Construction loans in Perth fuel a thriving dream: building your own home tailored exactly to your needs.
But what are these loans, exactly?
Here’s a full cheatsheet covering everything you need to know about construction loans Perth.
Some are short-term loans that cover each stage of your build.
Some are structured with progress payments, aligned with your builder’s schedule.
Some come with risks like delays, cost overruns, and fluctuating interest rates.
Some lenders are specialists focused on the local WA market, offering tailored advice and compliance guidance.
Some borrowers find them complex without local expertise and miss out on key benefits and pitfalls.
Let’s dive right in.
What Are Construction Loans in Perth?
A construction loan finances the building of a new home, rather than buying an existing property. In Perth, these loans are typically short-term, covering the stages of construction through progress payments. Once the home is complete, the loan usually converts into a regular mortgage or is refinanced.
Unlike a standard home loan, you don’t receive the full loan amount upfront—funds are released in stages as your builder meets agreed milestones. This means you only pay interest on the amount drawn down, not the total loan.
The building process can be complex, so lenders often require a fixed-price contract with a licensed builder and a detailed construction schedule to approve the loan.
This approach helps both you and the lender manage risks and ensures payments align with the work completed.
Construction loans in Perth are also known as build loans or construction home loans.

How Do Construction Loans Work in WA?
The structure of these loans is designed to suit the progression of building a home. Here’s a simplified overview:
- Pre-Approval: You’ll first get pre-approval based on your finance, income, and credit situation.
- Loan Approval & Contract: Once you have a signed building contract and site plans, you formally apply for the construction loan.
- Progress Draws: The lender releases money in parts, known as progress draws, at milestones like slab completion, framing, roofing, and finishing.
- Interest Payments: During construction, you typically pay interest only on the amounts drawn so far, reducing carrying costs.
- Completion: When the build is finished and a final inspection conducted, your loan can convert into a standard home loan or be refinanced.
This process ensures funds are used directly and sequentially towards construction phases, providing security for both the lender and borrower.
Most lenders require your builder to be licensed and registered, and you’ll usually need a detailed progress payment schedule designed to match bank payments.
Keep in mind that delays during construction can affect the loan’s timeline and payments. For example, Perth’s recent challenges with land Title delays have extended building start times, which lenders factor into financial planning.
Expert mortgage specialists familiar with construction loans in Perth including suburbs like Rockingham and Wellard can help navigate these complexities.
Key Timelines and Stages of a Construction Loan
Understanding the typical timeline helps you plan finances and expectations effectively.
The entire construction loan journey can take 9 to 18 months or longer depending on your project size, builder efficiency, and local council approvals.
Here’s the general breakdown:
- Pre-approval & Loan Setup: 4-8 weeks — Including finance assessment, contract review, and deposit preparation.
- Construction Period: 6-12 months — Progress payments released as milestones are met: slab, frame, lock-up, fixing, finishing.
- Loan Conversion: 1-2 weeks — Once construction is certified complete, the lender converts your construction loan into a regular home loan or refinances it.
Note that delays in council permits, land titles, or unexpected site issues can add weeks or months, influencing interest costs and cash flow.
Some lenders allow a buffer period to accommodate such delays, but it’s vital to discuss this in advance with your lending adviser or mortgage broker.
Risks to Consider With Construction Loans
Construction loans offer great flexibility but come with inherent risks that every borrower should understand:
- Cost Overruns: If building costs exceed the contract price due to changes or supply issues, you may need additional funds not covered by your loan agreement.
- Delays in Construction: Weather, supplier shortages, or permit issues can delay progress, increasing interest costs and repayment stress.
- Interest Rate Fluctuations: Many construction loans have variable rates; rising interest rates during your build increase repayments.
- Builder Risk: If your builder encounters financial difficulties, it might disrupt the project, potentially affecting loan drawdowns.
- Valuation Variations: Lenders base loan amounts on land plus building contract value, using recent comparable sales. Market fluctuations can affect borrowing power.
Mitigating these risks involves proper planning, fixed-price contracts, lender communication, experienced brokers, and selecting reputable builders.
For detailed advice on navigating risks, consider consulting specialised construction finance brokers in local suburbs such as Baldivis or Rockingham.
Important Tips for Applying Construction Loans in Perth
Tip: Work with a mortgage specialist experienced in construction loans who understands WA policies and local market conditions to avoid costly mistakes.
Here’s a checklist to boost your chances of securing a construction loan and avoiding delays:
- Get pre-approved before signing a building contract.
- Use a licensed builder registered with the Housing Industry Association (HIA).
- Ensure your building contract has fixed pricing and includes a clear progress payment schedule.
- Prepare detailed plans and documentation including site and building permits.
- Maintain good communication with your lender; submit progress claims promptly to avoid payment delays.
- Have contingency funds set aside for unexpected costs or delays.
These steps can not only smooth the loan process but also help keep your construction on track financially and on time.
How to Budget for Your Construction Loan
Budgeting carefully is essential to avoid cash flow issues mid-build. Here are some expert pointers:
- Include All Costs: Beyond the build price, factor in land acquisition costs, council fees, site works, and professional fees like architects or engineers.
- Contingency Fund: Allocate approximately 10-15% of your building budget for unexpected expenses.
- Interest Payments: Construction loans typically have interest-only payments during the build, but these add to ongoing costs.
- Living Expenses: If renting during construction, include rental payments plus interest repayments in budgeting.
- Progress Payment Scheduling: Understand the timing and amount of progress draws so you can plan personal finances accordingly.
Consultation with a home loan broker Perth can provide tailored budget plans aligned with your loan and market conditions.

Keystart Finance, funded by the WA Government, targets first home buyers and those entering the housing market with low deposits.

Some key points include:
- Loan limits have recently been raised to $730,000 to align with Perth’s median house price, making it more accessible for construction loans.
- Interest rates may be slightly higher compared to commercial banks, reflecting the higher risk undertaken.
- Keystart requires a fixed price contract and progress payment schedule similar to standard loans.

Common Mistakes to Avoid With Construction Loans
Understanding the pitfalls that catch many borrowers in Perth can save you time and money.
- Ignoring the Need for Pre-Approval: Starting your build without loan pre-approval can lead to funding shortfalls and contract issues.
- Choosing Unlicensed Builders or Verbal Contracts: Lenders require formal, fixed-price contracts with licensed builders.
- Missing Progress Claim Deadlines or Documentation: Late or incomplete progress payment requests can delay drawdowns, stalling construction.
- Underestimating Interest Costs During Build: Interest payments accumulate during construction; failing to budget for these increases financial pressure.
- Not Considering Market Value Changes: Borrowing based on estimated future value rather than current land plus contract value can result in valuation gaps.
- Inadequate Contingency Planning: Not setting aside funds for unexpected expenses often causes build halts or poor-quality work compromises.
Being proactive with planning and working closely with a lending adviser is the best defence against these common issues.
Do you know how to prepare your building contract to align with your construction loan? It’s often overlooked but critical.
Special Considerations for First Home Buyers
First home buyers in Perth can access specific supports and loan programs designed to ease entry into property ownership.
Construction loans can be paired with these incentives, such as the First Home Owner Grant and Keystart Finance schemes, to reduce upfront costs.
Additionally, government initiatives sometimes offer stamp duty concessions or grants specifically for newly built homes, which coupled with appropriate loans, can significantly reduce financial hurdles.
However, first home buyers should be particularly attentive to the risks of construction loans, budgeting carefully for rent and repayments during build periods and working closely with trusted mortgage specialists.

The WA property market, including construction finance, is influenced by several factors:
