Unconditional contracts explained — the risks of buying with no conditions in NSW and Victoria

The short version

An unconditional contract is one with no conditions left to satisfy — no cooling-off, no "subject to finance", no building-and-pest clause. Once contracts are exchanged, you are committed to settle. If your loan falls over or the inspection turns up a problem, that's your problem: you either complete the purchase or you lose your deposit, and possibly more.

Buyers go unconditional to look like the safest bet in a competitive sale — sellers love certainty, and agents push for "clean" offers. The certainty is real. So is the risk, and it sits entirely on the buyer.

What "unconditional" actually means

Most private-treaty contracts start life conditional. Common conditions are subject to finance (the deal only proceeds if your lender approves the loan on this property), subject to a building and pest inspection, and sometimes subject to the sale of your own home. A contract becomes unconditional when every condition is either met or waived — or when you sign one that never had any conditions in the first place.

A contract bought at auction is unconditional by design: there is no cooling-off period at auction, and auction contracts don't carry finance or inspection conditions. Winning the bid is going unconditional in a single motion.

The three protections you give up

Cooling-off

In NSW a private-treaty buyer normally gets five business days to change their mind, unless they sign a Section 66W certificate waiving it. In Victoria most private-sale buyers get three clear business days, which don't apply to auction sales or a sale made within three clear business days before or after a public auction. Going unconditional means letting that window go — or never having it.

Subject to finance

A finance condition lets you walk away (usually with your deposit back) if your lender won't approve the loan. Waive it and an approval that later falls through no longer releases you — you still have to find the money to settle.

Building and pest

A building-and-pest condition lets you exit, or renegotiate, if the inspection finds serious defects. Without it, you buy the property in whatever condition it's actually in, faults and all.

Why buyers do it anyway

In a tight market a seller choosing between two similar offers will usually take the one with fewer strings. An unconditional offer — or one with a signed 66W in NSW — signals you won't pull out, so agents encourage it and buyers use it to get ahead. The trade is simple and rarely spelled out: you make the seller's position safer by making your own riskier.

Where it goes wrong

The classic failure is finance. A pre-approval is not a guarantee: the lender still has to value the specific property and confirm the loan, and a valuation that comes in below the price can shrink what they'll lend. On an unconditional contract, none of that lets you out. If you can't settle on the due date, the seller can serve a notice to complete, charge penalty interest on the unpaid balance while you're late, and — if you still can't settle — terminate, keep your deposit (typically 10%), and resell. If the resale fetches less than your price, they can pursue you for the shortfall and their costs. A failed unconditional purchase can cost well beyond the deposit.

What to check before you sign

1. Unconditional finance, not pre-approval. A lender's confirmed approval on this specific property, with the valuation already done — not a pre-approval letter.
2. The building and pest inspection is done and read. Order it and review the report before you commit, because you can't rely on the clause you're waiving.
3. The contract, in full. Deposit amount, settlement period, penalty-interest rate and every special condition — all fixed the moment you go unconditional.
4. Your deposit and settlement funds are ready. Know exactly where the money is coming from and that it will be available on time.
5. A buffer for the valuation gap. If the bank values the property below the price, can you cover the difference? On an unconditional deal, you have to.

Common questions

Can I get out of an unconditional contract?

Not on your own say-so. Once you're unconditional, the exits are narrow — mainly a genuine breach by the seller, or the seller agreeing to release you (usually for a significant payment). Changing your mind, or your finance falling through, is not enough.

What happens if my finance falls through?

You are still obliged to settle. If you can't, the seller can serve a notice to complete, charge penalty interest, and ultimately terminate and keep your deposit — and pursue any shortfall if they resell for less. This is the single biggest reason to line up unconditional finance before waiving the finance condition. Our finance-risk guide explains how approvals and valuations come apart over time.

Is an auction contract always unconditional?

Effectively, yes. There's no cooling-off at auction and the contract carries no finance or inspection conditions, so a winning bid binds you immediately. Everything you'd normally do during a conditional period has to be done before you raise your hand.

Should I ever make an unconditional offer?

Only once you've genuinely removed the risk — unconditional finance confirmed, inspections done and read, and the contract reviewed in full. If those boxes are ticked, an unconditional offer can win you the property. If any of them is a maybe, you're gambling your deposit to look good on paper. Confirm your position with a conveyancer or solicitor before you commit.
