How Much Mortgage Can I Afford? A 2026 Buyer's Guide

Last Checked and Updated on September, 2026

If you're starting to look at homes, "how much mortgage can I afford" is probably the first question on your mind, and honestly, it's the right one to ask before the third one. I've spent years reviewing mortgage content and talking with loan officers about how they actually evaluate buyers, and the gap between what people think they can afford and what a lender will approve catches almost everyone off guard at least once. This guide walks through the terms, the math, and the tools that get you to a number you can trust, not just a guess.

Quick answer: Most lenders start with the 28/36 rule: keep your housing payment at or below 28% of your gross monthly income, and your total debt payments at or below 36%. On a $90,000 salary, that's roughly $2,100 a month for housing. From there, your exact loan amount depends on your down payment, interest rate, credit score, and the loan program you choose.

What Determines How Much Mortgage You Can Afford

Your mortgage affordability comes down to a handful of moving parts: income, existing debt, credit score, cash on hand for a down payment and closing costs, and current interest rates. Lenders weigh all of these together rather than looking at any single number in isolation. A high salary with heavy debt won't get you as far as a moderate salary with a clean debt profile.

The trick is finding the sweet spot between qualifying for the loan amount you want and keeping payments comfortable enough that you're not house-poor. Percentage-based guidelines like the 28/36 rule are a solid starting point, but final underwriting always comes down to documented income, credit history, verified assets, and your debt-to-income ratio.

The 28/36 Rule, and What Else Lenders Use

The 28/36 rule is the most common shorthand in the industry: spend no more than 28% of your gross monthly income on housing costs (principal, interest, property tax, and insurance, often shortened to PITI), and no more than 36% on total monthly debt, including that housing payment plus car loans, student loans, and credit cards.

It's a useful benchmark, but it's not the only one. Some advisors use a simpler income-multiple rule of thumb instead, suggesting a home price around 2.5 to 3 times your annual gross income. Neither rule accounts for your specific interest rate, local taxes, or down payment size, so treat them as a starting range rather than a final answer. If you want a number built around your actual numbers instead of a rule of thumb, that's exactly what a lender's calculator or a conversation with a loan officer is for.

Total Homeownership Costs Go Beyond the Mortgage

The mortgage payment is only part of the budget. Property taxes, homeowners insurance, routine maintenance, utilities, and possibly HOA dues all add up. A widely used planning figure sets aside about 1% of a home's purchase price each year for maintenance, though some advisors recommend closer to 2% for older properties. Closing costs and prepaid taxes add another upfront expense, so it helps to plan for those separately from your down payment.

Mortgage Terms Worth Knowing Before You Start

A few terms show up constantly in affordability conversations. Here's what they actually mean.

Debt-to-income ratio (DTI) is your total monthly debt payments divided by your gross monthly income. For years, the industry treated 43% as the hard ceiling for a "qualified mortgage." That changed in 2021, when the Consumer Financial Protection Bureau replaced the strict 43% DTI cap with a pricing-based test tied to how a loan's rate compares to the average prime offer rate. In practice, most lenders and loan programs still use DTI limits somewhere between 43% and 50% as a working guideline, even though it's no longer a strict federal rule. A lower DTI generally means better approval odds and better pricing.

Annual household income covers all regular pre-tax income: salary, wages, bonuses, and stable rental income. Lenders verify this with pay stubs, W-2s, and tax returns. If you're self-employed, expect to provide profit-and-loss statements and two years of business tax returns, since documentation requirements vary by program.

Monthly debt means contractual, recurring payments: minimum credit card payments, auto loans, student loans, and child support. Utilities and groceries don't count toward DTI, even though they're real monthly costs.

Available funds refers to documented cash for your down payment, closing costs, and reserves. Lenders will ask where the money came from, and large or unusual deposits often need a paper trail.

Down payment requirements vary a lot by loan type. FHA loans allow as little as 3.5% down for borrowers with qualifying credit. Some conventional programs go as low as 3% down for eligible first-time buyers. A larger down payment reduces or eliminates private mortgage insurance and lowers your monthly principal and interest.

Closing costs typically run about 2% to 5% of the loan amount, occasionally closer to 6% depending on your state and lender, according to Fannie Mae. These cover the appraisal, title insurance, recording fees, and escrow setup. Some of these can be negotiated or paid by the seller.

Credit score affects both approval and pricing. Many conventional loans use 620 as a practical baseline, while scores above 700 generally unlock better rates. FHA, VA, and USDA loans each have their own credit flexibility, so it's worth checking program-specific minimums rather than assuming one number applies everywhere.

