Can You Afford to Keep the House After Divorce? The Real Math

“I want to keep the house.” It is one of the most common statements divorce attorneys hear, and one of the most emotionally charged decisions in any settlement. The family home represents stability, continuity for children, and a sense of normalcy during a period when everything else feels uncertain. But wanting to keep the house and being able to afford to keep the house are two very different things — and confusing the two can lead to years of financial strain that undermines the very security you were trying to protect.

The question is not whether you can make this month’s mortgage payment. The question is whether you can carry the full, true cost of homeownership on a single income for the next ten, fifteen, or twenty years — while still saving for retirement, building an emergency fund, and maintaining a reasonable quality of life. This article walks through the real math, category by category, so you can make this decision with clarity rather than emotion.

The true monthly cost of keeping the house

When most people think about whether they can afford the house, they think about the mortgage payment. But the mortgage is only one piece of the picture — and in some cases, it is not even the largest one. To get an honest assessment, it is important to account for every recurring housing cost — including the hidden costs most people miss — and add them together into a single monthly number.

Start with the mortgage payment itself, including principal and interest. Then add property tax, which in many areas is collected through your escrow account but is a separate and often substantial cost. Add homeowners insurance, which has been rising in many markets. If you have an HOA, include those monthly or quarterly fees. Next, budget for ongoing maintenance: lawn care, pest control, HVAC servicing, gutter cleaning, and the dozens of small upkeep tasks that keep a house functional. A widely used rule of thumb suggests budgeting 1% to 2% of a home’s value annually for maintenance and repairs, though older homes may require more.

Then there is the cost most people forget entirely: the opportunity cost of equity. If your home has significant equity — say, several hundred thousand dollars — that money is locked inside the property. It is not earning investment returns, it is not providing liquidity for emergencies, and it cannot be easily accessed without selling or taking on debt. When you compare keeping the house to selling it, consider what that equity could potentially do for you if it were invested instead.

Finally, add a line item for capital repairs. Roofs, water heaters, furnaces, plumbing, and appliances all have finite lifespans. When something fails and there is no second income to absorb the cost, a single unexpected repair can derail your budget for months.

State-by-state property tax impact

Property tax is one of the most significant variables in the affordability equation, and it varies enormously depending on where you live. This is not just a state-level difference — rates can vary by county and even by municipality within the same county. Still, understanding the broad state-level landscape can help you calibrate your expectations.

New Jersey has the highest property taxes in the country, with an average annual bill of roughly $9,500. On a home valued at $400,000, that translates to nearly $800 per month just for property tax. Texas, which has no state income tax, compensates in part through property taxes that generally run around 1.7% of home value — meaning a $350,000 home might carry roughly $6,000 per year in property tax. Florida has comparatively moderate property tax rates, often around 0.8% of home value, but homeowners insurance in Florida can be among the most expensive in the nation due to hurricane risk, which may offset the property tax savings considerably.

In Washington state, property tax rates tend to fall in a moderate range, but home values in areas like Seattle and its suburbs are high enough that the dollar amount of the tax bill can still be substantial. The point is this: you cannot evaluate affordability without looking up the actual property tax bill for your specific home, in your specific jurisdiction. Your county assessor’s website will typically have this information, and it is worth checking whether any reassessment is likely after the divorce — some jurisdictions reassess property value upon transfer of ownership.

The refinancing reality check

If both you and your spouse are on the existing mortgage, keeping the house almost always requires refinancing into your name alone. This is not optional — your ex-spouse has a legal obligation on that mortgage, and most lenders will not simply remove a borrower from an existing loan. A refinance is effectively a new loan application, and the lender will evaluate you as if you are buying the house for the first time.

That means your individual income, credit score, debt-to-income ratio, and employment history all need to qualify on their own. For many people, especially those who were secondary earners during the marriage or who are re-entering the workforce, this can be the single biggest obstacle to keeping the house. Lenders typically want to see a debt-to-income ratio below 43%, and some prefer it below 36%. If your total monthly debt obligations — including the new mortgage, car payments, student loans, and any other debts — exceed that threshold relative to your gross monthly income, you may not qualify.

