Top Strategies to Prepare Your Construction Loan Documents

Your construction loan application is only as strong as the paperwork behind it. If your contract, plans and approvals line up before you apply, your lender has fewer reasons to pause.

That is good news, because most of this is within your control. If you are planning to build in Mount Lawley or rebuild on an existing block, a little preparation now can save you weeks of back and forth later. Here is what lenders look at and how to get ahead of it.

What Documents Do You Need for a Construction Loan Application?

A construction loan application needs your personal financial details plus a full set of building documents. The building side usually includes a signed building contract, council-approved plans, a building permit and your builder's details.

The personal side looks much like a regular home loan. Lenders want to see your income, savings, debts and living expenses, so it helps to understand your borrowing capacity before you sign anything with a builder. The building side is what surprises people, because the lender is lending against a home that does not exist yet. They need to be confident it can be finished, and that it will be worth what you are borrowing against once it is.

Requirements differ between lenders. A broker can check which paperwork suits your chosen lender before you lodge, which avoids sending documents twice. You can read more about how construction loans work on our main page.

Fixed Price Building Contract: What Your Lender Requires

Most lenders require a fixed price building contract, because it sets out the total cost and the stages of the build. A clear contract makes it easier for a lender to work out your loan amount.

Lenders generally want the contract to be signed, complete and consistent with your plans and specifications. If the plans show one thing and the specification says another, expect questions. Check that any allowances for items like landscaping or driveways are clearly written, and ask your builder to explain anything that reads as an estimate rather than a firm price.

Your builder matters too. A lender will usually want to know your builder is a registered builder with the right licence and insurance in place. Ask for these details early, because a builder who is slow to provide them can hold up your whole application.

How a Construction Draw Schedule Works

A construction draw schedule is the list of stages at which your lender releases money to your builder. Each release is called a progress payment, and you only pay interest on the amount drawn so far.

The schedule normally follows the stages in your contract, such as slab, frame, lockup, fixing and completion. Before each payment, the lender will usually want an invoice from the builder and often a progress inspection to confirm the work is done.

As an example, consider a couple building a new home on a block they already own. Their contract has stages, and after the slab stage the lender has released a total of $200,000. At the illustrative rate of 6.75% p.a., interest-only repayments on that drawn balance come to about $13,500 a year, or around $1,125 a month. They are not charged interest on the money still waiting to be drawn. As the frame and later stages are paid, the drawn balance and the monthly interest rise. By completion, they know the interest payments have grown in step with the build, and they have planned for this in their budget.

The trade-off is that interest-only repayments do not reduce the loan. Once construction ends, the loan usually moves to principal and interest repayments, which are higher. Delays can also stretch the build and the period you may be paying rent or a mortgage on your current home at the same time. Some lenders also charge a fee each time they release a payment, so ask about that upfront.

Council Approval and Plans: Sort These Before You Apply

Council approval and a building permit need to be in place, or close to it, before most lenders will approve the loan for construction. Lenders want proof the build is allowed to go ahead.

In practice, your builder or designer usually handles the application to your local council. Your part is to keep copies of the approved plans and any conditions attached, and to make sure the plans you give your lender match the ones in your contract. Even small differences, like a changed floor layout, can trigger a request for updated documents.

Timing is worth thinking about too. Lenders often set a window for when building must start after approval, so check the dates on your approvals and talk to your broker if your start date is slipping.

Owner Builder or Cost Plus Contract? Expect More Questions

Owner builder finance and cost plus contracts both carry more uncertainty for a lender, so expect more paperwork and a closer look at your plans. Not every lender offers these options, and the ones that do often apply stricter rules.

With a cost plus contract, the final price is not locked in. Instead you pay the builder's actual costs plus an agreed margin. Lenders tend to want detailed cost estimates and sometimes a larger buffer, because the total could change. With owner builder finance, you manage the build yourself and pay the plumbers, electricians and other sub-contractors directly. Lenders may want evidence of your building experience, a detailed budget and the relevant permits.

The main risk is cost. If the build runs over budget, you carry that extra cost yourself, and your lender may not lend more. If you are weighing up these options, talk to a broker before you commit to a contract, since the structure you choose can limit which lenders will consider you. We can also look at how the build fits with your wider home loan needs.