Mortgage rate moves with market conditions, your credit profile, loan term, and program type. Even a quarter-point difference changes your monthly payment and total interest by a meaningful amount over 30 years, so it's worth shopping more than one lender before locking.

Monthly mortgage payment usually means PITI, principal, interest, taxes, and insurance, plus PMI if your down payment is under 20% and any HOA dues. Taxes and insurance can shift year to year, which changes your escrowed payment even after your rate is locked.

Annual property tax is set locally, so it varies widely by county and by your home's assessed value. Reassessments can quietly push your housing costs up even if your mortgage rate never changes.

APR stands for annual percentage rate, and it bundles your interest rate with certain loan fees to give a fuller picture of borrowing cost. It's a better tool for comparing offers side by side than the interest rate alone.

What Actually Moves the Needle on Your Affordability

Employment stability and consistent, documented income carry a lot of weight, often more than buyers expect. Your credit profile, the loan program you choose, local home prices and taxes, your cash reserves, and current interest rates all factor in too. Lenders also look at the pattern behind your numbers, not just the totals: a long, steady payment history tends to matter as much as the raw DTI figure. Some programs allow compensating factors, so larger reserves or a bigger down payment can help a borrower who's borderline on paper.

How to Calculate How Much Mortgage You Can Afford

There's more than one way to land on a real number, from a quick manual formula to full online calculators.

Method 1: Estimate Affordability Based on Your Income

Start with a simple formula: multiply your gross monthly income by 0.28 to get your target maximum housing payment. Then subtract estimated taxes, insurance, and PMI to see what's left for principal and interest.

For example, on a gross monthly income of $8,000, the math looks like this: $8,000 × 0.28 = $2,240 maximum housing payment. If taxes and insurance run about $400 a month, roughly $1,840 is available for principal and interest. This gives you a quick screen based on your income alone, not a final approval, since actual qualification depends on full underwriting and your complete DTI picture.

Method 2: Fannie Mae's Mortgage Affordability Calculator

Fannie Mae's calculator factors in your gross income, car payments, credit card debt, other obligations, down payment, and interest rate to produce a more complete purchase estimate. It's a solid option for scenario planning, especially if you want to see how changing your down payment shifts your buying power.

Method 3: NerdWallet's How Much House Can I Afford Calculator

NerdWallet's tool adds annual pretax income, monthly debt, recurring expenses, and loan details like term and down payment, so you can see how each variable changes your purchasing power. It's useful for quick side-by-side comparisons.

Method 4: Bank Calculators (like US Bank)

Most major banks offer their own affordability calculators that apply standard front-end and back-end ratios along with local rate data to estimate a prequalification range. These are handy for a lender-specific estimate, though different banks apply slightly different overlays on top of the standard rules.

Method 5: Talk to an AI Loan Officer Assistant

Calculators are useful, but they all share the same limitation: they hand you a number and stop there. Bluerate's AI Loan Officer Assistant takes a different approach. Instead of a static form, it asks about your situation one question at a time, starting with your target location, then loan purpose, property type, income and employment, your available funds, and your credit range.

Once it has a full picture, it matches you with real loan officers who actually handle your loan type, whether that's conventional, FHA, VA, USDA, or Non-QM, and ranks them by fit rather than just showing a generic rate. That matters because the rate a calculator estimates and the rate you're actually offered at closing are often two different numbers. Going straight to a loan officer who specializes in your situation tends to close that gap faster than running the same numbers through five different calculators. It's free to use and works in English, Chinese, and Spanish, so it's a solid first stop whether you're comparing scenarios or ready to start talking to someone.

Mortgage Affordability vs. Mortgage Capacity

These two terms get used interchangeably, but they're not the same thing. Mortgage capacity is the maximum amount a lender is technically willing to approve based on your income, debt, and credit. Mortgage affordability is the amount that still leaves you comfortable month to month, with room for savings, emergencies, and everything else in life that isn't your mortgage.

It's entirely possible to be approved for more than you'd actually want to pay. Lenders are measuring risk, not your personal comfort level, so the final call on what to actually borrow is yours to make, not theirs.

