How Much House Can I Afford? A First-Time Buyer's Complete Guide (2026)
Before you start scrolling through listings and falling in love with kitchens you may not be able to afford, you need to answer one question: how much house can I actually afford? Not how much a lender will approve you for — those are two very different numbers. In 2026, with mortgage rates hovering between 6% and 7.5% and median home prices sitting near $420,000 nationally, getting this number right has never been more important. This guide walks you through the exact math lenders use, the rules of thumb that actually work, and the mistakes that cause first-time buyers to end up house-poor. By the end, you will have a realistic price range and the confidence to shop within it.
Why "Pre-Approved Amount" Is Not Your Budget
When a lender pre-approves you for $400,000, they are telling you the maximum they are willing to lend based on your income, debts, and credit score. They are not telling you that buying a $400,000 home is a good idea for your life. Lenders do not factor in your grocery bill, your daycare costs, your car insurance, your hobbies, or the fact that you like to travel twice a year. They look at income and existing debt payments — that is it. Plenty of buyers who purchased at their maximum approval amount end up feeling financially squeezed within the first year. A 2025 Bankrate survey found that 55% of homeowners reported feeling house-poor at some point after purchasing. The goal is to find the number where your mortgage payment feels comfortable alongside everything else in your life, not the number where you are stretching every month. When you ask "how much house can I afford," the answer should reflect your whole financial picture — not just what a bank is willing to lend.
The 28/36 Rule: Your Affordability Starting Point
The most widely used guideline in mortgage lending is the 28/36 rule, and understanding it gives you an immediate framework for answering how much house you can afford. The first number — 28 — means your total monthly housing costs should not exceed 28% of your gross monthly income. Housing costs include your mortgage payment (principal and interest), property taxes, homeowner's insurance, and HOA fees if applicable. This is called your front-end ratio. The second number — 36 — means your total monthly debt payments, including housing costs plus car loans, student loans, credit card minimums, and any other recurring debt, should not exceed 36% of your gross monthly income. This is called your back-end ratio, also known as your debt-to-income ratio or DTI. Here is a quick example: if your household earns $6,000 per month before taxes, the 28% rule says your housing costs should stay at or below $1,680. If you also have $400 per month in car and student loan payments, the 36% rule says your total debt payments (housing plus everything else) should stay at or below $2,160 — meaning your housing costs should actually cap at $1,760. You take the lower of the two numbers, so in this case, $1,680 is your target maximum housing payment. At current 2026 interest rates near 6.75%, a $1,680 monthly payment on a 30-year fixed mortgage translates to roughly $258,000 in borrowing power. Add your down payment to find your maximum purchase price.
How Much House Can I Afford on My Salary? Real Examples
Abstract rules are helpful, but real numbers make the concept click. Here is how much house you can afford at different income levels using the 28/36 rule and a 6.75% interest rate with 5% down in 2026. If you earn $50,000 per year ($4,167/month gross), your maximum housing payment is about $1,167, which supports a purchase price around $195,000 to $210,000. At $75,000 per year ($6,250/month gross), your maximum housing payment is about $1,750, supporting a purchase price around $290,000 to $310,000. At $100,000 per year ($8,333/month gross), your maximum payment is about $2,333, supporting roughly $385,000 to $410,000. And at $150,000 per year ($12,500/month gross), you are looking at a maximum payment of $3,500, which supports a purchase price of roughly $575,000 to $615,000. These ranges assume minimal existing debt. Every $300 per month in car payments, student loans, or credit card minimums reduces your purchase power by roughly $45,000 to $50,000. That is why paying down debt before buying is one of the most effective ways to afford more house.
Debt-to-Income Ratio: The Number That Actually Decides How Much House You Can Afford
Your debt-to-income ratio, or DTI, is the single most important number in determining how much house you can afford. It is simple math: add up all your monthly debt payments (including your estimated new mortgage payment) and divide by your gross monthly income. Multiply by 100 to get a percentage. Most conventional lenders want to see a DTI of 43% or lower, though some will go up to 45% or even 50% with strong compensating factors like a high credit score or large cash reserves. FHA loans allow DTI ratios up to 57% in some cases. But just because a lender allows a high DTI does not mean it is smart. Financial advisors generally recommend keeping your DTI below 36% for long-term financial health. Every dollar committed to debt payments is a dollar that cannot go toward savings, investing, emergencies, or enjoying your life. When calculating your DTI, include: mortgage payment (use an estimate based on current interest rates), property taxes (roughly 1% to 1.5% of the home's value per year, divided by 12), homeowner's insurance (roughly $100 to $300 per month depending on location), car payments, student loan payments, minimum credit card payments, personal loans, and child support or alimony if applicable. In 2026, the average American household carries about $1,060 in monthly non-housing debt payments, which significantly reduces the mortgage they can qualify for.
