Top Strategies to Choose Construction Loan Features

You only pay interest on what's been drawn down, not the full loan amount from day one.

That's the fundamental difference between construction loans and standard home loans, and it changes how you budget for the build. When you're building in Long Jetty, where blocks near The Entrance Road or around Tuggerah Lake attract buyers wanting to custom design rather than settle for existing stock, understanding how your lender releases funds and charges interest makes a tangible difference to what you'll spend during the build phase.

Progressive Drawdown and How Interest Accrues

Most lenders release construction funding in stages tied to your progress payment schedule, typically five or six draws across the build. You'll pay interest only on the amount released so far, which keeps your repayments lower during construction. If your lender has advanced $150,000 for slab and frame, you're charged interest on that amount, not the full approved loan. Once the next stage is inspected and approved, the lender releases more funds and your interest calculation adjusts.

Some lenders charge a Progressive Drawing Fee each time they inspect and release funds, usually between $200 and $400 per draw. Others bundle this into the interest rate or waive it entirely. The fee structure matters more than it sounds because six inspections can add $1,200 to $2,400 to your build costs. When you're working with a fixed price building contract, these fees sit outside the contract and need separate cash flow planning.

Fixed Price Contracts vs Cost Plus Arrangements

A fixed price building contract locks in the build cost upfront, which makes it simpler to match your loan amount to your project. Your builder quotes a total figure, your lender approves funding based on that contract, and the progress payments follow a set schedule. Most lenders prefer fixed price contracts because the risk is contained and the progress inspection process is straightforward.

Cost plus contracts are less common in residential builds but come up when you're doing something non-standard or acting as an owner builder. The builder charges for actual costs plus a margin, which means the final price isn't confirmed until the build is complete. Lenders treat these as higher risk, so you'll often need a larger deposit and face stricter approval criteria. If you're considering owner builder finance, expect lenders to ask for detailed costings, proof of builder experience, and higher equity.

Interest-Only Repayments During the Build

Most construction loans default to interest-only repayments during the build phase, switching to principal and interest once construction is complete and you convert to a standard home loan. This keeps your cash flow manageable while you're still paying rent or covering other housing costs.

Consider someone building a four-bedroom home on a 600-square-metre block near Long Jetty Public School. They've sold their previous property and are renting month-to-month while the build progresses. The lender has approved a land and construction package, with the land settled and the first drawdown covering initial site costs and slab. During the six-month build, they're paying interest only on the progressive amounts drawn, which starts at a few hundred dollars per month and increases as more funds are released. Once the build is complete and the occupancy certificate is issued, the loan converts to principal and interest repayments, and they move in.

Some lenders allow you to make additional payments during construction if you want to reduce the principal early, though most buyers prefer to keep cash available in case of build delays or cost variations.

Timeframes and When You Must Commence Building

Lenders typically require you to commence building within a set period from the loan settlement date, usually six to twelve months. If you don't start within that window, the lender may reassess the loan or withdraw approval. This becomes relevant when council approval takes longer than expected or when your registered builder's schedule pushes your start date out.

In Long Jetty, where development applications for new builds around the lake foreshore can involve additional environmental or flood considerations, the approval timeline isn't always predictable. If your DA is still with council three months after loan approval, talk to your lender about extending the commencement deadline rather than assuming it will roll over automatically.

Land and Construction Packages vs Separate Land Purchase

If you're buying land and building in one transaction, a land and construction package rolls both into a single loan. The lender settles the land first, then releases construction funds progressively as the build advances. This is common for house and land packages in newer estates around Woongarrah or Wadalba, but it works equally well for standalone blocks in Long Jetty if you've secured suitable land and have council plans ready to go.

If you already own the land or bought it separately, you'll need a construction-only loan. The lender uses your existing equity in the land as part of your deposit, so if you own a block outright, you may not need additional cash savings to meet the deposit requirement. Equity in land is treated the same way as cash when the lender calculates your loan-to-value ratio.

Lender Inspections and Releasing Funds to Your Builder

Your lender will arrange a progress inspection before releasing each drawdown. The inspector confirms that the stage described in the progress payment schedule has been completed to the required standard, then approves the release. This protects you and the lender from paying for work that hasn't been done.

Some builders expect payment upfront for the next stage, but most lenders won't release funds until after the inspection. If your builder is pushing for payment before the stage is complete, that's a red flag. The progress payment schedule in your building contract should align with your lender's drawdown process, and your builder should be familiar with how construction funding works.

If there's a dispute about whether a stage is complete or up to standard, the lender won't release the funds until it's resolved. In that scenario, you're caught between the builder demanding payment and the lender withholding it. Having a registered builder with a solid reputation reduces this risk significantly.

What Happens If the Build Goes Over Budget

If your builder identifies cost variations partway through, you'll need to cover the difference from your own funds unless you can increase your loan amount. Lenders won't automatically extend your construction funding just because the build is costing more than expected. They approved the loan based on your original contract and your borrowing capacity at the time.

In our experience, build cost variations come up most often around site works, retaining walls, or upgraded finishes that weren't in the original spec. If you're building on sloping land near the lake or dealing with high water tables, expect site preparation costs to be higher than a flat block inland. Talk to your builder and your lender before signing anything so you know where the cost risks sit and who wears them if things change.
