The question "how much house can I afford?" is the single most important financial question most Americans will ever ask. Get it right and you build wealth through homeownership. Get it wrong and you end up house-poor — technically a homeowner, but unable to save, invest, or enjoy life because every spare dollar goes to your mortgage.
The short answer: most lenders will approve you for a home costing 3 to 5 times your gross annual income, as long as your total debt-to-income ratio stays below 43%. But the amount a bank is willing to lend you and the amount you should actually spend are two very different numbers. This guide walks you through both.
The 28/36 Rule: The Gold Standard for Affordability
The 28/36 rule is the standard framework that financial planners and lenders use to determine how much house you can comfortably afford. It has two parts:
The 28% Rule (Front-End Ratio): Your total monthly housing costs — mortgage principal, interest, property taxes, and homeowner's insurance (PITI) — should not exceed 28% of your gross monthly income. If you earn $6,000 per month before taxes, your maximum housing payment should be $1,680.
The 36% Rule (Back-End Ratio): Your total monthly debt payments — housing costs plus car loans, student loans, credit card minimums, and any other debt obligations — should not exceed 36% of your gross monthly income. Using the same $6,000 example, your total debt payments should stay under $2,160.
Here's how this plays out at different income levels:
| Annual Income | Monthly Gross | Max Housing (28%) | Max Total Debt (36%) | Approximate Home Price |
|---|---|---|---|---|
| $50,000 | $4,167 | $1,167 | $1,500 | $180,000–$220,000 |
| $75,000 | $6,250 | $1,750 | $2,250 | $270,000–$330,000 |
| $100,000 | $8,333 | $2,333 | $3,000 | $360,000–$440,000 |
| $150,000 | $12,500 | $3,500 | $4,500 | $540,000–$660,000 |
These ranges assume a 20% down payment, a 6.5% interest rate, and typical property tax and insurance costs. Your actual affordability depends heavily on your specific location, down payment, interest rate, and existing debts. Use our Home Affordability Calculator to see your exact number.
What Lenders Actually Look At
When you apply for a mortgage, the lender evaluates four primary factors, often called the Four C's:
Credit Score
Your credit score is the single biggest factor determining both whether you'll be approved and what interest rate you'll receive. A score of 740 or above typically qualifies for the best rates. A score between 620 and 740 will get you approved but at higher rates. Below 620, conventional loans become difficult, though FHA loans are available down to 580 (or 500 with 10% down). The difference between a 680 and 760 credit score on a $300,000 mortgage can mean $50,000+ in additional interest over 30 years.
Debt-to-Income Ratio (DTI)
Your DTI is the percentage of your gross monthly income that goes to debt payments. Most conventional lenders cap DTI at 43%, though some will go to 50% with compensating factors like excellent credit or significant assets. FHA loans allow DTI up to 57% in some cases. To calculate yours: add up all monthly debt payments (car loan, student loans, credit card minimums, child support — not utilities or groceries) and divide by your gross monthly income.
Down Payment
A larger down payment reduces your loan amount, eliminates or reduces PMI, and may qualify you for better rates. Here are the common down payment thresholds:
- 20% down: No PMI required. Best rates. Standard conventional.
- 10-19% down: PMI required ($50-$200/month on a $300K loan). Removed once you hit 20% equity.
- 3-5% down: Conventional loans allow as low as 3%. PMI is higher.
- 3.5% down: FHA minimum for credit scores 580+.
- 0% down: Available for VA loans (veterans) and USDA loans (rural areas).
A common mistake first-time buyers make: draining their entire savings for the down payment. You need to keep reserves for closing costs (2-5% of home price), move-in expenses, and an emergency fund. Going house-poor on day one is a recipe for financial stress.
Employment and Income Stability
Lenders typically want to see two years of stable employment history. Self-employed borrowers need two years of tax returns showing consistent income. Recent job changes aren't necessarily disqualifying, but gaps in employment can be. If you're planning a career change, it's generally better to buy before switching.
The Hidden Costs Most Buyers Forget
Your mortgage payment is not your total housing cost. The real monthly cost of homeownership includes several expenses that renters never think about:
Property Taxes: These average 1.1% of home value nationally but range from 0.28% in Hawaii to 2.47% in New Jersey. On a $350,000 home, that's $81/month in Hawaii versus $720/month in New Jersey. Always check the specific property tax rate for your target area — it varies dramatically by county and can increase after purchase.