Types of Mortgage Loans and How They Differ

Loan programs vary in their down payment minimums, credit requirements, and loan limits, so it's worth understanding the basics before you pick one.

| Loan Type | Typical Minimum Down Payment | Typical Minimum Credit Score | 2026 Loan Limit (Most Areas) | 2026 Loan Limit (High-Cost Areas) | |---|---|---|---|---| | Conventional (conforming) | 3%–5% | 620 | $832,750 | $1,249,125 | | FHA | 3.5% | 580 | $541,287 | $1,249,125 | | VA | 0% for eligible veterans | Varies by lender | Follows conforming limits | Follows conforming limits | | USDA | 0% for eligible rural buyers | Varies by lender | Program-specific | Program-specific | | Jumbo | Typically 10%–20% | 680–700+ | Above conforming limits | Above conforming limits |

The conforming loan limit set by the Federal Housing Finance Agency rose to $832,750 for most of the country in 2026, with a ceiling of $1,249,125 in high-cost areas. Anything above that generally moves you into jumbo loan territory, which comes with stricter credit and reserve requirements. FHA's own limits moved up alongside the conforming limit, ranging from a floor of $541,287 in lower-cost counties to the same $1,249,125 ceiling in expensive ones. If you're not sure which bucket your target home falls into, your county's specific limit is worth checking before you start touring properties.

How to Qualify for a Mortgage

Qualifying comes down to documentation: income, assets, employment history, and an acceptable credit profile. Preapproval typically involves a credit check and a review of your paperwork, and it results in a conditional letter stating your estimated loan amount, which is genuinely useful when you're making offers. Final approval still depends on the property appraisal, a clean title, and your financial picture staying roughly the same between preapproval and closing, so it's not the moment to open a new credit card or change jobs.

Frequently Asked Questions About Mortgage Affordability

Can I afford a $500,000 house on a $200,000 salary?

Possibly, and the details matter more than the headline numbers. Here's a walk-through: a $200,000 annual salary works out to roughly $16,667 a month. Under the 28% rule, that puts your maximum housing payment around $4,667. On a $500,000 home with 20% down ($100,000), you'd be financing $400,000. At a 6.75% rate on a 30-year fixed loan, principal and interest on that amount comes to roughly $2,595 a month, leaving about $2,072 for taxes, insurance, PMI, and HOA before you hit the 28% ceiling.

If your local property taxes and insurance run higher than that, the math gets tighter. You'll also want to check your back-end DTI, since total monthly debt including the mortgage should generally stay near or below 36% to 43%, depending on the loan program. In most markets, a $500,000 home on a $200,000 income is workable with 20% down and manageable existing debt, though high-tax areas or heavier monthly obligations can change that picture.

How much house can I buy on a $200,000 income?

There's no single right answer here, since it depends on your down payment, local taxes, current rates, and other monthly debt. As a very rough planning range, households at this income level with moderate debt often land somewhere between $600,000 and $900,000, but that band is wide enough that it's really just a starting point. Running your actual numbers through a calculator, or talking to a loan officer directly, will get you a far more useful figure.

What's the monthly payment on a $200,000 mortgage?

It depends entirely on your rate and term. Using standard amortization on a 30-year fixed loan, a 7.25% rate works out to roughly $1,364 a month in principal and interest, while a 6.75% rate comes to about $1,297. Both figures cover principal and interest only, so add your taxes, insurance, and any PMI or HOA dues for the full monthly housing cost.

What salary do I need to afford a $300,000 house?

Using the 28% rule as a guide: if total housing costs on a $300,000 home with 20% down come to around $2,000 a month, multiplying that by roughly 3.6 to 4.0 gives a rough gross annual income in the $75,000 to $100,000 range, depending on local taxes, insurance, and your other debt. It's a helpful ballpark, not a guarantee, since your exact down payment and rate will move the number in either direction.

How much can I borrow before I need a jumbo loan?

In most of the country, you can borrow up to $832,750 through a conventional conforming loan before moving into jumbo territory, and up to $1,249,125 in officially designated high-cost counties. Jumbo loans, which cover anything above those limits, typically come with stricter credit score requirements, larger down payments, and more cash reserves in the underwriting file, so it's worth confirming your county's specific limit before assuming you'll need one.

How do lenders actually calculate affordability?

Lenders start with your gross income and back out your existing debt to land on a maximum monthly payment, using front-end and back-end DTI ratios as guardrails. From there, they layer in your credit profile, the size of your down payment, your cash reserves, and the specific loan program's rules, since FHA, VA, USDA, and conventional loans each apply slightly different standards. The number you see on a calculator is a solid estimate, but full underwriting always digs deeper into your documentation before issuing a final approval.

The Bottom Line

Affordability comes down to income, debt, credit, down payment, local taxes and insurance, and where rates sit when you're ready to buy. The 28/36 rule is a reasonable starting point, but running your actual numbers through a calculator, or better yet, through a real conversation with a loan officer, gets you a figure you can actually plan around.

Every situation is different enough that generic rules only get you so far. If you want a next step that goes beyond a number on a screen, you can chat with Bluerate's AI Loan Officer Assistant to get matched with a loan officer who fits your loan type, or head straight to personalized rates to see where you stand. Always confirm program-specific rules with your loan officer, and check with a tax professional about how local deductions might affect your numbers.
