Cost of Keeping the House Calculator

Last updated July 2, 2026

Keeping the family home in a divorce seems emotionally intuitive — it's familiar, stabilizing for children, and avoids the disruption of another move. The financial reality is often more complicated, and keeping the house can be one of the most financially damaging decisions in a divorce settlement if the numbers aren't carefully examined. The spouse who keeps the home takes on the full mortgage payment, property taxes, insurance, and maintenance — costs that were previously shared — on a single income that may already be reduced. If offsetting the other spouse's equity share requires refinancing at a higher rate or cashing out retirement accounts, the cost rises further.

The analysis requires comparing the full ongoing cost of ownership — mortgage, taxes, insurance, maintenance at 1 to 2 percent of value annually — against the local rental market for a comparable home. In many cases, the monthly cost of keeping the home exceeds the cost of renting something comparable by $500 to $1,500 per month, a gap that strains single-income budgets while tying up equity that could generate investment returns if deployed differently. Selling the home and splitting the equity often provides both parties with a more financially flexible outcome — a liquid asset that can be invested or used as a down payment on individually affordable housing — even when it feels emotionally inferior to staying.

The keeping-the-house calculation shows the true monthly all-in cost on one income — mortgage, taxes, insurance, and a realistic maintenance budget — and compares it with comparable local rent. If the ownership cost exceeds comparable rental by more than $300 to $400 per month, the financial argument for keeping the home weakens significantly, and the equity might serve your post-divorce financial security better if liquidated and invested.
