This is the #1 question every homebuyer asks — and it's the right one to start with. Before you fall in love with a house, you need to know your real number. Not just what a bank will approve, but what you can actually afford without stretching yourself thin.
In this guide I'll break it down simply — the rules lenders use, the formulas that actually matter, and how to figure out your personal number right now.
A general rule of thumb: you can afford a home that costs 2.5 to 3.5 times your annual gross income. So if you earn $80,000/year, you can likely afford a home between $200,000 and $280,000.
But that's just the starting point. Read on for the full picture.
When you apply for a mortgage, lenders don't just look at your income — they look at two specific ratios to decide how much they'll lend you.
Your monthly mortgage payment (including principal, interest, property taxes and insurance) should not exceed 28% of your gross monthly income.
If you earn $7,000/month gross, your max mortgage payment should be no more than $1,960/month (28% × $7,000).
Your total monthly debt — mortgage + car payments + credit cards + student loans — should not exceed 43% of your gross monthly income. This is called your Debt-to-Income ratio or DTI.
If you earn $7,000/month and have $500 in other debt payments, your max mortgage payment would be: (43% × $7,000) − $500 = $2,510 − $500 = $2,010/month.
Here's a quick reference table based on different income levels, assuming a 6.5% interest rate, 30-year term, and 10% down payment:
| Annual Income | Max Monthly Payment | Estimated Home Price | Down Payment |
|---|---|---|---|
| $50,000 | ~$1,167/mo | ~$155,000 | ~$15,500 |
| $75,000 | ~$1,750/mo | ~$235,000 | ~$23,500 |
| $100,000 | ~$2,333/mo | ~$315,000 | ~$31,500 |
| $125,000 | ~$2,917/mo | ~$395,000 | ~$39,500 |
| $150,000 | ~$3,500/mo | ~$475,000 | ~$47,500 |
Note: These are estimates. Your actual number depends on your credit score, existing debts, property taxes, and current interest rates.
Your credit score directly impacts your interest rate — and therefore how much home you can afford. The difference between a 620 and a 760 score can mean thousands of dollars per year in interest.
| Credit Score | Typical Rate (2026) | Monthly Payment on $300K |
|---|---|---|
| 760+ | ~6.2% | ~$1,836/mo |
| 700–759 | ~6.5% | ~$1,896/mo |
| 640–699 | ~7.0% | ~$1,996/mo |
| 620–639 | ~7.5% | ~$2,098/mo |
Car payments, student loans, and credit card minimums all eat into your DTI ratio. The less debt you carry, the more home you can afford. If possible, pay down high-balance debts before applying.
In 2026, mortgage rates are hovering between 6.0% and 6.5%. Even a 0.5% difference in your rate can change your buying power by $20,000–$30,000. This is why working with a licensed MLO who monitors rates daily matters.
Don't just ask "how much will the bank approve me for?" Ask "what monthly payment am I comfortable with?" Those are two very different numbers. Your home should be an asset, not a source of stress.
Stop guessing. Get a real pre-approval from a licensed MLO who will look at your actual numbers and tell you exactly what you can afford — and the best loan program for your situation.
