How Much House Can I Afford? A 2026 Affordability Guide

Buying a home is the biggest financial decision most people ever make — and the question "how much house can I afford?" carries far more weight than it first appears. Your salary is only part of the answer. Interest rates, property taxes, homeowners insurance, existing debts, down payment size, and the gap between what a lender will approve you for and what you can actually live with all shape the real number. This guide walks through the exact math lenders use in 2026, shows real affordability figures by income level, and explains the difference between qualifying for a mortgage and being comfortable with one.

How Much House Can I Afford?

A safe estimate is that you can afford a home priced at roughly 3 to 4 times your gross annual income, provided your total monthly housing costs stay under 28% of gross monthly income and your total debts stay under 36%. At today's average 30-year rate of about 6.58% with 20% down, a household earning $100,000 can comfortably afford a home priced around $335,000 to $380,000. Recalculate your number whenever rates move by more than 0.25%, and always leave a 10–15% cushion below whatever a lender approves.

Why "You Can Afford X" Answers Are Almost Always Wrong

Two households earning the same $120,000 per year can have wildly different home-buying power. One has $600 in car and student loan payments; the other is debt-free. One lives in a state with 2.2% property tax; the other in a state with 0.7%. One has 20% saved for a down payment; the other has 5%. All four of these differences move the affordable home price by tens of thousands of dollars — and none of them are captured by a generic "3× your salary" rule.

The starting point for any sensible home affordability calculation is your personal debt-to-income ratio, not a rule of thumb. Once you know it, everything else — your maximum monthly payment, your target home price, your down payment goal — falls into place as arithmetic.

The 28/36 Rule: The Foundation of Home Affordability

Every mortgage affordability calculation starts here. The 28/36 rule is the benchmark lenders have used for decades, and it remains the single most important formula for figuring out how much house you can afford in 2026.

RatioWhat It CoversCapWhy It Matters
Front-End DTIMonthly PITI only (principal, interest, taxes, insurance)28%Protects you from housing eating your paycheck
Back-End DTIPITI + all other monthly debts (car, student, credit card, personal loans)36%Ensures total debt load stays manageable

Worked Example

Household earning $8,000/month gross, with $600 in other debts

28% front-end cap: $8,000 × 0.28 = $2,240 max PITI
36% back-end cap: $8,000 × 0.36 = $2,880 total debts
After subtracting $600 in other debts: $2,880 − $600 = $2,280
Max monthly housing payment: $2,240 (lower of the two)

Whichever ratio produces the smaller number becomes your ceiling. If you have no other debts, the 28% rule almost always sets the cap.

Why this rule still matters in 2026: Lenders will often approve back-end DTIs up to 45% for conventional loans, 57% for FHA, and up to 60% for VA. But approval is not affordability. The 28/36 rule protects you from becoming "house poor" — the situation where you own a beautiful home but cannot afford vacations, savings, or emergencies.

Today's Mortgage Rates and Why They Change What You Can Afford

As of late July 2026, the average 30-year fixed mortgage rate is hovering around 6.58%, with the 15-year fixed near 5.96%. Rates have sat in the 6% range throughout 2026, and Fannie Mae's latest forecast projects they'll stay near 6.4% through year-end.

A single percentage point on your mortgage rate changes what you can afford by tens of thousands of dollars. Here is what the same $500,000 loan looks like at three different rates:

Interest RateMonthly P&ITotal Interest (30 yrs)Payment vs. 5%
5.00%$2,684$466,278Baseline
6.58%$3,185$646,530+$501/mo
7.50%$3,496$758,772+$812/mo

That $501 monthly gap between 5% and 6.58% is real money. At a 28% housing ratio, you need to earn about $21,500 more per year to afford the same house at today's rates than you would have at 5%. This is exactly why running the numbers through a home mortgage calculator with current rates matters — old rules of thumb from the 2010s no longer apply cleanly.

