House hunting has a funny way of starting at the wrong end. You see a place you love, then try to convince yourself the numbers work. The calmer way is to figure out your real budget first, then shop inside it. So if you earn $80,000 a year, how much house can you actually afford? Let’s work it out with a simple, lender-tested rule.
The 28/36 rule, explained
Lenders and financial planners lean on a guideline called the 28/36 rule:
- 28% — your total monthly housing payment (mortgage principal, interest, property taxes, and insurance, often called PITI) should stay under 28% of your gross monthly income.
- 36% — all your monthly debt (housing plus car loans, student loans, credit-card minimums) should stay under 36% of gross income.
It’s not a law, but it’s a sensible ceiling that keeps you from being “house poor.”
Running the numbers on $80,000
| Step | Amount |
|---|---|
| Gross monthly income ($80,000 ÷ 12) | ~$6,667 |
| Max total housing payment (28%) | ~$1,867/month |
| Max total debt (36%) | ~$2,400/month |
So your full housing payment should land around $1,867 a month, assuming you don’t have much other debt. Take out an estimated $400/month for property taxes and insurance, and you’ve got roughly $1,467 a month for principal and interest.
Turning that into a home price
At a 6.5% interest rate on a 30-year loan, a $1,467 monthly principal-and-interest payment supports a loan of about $232,000. Add your down payment, and the home price you can afford looks like this:
- With 10% down: roughly a $258,000 home
- With 20% down: roughly a $290,000 home
So on $80,000 a year with little other debt, a home in the $250,000–$290,000 range is a realistic target. Your exact number shifts with interest rates, taxes, insurance, and your down payment — plug your own figures into the Mortgage Calculator to see it live.
What changes your number (a lot)
- Other debt. A $400 car payment eats straight into your housing budget under the 36% rule, lowering the house you qualify for.
- Interest rates. Even a 1% rate change noticeably moves how much loan a given payment supports.
- Down payment. More down means a smaller loan and — past 20% — no PMI, which frees up monthly room. See What Is PMI and How Do You Avoid It.
- Property taxes and insurance. These vary widely by location and quietly raise your monthly payment.
Don’t forget the costs beyond the mortgage
Affording the payment isn’t the same as affording the home. Budget for closing costs (often 2–5% of the loan), maintenance (a common rule of thumb is ~1% of the home’s value per year), and any HOA dues. A house that’s affordable on paper can strain you if these surprise you later.
A reality check before you shop
Run your real situation through the Mortgage Calculator, then sanity-check the total payment against a 50/30/20 budget using your take-home pay, not gross. Lenders approve you on gross income, but you live on net — and a payment that looks fine to a lender can feel tight in real life.

Frequently asked questions
How much house can I afford on $80,000 a year?
With little other debt, roughly a $250,000–$290,000 home using the 28/36 rule, depending on your down payment, rate, taxes, and insurance.
What’s the 28/36 rule?
Keep housing under 28% of gross monthly income and total debt under 36%. It’s a guideline lenders use to avoid over-lending.
Do I need 20% down?
No — many loans allow less. But under 20% you’ll usually pay PMI, which raises your monthly cost. More down means a bigger house budget.
Should I borrow the maximum I qualify for?
Usually not. Qualifying for a payment and being comfortable with it are different. Leave room for savings, maintenance, and life.
The takeaway
On an $80,000 salary, a home around $250,000–$290,000 is a realistic, comfortable target if you keep other debt low — based on the 28/36 rule. But the right number is personal: run your rate, down payment, taxes, and insurance through the Mortgage Calculator, and judge the payment against your take-home pay, not your gross.
