On a $80,000 salary, you can generally afford a home priced around $285,000 with a 20% down payment and a 30-year mortgage — because lenders cap your total monthly housing costs at about 28% of your gross income, which works out to roughly $1,867 a month. Your exact number depends on your debts, down payment, and local taxes, but the 28/36 rule below will get you a realistic figure in minutes.
What "Afford" Actually Means to a Lender
When you ask "how much house can I afford," you are really asking two different questions. The first is what a lender will approve you for. The second — and more important one — is what you can comfortably pay every month without feeling squeezed. Lenders answer the first question with ratios. You should answer the second one with your actual budget, because a lender's maximum is often more than you will enjoy paying.
The most widely used lender guideline is the 28/36 rule. It has two parts, and the lower of the two results is your real limit:
- Front-end ratio (28%): your total monthly housing costs — mortgage principal and interest, property taxes, homeowners insurance, and HOA dues — should not exceed 28% of your gross monthly income.
- Back-end ratio (36%): your total monthly debt payments, including housing plus car loans, student loans, credit cards, and any other debts, should not exceed 36% of your gross monthly income.
Note that both ratios use your gross income (before taxes), not your take-home pay. That is one reason a lender-approved amount can feel tight in real life — the number is calculated before income tax, retirement contributions, and health insurance come out of your paycheck.
The 28/36 Rule, Step by Step
Here is the calculation for a household earning $80,000 a year:
- Monthly gross income: $80,000 ÷ 12 = $6,667.
- Front-end limit: $6,667 × 0.28 = $1,867 per month for all housing costs.
- Back-end limit: $6,667 × 0.36 = $2,400 per month for all debts combined.
- Subtract your other debts: if you pay $400 a month for a car and $250 for student loans, that is $650 in non-housing debt. So $2,400 − $650 = $1,750 left for housing.
In this example, the back-end ratio is the binding limit: even though the front-end rule allows $1,867, your existing debts pull your housing budget down to $1,750 a month. This is exactly why two households with the same salary can afford very different homes — the one with less debt can borrow more.
How Much House Can You Afford? (Income Table)
Translating a monthly payment into a home price requires a few assumptions. The table below assumes a 20% down payment, a 30-year fixed mortgage at 6.5%, property tax of about 1.1% of the home's value per year, and homeowners insurance of roughly $150 a month, with no HOA dues and no private mortgage insurance (PMI). Rates and taxes vary by location, so treat these as planning figures, not quotes.
| Annual income | Monthly gross | Max housing payment (28%) | Rough home price |
|---|---|---|---|
| $60,000 | $5,000 | $1,400 | ~$210,000 |
| $80,000 | $6,667 | $1,867 | ~$287,000 |
| $100,000 | $8,333 | $2,333 | ~$365,000 |
| $120,000 | $10,000 | $2,800 | ~$443,000 |
Notice the pattern: at today's rates, a comfortable purchase price lands at roughly 3 to 3.5 times your annual income with 20% down. If you put less down, borrow at a higher rate, or live somewhere with high property taxes, that multiple shrinks. If rates fall or you put more down, it grows.

How Your Down Payment Changes the Math
Take a $300,000 home at a 6.5% rate over 30 years. With 20% down ($60,000), you borrow $240,000 and your principal-and-interest payment is about $1,517 a month. With 10% down ($30,000), you borrow $270,000, the payment rises to about $1,707 a month, and — because your down payment is under 20% — you also pay PMI, typically $100 to $150 a month on a loan this size. That is roughly $300 a month more for the same house, plus you start with less equity.
That does not mean waiting years to save 20% is always right. A smaller down payment gets you into a home sooner, and in a rising market that can pay off. But go in with your eyes open: PMI stays until you reach 20% equity (on a conventional loan you can then ask your servicer to remove it), and the higher payment is locked in for the life of the loan unless you refinance.
Don't Forget Taxes, Insurance, and PMI
First-time buyers are often surprised by the gap between the mortgage payment they calculated and the payment the lender actually quotes. The difference is the "T" and "I" in PITI — principal, interest, taxes, and insurance:
- Property taxes: these vary enormously by location, from under 0.5% of a home's value per year in some states to over 2% in others. On a $300,000 home, that is the difference between $125 and $500 a month.
- Homeowners insurance: typically $100 to $250 a month depending on the home's value, location, and coverage.
- PMI: required on most conventional loans with less than 20% down, usually 0.3% to 1.5% of the loan amount per year.
- HOA dues: in condos and many subdivisions, $200 to $500 a month is common — and lenders count it in the 28% ratio.
Lenders collect taxes and insurance in an escrow account, so your single monthly payment includes all of it. When you compare homes, compare the full PITI payment, not just principal and interest.
The Comfort Check: What You Can Actually Live With
The 28/36 rule is a lender guideline, not a personal finance law. Before you shop at your maximum, run a comfort check. Take your actual take-home pay, subtract every fixed monthly cost — housing, debts, utilities, groceries, transport, subscriptions, savings — and see what is left. If a payment at the 28% limit leaves you with nothing for emergencies, home repairs, or fun, it is too much house for you, whatever the lender says.
A useful sanity rule: keep your total housing payment under 25% of your take-home pay if you want real breathing room. On $80,000 gross, take-home pay might be around $5,200 a month after taxes and retirement contributions, so 25% of take-home is about $1,300 — noticeably below the $1,867 lender limit. Many buyers are happiest somewhere between the two numbers.
Five Ways to Afford More House (Safely)
- Pay down debts first. Clearing a $400 monthly car payment raises your back-end housing allowance by the same $400.
- Save a bigger down payment. Every extra $10,000 down cuts your loan — and your monthly payment — by about $63 at 6.5% over 30 years, and can eliminate PMI.
- Improve your credit score. Even a half-point lower rate on a $250,000 loan saves about $75 a month.
- Consider a longer search, not a bigger stretch. A slightly smaller home or a different neighborhood often beats a payment that stresses you for 30 years.
- Get pre-approved, not just pre-qualified. Pre-approval verifies your income, debts, and credit, so you shop with a number a lender has actually checked.
Buying a home is the largest purchase most people ever make, and the right number is the one that lets you sleep at night, not the largest number a lender will print.

Frequently Asked Questions
What is the 28/36 rule for buying a house?
The 28/36 rule says your total monthly housing costs should stay under 28% of your gross monthly income, and your total monthly debt payments, including housing, should stay under 36%. Lenders use these ratios to judge affordability, and the lower of the two results sets your housing budget.
How much house can I afford on $80,000 a year?
On $80,000 a year, the 28% rule allows about $1,867 a month in total housing costs, which translates to roughly a $287,000 home with 20% down and a 30-year mortgage at 6.5%. If you carry other debts, the 36% back-end rule may lower that figure.
Does the 28% rule use gross or net income?
Lenders use gross income, meaning your pay before taxes and deductions. Because of this, a lender-approved payment can feel tighter than expected once taxes, retirement contributions, and insurance come out of your paycheck, so it is wise to also check the payment against your take-home pay.
How much house can I afford with no down payment?
With no down payment, your entire purchase price is borrowed, so the same monthly budget buys a smaller home — roughly 20% less than with 20% down — and you will likely pay PMI on a conventional loan. VA and USDA loans are the main routes to buying with no down payment and no PMI for eligible buyers.