There is also the question of interest rates. If your existing mortgage was locked in during a period of historically low rates, refinancing at current rates could increase your monthly payment significantly even if the principal amount stays the same. The difference between a 3.5% rate and a 7% rate on a $300,000 mortgage is substantial — potentially several hundred dollars per month. This rate increase alone can shift the house from affordable to unaffordable.

Before you commit to keeping the house in your settlement negotiations, it may be wise to get pre-qualified for a refinance so you know whether this path is even available to you. Some people discover too late that they cannot qualify, which can force a sale under time pressure and on less favorable terms.

The 10-year projection: what this house really costs

One of the most revealing exercises you can do is project the total cost of keeping the house forward over ten years. This is different from looking at today’s monthly payment, because costs do not stay flat — they tend to rise, sometimes significantly.

Property taxes generally increase over time. In many jurisdictions, assessed values are adjusted upward periodically, and tax rates themselves may rise as local governments face increasing costs. Homeowners insurance premiums have been rising in many states, driven by factors including climate-related risk, increased construction costs, and reinsurance market dynamics. Maintenance costs tend to increase as homes age — the furnace that works fine today may need replacement in five years, the roof that was new when you bought the house may be approaching the end of its useful life.

When you add all of this up over a decade — mortgage payments, property tax, insurance, maintenance, repairs, and the opportunity cost of equity — the total cost of keeping the house is often far higher than people initially estimate. Some people find that the 10-year cost of keeping a home exceeds the current value of the home itself, particularly when the mortgage balance is still relatively high. Running this projection is not pessimistic — it is prudent.

When keeping makes sense vs. when it doesn’t

Keeping the house can be the right decision under certain circumstances. If you have substantial equity, a low mortgage rate that you would hate to give up, strong and stable income that comfortably covers all housing costs, and children who would benefit from remaining in their school district and social environment, then keeping the house may genuinely serve your long-term interests. Some people also find emotional value in the continuity that staying in their home provides during an otherwise disruptive period, and that psychological benefit is real even if it is difficult to quantify.

On the other hand, keeping the house is often the wrong decision when it requires sacrificing most of your liquid assets in the settlement, when it stretches your monthly budget to the point where you cannot save or invest, when the home is older and likely to need significant capital repairs in the coming years, or when the emotional attachment is the primary driver rather than the financial logic. Many divorce financial planners note that the house is the asset people fight hardest to keep and regret keeping the most — not because the house is bad, but because the financial consequences of keeping it were not fully understood at the time.

It is also worth considering that your housing needs may change in the coming years. A four-bedroom home that made sense for a family of four may feel very different when it is just you, or you and one child who will leave for college in a few years. Downsizing is not a failure — it can be a strategic decision that frees up resources for the things that matter most to you in this next chapter.

The real question: can you afford the house and still save for retirement?

This is the question that separates a comfortable decision from a dangerous one. Many people can technically afford the mortgage payment on a single income. Fewer can afford the mortgage, the property tax, the insurance, the maintenance, the repairs — and still contribute meaningfully to a retirement account, maintain an emergency fund, and have some financial breathing room for unexpected expenses.

If keeping the house means you stop contributing to your 401(k) or IRA for the next several years, you are not just losing those contributions — you are losing the potential compounding growth on those contributions over the decades between now and retirement. Sacrificing retirement savings for the house is one of the most common retirement account mistakes in divorce. For someone in their 40s, every year of missed retirement savings can represent a meaningful reduction in retirement security. The house provides shelter today, but it does not pay for groceries, healthcare, or living expenses in retirement unless you sell it or borrow against it.

Before you finalize your decision, it may be worth running two scenarios side by side: one where you keep the house and one where you sell, downsize, and invest the difference. Compare where each scenario leaves you in 10, 15, and 20 years. Include retirement savings, investment growth, and total housing costs. In many cases, people are surprised to find that the sell-and-invest scenario leaves them in a significantly stronger financial position over time — even after accounting for rent payments. That does not mean selling is always the right choice, but having the data allows you to make the decision with open eyes.
