How Much House Can I Afford? A First-Time Buyer's Guide

Figuring out how much house can I afford is the first real step in buying your first home — and it is also the step most first-time buyers get wrong. Many people start by browsing listings, fall in love with a home, and only then discover the monthly payment is far higher than they expected. A smarter approach is to work backwards: start with your income, debts, savings and credit, and let those numbers set a realistic price range before you tour a single house.

In this guide, you will learn the rules lenders use, how to calculate your own affordable price in minutes, what costs buyers often forget, and how to increase what you can afford without stretching your budget to breaking point.

What Does "Afford" Really Mean?

Affording a house is not just about getting approved for a mortgage. A lender may approve you for more than you can comfortably pay every month. True affordability means you can pay the mortgage, taxes, insurance and upkeep, still save for emergencies, and still live your life — without feeling house-poor.

That is why you need two numbers: the maximum a lender will lend you, and the maximum you are comfortable paying. Your budget should be the lower of the two. If the lender says $450,000 but a $450,000 home would leave you with no savings, your real limit is lower.

The 28/36 Rule: The Starting Point Lenders Use

One of the most widely used guidelines for answering "how much house can I afford" is the 28/36 rule. It has two parts:

• 28% rule: Spend no more than 28% of your gross monthly income on housing costs — principal, interest, property taxes, homeowners insurance, mortgage insurance and homeowners association (HOA) dues.
• 36% rule: Spend no more than 36% of your gross monthly income on all debts combined, including housing, car loans, student loans, credit cards and personal loans.

For example, if you earn $6,250 per month before tax ($75,000 per year), 28% is $1,750. That is a useful ceiling for your total housing payment. If you already pay $400 a month for a car and student loans, your total debt ceiling under the 36% rule is $2,250, leaving $1,850 for housing after those debts — still close to the 28% figure. Lenders today often allow a higher debt-to-income ratio, sometimes up to 43% or even 50% for some loan types, but a higher approval does not make the payment comfortable.

Your Debt-to-Income Ratio (DTI) Matters More Than Your Salary

Your debt-to-income ratio, or DTI, is your total monthly debt payments divided by your gross monthly income. It is one of the first things a lender checks, and it often matters more than your salary alone. Two buyers earning $80,000 can afford very different homes if one has $900 a month in other debts and the other has none.

To calculate your DTI, add up your minimum monthly payments for credit cards, car loans, student loans and any other debts, add your proposed housing payment, and divide by your gross monthly income. A DTI below 36% is strong. Between 36% and 43% is workable for many conventional and FHA loans. Above 45%, your options narrow and your payment may feel tight.

The 3x Income Rule: A Quick Sanity Check

Another simple shortcut is the 3x rule: aim for a home price no more than three times your gross annual income. On a $75,000 salary, that suggests a home around $225,000. On $100,000, it suggests about $300,000. This rule is deliberately conservative. In expensive cities it may feel unrealistic, and in lower-cost areas you may be able to go higher, especially with a large down payment. Use it as a reality check, not as a final answer. If a home costs five times your income, ask yourself honestly where the extra money will come from every month.

How to Calculate How Much House You Can Afford: Step by Step

Follow these five steps with your own numbers.

Step 1: Work out your gross monthly income. Divide your annual salary before tax by 12. Include stable bonuses or second income only if a lender would count it.

Step 2: List your monthly debts. Include car payments, student loans, minimum credit card payments and child support. Do not include groceries, utilities or subscriptions — lenders focus on debts that appear on your credit report.

Step 3: Set your target housing payment. Multiply your gross monthly income by 0.28. Then check the 36% rule: multiply income by 0.36 and subtract your other debts. Use the lower result.

Step 4: Subtract taxes, insurance and other housing costs. Property tax, homeowners insurance, private mortgage insurance (PMI) if your down payment is under 20%, and HOA dues all come out of that housing budget. What is left is roughly what can go to principal and interest.

Step 5: Work backwards to a home price. Use a mortgage calculator with a realistic interest rate and a 30-year term, add your down payment, and see what price fits your target payment. Then get pre-approved to confirm it with a lender.

Worked Example: $75,000 Income

Suppose you earn $75,000 a year, or $6,250 a month. You have a $300 car payment and a $200 student loan payment, and you have $30,000 saved for a down payment. Your 28% housing ceiling is $1,750 a month. Your 36% total debt ceiling is $2,250, minus $500 in other debts, leaving $1,750 for housing — the same figure.

If property taxes are about $250 a month, insurance is $150, and PMI is $100, that leaves about $1,250 for principal and interest. At a 6.5% rate on a 30-year loan, that supports a loan of roughly $198,000. Add your $30,000 down payment, and your affordable home price is around $228,000. If you buy in an area with lower taxes, or you put 20% down and avoid PMI, the same income could support a higher price. The point is not the exact number — rates and taxes change — but the method: every cost reduces what is left for the loan itself.

