How Much House Can I Afford? 2026

How Much House Can You Really Afford?

Buying a home is the largest financial commitment most Americans will ever make, and getting the number right matters more than almost any other money decision in your life. The question is deceptively simple on the surface. You earn a certain salary, you have a certain amount saved for a down payment, and interest rates sit at whatever level the market dictates today. But the real answer to how much house you can afford depends on a web of interconnected factors that go far beyond a single mortgage payment calculation. Understanding these factors before you start house hunting can save you from years of financial stress or, on the flip side, from unnecessarily limiting yourself in a competitive market.

The 28/36 Rule and Why Lenders Still Rely on It

The 28/36 rule has been the gold standard for housing affordability guidance for decades, and despite all the changes in the lending industry, it remains the starting point for virtually every mortgage conversation. The first number, 28, means that your total monthly housing costs should not exceed 28 percent of your gross monthly income. Housing costs in this context include your mortgage principal and interest payment, property taxes, homeowners insurance, and any homeowners association fees. The second number, 36, means that your total monthly debt obligations, including your housing costs plus all other recurring debts like car loans, student loans, credit card minimum payments, and personal loans, should not exceed 36 percent of your gross monthly income.

For someone earning $80,000 per year, this translates to a maximum of roughly $1,867 per month on housing costs under the 28 percent threshold, and a maximum of $2,400 per month across all debts under the 36 percent threshold. If you already carry $500 per month in student loan and car payments, the 36 percent rule effectively caps your housing at $1,900 per month, which is close to the 28 percent limit anyway. The interplay between these two numbers is where the real constraint often sits, and it is exactly why existing debt has such a powerful impact on how much home you can purchase.

It is worth noting that the 28/36 rule is a guideline, not a law. Some lenders, particularly those offering FHA loans, will approve borrowers with debt-to-income ratios as high as 43 or even 50 percent on the back end. But just because a lender will approve you at those levels does not mean you should borrow that much. Living at the edge of your borrowing capacity leaves no room for unexpected expenses, job disruptions, or interest rate changes if you have an adjustable rate mortgage. Many financial planners actually recommend keeping your housing costs closer to 25 percent of gross income if you want genuine financial breathing room.

How Lenders Determine How Much You Can Borrow

When you apply for a mortgage, the lender evaluates your application through several lenses simultaneously. Your credit score is the first gate. Conventional loans typically require a minimum score of 620, while FHA loans may accept scores as low as 580 with a 3.5 percent down payment. Your credit score does not just determine whether you qualify; it directly affects the interest rate you receive, and even a half-point difference in rate can shift your purchasing power by tens of thousands of dollars over the life of a 30-year loan.

Income verification is the next major piece. Lenders want to see stable, documented income, which usually means two years of tax returns, recent pay stubs, and W-2 forms. If you are self-employed, the documentation burden increases significantly, and lenders will typically average your income over two years, which can be a problem if your earnings have fluctuated. They also look at your employment history for consistency. Frequent job changes, even lateral ones within the same industry, can raise concerns during underwriting.

Your existing debts feed directly into the DTI calculation discussed above, but lenders also examine the nature of those debts. Revolving debt like credit cards is viewed differently from installment debt like a car loan with a fixed end date. If a car loan has fewer than ten payments remaining, some lenders will exclude it from the DTI calculation entirely because it will be paid off shortly after you move into the home. This is the kind of nuance that can shift your approval amount by a meaningful margin, and it is one reason working with a knowledgeable loan officer or mortgage calculator early in the process pays dividends.

The Relationship Between Income and Home Price

A common rule of thumb suggests that you can afford a home priced at roughly three to four times your annual gross income. On a household income of $100,000, that puts the range at $300,000 to $400,000. This heuristic worked reasonably well for decades when mortgage rates hovered between 4 and 6 percent, but it breaks down in environments where rates move significantly in either direction. When rates dropped below 3 percent in 2020 and 2021, borrowers could comfortably stretch to 4.5 or 5 times income. Now that rates have climbed back toward the 6 to 7 percent range, the realistic multiple for many buyers has compressed back toward 3 times income or even lower.

The income-to-home-price relationship also depends heavily on your down payment. A buyer putting 20 percent down on a $400,000 home borrows $320,000, while a buyer putting 5 percent down borrows $380,000. That $60,000 difference translates to roughly $400 more per month at current rates, which could push the lower-down-payment buyer past their DTI threshold. Additionally, the buyer with less than 20 percent down will pay private mortgage insurance, which typically adds another $100 to $300 per month depending on the loan size and credit score.

Why Mortgage Pre-Approval Matters More Than You Think

Getting pre-approved for a mortgage before you start shopping is not just a nice-to-have step; in most competitive markets, it is essentially mandatory. Pre-approval involves a lender pulling your credit, verifying your income and assets, and issuing a letter stating the loan amount they are willing to extend. This differs from pre-qualification, which is a rough estimate based on self-reported information and carries little weight with sellers.

