How does a construction loan work?

A construction loan is built for a home that does not exist yet, whether that is a new build, a house and land package, or a knockdown rebuild. Instead of releasing the full amount at settlement, the lender pays it out in stages as your build hits each milestone, and you only pay interest on what has been drawn. We compare construction loans across 35+ lenders and structure it the right way, at $0 cost to you.

Most lenders need a fixed-price contract with a licensed builder, and release the funds in stages against that contract, with a check at key stages of the build. That staged structure is not just process, it is one of your best protections if a build runs into trouble, because your money stays tied to the build rather than sitting with the builder. Once your home is finished, the loan converts to a normal mortgage.

Building can also open doors that buying established does not, from the First Home Owner Grant to a more tax-friendly position for investors after the 2026 changes. We cover all of it below.

How do progress payments work?

A construction loan releases funds in stages as your build hits each milestone, in line with your fixed-price contract and with a lender check at key stages. You only pay interest on what has been drawn. Here is a typical drawdown schedule.

StageWhat happensTypical share of the build
DepositPaid to your builder to start~5%
BaseSlab and footings laid~15%
FrameWalls and roof frame up~20%
LockupWindows, doors, and roof on~20%
FixingInternal fit-out and cabinetry~25%
CompletionFinishes and handover~15%

Illustration only, the exact stages and shares vary by lender and builder. Funds are released stage by stage against your fixed-price contract, with a lender check or valuation at key stages such as the base and completion, and you pay interest only on what has been drawn.

Protecting yourself from builder problems

Builder insolvency has been one of the biggest risks in building lately, with thousands of construction firms across Australia collapsing in the past year. If a builder goes under mid-project, you can be left with a half-finished home and the cost of getting someone else to complete it. It is worth taking seriously before you sign.

The good news is that a well-structured construction loan helps protect you. Because the loan is released in stages against your fixed-price contract rather than all at once, your money stays tied to the build instead of sitting with the builder, and lenders check progress before releasing funds, often with an inspection or valuation at key stages like the base and completion. On top of that, in NSW most residential building work must carry Home Building Compensation cover, which can help if your builder cannot finish or fix defects.

Before you commit, it pays to check the builder’s licence and insurance certificate, ask for recent references you can actually call, and be wary of a fixed price well below everyone else, which was a warning sign in several recent collapses. We help you set the loan and the checks up so your money stays tied to real progress.

What can you build with a construction loan?

A new home

Build from scratch on your own block, funded in stages.

House and land

Land finance and the build, lined up together from the start.

Knockdown rebuild

Build new on the block you already know and love.

Major renovation

For structural work that changes the footprint of the house.

Owner-builder

Possible, but harder to finance. We will be straight with you.

Investment build

A new build can suit investors better after 2026.

New builds, grants, and the 2026 tax changes

Building can unlock help that buying established does not. In NSW, the $10,000 First Home Owner Grant is for new homes only, so a new build or a house and land package can qualify, and new builds can also fit the low-deposit schemes. If it is your first home, our first home buyer page walks through what you can stack.

For investors, the 2026 budget made new builds stand out. From 1 July 2027, negative gearing against your salary ends for established homes bought after 12 May 2026, but new builds stay exempt and keep that benefit. Capital gains tax is also changing from 1 July 2027, with the 50% discount being replaced, and the treatment of new builds can differ, so the CGT side is worth confirming with your accountant. See our investment page for the full picture.

The short version: building can be more tax-friendly than buying established, especially for investors, but the rules are still settling. Everything here is general information, so check your own situation with your accountant.

Construction loan questions

Real answers to the questions people ask us about building and construction finance.

What is a construction loan?
A construction loan is a home loan built for a property that does not exist yet, like a new build, a house and land package, or a knockdown rebuild. Instead of releasing the full amount upfront, the lender pays it out in stages as your build reaches each milestone. Once the home is finished, it converts to a normal home loan.
Do I pay interest on the whole loan during the build?
No, only on the amount that has been drawn down at each stage. Early in the build your repayments are small because little has been released, and they rise as more is drawn. Most construction loans are interest only during the build, which keeps your holding costs down while you may also be paying rent.
How much deposit do I need for a construction loan?
Similar to a standard home loan, usually around 20% to avoid LMI, though some lenders will go higher with insurance. If you already own the land, its value counts toward your contribution, and if you have equity in another property you may be able to use that. We work out your position.
Can I use my equity to build or do a knockdown rebuild?
Yes, and it is common. If you own your home or another property, the equity can fund much or all of the build. For a knockdown rebuild you often already hold significant equity in the block, which can do a lot of the heavy lifting. See our using equity page.
How long do I have to build?
Lenders usually want construction to start within a set period, often around 12 months of the loan, and to finish within a set window after that. Delays happen, so we build in some room and keep you across the timeline. Long hold-ups can affect the loan, so it pays to plan realistically.
What is a contingency, and how much should I allow?
A contingency is a buffer on top of your base build cost for the unexpected, like site issues found during demolition or minor variations. A common allowance is around 10% to 15% of the build. With a fixed-price contract many overruns sit with the builder, but a buffer keeps you comfortable. We factor it into your numbers.
What are the costs of a construction loan?
Beyond the deposit, expect the usual loan setup fees plus a progress inspection fee at each drawdown, often a few hundred dollars per stage. Factor in demolition for a rebuild, and the cost of renting elsewhere during the build. We map the full picture so nothing catches you out.
What are the risks of a construction loan?
The main ones are builder problems or insolvency, cost overruns from variations, and delays that stretch out your interest-only period. Good structure manages all three: a fixed-price contract, a solid builder, a contingency buffer, and drawdowns released in step with the build. We set it up to keep you protected.
Should I use a mortgage broker for a construction loan?
It helps, because construction lending is more complex than a standard loan and not every lender does it well. We compare 35+ lenders, check your building contract, structure your progress payments to protect you, and manage the drawdowns through to completion. It costs you nothing, since the lender pays us on settlement.