What Your Monthly Mortgage Payment Actually Includes (PITI)

When people say "mortgage payment," they usually mean just principal and interest. But your real monthly obligation is bigger. Lenders calculate affordability using PITI:

THE FOUR COMPONENTS OF PITI

P — Principal: portion that reduces the loan balance
I — Interest: cost of borrowing, based on the remaining balance
T — Taxes: property taxes, typically 1–2.5% of home value per year
I — Insurance: homeowners insurance + PMI (if down payment under 20%)

Skip PITI and your affordability estimate will be off by hundreds of dollars a month. On a $400,000 home in a state like New Jersey with a 2.2% property tax rate, you're looking at roughly $733 per month in property taxes alone. In Tennessee, at 0.7%, the same home costs about $233 a month in taxes — a $500 gap that translates to about $85,000 in affordable home price at today's rates.

How Much House Can You Afford By Income? Real 2026 Numbers

This is the table most homebuyers actually want to see. All numbers assume a 30-year fixed mortgage at 6.58%, 20% down, 1.25% property tax, 0.35% insurance, and no existing debts. Numbers get smaller if you have car loans, student loans, or a smaller down payment.

Annual IncomeMax PITI (28%)Comfortable Home PriceStretched Home Price
$50,000$1,167$165,000$210,000
$75,000$1,750$250,000$315,000
$100,000$2,333$335,000$420,000
$125,000$2,917$420,000$525,000
$150,000$3,500$500,000$630,000
$200,000$4,667$670,000$835,000
$250,000$5,833$835,000$1,050,000

Estimates only. Run the exact calculation using our home mortgage calculator for your specific numbers.

The "comfortable" column applies the 28% front-end rule. The "stretched" column pushes to 35%, which most lenders will approve for buyers with solid credit and no other debt. Just because you can borrow that much doesn't mean you should — stretched numbers leave little room for savings, emergencies, or lifestyle spending.

Mortgage affordability, PITI, and DTI ratios explained

Down Payment: The Lever That Changes Everything

Your down payment does two things: it lowers the amount you need to borrow, and it can eliminate Private Mortgage Insurance (PMI). PMI is required on conventional loans when you put down less than 20%, typically costing between 0.3% and 1.5% of your loan amount per year.

Loan TypeMin. DownPMI Required?Best For
Conventional3–5%Yes, below 20%Credit 680+, plans to reach 20% equity
FHA3.5%Yes, life of loanCredit 580–680, higher DTI
VA0%No PMIVeterans and active-duty military
USDA0%Yes (guarantee fee)Rural and eligible suburban areas
Conventional 20%20%No PMIBuyers with substantial savings

Loan Programs and Their DTI Limits in 2026

Not all mortgages have the same debt-to-income limits. If your DTI is on the higher side, the loan program you choose can be the difference between approval and denial.

Loan TypeStandard DTI CapMax DTI (with compensating factors)
Conventional (Fannie/Freddie)43%Up to 50%
FHA43%Up to 57%
VA41%Up to 60%
USDA41%Up to 46%
Jumbo43%Up to 45%

"Compensating factors" usually means a credit score of 720 or higher, substantial cash reserves (typically 3 to 6 months of PITI in the bank), a large down payment, or a very stable employment history. Without them, expect lenders to hold you closer to the standard cap.

One more thing to know: 2026's conforming loan limit — the maximum for a standard conventional loan — is $832,750 in most U.S. areas. Anything above that is a jumbo loan, which comes with slightly higher rates and stricter requirements.

The Hidden Costs of Homeownership Most Buyers Underestimate

PITI is not the whole picture. Once you close, a stack of new expenses lands on your plate that renters never had to think about. Budget for these before you decide how much home to buy:

1. Maintenance and repairs

The widely used rule of thumb is 1% to 3% of home value per year. On a $400,000 home, that's $4,000 to $12,000 annually — often front-loaded in the first year for surprises.

2. HOA fees

In condos and planned communities, expect $200 to $600 per month, sometimes much more. HOA fees count toward your DTI and reduce how much house you can qualify for.

3. Utilities

Most homes use two to three times the energy of a similar-sized apartment. Factor in bigger electric, gas, water, and trash bills — often $200 to $400 more per month than renting.

4. Closing costs

Typically 2% to 5% of the loan amount, paid at closing. On a $400,000 mortgage, that's $8,000 to $20,000 out of pocket — separate from your down payment.