What Lenders Look At Beyond DTI When Deciding Your Mortgage Amount
Beyond DTI, lenders evaluate several factors that determine both whether you qualify and what interest rate you receive. Your credit score is the biggest lever on your interest rate — a buyer with a 760 score might get a rate 0.5% to 1% lower than a buyer with a 660 score, which translates to tens of thousands of dollars over the life of the loan. On a $350,000 mortgage, that rate difference means $100 to $200 more per month, or $36,000 to $72,000 over 30 years. Your employment history matters too; lenders like to see at least two years of stable employment, ideally in the same field. Self-employed borrowers typically need two years of tax returns showing consistent or growing income. Your down payment size affects your loan-to-value ratio and determines whether you need to pay private mortgage insurance, which adds $100 to $300 or more per month to your housing costs. Your cash reserves — the money left in your accounts after closing — signal to lenders that you can handle unexpected expenses. Most lenders want to see at least two months of mortgage payments in reserve, and having six months or more can help you qualify for a better rate or a larger loan.
The Hidden Costs Most Home Affordability Calculators Miss
Online affordability calculators give you a starting point, but they almost always underestimate the true cost of owning a home. Here are the expenses that catch first-time buyers off guard. Maintenance and repairs: budget 1% to 2% of your home's value per year. On a $350,000 home, that is $3,500 to $7,000 annually, or roughly $290 to $580 per month. Utilities: homeowners typically pay 15% to 30% more for utilities than renters because houses are larger and you are responsible for water, sewer, and trash in addition to electric and gas. Budget $200 to $400 per month depending on location and home size. Private mortgage insurance (PMI): if your down payment is less than 20%, you will pay PMI, which typically costs 0.5% to 1% of the loan amount per year. On a $300,000 loan, that is $125 to $250 per month. HOA fees: if the home is in a homeowners association, fees can range from $50 to $500 or more per month. The national average HOA fee in 2026 is approximately $275 per month. Furnishing and move-in costs: a mostly empty house needs furniture, window coverings, possibly appliances, and moving expenses. Budget $5,000 to $15,000 depending on how much you already own. When you ask how much house you can afford, you need to account for all of these costs — not just the mortgage payment.
A Practical Way to Test Your Home Affordability Number
Before you commit to a mortgage payment, test it. Take the difference between your estimated mortgage payment (including taxes, insurance, and PMI) and your current rent. Move that extra amount into a separate savings account every month for three to six months. If you do not miss it, your target number is realistic. If you find yourself dipping into the account or feeling tight, you need to adjust your budget downward. This exercise also builds your savings, which strengthens your down payment or cash reserves. For example, if your rent is $1,400 and your estimated mortgage payment is $2,100, transfer $700 per month into savings. After three months, you will know whether $2,100 per month is comfortable — and you will have saved $2,100 toward your home purchase. This is the most honest answer to how much house you can afford: the amount where your lifestyle does not suffer.
Common Mistakes That Lead to Buying Too Much House
The most common mistake is using gross income instead of take-home pay when mentally budgeting. Your gross income might be $6,000, but after taxes, retirement contributions, and health insurance, your take-home might be $4,500. A $1,680 mortgage payment is 28% of gross but 37% of take-home — and take-home is what actually hits your bank account. Another mistake is ignoring future expenses. If you plan to have children, change careers, go back to school, or start a business in the next five years, your expenses will increase and possibly your income will temporarily decrease. Build that into your calculation now. A third mistake many buyers make in 2026 is assuming rates will drop and they will refinance soon. While rates may decrease, there is no guarantee of when or by how much — base your purchase on today's rates. Finally, do not confuse the interest rate you are quoted today with a permanent rate if you are considering an adjustable-rate mortgage. ARMs can reset significantly higher, and your affordable payment today could become unaffordable in five to seven years.
Putting It All Together: Your Home Affordability Formula
Here is a step-by-step process to find your number. Step one: calculate your gross monthly income (before taxes). Step two: multiply by 0.28 — this is your maximum housing payment under the front-end ratio. Step three: add up all your existing monthly debt payments. Step four: multiply your gross monthly income by 0.36 and subtract your existing debts — this is your maximum housing payment under the back-end ratio. Step five: take the lower of the two numbers from steps two and four. Step six: subtract estimated property taxes (check your target area), homeowner's insurance, PMI if applicable, and HOA fees. What remains is the amount available for your actual mortgage principal and interest payment. Step seven: use a mortgage payment calculator to reverse-engineer the loan amount that produces that monthly payment at current interest rates. That loan amount, plus your down payment, equals your realistic purchase price.

Frequently Asked Questions
How much house can I afford on a $75,000 salary?
On a $75,000 annual salary with minimal existing debt and a 6.75% interest rate, the 28/36 rule suggests a maximum monthly housing payment of about $1,750. With 5% down, this supports a purchase price of roughly $290,000 to $310,000. Every $300 per month in existing debt reduces your purchase power by approximately $45,000 to $50,000.
What is the 28/36 rule for buying a house?
The 28/36 rule is the most widely used affordability guideline in mortgage lending. It states that your total housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income, and your total debt payments including housing should not exceed 36% of your gross monthly income. Lenders use this to determine how much mortgage you qualify for.
How much house can I afford with an FHA loan?
FHA loans allow higher debt-to-income ratios than conventional loans — up to 57% in some cases compared to the typical 43% to 45% limit for conventional loans. This means you may qualify for a higher purchase price with FHA. However, FHA loans require mortgage insurance for the life of the loan, which adds to your monthly costs. A lower down payment (3.5% minimum) also means a larger loan and higher monthly payment.
