Laurel Starks — a divorce real estate expert who has handled hundreds of divorce home sales and wrote the book on the subject, The House Matters in Divorce — cuts the decision down to its skeleton: a separating couple only has three options. Keep everything as it is, put the home in one partner's name, or sell.
And the very first question that decides between them, she argues, is brutally simple: can either of you actually afford to keep it? If the honest answer is no, the decision has already been made — everything after that is strategy for a good exit, not a fight over the house.
That's exactly what the calculator above tests. But "can I" is only half the question. Starks — and twenty years of my own mediation files — say the decision really runs on four questions:
1. Can you qualify — on your income alone?
Two households will now run on the income that used to support one. A lender doesn't care what the house means to you; it cares about your ratios. That's Steps 5 and 6 of the calculator — and it's worth knowing your numbers before a lender knows them.
Starks describes what mortgage professionals see constantly: a spouse absolutely determined to keep the home — right up until the buyout payment is put in front of them on paper, at which point many realize it's simply beyond their budget. Getting to that moment in a two-minute calculator, rather than three months into a negotiation you've anchored around keeping the house, is the whole point of this page.
2. Can you carry it — month after month, alone?
Qualifying is the floor, not the finish line. The mortgage payment travels with property taxes, insurance, utilities on a house sized for a bigger household, and maintenance you now face alone — the roof, the plumbing, the yard, the surprises. Starks warns that a home kept at any cost can quietly turn its owner into a servant of the house: current on the payment, but with nothing left for the kids' activities, savings, or any kind of life around it. Add the opportunity cost — every dollar the house absorbs is a dollar not rebuilding your post-divorce financial footing.
This is where I put my CDFA hat on with clients: we model the next five to ten years, not the next mortgage payment.
3. If the plan depends on support — how reliable is it?
Planning to make it work with child or spousal support? Starks is blunt about the risk, and Ontario experience matches: a court order mandates payments; it doesn't guarantee them. Payors lose jobs, self-employed income swings, and child support has an expiry date that may arrive sooner than the mortgage does. If your teenager is sixteen, the income you're budgeting around could step down within a few years. Her advice, which I echo in every mediation: if the income source is shaky, plan conservatively.
(The calculator handles this correctly, by the way — support you pay and support you receive move your lender ratios in opposite directions, and both are in the math.)
4. Do you actually want it — or does it just feel unthinkable to lose?
This is the question nobody asks themselves in the first month. The home is an emotional anchor — Starks observes that in her hundreds of cases, everyone underestimates the impact of losing it. But she also tells the other story: clients for whom the house held mostly painful memories, and selling it was the most liberating step of the entire divorce.
Her hardest-won finding is about what emotion does to the decision itself. Divorce triggers genuine fight-flight-freeze responses, and people make six-figure housing decisions from inside that state — fighting for the house as a trophy, clinging to it for security when selling makes more sense. The cost is measurable: Starks estimates that when people act on emotion, it can set back their financial recovery "by as much as seven years."*
The antidote is the same in her book and in my practice: get the real numbers in front of you early, and make the decision with your eyes open.

What about the kids?
"I'm keeping it for the children" is the most common — and most honourable — reason on this page. Sometimes it's right: continuity of home, school, and neighbourhood is real. But Starks offers a caution worth sitting with: it's a noble instinct that isn't automatically the right answer, and parents shouldn't presume they know what their kids need without genuinely probing it. A financially strained parent in a house they can barely hold is not stability — and children read financial stress fluently.
In mediation, the kids' housing question and the money question get solved together — sometimes the answer is a buyout, sometimes a deferred sale timed to the school calendar, sometimes a fresh start. The point is to choose it, not default to it.
