How Much House Can I Afford? Salary-Based Guide for 2026

Bottom line: At today's rates (approximately 7% for a 30-year fixed mortgage), the standard guideline is that you can afford a home priced at 3 to 4 times your annual gross income — if you have minimal existing debt and a 20% down payment. A $75,000 salary affords roughly $225,000–$300,000; a $100,000 salary puts you in the $300,000–$400,000 range. But the real answer depends on five variables: your income, existing monthly debts, down payment, current interest rate, and local property taxes. This guide breaks down every factor and links to our free home affordability calculator so you can model your exact situation in 60 seconds.

Key Takeaways

• The 28/36 rule is the standard mortgage guideline: keep housing costs below 28% and total debt below 36% of gross monthly income.

• At 7% interest with 20% down, a rough estimate is: home price ≈ annual salary × 3.5.

• Every 1% rise in mortgage rates reduces buying power by roughly 10% — a $400,000 budget at 6% shrinks to about $365,000 at 7%.

• Existing monthly debts (car payments, student loans, credit cards) directly reduce the mortgage you qualify for.

• A 760+ credit score vs. 680 can save $50–$100 per month on a $350,000 loan.

The 28/36 Rule: The Industry Standard for Mortgage Qualification

The mortgage industry uses two ratios — front-end and back-end debt-to-income (DTI) ratios — to determine how much house you can qualify for:

Front-end ratio (housing ratio): Monthly housing costs should not exceed 28% of gross monthly income. Housing costs include principal, interest, property taxes, and homeowners insurance — collectively called PITI. Mandatory HOA dues count too.

Back-end ratio (total DTI): Total monthly debt payments should not exceed 36%–43% of gross monthly income. This includes PITI plus all other recurring debts: car loans, student loans, minimum credit card payments, personal loans, child support, and alimony. Conventional loans target 36%–43%; FHA loans allow up to 57% with compensating factors.

These are Fannie Mae and Freddie Mac guidelines — the two government-sponsored enterprises that buy most conventional mortgages from lenders. Because lenders want to sell their loans into the secondary market, they follow these rules closely.

Example: You earn $100,000 per year ($8,333 gross monthly). Maximum PITI at 28% = $8,333 × 0.28 = $2,333 per month. If you also have $400/month in car and student loan payments, your back-end limit is $8,333 × 0.36 = $3,000; subtracting $400 leaves $2,600 for housing — still above the $2,333 front-end cap, so the front-end rule is the binding constraint in this case.

How Much House Can I Afford by Salary?

The table below estimates the maximum home price for each income level using the 28% front-end guideline, a 30-year fixed mortgage at 7% interest, 20% down payment, estimated property taxes (1.1% annually), and homeowners insurance ($150/month). These figures assume no other monthly debt — car loans, student loans, or credit card debt will reduce your maximum home price.

Assumptions: 30-year fixed at 7.0%, 20% down, property tax 1.1%/year, homeowners insurance $150/month, no existing monthly debt. Actual numbers vary significantly by location. Use the affordability calculator for your specific inputs.

How to adjust from this table:

• Lower the estimate if you carry significant monthly debts (car payment, student loans, credit cards)

• Lower the estimate if your property taxes exceed 1.5% (common in Illinois, New Jersey, and Texas)

• Raise the estimate if you are putting down more than 20%

• Raise the estimate slightly if you have a 740+ credit score and secure a rate below 7%

How Much Does the Mortgage Rate Change What You Can Afford?

Interest rates have an enormous impact on buying power — more than most first-time buyers expect. Here is the same $100,000 salary scenario at different mortgage rates:

Max P&I = $2,333 PITI limit − $300 estimated taxes − $150 insurance = $1,883 available for principal and interest.

Moving from 6% to 7% reduces buying power by approximately $39,000 on a $100,000 salary. A full percentage-point shift costs roughly $42,000 in home buying capacity. This is why rate-shopping matters: within a 45-day window, FICO treats all mortgage credit pulls as a single inquiry, so getting quotes from 3–5 lenders costs no extra credit impact but can save 0.25%–0.5% on your rate. On a $300,000 loan, 0.25% lower means $50/month saved — $18,000 over 30 years. See our guide on getting pre-approved for how to approach the lender comparison process efficiently.

Down Payment: How It Affects Your Budget

Your down payment affects affordability two ways: it reduces the loan size (lowering your monthly payment), and if you put down less than 20%, it adds private mortgage insurance (PMI) — typically 0.5%–1.5% of the loan per year — which further reduces what you can afford.

Estimated at 7% rate, $350,000 purchase price, property tax $4,200/yr, homeowners insurance $150/mo. PMI estimated at 0.75% of loan annually.

The PMI impact: Buying with 10% down instead of 20% adds $197/month in PMI on a $350,000 home — $2,364 per year. PMI cancels automatically once you reach 20% equity under the Homeowners Protection Act, so it is not permanent. For buyers with solid income but limited savings, a smaller down payment can be the right choice — particularly with assistance programs. See our first-time homebuyer programs guide for programs covering 3%–5% of the purchase price in most states.

The full upfront cost also includes closing costs of 2%–5% of the purchase price ($7,000–$17,500 on a $350,000 home), which must typically come from separate funds. Budget for both your down payment and closing costs before settling on your target home price.

