For many first home buyers, a house and land package is about finding the right balance: a price you can manage, a floorplan you actually like, and a growing area with new facilities on the way. That’s why places like Wilton, Appin and the wider south west growth corridor are on the radar for couples planning their first build.

Construction Loans for First Home Buyers

One of the most common questions we hear is this:

“While we’re building and still renting, what do our repayments look like?”

A construction loan is designed for this exact scenario. Instead of giving you the full loan amount upfront, the lender releases funds in stages as the home is built. Your repayments generally start lower and rise gradually throughout construction.

Below is a clear guide to how construction loans work, what to expect at each stage, and how to set yourself up for a smoother build.

What is a construction loan?

A construction loan is a home loan used to fund a build. The key difference from a standard home loan is progress payments.

Rather than drawing the full loan at once, the lender pays the builder in stages as the work is completed. During construction, repayments are usually interest-only and calculated on the amount drawn so far, not the total approved loan amount.

This helps you manage risk and aligns payments with real progress on your building site.

How construction loans work with house and land packages

Most house and land packages involve two contracts:

Land contract (to purchase the block)
Building contract (to construct the home)

In many cases, the loan is structured so that:

you settle on the land first, then
construction funding begins once building is ready to commence (based on the building contract, plans, and approvals)

Because the land and build components can occur at different times, it’s important that your loan is structured for the expected timeline, especially if land registration or approvals take longer than anticipated.

The progress payment stages (how the builder gets paid)

Most lenders follow a similar construction payment schedule. Stages can vary slightly by builder, but commonly include:

Slab / Base stage
Frame stage
Lock-up stage
Fixing stage (internal fit-out such as plaster, cabinets, tiling)
Completion

At each stage:

the builder issues a progress claim (invoice)
the lender reviews the documentation and may confirm the stage has been completed
the lender pays the builder directly

This means payments match the build, rather than being paid in one lump sum.

Repayments while you’re building and still renting

This is where a construction loan can feel more manageable for first-home builders.

While construction is underway, most lenders set repayments to interest-only on whatever has been drawn at that point. Because the loan is paid out in stages, your repayments tend to increase bit by bit as the build progresses. When construction is complete, the loan typically moves to a standard home loan and your repayments settle into their normal long-term level.

Why this matters when you’re building your first home

If you’re a first-home buyer building through a house and land package, the biggest pressure point is usually cash flow. Most couples are still renting while the home is being built, and they want to know what repayments will look like as the build progresses.

Things to consider before your commit

Before you commit to a house and land package, it’s worth doing a quick “reality check” on the numbers and the process. Build budgets can change once upgrades, variations, and unexpected site costs come into play, so having a buffer can save you from tough decisions later. It also helps to look closely at what the contract actually includes, because two packages that look similar online can be priced very differently once you factor in items like site works, driveways, fencing, landscaping and service connections.

On the bank side, remember the lender will assess the loan based on the expected value of the completed home, so if the valuation comes in lower than you anticipated it can affect how much you can borrow or what deposit you’ll need.

And finally, lender choice matters more with construction than it does with a standard purchase. Progress payments and construction policies vary, so working with a lender that handles construction loans smoothly can make the build process far less stressful.
