Features You'll Actually Use

Construction finance works differently to standard home loans because you're not borrowing the full amount upfront.

You're drawing down funds in stages as the build progresses, and the features that matter most are the ones that control when you access money, how much interest you pay, and what happens if your builder hits delays. If you're planning to build in Mayfield or anywhere across the Hunter region, knowing which features actually impact your cash flow makes the application process far more straightforward.

Progressive Drawdown Matches Your Build Timeline

With construction loans, funds release in instalments tied to specific milestones rather than a single upfront payment. You'll only pay interest on the amount drawn down to that point, not the total loan amount.

Consider someone building a custom home in Mayfield West, close to Hanbury Street. Their construction draw schedule might release funds at five or six stages: slab down, frame up, lock-up, fixing stage, and practical completion. At slab stage, they've drawn perhaps 20% of the total loan amount. Interest applies only to that 20% until the next drawdown occurs. This structure keeps borrowing costs lower during the build compared to taking the full loan amount from day one. Some lenders charge a Progressive Drawing Fee each time funds release, typically between $150 and $400 per draw. Others bundle this into the loan without separate fees.

The timing between drawdowns can stretch from a few weeks to several months depending on builder schedules and weather delays. Your lender arranges a progress inspection before releasing each payment, usually conducted by a quantity surveyor or building inspector who confirms the stage is complete.

Interest-Only Repayment Options During Construction

Most construction finance includes interest-only repayment options for the building period, switching to principal and interest once you move in. This keeps monthly commitments lower while you're potentially paying rent elsewhere and managing construction costs.

In our experience working with Mayfield clients, particularly those renovating older workers cottages near the former BHP sites, this feature matters when you're juggling existing housing costs during a six to nine month build. The interest-only period typically extends from first drawdown through to practical completion, then continues for another six to twelve months after you settle into the home. This gives you breathing room to adjust your budget before full repayments begin. Some lenders offer a construction to permanent loan structure that automatically converts to a standard variable or fixed rate home loan once the build finishes, avoiding a second application process.

Fixed Price Building Contract Requirements

Most lenders require a fixed price building contract with a registered builder before approving construction funding. This protects both you and the lender from cost blowouts.

The contract needs to specify the total build cost, a progress payment schedule aligned with construction stages, and completion timeframes. You'll typically need council approval and stamped plans before the application progresses. Cost plus contracts, where you pay actual costs plus a builder's margin, receive approval from fewer lenders and usually at higher interest rates due to the uncertainty around final costs. The fixed price building contract also determines your progress payment finance structure. If your contract shows six payment stages, your lender structures drawdowns to match. Any variations to the original contract during the build require lender approval before additional funds release, which can add time to your construction timeline if you decide to upgrade fixtures or change layouts mid-build.

Land and Construction Package Structuring

When you're buying suitable land and building simultaneously, a land and construction package combines both elements into one facility. You'll need enough deposit to cover both the land purchase and contribute toward construction costs.

As an example, someone purchasing a vacant block in Mayfield's industrial conversion zone near Maitland Road might pay $320,000 for land and budget $580,000 for construction. With a 10% deposit on the combined $900,000, they'd need $90,000 upfront. The lender settles the land purchase first, then holds the remaining construction funds for progressive drawdown. During land settlement through to build commencement, you're paying interest only on the land component. Once construction starts and drawdowns begin, interest compounds on both land and whatever construction funds have released. Some lenders require you to commence building within a set period from the disclosure date, typically six to twelve months after land settlement, or the loan terms may change.

Owner Builder Finance Considerations

Owner builder finance is available but typically requires a larger deposit and comes with tighter conditions. Lenders view owner builds as higher risk because you're coordinating trades directly rather than using a licensed builder with insurance and warranties.

You'll usually need to demonstrate building experience, provide detailed cost breakdowns for materials and subcontractors, and maintain builder's insurance throughout construction. The progress payment schedule becomes more granular because lenders want confirmation that funds go toward materials and paying subcontractors like plumbers and electricians rather than general expenses. Expect more frequent inspections and potentially higher interest rates compared to loans with registered builders. The approval process takes longer because lenders assess your capacity to manage the build, not just your capacity to service the debt.

If you're planning significant house renovation work in one of Mayfield's older Federation homes, working with a mortgage broker in Mayfield who understands which lenders still offer owner builder products saves time during the application stage. Many major banks have withdrawn from this space, leaving specialist lenders and a narrower range of options.

Additional Payment Flexibility

Some construction loan structures allow additional payments during the interest-only period without penalty, letting you reduce the principal even before standard repayments begin. This feature matters if you sell an existing property during your build or receive unexpected income.

The loan amount you can access depends on your borrowing capacity, just like any other mortgage, but construction finance also factors in the land value and expected property value on completion. Most lenders will lend up to 80% of the lower of these two figures without requiring lenders mortgage insurance. Building your borrowing capacity before you commit to land purchase gives you a realistic budget for both elements. Your construction loan application typically requires council plans, a copy of your building contract, soil test results, and engineering specifications in addition to standard income and asset documentation. Processing takes longer than a standard home loan because lenders verify both your financial position and the viability of your building project.
