Can I Afford to Keep the House After Divorce?

Last reviewed: May 2026

If you're asking this question, you're already asking the right one. Most people who keep the house in a divorce settlement don't lose it because they couldn't make the mortgage. They lose it because the mortgage was the only cost they ran the numbers on.

The honest answer to “can I afford to keep the house” has four parts, and your bank only checks one of them.

Part 1: Can you qualify for the mortgage on your own?

This is the part lenders look at. After divorce, the house has to be in one person's name, which means the spouse keeping it usually has to refinance into a new mortgage solely in their name. Lenders look at your individual income (including any alimony or child support you'll receive, if you can document a stable history of those payments) against your housing costs and other debt.

The standard rule of thumb is the 28/36 rule: housing costs shouldn't exceed 28% of your gross monthly income, and total debt payments shouldn't exceed 36%. Some lenders go higher, especially with strong credit and reserves, but 28/36 is the conservative line that keeps you safe even if your income drops.

If you can't qualify for the mortgage solo, the conversation is over for now — you can't keep the house regardless of what the settlement says. Lenders won't approve an “assumption” of the existing mortgage in most cases; you have to refinance.

Part 2: Can you cover the costs your bank doesn't ask about?

Housing costs are bigger than the mortgage payment. After the divorce, you alone are responsible for:

• Property taxes, which typically rise faster than wages and can jump after a major remodel or assessment change
• Homeowners insurance, which has been increasing 8–15% per year in many U.S. markets
• HOA dues if applicable
• Major maintenance: a new roof every 20–25 years ($10,000–$30,000), HVAC every 15–20 years ($8,000–$15,000), water heater every 10–15 years ($1,500–$3,000), exterior paint every 7–10 years
• Routine maintenance: a common rule is 1–2% of the home's value per year for ongoing upkeep

A useful sanity check: take your full anticipated monthly housing cost (mortgage + taxes + insurance + HOA + 1% of home value annualized monthly for maintenance), and ask whether that number — not just the mortgage — fits inside your post-divorce budget.

Part 3: Can you cover everything else in your post-divorce life?

This is where most “I'll keep the house” decisions break down years later. If keeping the house consumes 35% of your gross income (a not-unusual outcome for a refinanced single-income household), you have 65% left to fund:

• Income taxes (now likely filing single, with a smaller standard deduction than married-filing-jointly)
• Healthcare (you may be losing coverage through your spouse's employer; ACA marketplace coverage often costs $400–$800/month for a healthy adult plus more for kids)
• Retirement contributions you're now making solo
• Child-related costs that aren't covered by child support
• Transportation, food, clothing, and basic life expenses
• Some kind of emergency fund

The math that matters isn't whether you can afford the mortgage. It's whether you can afford the mortgage AND retirement contributions AND healthcare AND everything else. Skipping retirement contributions to keep the house is one of the most common — and most expensive — mistakes people make in divorce. If your post-divorce budget can't fund both, the deeper question becomes whether your settlement actually lasts long enough to retire on.

Part 4: Is the house actually the best use of the equity?

Even if you can afford to keep the house, the question of whether you SHOULD often comes down to opportunity cost. The equity in the house, if taken instead as liquid assets in the settlement, can:

• Generate income (a $300,000 brokerage account at a 4% withdrawal rate produces $12,000/year)
• Be split across multiple accounts (401(k), IRA, brokerage, cash) for tax flexibility
• Be invested in retirement assets that compound for 20+ years before being touched

Real estate, by contrast, generates no income (it costs you taxes and maintenance every year), is illiquid (selling takes months and costs ~6–10% in transaction fees), and concentrates your net worth in a single asset.

This isn't an argument for selling the house. It's an argument for treating “keep the house” as a real financial decision with real trade-offs, not a default. The flip side — taking retirement instead — has its own trade-offs covered in detail on the house vs. 401(k) page.

The capital gains trap most divorcing homeowners miss

If you keep the house and sell it later as a single person, the IRS only lets you exclude up to $250,000 of capital gain from federal tax under IRC § 121. While you were married, that exclusion was $500,000 on a joint return.

If you bought the house for $500,000 and it's worth $1,200,000 when you sell, the gain is $700,000. As a single filer, you'd exclude $250,000 and owe federal capital gains tax on $450,000 — potentially $90,000 or more, depending on your tax bracket and state. As a married couple, the same sale would have excluded the first $500,000 and only taxed $200,000.

This is a significant hidden cost of keeping the house in high-appreciation markets. Selling jointly during the divorce process — before the marital exclusion is gone — and splitting the proceeds can be substantially more tax-efficient than one spouse keeping the house and selling years later.

There are exceptions and partial-exclusion rules that can help (the IRS recognizes divorce as a qualifying event for partial exclusion, and one spouse can sometimes count the other's continued use toward the two-year residence test). But the baseline math should be on the table before you decide to keep the house.

A note on California specifically

If you're in California, there's an additional consideration: your property tax basis. California's Proposition 13 caps annual increases in assessed value at 2%. A house bought decades ago at a low purchase price often has a property tax bill far below what a comparable new purchase would be assessed at. Inter-spousal transfers in a divorce are exempt from reassessment, so the spouse keeping the house preserves the low tax basis. If you're considering selling and buying a similar home in your area, the new home's property taxes could be 3–10x what you're paying now. This is a real argument for keeping the house even when the pure cash-flow math is borderline. Confirm specifics with a California family lawyer or CPA.

Frequently asked questions

Can I assume the existing mortgage instead of refinancing?

Most conventional and FHA mortgages are not assumable, which means the spouse keeping the house has to refinance into a new loan in their name alone. VA loans are sometimes assumable. If you're not sure, ask your loan servicer in writing — but plan on a refinance as the default scenario.

What if I can't qualify for the mortgage on my own?

You have a few options: a co-signer (a parent, often), a non-occupant co-borrower, taking more of the settlement in income-producing assets to bolster your debt-to-income ratio, or accepting that selling and splitting the proceeds is the realistic path. Don't agree to keep the house in the settlement before you've talked to a lender about whether you can actually refinance.

How much should I budget for ongoing maintenance?

A common rule of thumb is 1% of the home's value per year, plus a major-systems reserve for items like roof and HVAC. For a $600,000 home, that's $6,000/year in routine costs plus a building reserve for the bigger items. Older homes need more; newer homes need less in the early years.

If I keep the house, do I have to buy out my spouse's equity?

In most settlements, yes. The spouse keeping the house “buys out” the leaving spouse's share of the equity, either in cash, by taking on more of the marital debt, or by giving up other assets of equivalent value (often retirement accounts). This is the moment when “house vs. 401(k)” becomes a live trade-off.

Is it ever a mistake to keep the house?

Yes. The most common mistake is keeping a house whose costs leave you unable to fund retirement on a single income, or keeping a house that ties up so much of the settlement that you have no liquid emergency reserve. The second most common is keeping a house in a high-appreciation market, then selling years later and discovering the $250,000 capital gains exclusion isn't enough.
