What you can afford depends on your income, not your age
The amount of house you can afford in retirement is determined by the same math as before retirement: your monthly income, your debts, and the interest rate you may have access to for. The difference is that your income is now fixed. You cannot count on raises, bonuses, or a second job to cover a payment that stretches you thin.
Most lenders will approve a mortgage if your total monthly debt payments—including the new mortgage—do not exceed 43% of your gross monthly income. In retirement, your gross income is your Social Security, pensions, investment withdrawals, or rental income, whichever applies to you. If you have a mortgage already, that payment counts against the 43% threshold too.
The practical ceiling is usually lower than what a lender will approve. Financial advisors often suggest keeping your housing payment to 25% to 30% of gross monthly income in retirement, because you have less flexibility if something breaks or your property taxes rise.
Key Takeaways
- Your affordable house price depends on your fixed monthly retirement income and the interest rate you can get, not on your age or retirement account balance.
- Lenders typically allow housing payments up to 43% of gross monthly income, but 25% to 30% leaves room for property taxes, insurance, maintenance, and unexpected costs.
- Paying off your current mortgage before retirement reduces the income you need to may have access to for a new one and frees up monthly cash flow.
- Downsizing to a lower-priced home or moving to a lower-tax state can stretch your retirement income further than buying the same house you had before.
- Property taxes, insurance, and maintenance costs often rise faster than your fixed income, so a house that feels affordable at purchase may become a burden later.
Calculate your maximum affordable payment
Start with your total monthly retirement income. Add up Social Security, any pension payments, and any withdrawals you plan to make from savings or investments each month. This is your gross monthly income for lending purposes.
Multiply that number by 0.30 (or 0.25 if you want a tighter margin). That is your target maximum housing payment. The housing payment includes principal, interest, property taxes, homeowners insurance, and mortgage insurance if you put down less than 20%.
For example: if your gross monthly income is $4,000, your target housing payment is $1,000 to $1,200. If property taxes and insurance in your area run $300 per month, you have $700 to $900 left for principal and interest. At a 7% interest rate on a 30-year mortgage, that payment covers roughly a $120,000 to $155,000 loan. Add your down payment to find your affordable purchase price.
This calculation assumes you have no other debts. If you carry credit card balances, car loans, or other obligations, subtract those monthly payments from your housing budget first.
How your down payment affects what you can afford
A larger down payment lowers your monthly payment and removes the requirement for mortgage insurance. If you have $100,000 saved and can put 20% down, you can afford a $500,000 house. If you put down only 5%, you can afford a $263,000 house with the same $100,000—because the remaining $95,000 goes toward mortgage insurance and a larger loan balance.
In retirement, a larger down payment also means a smaller loan to repay over time. A 15-year mortgage instead of a 30-year one builds equity faster but raises your monthly payment. Most retirees choose the 30-year term to keep payments lower, even if they plan to pay it off early.
If you are selling a current home to buy a retirement home, your equity from the sale becomes your down payment. Many retirees downsize—selling a $400,000 house and buying a $250,000 one—to free up $150,000 in cash and lower their monthly payment at the same time.
Why paying off your current mortgage first matters
If you still owe money on your current home when you retire, that payment counts against your debt-to-income ratio. Paying it off before you retire removes that obligation and increases the housing payment you can afford on a new purchase.
More importantly, entering retirement without a mortgage payment gives you breathing room. If your property taxes or insurance rise, or if you need to replace a roof or HVAC system, you are not also paying a lender. Many financial advisors recommend this as a priority in the five to ten years before retirement.
If you cannot pay off your mortgage before retirement, you can still buy another home—but your new payment will be smaller, or you will need higher income to may have access to. Some retirees keep their current home and rent it out instead, using the rental income to help may have access to for a new mortgage elsewhere.
Property taxes and insurance will rise faster than your income
A house that costs $1,200 per month in payments today may cost $1,500 in five years if property taxes and insurance increase by 5% annually—a realistic rate in many states. Your Social Security and pension do not rise that fast. Over 20 years, that same house could cost $2,000 or more per month in taxes and insurance alone.
