How Much House Can You Afford? (2026)
Figuring out how much house you can afford is about far more than what a lender is willing to approve you for — it’s about what you can comfortably pay each month without straining your broader financial life. With mortgage rates still elevated in 2026, getting this calculation right matters more than ever.
The Standard Affordability Rules
The 28/36 Rule is the most widely used guideline among lenders:
- 28% rule: Your monthly housing payment (principal, interest, taxes, and insurance — often abbreviated PITI) shouldn’t exceed 28% of your gross monthly income.
- 36% rule: Your total debt payments (housing plus car loans, student loans, credit cards, etc.) shouldn’t exceed 36% of your gross monthly income.
Some lenders will approve borrowers up to a 43–45% debt-to-income ratio for certain loan types, but staying closer to 28/36 gives you more breathing room and reduces financial stress.
A Worked Example
Suppose your household gross monthly income is $8,000:
- 28% for housing: Maximum PITI payment of about $2,240/month.
- 36% for total debt: Maximum total debt payments of about $2,880/month, leaving roughly $640 for non-housing debt (car loan, student loans, etc.) if you’re at the housing cap.
What Today’s Rates Mean for Your Budget
As of mid-September 2026, the average 30-year fixed mortgage rate is around 6.76%, while 15-year fixed rates sit closer to 5.97%. At a 6.76% rate on a 30-year fixed loan, every $100,000 borrowed costs roughly $650 per month in principal and interest alone — before taxes, insurance, or HOA fees. That means a $2,240 monthly housing budget (from the example above) supports a mortgage of roughly $330,000–$350,000, depending on your local property tax and insurance costs. tradingeconomicsFortune
Beyond the Mortgage Payment: Full PITI
Your total monthly housing cost isn’t just principal and interest. It includes:
- Principal & Interest — the loan payment itself.
- Property Taxes — varies enormously by state and county, from under 0.5% to over 2% of home value annually.
- Homeowners Insurance — increasingly significant in disaster-prone regions, where premiums have risen sharply in recent years.
- PMI (Private Mortgage Insurance) — required on most conventional loans with less than 20% down, typically 0.5%–1.5% of the loan amount annually until you reach 20% equity.
- HOA Fees — if applicable, for condos or planned communities.
The Down Payment’s Role
A larger down payment reduces your loan amount, lowers your monthly payment, and — critically — can eliminate PMI once you hit 20% down. Common down payment benchmarks:
- 20%: Avoids PMI entirely on conventional loans and typically secures the best rates.
- 3%–5%: Common minimums for first-time buyer programs and certain conventional loans.
- 0%: Available through VA loans (for eligible veterans/military) and USDA loans (for eligible rural properties).
Don’t Forget Closing Costs and Reserves
Beyond the down payment, buyers typically need 2%–5% of the purchase price in closing costs (loan origination fees, title insurance, appraisal, inspection). Lenders and financial planners also recommend keeping 3–6 months of expenses in reserve after closing — buying a home that uses every last dollar you have leaves no cushion for the inevitable repairs and surprises of homeownership.
Front-End vs. Back-End Ratios in Practice
Lenders will calculate both ratios precisely during underwriting, but you can estimate your own affordability before ever talking to a lender using the same math. This lets you shop with a realistic price range in mind rather than falling in love with a home outside your comfort zone based on what a lender says you’re approved for — approval limits and comfortable limits are often different numbers.
Renting vs. Buying Considerations
At current rate levels, the monthly cost of owning (PITI) frequently exceeds the cost of renting a comparable property in many U.S. metro areas, especially in the first few years before you’ve built meaningful equity. Buying still makes long-term financial sense in many cases due to equity building and fixed-rate payment stability (rent tends to rise annually, while a fixed-rate mortgage payment doesn’t), but it’s worth running the actual numbers for your specific market rather than assuming buying is always better.
Bottom Line
A practical affordability check in 2026: keep your total housing payment at or below 28% of gross monthly income, keep total debt below 36%, budget for the full PITI (not just principal and interest), and maintain a healthy reserve after closing. With 30-year rates near 6.7%–6.8%, run your specific numbers carefully — a home that looked affordable at 2021’s sub-3% rates may not fit the same budget today.
