How much house can you afford? It is the most important number in the entire homebuying process – more important than any listing price or a single day’s interest rate. Get it right and homeownership builds your wealth; get it wrong and it quietly drains it. Here is a clear, real-numbers way to find your number in 2026, when the average 30-year fixed mortgage rate sits around 6.5%.
How much house can you afford? Start with the 28/36 rule
Lenders and financial planners lean on one simple guideline: the 28/36 rule.
- 28% front-end: your total monthly housing payment (principal, interest, property taxes, and insurance – together called PITI) should stay at or below 28% of your gross monthly income.
- 36% back-end: all of your monthly debt payments combined (housing plus car loans, student loans, minimum credit card payments) should stay at or below 36% of gross income.
Take a household earning $80,000 a year – that is about $6,667 a month gross. The 28% rule caps housing at roughly $1,867 a month. The 36% rule caps total debt at about $2,400, so if you already pay $400 toward a car and student loans, your housing ceiling drops accordingly.
Turn your maximum payment into a home price
Your monthly payment is not just principal and interest. At a 6.5% 30-year rate, principal and interest run about $6.32 per month for every $1,000 borrowed. But taxes, insurance, and possibly private mortgage insurance (PMI) eat into that same monthly budget.
Working the $1,867 housing budget backward: set aside roughly $450 a month for property taxes and homeowners insurance, leaving about $1,417 for principal and interest. At 6.5%, that supports a loan of roughly $224,000. With a 10% down payment, that is a home priced near $249,000; with 20% down, closer to $280,000. Lower the rate or raise the down payment and the affordable price climbs.
Do not forget the hidden costs of owning
The mortgage is only part of the picture. Budget for property taxes (around 1.1% of home value a year on average, but wildly different by state), homeowners insurance, PMI if you put down less than 20%, HOA dues where they apply, and maintenance. A common planning rule is to set aside about 1% of the home’s value per year for upkeep – $2,500 a year on a $250,000 home. Closing costs add another 2% to 5% of the loan amount upfront.
The down payment reality in 2026
Twenty percent down is the classic target because it avoids PMI and lowers your loan, but it is not required. Conventional loans go as low as 3% down, and FHA loans as low as 3.5% with more flexible credit requirements. The tradeoff: a smaller down payment means a bigger loan, PMI, and a higher monthly payment. If buying sooner with 5% down beats waiting three years to reach 20% (while rents and prices rise), the smaller down payment can still be the right call – just run both scenarios.
How 2026’s rates change the math
Rates matter enormously. The same $224,000 loan costs far less per month at 4% than at 6.5%. As of mid-2026, the 30-year fixed averages around 6.5% (the 15-year is closer to 5.85%), with inflation running near 4.2% and the Federal Reserve meeting again later this month. Rates change weekly, so check the current average from Freddie Mac before you set your budget, and remember your personal rate depends on your credit score, down payment, and loan type.
A simple affordability checklist
- Calculate 28% of your gross monthly income – that is your housing ceiling.
- Subtract estimated taxes, insurance, and PMI to find your principal-and-interest budget.
- Convert that to a loan amount at today’s rate, then add your down payment for a target price.
- Confirm total debt stays under 36% of income.
- Leave room for maintenance, closing costs, and an emergency fund – do not spend to the absolute max.
The cheapest mistake in homebuying is buying less house than the bank will approve you for. Lenders tell you the most you can borrow; your budget should tell you the most you should.
