How Much House Can I Afford? (The Honest Answer Based on Your Salary)
Before you start browsing Zillow or visiting open houses, you need to answer the most important question in real estate: How much house can I actually afford?
Most buyers start with a dream home and try to make the math work later. But the smartest way to buy a home is to start with your salary and expenses, then find the house that fits your life—not the other way around. Here is exactly how banks look at your income, and how you can calculate your own "safe" home-buying budget.
The Gold Standard: The 28/36 Rule
Financial planners and mortgage lenders typically use the 28/36 rule to determine your maximum loan amount:
1. The 28% Front-End Ratio: Your total monthly housing payment (Principal, Interest, Taxes, and Insurance—or PITI) should not exceed 28% of your gross monthly income (your pay before taxes).
2. The 36% Back-End Ratio: Your total monthly debt payments (housing costs + car loans + student loans + credit card minimums) should not exceed 36% of your gross monthly income.
If your salary is $100,000 per year, your gross monthly income is $8,333.
• Your maximum housing payment (28%) = $2,333/month
• Your maximum total debt (36%) = $3,000/month
Real Income-Based Examples
How do these rules look at different salary levels? Assuming a 7% interest rate and a 10% down payment, here are the general "safe" purchase prices:
| Annual Salary | Monthly Gross Income | Max Housing Payment (28%) | Estimated Home Price |
|---|---|---|---|
| **$60,000** | $5,000 | $1,400 | **$180,000 – $210,000** |
| **$80,000** | $6,667 | $1,867 | **$260,000 – $290,000** |
| **$120,000** | $10,000 | $2,800 | **$410,000 – $450,000** |
| **$150,000** | $12,500 | $3,500 | **$530,000 – $580,000** |
*Note: These estimates vary significantly based on your local property taxes and insurance rates.*
The Hidden Costs of Affordability
When calculating your budget, remember that the mortgage is only one part of the cost. You must also account for:
• Property Taxes: Usually 1% to 2% of the home's value per year.
• Homeowners Insurance: Typically $1,000 to $2,500 per year.
• PMI (Private Mortgage Insurance): Required if your down payment is less than 20%.
• Maintenance & Repairs: A good rule of thumb is to set aside 1% of the home's value every year for repairs. On a $400,000 house, that’s $333/month.
Tips to Increase Your Home-Buying Power
1. Improve Your Credit Score: A score above 740 can get you a significantly lower interest rate, which adds tens of thousands of dollars to your "affordability" bucket.
2. Lower Your DTI (Debt-to-Income): Paying off a car loan or a credit card balance can free up hundreds of dollars in your monthly "36%" limit, allowing for a larger mortgage.
3. Save a Larger Down Payment: The more you put down, the less you borrow, and the lower your monthly payment becomes. Putting 20% down also removes the cost of PMI.
The Bottom Line
Just because a bank *approves* you for a certain amount doesn't mean you should spend it. Banks don't account for your childcare costs, travel habits, or retirement goals. Use our Mortgage Calculator to run different scenarios and find a monthly payment that lets you sleep comfortably at night.
