How Much House Can You Really Afford on Your Salary?
Here's the short version: most people can comfortably afford a home priced around three to five times their annual income, with a monthly housing payment under 28% of gross monthly income. But the price tag a lender approves you for and the price you can actually live with are often two very different numbers — and the gap between them is where budgets break.
The quick answer: the 28/36 rule
The fastest sanity check in home buying is the 28/36 rule. It's the rough guideline lenders and financial planners have leaned on for decades:
- 28% — the front-end ratio: your total monthly housing payment shouldn't exceed 28% of your gross (pre-tax) monthly income. "Housing payment" means principal, interest, property taxes, and insurance — together known as PITI.
- 36% — the back-end ratio: all your monthly debt payments combined — housing plus car loans, student loans, credit card minimums — shouldn't exceed 36% of gross monthly income.
So if you earn $6,000 a month before tax, the 28% line is about $1,680 for housing, and the 36% line is about $2,160 for all debts together. Whichever limit you hit first is your real ceiling. Some loan programs stretch these numbers higher, but the further you push past them, the tighter your month-to-month life gets.
What lenders actually look at
The 28/36 rule is a starting point, not the whole story. When a lender decides how much to hand you, four things do most of the heavy lifting:
- Income: steady, documentable income is king. Lenders favor predictable salaries; variable or freelance income usually needs a two-year track record.
- Existing debts: your debt-to-income ratio is the single biggest lever. A car payment of a few hundred dollars can knock tens of thousands off the home price you qualify for.
- Down payment: more money down means a smaller loan, a lower monthly payment, and often a better interest rate.
- Credit score: a higher score unlocks lower rates. Even a fraction of a percent on a 30-year loan adds up to a lot of money over time.

Beyond the mortgage: the costs people forget
The mortgage is just the headline. The true cost of owning a home includes a stack of expenses that don't show up in a sticker price:
- Property taxes: these vary widely by location and are typically bundled into your monthly payment. They also tend to rise over time.
- Homeowners insurance: required by lenders, and in some regions it has climbed sharply in recent years.
- Maintenance: a common rule of thumb is to budget around 1% of the home's value per year for upkeep — roofs, appliances, and HVAC systems don't last forever.
- HOA fees: condos and many planned communities charge monthly dues that can rival a small car payment, and they count against your budget too.
This is why a payment that looks fine on paper can feel suffocating in real life. Always run your estimate using the full payment — taxes, insurance, and any HOA included — not just principal and interest.
How your down payment and PMI change the math
Your down payment does two jobs at once: it shrinks the loan, and it decides whether you'll pay private mortgage insurance. With a conventional loan, putting down less than 20% usually triggers PMI — an extra monthly charge that protects the lender, not you, and adds nothing to your equity.
A bigger down payment lowers your payment, can earn you a better rate, and lets you skip PMI once you cross the 20% mark. A smaller one gets you into a home sooner but raises the monthly cost. There's no single right answer — it's a trade-off between buying now and buying cheaply. The key is to model both scenarios so the choice is informed, not accidental.
A worked example
Let's put it together. Say a household earns $90,000 a year — that's $7,500 gross per month — and carries a $400 car payment and $150 in student loans.
| Figure | Amount |
|---|---|
| Gross monthly income | $7,500 |
| 28% housing ceiling | ~$2,100 |
| 36% total-debt ceiling | ~$2,700 |
| Existing monthly debts | $550 |
| Room left for housing under 36% | ~$2,150 |
Both rules land this household around a $2,100 housing payment. After carving out taxes, insurance, and maybe an HOA fee, the slice left for principal and interest might be roughly $1,600–$1,800 — which, depending on rates, points toward a home in the rough range of three to four times their income. That's a comfortable zone, not a stretch.
How to afford more (responsibly)
If the number comes back smaller than you hoped, you have real levers — and none of them involve simply ignoring the math:
- Kill existing debt: paying off a car loan can instantly free up hundreds in monthly budget and raise your ceiling.
- Raise your credit score: a better rate means a lower payment for the same price, or more house for the same payment.
- Grow the down payment: more upfront cash shrinks the loan and can eliminate PMI.
- Buy a touch under your max: leaving headroom gives you breathing room for surprise repairs and rising taxes.
