Proven Tips to Meet Building Finance Regulations

Building finance regulations exist to protect both you and the lender during construction, but they add layers of paperwork and timing requirements that differ completely from standard home loans.

The regulations cover three main areas: the type of building contract you use, how council approval is handled, and when funds are released during construction. Each of these affects how quickly you can start building and what flexibility you have if plans change.

Why Lenders Require a Fixed Price Building Contract

Most construction lenders will only approve finance if you have a fixed price building contract with a registered builder. This means the total cost is agreed upfront and cannot increase unless you make changes to the original plan.

The alternative is a cost-plus contract, where you pay the builder's costs plus a margin. This structure creates uncertainty for lenders because the final loan amount is not locked in. In our experience, fewer than 10% of construction lenders will consider cost-plus arrangements, and those that do typically require a larger deposit or charge higher rates.

Consider a primary teacher planning to build in regional New South Wales. They found a builder willing to work on a cost-plus basis, which offered more flexibility to adjust materials during construction. However, when they applied for finance, only one lender would proceed, and that lender required a 30% deposit instead of the standard 10%. They returned to the builder, negotiated a fixed price contract instead, and secured approval with a 10% deposit at a lower rate within three weeks.

Council Approval Must Be In Place Before Settlement

You need development application approval from your local council before most lenders will settle a construction loan. This is not the same as having plans drawn. The council must have formally approved the plans and issued a development consent.

The approval process typically takes 6 to 12 weeks depending on the council and complexity of the build. Some councils require additional reports for bushfire-prone land, flood zones, or heritage areas, which can extend the timeline. If you are building in an area with specific environmental overlays, factor in extra time.

Once council approval is granted, most lenders require you to commence building within a set period from the disclosure date, usually 12 months. If construction has not started within that window, the loan approval may lapse and you will need to reapply. This can be a problem if your builder is booked out or if you are waiting on other approvals.

How the Progressive Drawdown System Works

Construction loans operate differently to standard home loans. Instead of receiving the full loan amount upfront, funds are released in stages as building progresses. Lenders only charge interest on the amount drawn down, not the total approved loan.

The drawdown schedule is tied to construction milestones, typically slab down, frame up, lock-up, fixing, and practical completion. At each stage, the lender arranges a progress inspection to confirm the work has been completed before releasing the next payment. The builder or your solicitor will request each drawdown, and the lender pays the builder directly.

Most lenders charge a progressive drawing fee for each inspection and payment, usually between $200 and $400 per drawdown. With five or six payments over the build, these fees add up to $1,000 to $2,400. Some lenders cap the number of fee-free drawdowns and charge for additional inspections if your builder requests more frequent payments.

Interest-Only Repayments During Construction

During the construction period, most borrowers make interest-only repayments on the amount drawn down so far. You are not required to pay principal until the build is complete and the loan converts to a standard home loan.

This keeps repayments lower while you may still be paying rent or a mortgage on your current property. Once construction is finished and the loan converts, you switch to principal and interest repayments based on the full loan amount.

Some lenders offer a construction to permanent loan, which means the construction loan automatically converts to a standard home loan once the build is complete. You do not need to reapply or go through a second approval process. This structure is more common now and removes uncertainty about whether you will be approved for the permanent loan after construction.

Owner Builder Finance Is Harder to Obtain

If you plan to act as an owner builder rather than hiring a registered builder, expect far fewer finance options. Most mainstream lenders will not provide owner builder finance because the risk of construction delays or cost overruns is higher without a licensed builder managing the project.

The lenders that do offer owner builder finance typically require a 20% to 30% deposit, detailed project plans, and evidence that you have construction experience or qualified tradespeople lined up for each stage. You will also need to manage all progress payments to subcontractors, plumbers, and electricians yourself, and coordinate inspections with the lender.

For a primary teacher without a background in construction, this level of project management is often not realistic alongside a full-time teaching role. Unless you have prior building experience or a strong reason to avoid using a registered builder, a fixed price building contract with a licensed builder will open up far more finance options.

Land and Construction Package vs Separate Purchase

You can finance land and construction together in a single loan or purchase the land first and apply for construction finance later. A land and construction package combines both into one approval, which means you only go through the application process once.

The benefit of a combined package is that you lock in the loan structure and rate for both the land purchase and the build upfront. The downside is that if construction is delayed or you change your mind about the build, you are paying interest on the land while it sits vacant.

If you purchase the land separately and apply for construction finance later, you have more time to finalise plans and choose a builder. However, you will need to meet lending criteria twice, and if your financial situation changes between the land purchase and the construction application, you may not be approved for the build.

What Happens If Construction Runs Over Time

Most construction loans are approved with an expected completion date, usually 6 to 12 months from the start of construction. If the build runs over that timeframe due to weather, material shortages, or builder delays, the lender may extend the construction period but will continue charging interest on the drawn-down amount.

Some lenders will allow an extension without reassessing your financial position, while others may require updated income and expense documentation to confirm you can still afford the loan. If your circumstances have changed, such as moving to part-time work or taking parental leave during the build, this reassessment can create complications.

Before committing to a builder, ask for a realistic completion timeline and check whether the lender has a maximum construction period. If your builder quotes six months but the project is complex or materials are hard to source, build in a buffer rather than assuming everything will go to plan.
