Buying a House in Western Australia: The Step-by-Step Process
Buying a house in Western Australia is structurally different from buying in any other Australian state. The contract is different, the professionals involved are different, the legal protections are different, and the government assistance programs are WA-specific. If you are relying on advice from friends in Sydney or Melbourne — or national property media — you are likely operating on wrong assumptions.
Here is how the process actually works, step by step.
Step 1: Work Out Your Realistic Budget
Before you look at a single property, you need to know exactly how much you can spend — including all the costs that are not the purchase price.
In WA, the main upfront costs beyond the deposit are:
- Transfer duty (stamp duty): First home buyers pay zero on established homes up to $600,000 (from May 2026), with a sliding scale above that. New builds and vacant land have separate thresholds.
- Settlement agent fees: Typically $800 to $1,500 in professional fees, plus disbursements of $400 to $600.
- Landgate lodgement fees: Approximately $443 for a standard residential lot.
- Building and pest inspection: $600 to $900 for both combined.
- Mortgage registration fees: Modest, but typically included in your settlement agent's disbursements.
If you are buying a new build, add to this the $10,000 First Home Owner Grant (which offsets costs for builds up to $800,000). If you are buying an established home under $500,000, you may be eligible for a $2,000 reimbursement under the Home Buyers Assistance Account (HBAA).
Most WA first home buyers also need to choose between the state's Keystart loan (2% deposit, no LMI, higher interest rate) and the federal First Home Guarantee scheme (5% deposit, no LMI, commercial bank rates). That choice depends on your income and how much cash you have saved.
Step 2: Get Finance Pre-Approval
Apply for conditional pre-approval from your chosen lender before you start making offers. Pre-approval tells you how much the lender is prepared to lend under current conditions — it is not a guarantee, but it is the basis for your budget ceiling.
For Keystart, apply directly through their portal. For the federal First Home Guarantee, apply through a participating mainstream lender.
Pre-approval typically takes one to two weeks for straightforward applications. Keep a recent payslip, bank statements, identification, and your credit history records ready.
Step 3: Understand the WA Contract: Offer and Acceptance
WA residential property is almost universally transacted through the REIWA Contract for Sale of Land or Strata Title by Offer and Acceptance — universally referred to as the O&A.
The O&A captures:
- The purchase price
- The deposit amount and when it is paid
- The settlement date
- Any special conditions (finance, building inspection, pest inspection)
- The property details
The O&A is read alongside the Joint Form of General Conditions for the Sale of Land, which governs the legal mechanics of encumbrances, default, and contract termination.
When you sign an O&A and submit it to the seller's agent, it is a formal offer. If the seller accepts in writing, the contract immediately crystallises into a legally binding agreement.

The No Cooling-Off Period Warning
This is the most important legal fact about buying in WA: there is no statutory cooling-off period.
In NSW and Victoria, buyers typically have 3 to 5 business days after signing to withdraw from a private treaty contract with minimal financial penalty. In Western Australia, that protection does not exist. Once the seller communicates acceptance of your written offer, you are bound.
Walking away exposes you to:
- Forfeiture of your deposit
- Potential legal action for damages
- In extreme cases, a court order forcing you to complete the purchase
This means every piece of due diligence — financial, legal, physical — must happen before you sign the O&A, not after. In a competitive market, this creates real pressure to move quickly. But signing before you are certain is genuinely dangerous in WA in a way it is not in most other states.
Step 4: The Finance Condition
The O&A almost always includes a "Subject to Finance" condition. This gives the buyer a specified period (typically 14 to 21 days) to obtain formal loan approval.
The critical trap: the O&A requires you to name the specific lender. If you leave the field blank or write "any financial institution," you are legally bound to accept finance from any institution that offers it — regardless of the terms. Buyers who have done this and then declined an offer from a high-rate lender have been held to be in breach of contract.
Name your specific lender in the O&A. If that exact lender formally declines your application, you can terminate the contract without penalty.
Step 5: The Building and Pest Inspection Conditions
Including a building inspection condition in your O&A is strongly recommended. The standard REIWA building inspection clause protects you against Major Structural Defects only.
What this means in practice:
- Minor defects — leaking showers, deteriorating gutters, non-structural damp — are not grounds for termination
- Freestanding sheds, detached carports, and retaining walls not supporting the main structure are typically excluded
- If a major structural defect is identified, the seller has the primary right to fix it — you cannot automatically walk away
- You can only terminate if the seller explicitly refuses to fix or negotiate on the defect
A pest inspection (timber pest, termite) is a separate condition. Perth's coastal sandy conditions are conducive to subterranean termite activity. In older suburbs with established trees and timber elements, this inspection is essential. Expect to pay $300 to $600 for a combined building and pest inspection.
Step 6: Settlement (28 to 42 Days)
Once all conditions in the O&A are satisfied — finance approved, inspections cleared — the contract becomes unconditional. Settlement typically occurs 28 to 42 days from that point.
During the settlement period, your settlement agent:
- Verifies the title search through Landgate
- Prepares transfer documents
- Coordinates with your bank on mortgage drawdown
- Calculates rate and water adjustments
- Processes settlement through PEXA
On settlement day, funds are transferred electronically via PEXA. The moment settlement completes, the title is simultaneously updated at Landgate with you as the registered proprietor.
After settlement, your settlement agent will arrange the handover of keys.
Key Differences from Eastern States Buying
If you have absorbed national property advice and are buying in WA for the first time:
| Western Australia | NSW / VIC | |
|---|---|---|
| Cooling-off period | None | 3 to 5 business days (private treaty) |
| Conveyancing professional | Settlement Agent (non-lawyer) | Solicitor or conveyancer |
| Electronic settlement | Mandatory (PEXA) | Standard but not universal |
| Standard contract | REIWA O&A | State-specific contracts |
| Title system | Landgate (Torrens) | Land registries |
| FHOG | New builds only | Varies by state |
Getting the Process Right
The WA buying process rewards preparation. Buyers who have their finance pre-approval confirmed, have chosen a settlement agent, understand their stamp duty position, and have researched the specific suburbs they are targeting can act confidently when the right property appears.
The Western Australia First Home Buyer Guide at /au/western-australia/first-home/ walks through every stage in detail — including a complete O&A clause-by-clause explanation, a due diligence checklist to complete before signing, a timeline from offer to settlement keys, and worked cost examples at four different price points so you know your exact cash requirement at each stage.
