Construction & Building Loans in Perth
Building a new home or knocking down and rebuilding on your Perth block runs on a different loan structure to a standard mortgage. Instead of one lump sum, a construction loan pays out in stages as your builder hits agreed milestones: slab, frame, lock-up, fixing, and completion. You only pay interest on the amount drawn down at each stage, not the full loan amount from day one, which keeps repayments lower while the build is underway. Getting this set up correctly matters more than most people expect, because a poorly structured loan can leave you short at a progress payment or stuck negotiating with a lender mid-build.
We've listed 128 mortgage brokers across Perth who handle construction and building finance. Not all of them work with every lender or every type of build (owner-builder, knock-down-rebuild, or a display-home package through a volume builder), so it pays to check their experience with your specific project type before committing.
Our scoring looks at how each broker communicates, how accurately they scope the loan against the build contract, and how they've handled the practical friction points: valuation shortfalls, variations, and delayed drawdowns. For a shortlist of the top-rated options, see our ranked guide to Perth mortgage brokers, and read our methodology for how we weigh and verify each score.

Common questions about construction & building loans
- How much does a construction loan cost compared to a standard home loan?
- Rates are often slightly higher than a standard owner-occupier loan, and most lenders charge a progress inspection fee for each drawdown (roughly $150-$300 per inspection). You'll also pay any standard application and valuation fees, plus interest-only repayments during the build phase before it converts to principal and interest.
- How often do people need a construction loan in Perth?
- Anyone building a new house, doing a knock-down-rebuild, or taking on major structural renovations will typically need one, rather than a standard purchase mortgage. It's a one-off product for the build period, then it usually rolls into a normal home loan once the certificate of occupancy is issued.
- What should I expect during the loan process?
- Expect the lender to release funds in stages tied to your builder's progress claims, with a valuer or inspector confirming each stage is complete before payment. You'll need a fixed-price building contract, council-approved plans, and often proof of your own funds (deposit or land equity) upfront.
- How do I judge whether a broker is good at construction loans specifically?
- Ask how many construction loans they've settled in the last year and which lenders they use most for staged drawdowns, since not all lenders handle this well. A broker who asks detailed questions about your building contract and variation clauses before recommending a lender is usually more reliable than one who treats it like a standard purchase loan.
