Exit Strategies: What Happens When a Co-Owner Wants Out?
Nobody buys in expecting to leave, but jobs move, relationships end, and money gets tight. Planning the exit before you need it is what keeps a departure from becoming a dispute.

Plan the exit before you sign the entry
Nobody buys into a property planning to leave it. Then a job turns up in another state, a relationship ends, a windfall opportunity appears, or someone just decides they'd rather have the cash. People exit co-ownership for ordinary reasons all the time.
The trick is that the best moment to agree how an exit works is right at the start, while everyone's aligned and nobody's leaving. Trying to negotiate the terms once someone already has one foot out the door is how clean departures turn into expensive ones.
The ways out, and what each one needs
A buyout by the remaining owners is the most common path: the person leaving sells their share to those staying. To make it work you've agreed three things in advance — how the share gets valued (independent valuation, a set formula, or a market appraisal), whether it's paid as a lump sum or instalments, and whether the remaining owners can actually refinance to cover it.
A sale to a third party comes into play when the others can't or won't buy. Here your agreement should give the existing owners a right of first refusal to match any outside offer, and say whether they get any say over who the incoming co-owner is — because you're about to be in business with them.
Selling the whole property is sometimes simply the cleanest answer. It might be triggered by mutual agreement, a pre-set review date ("we'll reassess at five years"), or a forced-sale clause for when owners reach a genuine stalemate.
An emergency exit covers the harder cases — financial hardship, serious damage, a legal problem — and should lay out a faster process so nobody's trapped while the clock runs.
Getting the number right
Valuation is where buyouts live or die. In Australia the usual options are an independent sworn valuation (the most defensible, around $300–$600), an average of two or three agent appraisals (free, less precise), or a pre-agreed formula such as purchase price plus improvements minus depreciation. Pick one in the agreement so you're never arguing about the method and the money at the same time.
The tax you can't ignore
When a co-owner sells their share, capital gains tax usually comes into play. How much depends on how long they've held it — twelve months or more may qualify for the 50% CGT discount — whether the property was their main residence, and what capital improvements were made along the way. The numbers move enough that you should talk to a tax professional before finalising any exit, not after.
A clear exit path protects everyone, including the people staying. Set it down while the relationship is strong, because the version you write under pressure is never as fair as the one you'd write today.
