How Much House Can You Actually Afford?

A friend of mine got pre-approved for $450,000 last spring. She earns $95,000 a year, has a car payment and some student loans, and walked out of the bank feeling like a winner. Six months into homeownership, she called me late at night: “I don’t think I can actually afford this.”

She could. Technically. The math the lender ran said so. But affording a house on paper and affording one in real life turned out to be two different things. That gap is exactly what this guide is about.

If you’ve searched for how much house can I afford, you’re asking the right question. Just make sure you get the honest answer, not the one that sells you the biggest loan. Here’s the real math, the rules that matter, and the costs calculators leave out.

Why “How Much House Can I Afford” Is the Wrong Question

Here’s the thing nobody at the bank will say out loud: what you qualify for and what you can comfortably live with are two different numbers. When you’re figuring out how much house can I afford, remember that lenders don’t care if you eat rice and beans for five years. They run your debt-to-income ratio, check a few boxes, and hand you a number. Their risk model assumes you’ll prioritize the mortgage over everything else, because statistically, most people do.

That’s not a plan. That’s a hope.

The question worth asking isn’t “what’s the maximum loan someone will give me?” It’s “what monthly payment lets me sleep at night, keep saving, and still have a life?” Answer that, and you’ll get a home price that works in the real world. Our first-time home buyer guide covers the full process, but this math is the foundation.

The 28/36 Rule, Explained Like a Human

Every serious conversation about how much house can I afford starts with the 28/36 rule. Lenders, financial planners, and housing counselors all use it. It has two parts:

• 28% (front-end ratio): Your total housing costs, mortgage principal, interest, property taxes, homeowners insurance, and HOA fees, should stay at or under 28% of your gross monthly income. That’s income before taxes, by the way.
• 36% (back-end ratio): All your monthly debts combined, housing plus car payments, student loans, credit card minimums, child support, should stay at or under 36% of gross monthly income.

Whichever number is lower wins. Let me show you what that looks like with real money.

Say you earn $75,000 a year. That’s $6,250 a month before taxes.

• 28% of $6,250 = $1,750/month max for all housing costs
• 36% of $6,250 = $2,250/month max for all debts combined

Now suppose you have $500 in monthly debts: a car payment, some student loans. Your housing budget under the back-end rule becomes $2,250 minus $500 = $1,750. Both rules land on $1,750 here, so that’s your maximum housing payment. It has to cover everything, not just the mortgage.

One quick caveat: the 28/36 rule is a ceiling, not a target. Plenty of happy homeowners spend 20 to 25% of their income on housing and use the difference to save, invest, and take actual vacations.

Do the Math Yourself: A Real Worked Example

Calculators are fine, but you should understand the math behind them, because someday a lender will quote you a number and you’ll want to know whether to believe it. Let’s walk through Dana, a composite of several real buyers I’ve talked to.

Dana’s situation: $85,000/year salary ($7,083/month gross), $350/month car payment, $200/month student loans, good credit, $65,000 saved for a down payment.

Step 1: Find the housing ceiling. 28% of $7,083 = $1,983/month for housing. 36% of $7,083 = $2,550, minus $550 in existing debts = $2,000. The lower number wins: $1,983/month.

Step 2: Split out the non-mortgage costs. That $1,983 has to cover PITI: principal, interest, taxes, insurance. Let’s estimate property taxes at $250/month and insurance at $125/month (these vary wildly by state). That leaves about $1,608 for principal and interest.

Step 3: Convert the payment to a loan amount. At roughly 6.75% on a 30-year fixed mortgage, every $1 of monthly payment supports about $154 of loan. So $1,608 × 154 ≈ $247,600 loan.

Step 4: Add the down payment. Dana has $65,000 saved. $247,600 ÷ 0.80 = a home price around $309,000, with 20% down of about $62,000.

Step 5: Check the upfront cash. Down payment ($62,000) plus closing costs of 2 to 5% ($6,200 to $15,500) means Dana needs roughly $68,000 to $78,000 in cash at closing, before moving costs or the emergency fund she must keep separate.