Homeowner's Insurance: Typically $1,000-$3,000 per year depending on location, home value, and coverage. Homes in flood zones, hurricane regions, or wildfire areas can cost significantly more. Get quotes before making an offer.
Private Mortgage Insurance (PMI): Required if your down payment is less than 20%. Typically costs 0.3-1.5% of the loan amount per year. On a $280,000 loan, that's $70-$350/month. Use our PMI Calculator to see your exact cost.
Maintenance and Repairs: Budget 1-2% of home value per year. On a $350,000 home, that's $3,500-$7,000 annually ($290-$580/month). New construction requires less; older homes require more. The first year often brings surprise expenses.
HOA Fees: If applicable, these range from $100/month for basic communities to $500+/month for luxury condos. HOA fees tend to increase over time and are mandatory — non-payment can result in liens on your home.
Utilities: Homeowners typically pay 20-40% more in utilities than renters due to larger space, yard maintenance (water), and full responsibility for heating/cooling. Budget $200-$400/month depending on home size and climate.
How Much House Can I Afford on My Salary? Real Examples
Example 1: $60,000 Salary, No Debt, First-Time Buyer
Monthly gross income: $5,000. Using the 28% rule, maximum housing payment: $1,400. With a 5% down payment on a $250,000 home, an FHA loan at 6.5%, and including property taxes, insurance, and PMI, the total monthly payment comes to approximately $2,050 — well above the 28% threshold. A more comfortable target would be $200,000-$220,000 with FHA, or $180,000-$200,000 with conventional financing.
Example 2: $100,000 Salary, $500/Month Student Loans
Monthly gross income: $8,333. The 28% rule allows $2,333 for housing. But the 36% rule is the binding constraint here: maximum total debt is $3,000, minus $500 in student loans leaves $2,500 for housing. With 20% down at 6.5%, a home price around $380,000-$400,000 fits comfortably within both rules.
Example 3: $150,000 Household Income, Two Incomes
Monthly gross income: $12,500. Maximum housing: $3,500. This opens up the $500,000-$600,000 range with 20% down at current rates. However, dual-income households should stress-test against one income: could you make the payment if one person lost their job? Many financial planners recommend qualifying on one income and treating the second as bonus savings capacity.
The 2026 Housing Market Reality
As of early 2026, the average 30-year fixed mortgage rate hovers around 6.5%, down from 7.5%+ peaks in late 2023 but significantly above the 3% rates of 2020-2021. This means monthly payments on a $350,000 home are roughly 40% higher than they would have been three years ago. Median existing home price nationally is approximately $400,000.
The practical implication: buyers in 2026 can afford approximately 20-25% less home than buyers in 2021 at the same income level. This makes the affordability calculation more important than ever.
Strategies to Afford More Home
Improve your credit score before applying. Moving from 680 to 740 can save 0.5-1.0% on your interest rate, which translates to $50-$100/month on a typical loan and $20,000-$40,000 over the life of the mortgage.
Pay down existing debt first. Reducing your DTI from 36% to 28% can increase your maximum home price by 15-20% because lenders consider total debt capacity.
Consider a 15-year mortgage. Rates are typically 0.5-0.75% lower than 30-year, saving you tens of thousands in interest. The monthly payment is higher, but the total cost is dramatically lower. Compare with our Mortgage Calculator.
Explore first-time buyer programs. FHA loans require just 3.5% down. VA loans offer 0% down for veterans. USDA loans offer 0% down in eligible rural areas. State housing finance agencies offer down payment assistance grants. These programs exist specifically to make homeownership accessible.
Don't forget to negotiate. In the current market, sellers are more willing to negotiate than during the 2021-2022 frenzy. Ask for closing cost credits, rate buydowns, or home warranty coverage.
The One Rule That Matters Most
After all the ratios, rules, and calculations, here's the simplest test: can you make the full housing payment and still save at least 15% of your income for retirement? If the answer is no, the house is too expensive. A home should be a foundation for building wealth, not an anchor that prevents it.
Homeownership is one of the best financial decisions most people can make — but only when the math works. Use our Home Affordability Calculator to run the numbers with your specific income, debts, and down payment. It takes 30 seconds and could save you years of financial stress.