From the seller's perspective, a pre-approval letter signals that your offer is serious and financially backed. In a multiple-offer situation, sellers will often choose a pre-approved buyer over one who has not taken that step, even if the pre-approved buyer's offer is slightly lower. The pre-approval also protects you as the buyer by establishing a firm budget ceiling, which prevents the emotional trap of falling in love with a home that stretches your finances to the breaking point.

Pre-approval letters are typically valid for 60 to 90 days, and the rate quoted is not always locked in for that entire period. If rates move during your search, your purchasing power may shift. Some lenders offer rate locks at the pre-approval stage for a fee, which can be worthwhile in a rising rate environment. Be aware that the hard credit inquiry from a pre-approval may temporarily lower your credit score by a few points, but multiple mortgage inquiries within a 14 to 45 day window, depending on the scoring model, count as a single inquiry, so shopping among several lenders is actually encouraged.

Hidden Costs of Homeownership Beyond the Mortgage Payment

One of the most common mistakes first-time homebuyers make is budgeting only for the mortgage payment while ignoring the substantial additional costs that come with owning a home. Property taxes alone can add hundreds of dollars per month to your housing costs, and they tend to increase over time as local governments reassess property values. You can estimate these costs using our property tax calculator to get a clearer picture for any state or county. Homeowners insurance is another unavoidable expense, and rates have been rising sharply in many states due to increased natural disaster risk and rising construction costs.

Maintenance and repairs are the sleeper cost that catches many new homeowners off guard. The general recommendation is to budget 1 to 2 percent of your home's value per year for ongoing maintenance. On a $400,000 home, that means setting aside $4,000 to $8,000 annually for things like roof repairs, HVAC maintenance, plumbing issues, and appliance replacements. Unlike renting, where a landlord covers these costs, homeownership puts you on the hook for every broken water heater and leaking roof. If you buy an older home, these costs can be considerably higher during the first few years as deferred maintenance issues surface.

Utility costs also tend to be higher for homeowners than renters because homes are generally larger than rental apartments. HOA fees, if applicable, can range from $100 to over $500 per month and typically increase over time. And do not forget closing costs, which run 2 to 5 percent of the purchase price and are due at the time of sale. On a $400,000 home, closing costs could run $8,000 to $20,000, a sum that comes on top of your down payment and must be accounted for in your savings plan.

How Student Loans Affect Your Mortgage Qualification

Student loan debt is one of the most significant barriers to homeownership for younger Americans, and the way lenders treat this debt in mortgage calculations can be confusing. For borrowers on income-driven repayment plans where the monthly payment might be as low as zero dollars, conventional loan guidelines typically use either the actual payment amount or 0.5 to 1 percent of the outstanding loan balance, whichever is greater, for DTI purposes. This means that a borrower with $80,000 in student loans on a zero-dollar IDR payment might still have $400 to $800 counted against their monthly debt obligations.

FHA loans have their own rules. If the student loan payment reported on the credit report is zero, FHA lenders must use 0.5 percent of the outstanding balance as the assumed monthly payment. This can dramatically reduce the mortgage amount you qualify for. A borrower earning $75,000 per year with $100,000 in student loans would see $500 per month counted against their DTI before even factoring in any other debts, which eats directly into the mortgage payment they can support.

The strategic implications are significant. Paying down student loan balances before applying for a mortgage can expand your purchasing power more than almost any other financial move. Alternatively, refinancing student loans to lower the monthly payment, even if the total interest paid increases, can improve your DTI ratio and mortgage qualification in the short term. These are tradeoffs worth modeling carefully with tools like our debt consolidation calculator before making a decision.

Affordability Varies Dramatically Across US Markets

The national median home price tells only a fraction of the story because housing affordability in the United States varies enormously from one metro area to the next. A household earning $100,000 can comfortably purchase a spacious four-bedroom home in markets like Indianapolis, Memphis, or Cleveland, where median prices sit in the $200,000 to $250,000 range. That same income in San Francisco, where the median home price exceeds $1.2 million, would not even qualify for a starter condo without a massive down payment.

The divergence in affordability has accelerated since 2020, driven by remote work migration patterns that sent waves of higher-income coastal workers into previously affordable midsize cities. Markets like Boise, Austin, Nashville, and Raleigh saw enormous price increases as demand outstripped supply. At the same time, some previously expensive markets like San Francisco and New York saw temporary price softening as residents departed, though prices in these cities have since stabilized or resumed climbing.

When evaluating affordability in a new market, it is not enough to compare home prices alone. You must also consider property tax rates, which vary from under 0.5 percent in Hawaii to over 2 percent in New Jersey and Illinois. State income tax differences can shift your take-home pay by thousands of dollars per year. Insurance costs, which have spiked in states prone to hurricanes, wildfires, and flooding, can add significantly to the total cost of homeownership. And of course, the overall cost of living in a new city affects how much of your income remains available for housing after covering food, transportation, healthcare, and other necessities.

The bottom line is that mortgage affordability is not a single number but a range shaped by your income, debts, credit profile, local market conditions, and personal risk tolerance. Taking the time to understand each of these variables before committing to a purchase price will help you buy a home that enhances your financial life rather than one that becomes a source of ongoing stress.