How Much House Can I Afford? Table by Income

The table below gives rough estimates to help you compare incomes. It assumes a 10% down payment, a 6.5% interest rate, a 30-year fixed mortgage, and that taxes, insurance and PMI take about $500 a month combined. Actual amounts will vary by location, credit score, loan type and interest rate, so treat these as starting points, not guarantees.

Annual income	Monthly income	Target housing payment (28%)	Approximate home price	10% down payment
$50,000	$4,167	$1,167	$150,000 - $170,000	$15,000 - $17,000
$75,000	$6,250	$1,750	$225,000 - $250,000	$22,500 - $25,000
$100,000	$8,333	$2,333	$300,000 - $340,000	$30,000 - $34,000
$125,000	$10,417	$2,917	$375,000 - $425,000	$37,500 - $42,500
$150,000	$12,500	$3,500	$450,000 - $510,000	$45,000 - $51,000

If your income is above or below this range, use the same method with your own 28% figure. A dual-income household should be careful: if you qualify on two incomes, make sure you could still manage the payment if one income dropped for a few months.

Do Not Forget the Costs Beyond the Mortgage

First-time buyers often focus only on principal and interest, but the full monthly cost — often called PITI plus PMI and HOA — is what you will actually pay.

• Principal and interest: the loan itself. A lower rate or a shorter term changes this sharply.
• Property taxes: these vary widely by state and county and can rise over time.
• Homeowners insurance: required by lenders, and higher in areas prone to floods, wildfires or hurricanes.
• Private mortgage insurance (PMI): usually required on a conventional loan if your down payment is under 20%. It can add $100 to $300 a month.
• HOA dues: common in condos and newer communities, sometimes $200 to $500 a month or more.
• Maintenance and repairs: budget about 1% of the home price per year for upkeep, plus utilities that may be higher than in a rental.

Closing costs are separate again — typically 2% to 5% of the home price — and you will also need moving costs, furniture and an emergency fund after you move in.

Other Factors Lenders Look At

Income and debts are only part of the picture. Your credit score affects your interest rate, and even a small rate difference changes your affordable price by tens of thousands of dollars. A higher score can mean a lower rate and a lower monthly payment for the same home. Your employment history, savings and cash reserves also matter: lenders like to see that you can keep paying if something goes wrong. Finally, the loan type matters. FHA loans allow lower down payments and lower credit scores, VA loans can offer no down payment for eligible veterans, and conventional loans may offer better terms if your credit is strong.

How to Afford More — Safely

If the numbers say you cannot yet afford the home you want, you have options that do not require taking on a risky payment. Paying down high-interest debts lowers your DTI and frees up room for housing. Improving your credit score, even by 20 to 40 points, can reduce your rate. Saving a larger down payment reduces the loan amount and may remove PMI. Looking in a nearby neighbourhood with lower taxes, or choosing a smaller home or a condo, can also bring the price into range. First-time buyer programs, down payment assistance and grants can help too — check state and local programs before you assume you need 20% down.

Common Mistakes to Avoid

Do not shop at your maximum pre-approval amount without checking the monthly payment. Do not forget taxes, insurance and HOA dues. Do not drain your emergency fund for the down payment. Do not take on new car loans or credit card debt while you are house hunting, because it can lower your credit score and raise your DTI. And do not assume your income will rise quickly to cover a tight payment — plan for the income you have now.

Frequently Asked Questions

How much house can I afford on $70,000 a year?

Using the 28% rule, your target housing payment is about $1,633 a month. Depending on your debts, down payment, taxes and interest rate, that often points to a home in the $210,000 to $240,000 range, but get a personalised estimate from a lender and a mortgage calculator before you set your budget.

How much house can I afford with no down payment?

It is possible with a VA loan, a USDA loan in an eligible rural area, or some down payment assistance programs, but you will borrow more and your monthly payment will be higher. You will still need money for closing costs, moving and an emergency fund.

Is the 28/36 rule still relevant in 2026?

Yes, as a budgeting guide. Lenders may approve higher ratios, but the rule helps you avoid a payment that leaves no room for savings, repairs and everyday life. In high-cost areas, many buyers go above 28% — if you do, do it knowingly and with a clear safety margin.

Does my credit score change how much house I can afford?

Yes. A better score usually means a lower interest rate, a lower monthly payment and a higher affordable price, while a lower score can mean a higher rate or a more expensive loan. Check your credit early so you have time to fix errors or improve your score before you apply.

Should I use my maximum pre-approval amount?

Not automatically. Pre-approval shows the maximum a lender will lend, not the amount that is comfortable for you. Choose a price where the full monthly payment — including taxes, insurance, PMI and HOA — fits your budget with savings left over.

Conclusion

Answering "how much house can I afford" starts with honest numbers, not with a listing you love. Use the 28/36 rule, calculate your DTI, include taxes, insurance, PMI, HOA and maintenance, and compare the result with the table above. Then get pre-approved, keep an emergency fund intact, and shop in a price range you can sustain for years — not just for the first month. The right home is one you can afford comfortably, not just one you can win a bidding war for.