The Full Monthly Cost of Homeownership: Beyond PITI

The 28% rule covers PITI, but true homeownership costs run higher. First-time buyers commonly underestimate non-mortgage costs:

The 1% maintenance rule deserves emphasis. On a $350,000 home, that is $3,500 per year — accounting for a new roof every 20–25 years ($15,000–$25,000), HVAC replacement every 15 years ($5,000–$12,000), water heater every 10 years ($800–$2,000), and smaller ongoing repairs. Buyers moving from apartments are often blindsided by these costs because landlords absorbed them previously.

A practical rule: Budget 30%–35% of gross monthly income for total housing costs — not just the 28% that lenders use for qualification — to maintain margin for the inevitable repair bills every homeowner faces.

How Your Existing Debt Reduces Buying Power

Every dollar of existing monthly debt directly reduces the mortgage you can qualify for. This is the most underestimated factor in home affordability calculations. With a $100,000 salary ($8,333 gross monthly):

• No debt: max PITI = $2,333 → estimated home price $355,000

• $300/mo debt (car payment): back-end limit $3,000; minus $300 = $2,700 for housing — front-end cap of $2,333 still applies → home price unchanged

• $700/mo in total debts: $3,000 − $700 = $2,300 max PITI → back-end now the binding constraint → estimated home price falls to ~$350,000

• $1,200/mo in debts: $3,000 − $1,200 = $1,800 max PITI → estimated home price drops to ~$274,000 — an $81,000 reduction

Paying off a $400/month car loan before buying can increase buying power by $60,000 or more. Use our affordability calculator to enter your actual monthly debt obligations and see the precise impact on your home price ceiling.

How Credit Score Affects Your Rate and Buying Power

Your credit score determines the interest rate you receive, which sets your monthly payment and maximum home price. The difference between a 680 and a 760 score on a $300,000 loan is typically 0.5%–0.75% in rate — translating to $95–$140 more per month.

The total cost difference between a 760+ score and a 620 score on a $300,000 loan: $306 more per month and $110,200 more in total interest. If your score is below 700, spending 6–12 months improving it before applying will have a significant and measurable financial payoff.

Fastest credit score improvements before a mortgage application: (1) Pay credit card balances below 30% utilization — the single highest-impact action; (2) Do not close old accounts; (3) Dispute any errors at AnnualCreditReport.com; (4) Do not open new credit accounts within 6 months of applying.

Affordability vs. What You Qualify For

Qualifying for a mortgage and genuinely being able to afford the home are not the same thing. Many financial advisors recommend targeting a home at 2.5× to 3× your annual income — rather than the maximum 4× that lenders might approve — to maintain flexibility for emergencies, retirement savings, and lifestyle spending.

The practical test: after the mortgage, taxes, insurance, maintenance, and all other obligations, do you have enough left for retirement contributions, a 3–6 month emergency fund, and the ability to handle a $5,000 surprise repair without financial stress? If not, that price is not affordable for your situation — even if a bank will lend the money.

Frequently Asked Questions About Home Affordability

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

At $70,000 per year ($5,833 gross monthly), the 28% front-end guideline gives a maximum monthly PITI of $1,633. At 7% interest with 20% down and average taxes and insurance, this supports a home price of approximately $248,000–$265,000 with no other monthly debts. Monthly debts of $300–$400 push your qualifying price toward the lower end of this range. Use our affordability calculator with your exact numbers for a precise figure.

Can I afford a house on $50,000 a year?

Yes. The 28% guideline gives a maximum PITI of $1,167 per month, supporting a home price of roughly $150,000–$180,000 at current rates. Options that help: a co-borrower (combined income), state-specific down payment assistance programs, FHA financing with a lower down payment, or targeting Midwest and Southeast markets where median prices remain below $200,000.

How much do I need to earn to afford a $400,000 house?

To afford a $400,000 home at 7% interest with 20% down under the 28% guideline, you need approximately $95,000–$115,000 in annual gross income. The monthly PITI on a $400,000 home (7% rate, average taxes and insurance) runs approximately $2,700. Dividing by 0.28: $2,700 ÷ 0.28 = $9,643/month gross = $115,700/year needed. Buyers with existing monthly debts or above-average property taxes need income at the higher end of this range.

Is the 28/36 rule still realistic today?

In many major metro areas, the 28% rule strictly applied means renting rather than buying at current price levels. Practically, many buyers in high-cost cities stretch to 32%–35% front-end ratios when income is stable and other debts are minimal. FHA loans formally allow higher DTI ratios with compensating factors. What matters most is that your budget remains sustainable — meaning you retain emergency funds, retirement contributions, and discretionary spending after the mortgage. A ratio that qualifies on paper but leaves no margin for life events is not truly affordable.

Does gross or net income determine mortgage qualification?

Mortgage qualification uses gross income — before taxes, health insurance premiums, and retirement deductions. Your take-home pay may be only 65%–75% of gross depending on tax bracket and benefit elections. Always use your annual gross salary — not your net take-home amount — when running affordability estimates.

What is the maximum DTI ratio most lenders will accept?

For conventional loans (Fannie Mae/Freddie Mac), the standard maximum back-end DTI is 43%–45%, with some automated approvals up to 50% for strong borrowers. FHA allows up to 57% back-end DTI with compensating factors. VA loans have no official DTI cap but most lenders apply a 41% guideline. Jumbo loans are the most restrictive, typically capping back-end DTI at 43% and requiring larger cash reserves. A lower DTI always improves your rate and approval odds regardless of loan program.
