How to Make an Offer on a House in WA With Confidence
Learn how to make an offer on a house in WA, from price research and finance to special conditions, deposits, counteroffers and acceptance.
To make an offer on a house in WA, complete and sign a written Offer and Acceptance contract with the proposed price, deposit, settlement date, finance position and special conditions. The seller may accept, reject or counter the offer. Once acceptance is communicated, the contract can bind both parties. Western Australia has no mandatory cooling-off period for real estate contracts, according to the WA Consumer Protection Commissioner.
The safest offer is not always the highest one. It is the offer whose price, finance position, dates and special conditions match what the buyer can actually complete. This guide covers the decisions to make before signing, the details to record, and the steps that follow a counteroffer or acceptance.
What should you do before making an offer in WA?
Complete the work that determines both your price limit and your contract terms before emotion takes over. A practical pre-offer file should include:

- recent comparable sales for genuinely similar properties
- lender guidance or finance pre-approval where borrowing is required
- an estimate of transfer duty, settlement costs and immediate repairs
- the title and any available strata information
- questions about approvals, easements, fixtures and known defects
- a shortlist of building, timber pest and other inspections
- independent advice on any contract condition you do not understand
Comparable sales should match the property type, land component, accommodation, condition and location as closely as possible. A renovated character home in Subiaco and an unrenovated property nearby may attract the same search filters but require different price reasoning.
The Perth western suburbs buying guide provides a broader framework for suburb and property research before the offer stage.
What documents form a WA property offer?
A standard private-treaty offer commonly uses two documents:
- the Contract for Sale of Land or Strata Title by Offer and Acceptance, often called the O&A
- the Joint Form of General Conditions for the Sale of Land, often called the General Conditions
Consumer Protection’s O&A contract guidance says the contract records the property, buyer and seller, price, deposit, balance at settlement, representatives and special conditions. The General Conditions deal with matters including the deposit, settlement, possession, title claims, costs, default and strata disclosure.
Read both documents. The short page containing the price is not the whole agreement.
Which details belong in the written offer?
Every material promise should be stated clearly in the contract. Check the following fields and attachments before signing:
| Offer detail | What to confirm |
|---|---|
| Buyer name | The correct legal name and intended ownership structure |
| Property | Address, title details and whether the sale includes a strata lot |
| Price | The full purchase price in figures and words where required |
| Deposit | Amount, due date and how it will be paid and held |
| Settlement | Date or period that works with finance and other commitments |
| Finance | Whether the standard finance clause applies and any lender named |
| Special conditions | Exact tests, deadlines, responsibility and consequences |
| Included items | Fixtures or chattels that must remain at the property |
Do not rely on a discussion about a dishwasher, shed, repair or settlement date if that point matters to the purchase. Consumer Protection recommends listing items where it may be unclear whether they are fixtures or removable chattels.
How should a subject-to-finance condition be handled?
If a loan is required, complete the finance section accurately. The standard O&A asks whether the finance clause is applicable and allows a preferred lender to be named.
A finance condition is a contractual process, not a general promise that a buyer can withdraw for any funding concern. Where a preferred lender is not named or the standard conditions are changed, the buyer may have duties to use best efforts, provide evidence of an application when properly requested, and promptly notify the seller or agent of approval or rejection.
The contract can remain enforceable until the correct notice is given. A missed finance date does not create a safe automatic exit. Have the clause reviewed before signing if the amount, lender, approval deadline or evidence requirement does not fit your position.
Buyers who need the detail can read the separate first-home buyer guide for WA alongside lender and legal advice.
Which special conditions can protect a buyer?
Special conditions can make an offer dependent on a defined event, but only if the wording creates a clear test and outcome. Consumer Protection identifies conditions for building, plumbing or timber pest inspections, finance, specified repairs, working services and the sale of another property as common examples.

A useful condition should state:
- the action or inspection required
- who must arrange and pay for it
- the deadline
- the standard or result that counts as satisfactory
- who receives written notice
- what happens if the result is not achieved
Avoid writing an important condition from memory or using vague terms such as “subject to satisfactory inspection” without understanding how satisfaction is assessed. Seek legal advice for wording that protects your intended position. All agreed changes and additional conditions should be signed or initialled and dated by the parties.
How much deposit should you offer?
The deposit is a negotiated contract term, not a universal percentage that suits every purchase. The O&A records the amount and payment arrangements, while the General Conditions address how it is held and what may happen on default.
Confirm three points before signing:
- the amount you can make available by the due date
- the approved payment method and trust account details
- the consequences if the payment is late or the contract is not completed
Verify bank details using a trusted contact method before transferring money. Treat any unexpected email changing trust account details as a potential fraud risk and call the agency or settlement representative using a number obtained independently.
What happens after the buyer signs the offer?
The seller can accept the offer, reject it or make a counteroffer. A counteroffer changes the proposal, so the buyer should review every alteration rather than looking only at the price.

Check whether the seller has changed:
- the purchase price
- the deposit or due date
- the settlement date
- a finance deadline
- an inspection condition
- an included item
- any handwritten or attached term
The contract is not complete merely because the parties sound positive. The agent should communicate the signed outcome and provide the executed documents. Record the acceptance time, send the contract to the lender and settlement representative, and diary every condition deadline.
How can a buyer make a strong offer without taking unsafe risks?
A strong offer is easy for the seller to understand and credible to complete. Price matters, but so do a realistic settlement date, a documented finance position and conditions written to produce a clear outcome.
Do not remove a protection simply because another buyer may be interested. Decide the maximum price and minimum safeguards before negotiations begin. If the property is not worth those terms to you, the disciplined response is to let it go.
Boutique Realty Perth’s buying service helps buyers stay informed about current, open-home and off-market opportunities and navigate the offer process. Contract and finance advice should still come from the buyer’s settlement professional, lawyer and lender.
Making an Offer in WA FAQs
Is an offer on a house legally binding in WA?
A signed offer can become a binding contract when the seller accepts it and acceptance is communicated. WA does not provide a mandatory cooling-off period for standard real estate contracts, so obtain advice before signing.
Can I withdraw an offer before the seller accepts it?
An unaccepted offer may be capable of withdrawal, but timing and communication matter. Give any withdrawal promptly in writing and obtain legal advice if acceptance may already have occurred.
Does a seller have to accept the highest offer?
No. A seller chooses whether to accept, reject or counter an offer and may consider conditions, timing and completion risk as well as price.
Can I make an offer subject to a building inspection?
Yes, if the seller agrees to a properly drafted special condition. The clause should define the inspection, deadline, responsibility, relevant defect standard and contractual remedy.
Who can review a WA property contract for a buyer?
A settlement agent can handle conveyancing matters, while a legal practitioner can advise on legal rights and bespoke contract wording. Choose the appropriate adviser before committing to terms you do not understand.
