Construction Loan Preparation: What to Have Ready

Preparing for a construction loan application takes more work than a standard home loan.

You're not just proving you can repay the loan amount. You're showing lenders that your build is ready to proceed, your costings are realistic, and your builder is credible. In our experience, clients who get their documentation sorted before applying typically move from submission to settlement in about half the time of those who scramble to find paperwork after the fact.

Council Approval Comes First

Your development application needs council approval before most lenders will formally assess your construction loan application. This includes approved plans, engineering reports if required, and confirmation that your proposed build meets local regulations. In Narrabundah, where blocks often have established trees and heritage overlay considerations, council approval can take longer than anticipated. Clients sometimes assume they can apply for finance while waiting on council, but lenders won't commit until they see that approval in writing. Start this process months before you plan to apply for funding.

Fixed Price Building Contracts Lock In Your Budget

Lenders require a fixed price building contract from a registered builder before they'll approve construction funding. This contract needs to detail exactly what's being built, the total cost, and the progress payment schedule. A cost plus contract where expenses are invoiced as they occur won't satisfy most lenders because they can't assess your borrowing capacity without a firm figure. Consider someone building a four-bedroom home in Narrabundah with a $650,000 construction budget. Their lender will review that fixed price contract line by line, checking that all major works are included and that the payment structure aligns with building stages. If the contract excludes items like landscaping or fencing that the borrower assumes are included, the actual costs could blow out by $40,000 or more, which affects whether they can complete the build.

Progress Payment Schedules Need to Match Draw Schedules

Your builder's progress payment schedule determines when you need funds released, and lenders have their own construction draw schedule that governs when they'll release money. These two documents need to align closely. Most lenders use a five or six stage drawdown tied to specific milestones such as base stage, frame stage, lockup, fixing, and completion. Your builder might want payment at different intervals. Before applying, sit down with your builder and make sure their payment expectations match what your lender will approve. A mismatch here causes real problems because builders expect payment when they hit a milestone, but if your lender hasn't released those funds yet, you're stuck covering the gap from your own savings.

Land and Construction Packages Require Separate Valuations

If you're pursuing a land and build loan where you're purchasing suitable land and constructing simultaneously, lenders will value both components. They'll assess the land at current market value and the proposed construction based on your fixed price building contract. The combined valuation needs to support your total loan amount. In Narrabundah, where established blocks within walking distance of Narrabundah shops and schools typically value higher than blocks further out, you might find the land component makes up a larger portion of your total project cost than in newer suburbs. Lenders will only charge interest on the amount drawn down, which means you pay interest on the land purchase immediately but construction costs only attract interest as each stage is funded.

Documentation Your Lender Will Request

Beyond council plans and your building contract, prepare recent payslips, tax returns if you're self-employed, bank statements showing your deposit savings, and quotes for any work not covered in your building contract. Lenders also want proof of building insurance and your builder's warranty insurance. If you're acting as an owner builder, expect much closer scrutiny of your experience, subcontractor quotes, and project management capability. Owner builder finance applications take longer to assess because lenders see them as higher risk. Have detailed quotes from plumbers, electricians, and other subcontractors ready, along with evidence of your relevant building experience.

Interest-Only Repayment Options During Construction

Most construction loans offer interest-only repayment options while the build is underway. You pay interest monthly on whatever amount has been drawn down so far, and once construction completes, the loan typically converts to a standard principal and interest home loan. Some lenders require you to commence building within a set period from the disclosure date, usually six to twelve months. If you don't start construction within that window, your approval may lapse and you'll need to reapply. This matters in Narrabundah where builder availability can push start dates out further than you'd like. Lock in your builder and confirm their start date before finalising your finance approval.

Progressive Drawing Fees Add to Your Costs

Lenders charge a progressive drawing fee each time they release funds during construction, typically between $250 and $400 per drawdown. Over five or six stages, those fees add up to $1,500 to $2,400. They also require a progress inspection before releasing funds at each stage, which means sending a valuer or inspector to confirm the work is complete. These costs aren't usually included in your building contract, so factor them into your overall budget. Some borrowers also make additional payments during construction to reduce the interest they're paying as each stage is funded, which can save thousands over the construction period.

If you're looking at refinancing to fund a renovation instead of a full construction project, the documentation requirements are lighter but you'll still need detailed quotes and council approval if the work is structural.
