Construction Loans: The Features and How They Work

What Makes Construction Loans Different from Standard Home Loans

You only pay interest on what's been drawn down, not the full loan amount upfront. A standard home loan releases the full amount at settlement, but construction loans release funds in stages as your build progresses. Each time the builder completes a stage and the lender's valuer confirms the work, another portion of the approved amount gets released.

This staged approach means your interest charges start small and increase gradually. Consider a scenario where you've been approved for a $450,000 construction loan in Tarneit. After the initial slab stage, you might have drawn $90,000. You're only paying interest on that $90,000 until the next stage, not the full loan amount. By frame stage, you might be at $200,000 drawn, and your interest adjusts accordingly. The total loan isn't fully drawn until practical completion, which could be six to nine months after you start building.

Progressive Drawdown and the Payment Schedule

Most lenders work with a five-stage progress payment schedule that aligns with standard building milestones. The typical stages are base or slab, frame, lock-up, fixing, and practical completion. Your builder submits a progress claim after completing each stage, the lender arranges a progress inspection to verify the work, and then releases the next payment directly to the builder.

The exact split varies between lenders, but a common structure might be 10% at base, 20% at frame, 35% at lock-up, 25% at fixing, and 10% at completion. Some lenders charge a Progressive Drawing Fee each time they release funds, which typically ranges from $200 to $400 per drawdown. Over five stages, that's an additional $1,000 to $2,000 on top of your standard loan costs.

If you're building on land you already own in one of Tarneit's newer estates like Reflections or Riverdale Village, the land value often forms part of your total security. That equity can reduce how much you need to borrow for the actual construction, though you'll still need to budget for the progressive fee structure.

Interest-Only Repayment Options During Construction

Most construction loans automatically operate on interest-only repayments during the building phase. You're not required to pay down the principal while construction is underway, which keeps your repayments lower when you're potentially still paying rent or another mortgage elsewhere. Once the build reaches practical completion and the loan converts to a standard home loan, you can choose whether to continue with interest-only or switch to principal and interest repayments.

That interest-only period during construction helps with cash flow, but you need to plan for the jump in repayments once the loan converts. If your interest-only repayment on a partially drawn loan is $1,200 per month, it might increase to $2,800 per month once the full amount is drawn and you switch to principal and interest. Some borrowers in Tarneit who are building while renting use the construction period to save extra funds so they're prepared for the higher ongoing repayment.

How Fixed Price Contracts Affect Loan Approval

Lenders require a fixed price building contract before they'll approve a construction loan. A cost plus contract, where the final price can vary based on actual costs, creates too much uncertainty for most lenders to assess the loan properly. Your contract needs to specify the total build cost, inclusions, and payment stages, and it must be signed with a registered builder who holds appropriate insurance.

If your builder quotes $380,000 for the build and you've allowed $15,000 for additional items like landscaping or window treatments, your lender will want to see that the total project cost is within your approved loan amount plus any cash contribution you're making. They'll also check that the progress payment schedule in your building contract aligns with their drawdown stages. If there's a mismatch, the broker can work with both parties to adjust the payment terms before settlement.

Land and Construction Packages Versus Buying Land Separately

A land and build loan can cover both the land purchase and the construction in one approval, or you might buy land first and apply for construction finance later. If you're purchasing a house and land package from a developer in Tarneit, the land component usually settles first, and construction begins afterward. You'll need to commence building within a set period from the date you settle on the land, often six to twelve months, depending on the lender.

If you buy land now but don't plan to build for a year or more, some lenders won't approve the construction portion until you're closer to starting. Others will approve the full package upfront but require you to start within their specified timeframe. That timeframe matters in Tarneit's newer estates where some blocks come with developer building requirements or estate covenants that dictate construction start dates.

Progress Inspections and Why Timing Matters

Every time your builder requests a progress payment, the lender arranges a progress inspection before releasing funds. A qualified valuer or building inspector visits the site, checks that the stage has been completed to the standard outlined in the contract, and confirms the work matches the claim amount. The lender won't release funds until that inspection is signed off.

Delays in inspections can slow down your build. If your builder finishes the frame stage but the inspection takes a week to arrange and another few days for the lender to process, your builder might be waiting on funds before they can pay sub-contractors like plumbers or electricians and move to the next stage. Most lenders process inspections within a few business days, but it's worth understanding the timing when your builder is coordinating tradespeople and material deliveries.

Council Approval and Development Application Requirements

Your lender will want proof that all council plans and approvals are in place before they'll formally approve your construction loan. That includes your building permit and any other development application requirements specific to your block. In Tarneit, some estates have additional design guidelines or planning overlays that can affect approval timing, especially for blocks near wetlands or within particular precincts.

If your block requires an amended site plan or additional drainage work to meet council requirements, those approvals need to be finalised before the lender will release funds. Submitting your loan application before your approvals are locked in can lead to delays or conditions you weren't expecting, so most brokers recommend having your council approval sorted before starting the finance process.

When Owner Builder Finance Works Differently

If you're planning to act as an owner builder rather than using a registered builder, far fewer lenders will consider your application. Owner builder finance is treated as higher risk because there's no builder's warranty insurance and no registered builder overseeing quality construction. The lenders who do offer it typically require a larger deposit, charge a higher interest rate, and have stricter conditions around the progress payment schedule.

You'll also need to provide detailed cost breakdowns for materials and labour, and some lenders will only release funds after each stage is inspected and signed off by an independent building consultant they appoint. If you're considering owner builder in Tarneit, expect the approval process to take longer and the documentation requirements to be significantly more involved than a standard construction loan with a registered builder.

Renovation Finance Versus New Construction Loans

A house renovation loan operates on similar principles to new home construction finance, but lenders often cap the loan amount at a lower level and have tighter criteria around the scope of work. If you're doing a knock-down rebuild in an established part of Tarneit, that's usually treated as new construction. If you're renovating an existing home, lenders will assess the value of the property before and after the renovation, and the loan amount is based on that increased value.

Renovation finance also tends to have fewer formal stages than a new build. Instead of five fixed drawdowns, you might have three or four payments tied to demolition, structural work, and completion. Some lenders allow the borrower to manage the funds themselves rather than releasing directly to a builder, but only if the renovation is relatively minor and the borrower has strong financial history.
