The 28/36 Rule โ€” The Standard for Home Affordability

The most widely used home affordability guideline is the 28/36 rule. Your monthly housing costs (mortgage principal + interest + property taxes + homeowner's insurance) should not exceed 28% of your gross monthly income. Your total debt payments โ€” housing plus car loans, student loans, credit cards, and other obligations โ€” should not exceed 36%. Lenders use these ratios to evaluate mortgage applications, though FHA loans may allow up to 43โ€“50% back-end DTI in some cases.

Hidden Costs First-Time Buyers Miss

The mortgage payment is just the starting point. A realistic monthly housing budget includes: property taxes (0.5โ€“2.5% of home value annually depending on your state), homeowner's insurance ($100โ€“$200/month typically), HOA fees if applicable ($200โ€“$600/month in many communities), PMI if you put down less than 20% ($80โ€“$250/month on a typical loan), and maintenance โ€” budget 1% of the home's value per year for repairs and upkeep. On a $400,000 home, that's $4,000/year or $333/month for maintenance alone.

How a 1% Rate Difference Changes Everything

At 2026 mortgage rates, a 1% difference in interest rate on a $350,000 30-year loan changes the monthly payment by approximately $210 โ€” and the total interest paid by over $75,000. Improving your credit score from 680 to 740+ can shave 0.5โ€“0.75% off your rate. Getting one additional competing lender quote can save 0.25โ€“0.5%. These aren't small differences โ€” they're the difference between affording a home comfortably or being house-poor.

Frequently Asked Questions

How much house can I afford on a $100,000 salary?+
Using the 28% rule, on a $100,000 salary you can spend up to $2,333/month on housing. At 2026 rates of 6.8% with 10% down, this translates to approximately $310,000 in home price โ€” less if you have significant existing debts.
What is the 28/36 rule for home affordability?+
The 28/36 rule says monthly housing costs should not exceed 28% of gross monthly income (front-end DTI), and total debt payments should not exceed 36% (back-end DTI). Lenders use this as a guideline for mortgage approval.
How much down payment do I need?+
Conventional loans require as little as 3% down. FHA loans require 3.5%. However, putting down at least 20% avoids PMI (private mortgage insurance), which adds $100โ€“$300/month on a typical loan.
What is a good debt-to-income ratio for a mortgage?+
Most lenders prefer a front-end DTI under 28% and back-end DTI under 36โ€“43%. FHA loans may allow up to 50% DTI in some cases, but higher DTI generally means higher rates or stricter terms.