5. Moving and setup

Furniture, appliances, window coverings, yard equipment, and everything else. Easily $5,000 to $15,000 in the first year alone.

6. Insurance surprises

Homeowners insurance has climbed sharply in climate-affected states like Florida, California, Texas, and Louisiana. Always get real quotes before falling in love with a house.

The 30% rule for true monthly cost: A realistic buyer treats homeownership as costing PITI plus about 30% for these extras. On a $2,500 PITI, that's another $750 per month in true monthly cost — the reason so many first-time buyers end up feeling stretched even when their mortgage math looked fine on paper.

How to Actually Use a Mortgage Affordability Calculator

A mortgage calculator turns theory into one clean number — but only if you feed it accurate inputs. Follow this workflow:

1
Start with your gross monthly incomeUse the number before taxes and deductions. If buying with a partner, combine both incomes only if both will be on the mortgage.
2
Add up all recurring monthly debtsInclude car loans, student loans, credit card minimums, personal loans, alimony, and child support. Skip utilities, groceries, subscriptions, and retirement contributions.
3
Enter down payment in dollars, not percentageThis gives you a clearer picture of true purchasing power and matches how lenders think about your cash-to-close.
4
Use the current interest rateDon't plug in the rate you hope for — plug in the rate you'll actually get. As of this week, that's around 6.58% for a 30-year fixed with strong credit.
5
Set property tax to your state's effective rateNational average is about 1.1%, but the range is wide — New Jersey is 2.2%, Hawaii is 0.3%. Use your specific state, not the national average.
6
Use 0.35% for homeowners insuranceA reasonable starting point. For a real number, get a quote in the specific neighborhood you're targeting.
7
Subtract 10–15% from the resulting home priceThat built-in cushion covers rate increases while shopping, unexpected repairs in year one, and closing costs.

Run this in our home mortgage calculator and cross-check the monthly payment with our loan calculator to see how principal and interest change over the life of the loan. If you're a freelancer or self-employed, remember lenders use your net income after business expenses — our freelancer tax calculator helps you estimate the number they'll actually see on your tax returns.

Renting vs. Buying: When Does Buying Actually Make Sense?

Buying isn't always the right move. At 6.58% mortgage rates, the classic "buying is always better than renting" wisdom often falls apart in the first three to five years. Break-even on transaction costs — closing costs plus selling costs down the road — typically takes 5 to 7 years at today's rates.

Buying Makes Sense When...Renting Makes Sense When...
You'll stay in the home for at least 5 yearsYou may move within 3 years for career or family
PITI is within 15% of local rent for a comparable homeLocal rent is significantly cheaper than owning
You have 3–6 months of expenses saved after the down paymentYou'd be stretching to hit the down payment
Your income is stable and career direction is settledYour income is variable or you value flexibility
You want customization and long-term stabilityYou'd rather invest the difference elsewhere

Our rent calculator helps you figure out what you can afford in rent so you can make a fair side-by-side comparison against a mortgage payment.

How to Increase How Much House You Can Afford

If the number from your affordability calculation is smaller than you hoped, you have real levers to pull. In order of impact:

  • Pay down high-payment debts. A $500 car payment paid off equals roughly $80,000 more in home price at today's rates. The biggest lever most buyers ignore.
  • Increase your down payment. Every extra $10,000 down reduces your monthly payment by about $65 at 6.58%, or lets you buy about $12,000 more in home.
  • Improve your credit score. Going from 680 to 760 can cut your rate by 0.25% to 0.5%, saving hundreds a month or letting you afford $30,000 to $60,000 more home.
  • Buy in a lower-tax jurisdiction. Moving from a 2.2% property tax state to a 0.7% state can add $150,000+ to your affordable home price on the same income.
  • Consider a longer-term loan carefully. These lower your monthly payment but cost far more over time. Only use them if you have a clear payoff plan.
  • Add a co-borrower. A spouse, partner, or family member with additional income increases the amount you can qualify for.

One thing not to do: don't stretch to the absolute lender maximum. Every experienced homeowner will tell you the same thing — leaving a cushion is what makes homeownership enjoyable rather than stressful.