Before you buy, research the property tax rate and homeowners insurance costs in the area where you are looking. Some states tax retirees more heavily than others. Florida and Texas have no state income tax but can have high property taxes. New Jersey and Illinois have high property taxes. Some counties offer property tax breaks for seniors, but these vary widely and often have income limits.
Add maintenance and repairs to the equation. A house that is 20 or 30 years old may need a new roof, foundation work, or plumbing repairs. Budget 1% to 2% of the home's value annually for maintenance, or set aside $200 to $400 per month for a $250,000 house. This is money that does not go toward your mortgage payment but is part of your true housing cost.
Downsizing or relocating can lower your costs
If your current home is worth more than you need, selling it and buying something smaller or in a lower-cost area is one of the most direct ways to stretch your retirement income. Selling a $500,000 house and buying a $300,000 one frees up $200,000 in equity and lowers your monthly payment by several hundred dollars.
Moving to a state with lower property taxes or cost of living has the same effect. A retiree moving from California to North Carolina, or from New York to South Carolina, often finds that the same house costs half as much in property taxes and insurance. The difference compounds over 20 or 30 years of retirement.
Downsizing also reduces maintenance costs and utility bills. A smaller home is cheaper to heat, cool, and repair. If you are in a condo or active adult community, some maintenance is included in your homeowners association fee, which is predictable and does not rise as fast as individual property taxes.
Renting instead of buying in retirement
Renting removes the uncertainty of property taxes, insurance, and major repairs. Your rent is fixed for the lease term, and the landlord handles maintenance. For retirees on a tight budget, this predictability is valuable.
The trade-off is that rent rises over time and you build no equity. A $1,500 rent today may be $1,800 in five years. Over 30 years of retirement, rent increases can outpace the cost of owning a paid-off home. But if you do not have the savings to buy outright or the income to may have access to for a mortgage, renting may be the only option—and it is a legitimate one.
Some retirees rent for the first few years of retirement while they adjust to their fixed income, then buy once they understand their true spending patterns. Others rent permanently and invest the money they would have used for a down payment, letting it grow to cover future rent increases.
Frequently Asked Questions
Can I get a mortgage in retirement if I am on Social Security only?
Yes, but the mortgage amount will be smaller. Lenders count Social Security as income. If you receive $2,500 per month in Social Security, you can afford roughly a $1,075 housing payment (43% of income). If property taxes and insurance are $400, you have $675 left for principal and interest—roughly a $115,000 loan at 7% over 30 years. A larger down payment or additional income (pension, investments, rental income) increases what you can afford.
What if I want to buy a house that costs more than I can afford?
You have three options: increase your down payment to lower the loan amount, find a less expensive house, or add another source of income (such as part-time work or rental income from another property). A co-borrower with income can also help you may have access to, but their debts count against the ratio too. Stretching beyond what your income supports often leads to financial stress when unexpected costs arise.
Should I pay off my mortgage before I retire?
It depends on your interest rate and income. If your mortgage rate is 3% or 4% and you have other debts at higher rates, paying off the mortgage first may not be the best use of money. But if you have no other debts and want the security of a payment-free home in retirement, paying it off removes a major monthly obligation and gives you flexibility if your income drops or costs rise.
Does my age affect how much house I can afford?
Age does not affect the mortgage calculation itself, but it affects how long you will own the home. A 30-year mortgage taken at age 65 means payments until age 95. Some lenders have age limits or require shorter loan terms for older borrowers. A 15-year mortgage is more common for retirees. The shorter the loan term, the higher your monthly payment for the same loan amount.
What if property taxes in my area are very high?
High property taxes reduce the house price you can afford, because more of your housing budget goes to taxes instead of the mortgage payment. If your area has 2% property taxes and another has 0.5%, the same house costs $300 more per month in the high-tax area. Research tax rates before you buy, and consider whether moving to a lower-tax state makes sense for your retirement plan.