Notice what just happened. The 28/36 rule gave Dana a monthly payment. Working backward gave her a home price. And the cash check told her whether she’s actually ready.

What Different Incomes Actually Buy in 2026

Here are ballpark home prices by income, assuming a 20% down payment, a 30-year fixed rate near 6.75%, and typical taxes and insurance. Your local property taxes can swing these numbers a lot, so treat them as starting points.

• $60,000/year → max housing ~$1,400/month → home around $200K to $230K
• $75,000/year → max housing ~$1,750/month → home around $260K to $280K
• $85,000/year → max housing ~$1,983/month → home around $300K to $315K
• $100,000/year → max housing ~$2,333/month → home around $360K to $390K
• $150,000/year → max housing ~$3,500/month → home around $540K to $580K

Surprised by how modest these look next to prices in your area? That’s the affordability gap in one picture. It doesn’t mean buying is impossible, it means the down payment, the debt payoff, and the location choice matter enormously.

The Hidden Costs Nobody Puts in the Calculator

This is where affordability gets honest. The mortgage is the headline, but homeownership has a long tail of costs that renters never see. Miss these and your budget bleeds out slowly.

• Maintenance and repairs: 1 to 2% of the home’s value per year. On a $300,000 home, that’s $3,000 to $6,000 annually. Roofs leak. Furnaces die at the worst possible moment. Water heaters have a sense of drama. Budget it monthly, like a bill, and you’ll never be blindsided.
• Property taxes that rise. That $250/month estimate? It can jump when your county reassesses. In high-tax states, property taxes alone can add $500 to $1,000 a month to your payment.
• Homeowners insurance, and then some. Standard policies don’t cover floods or earthquakes. Depending on where you buy, you may need extra policies.
• HOA fees: $0 to $500+ a month. They cover amenities and common areas, but they also rise, and special assessments can land without warning.
• The utility jump. Going from a 700-square-foot apartment to a 1,800-square-foot house can double or triple your electric, gas, and water bills. Ask the seller for a year of utility history.
• Closing costs: 2 to 5% of the price. On a $300,000 home, that’s $6,000 to $15,000 in lender fees, title insurance, and appraisals. This is cash, not financed.
• Moving, furniture, and the first-year tax. Movers, a lawn mower, curtains, a plunger at 2 a.m. First-year homeowners routinely spend $5,000 to $10,000 on things they never budgeted.

A home that looks affordable on the mortgage alone can quietly become unaffordable once these stack up. Build them into your number from the start. For the full picture of what trips buyers up, see our rundown of the mistakes first-time buyers make.

Three Other Rules Worth Knowing

The 28/36 rule is the industry standard, but it’s not the only smart way to think about this. Knowing a few alternatives gives you a sanity check from multiple angles.

1. The 2x income rule (the conservative one). Your mortgage should be no more than twice your annual income. Earning $85,000? Cap the loan at $170,000. It’s strict, but people who follow it almost never become house poor.

2. The 25% take-home rule (the lifestyle one). Keep your housing payment at or under 25% of your take-home pay. This accounts for taxes, which the 28% rule ignores.

3. The 3 to 4x income rule (the quick one). Your home price should be 3 to 4 times your annual income. It’s rough, but it’s a decent 10-second gut check when you’re scrolling listings.

Try all four rules on your situation. If three of them agree and one disagrees, dig into why.

What Moves Your Number Up or Down

Your affordable home price isn’t fixed. When people ask how much house can I afford, they often treat the answer as permanent. It’s not. These are the levers that change it, and knowing them tells you exactly what to work on before you buy.

