Selling after the divorce is final can make sense when the market or the home's condition favours waiting, or when one spouse wants to buy out the other's share first rather than list at all, since a buyout resets who owns the home without a sale happening.
Either path still requires the non-owning spouse's written consent under The Homesteads Act, 1989 while both names remain connected to the property, so timing does not remove that requirement, only the pressure around it.
A hand-reviewed valuation, done before either spouse commits to a timing decision, gives both sides a real number to weigh the two paths against. Get your hand-reviewed valuation from Joel Dyck.