• Credit score. The difference between a 680 and a 760 score can mean half a percentage point or more on your rate. On a $250,000 loan, that’s roughly $80 to $100 a month, which translates to tens of thousands in buying power.
• Down payment size. Bigger down payment means a smaller loan and a lower payment. Hit 20% and you also dodge PMI, private mortgage insurance, which typically costs $100 to $200 a month. But don’t drain every dollar to get there, you’ll see why below.
• Existing debt. Here’s a rule of thumb: every $100 a month in debt payments costs you roughly $15,000 in home price at current rates. Kill the car payment before you buy and you might afford a meaningfully better home, or the same home with breathing room.
• Interest rates. A single percentage point move in rates changes your buying power by roughly 10 to 12%. This is why timing matters less than people think and rate-shopping matters more: even a quarter-point difference between lenders is real money over 30 years.
• Loan type. FHA loans allow higher debt-to-income ratios, up to 43 to 50%, with as little as 3.5% down, but they come with mortgage insurance premiums. VA loans offer no down payment and no PMI for eligible veterans. Conventional loans are cheapest long-term if you can hit 20% down.
• Location taxes. Two identical $350,000 homes can have wildly different monthly costs if one sits in a 2.5% property tax state and the other in a 0.7% one. Always run the numbers for the actual zip code.

The “House Poor” Test: 7 Warning Signs

Being house poor means your home technically fits your budget but leaves you stressed, cash-strapped, and one surprise away from trouble. Realtor.com’s guide to what it means to be house poor is worth a read, but here’s the quick self-test. If you’re nodding along to more than two of these, you’re buying too much house:

• You’d have no emergency fund left after closing costs
• A $2,000 furnace repair would go straight on a credit card
• Vacations, hobbies, and eating out become “maybe next year”
• You can’t keep contributing to retirement while paying the mortgage
• One job loss would put you in panic mode within 60 days
• You’re counting on a raise or promotion that hasn’t happened yet
• The payment makes you check your bank app with dread instead of confidence

My friend from the intro hit four of these. She refinanced and picked up extra work, but she lost a year of sleep learning the lesson. You don’t have to.

When to Wait vs. When to Buy

Sometimes the honest answer to how much house can I afford is “not yet,” and that’s not a tragedy. Here’s how to tell:

Buy when: your housing payment fits under 28% with all hidden costs included, you have the down payment plus 3 to 6 months of expenses left over, and your job and location are stable for at least 5 years.

Wait when: you’d need to drain your emergency fund for the down payment, your debt-to-income is already near the ceiling, you’re buying mostly because you’re afraid prices will run away from you, or a career or family change is likely in the next year or two.

Waiting isn’t losing. Every month you wait while paying down debt and growing savings is a month your future home gets more affordable.

Frequently Asked Questions

What is the 28/36 rule for buying a home?

The 28/36 rule says your total housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income, and all your debts combined should not exceed 36%. Lenders use it as a guideline for how much house can I afford calculations, and it’s the most widely trusted starting point for buyers doing their own math.

How much house can I afford on $75,000 a year?

On a $75,000 salary ($6,250/month gross), the 28% rule gives you a maximum housing payment of about $1,750/month including taxes and insurance. At current rates near 6.75% with 20% down, that supports a home price roughly between $260,000 and $280,000, depending on your local property taxes and existing debts. An affordability breakdown with more income scenarios and FAQs can help you fine-tune the number.

What does it mean to be house poor?

Being house poor means spending so much of your income on housing that you have little left for savings, emergencies, or enjoying life. It usually happens when buyers max out their mortgage approval without accounting for hidden costs. The fix is buying below your maximum approval and keeping a real emergency fund.

Can I buy a house with only 3% down and still afford it?

Yes, loan programs exist with 3 to 5% down, especially for first-time buyers. But a smaller down payment means a bigger loan, a higher monthly payment, and PMI until you reach 20% equity. Sometimes waiting a year to save a bigger down payment is cheaper than years of PMI.

How much should I have saved before buying a house?

Aim for the down payment, plus 2 to 5% of the price for closing costs, plus 3 to 6 months of living expenses kept separate as an emergency fund. On a $300,000 home with 10% down, that’s roughly $30,000 down plus $6,000 to $15,000 closing plus your emergency cushion. Never drain your last dollar to close.

Does student loan debt affect how much house I can afford?

Directly. Lenders count your monthly student loan payments in the back-end 36% ratio, which shrinks your housing budget dollar for dollar. As a rough guide, every $100 a month in debt payments costs you about $15,000 in home price at current rates.
