How Much House Can I Afford? A Realistic Guide for 2026
The biggest mistake first-time home buyers make is looking at listings before understanding what they can actually afford. Not what a lender will approve you for — what you can comfortably pay each month without stretching your finances thin.
This guide walks through how to calculate your real affordability, what lenders actually look at, and why online estimates often overshoot.
The 28/36 Rule: Your Starting Point
Most lenders follow the 28/36 rule when evaluating mortgage applications:
- 28% front-end ratio: Your total housing costs (mortgage payment, property taxes, homeowners insurance, HOA fees, and PMI) should not exceed 28% of your gross monthly income.
- 36% back-end ratio: Your total monthly debt payments (housing costs plus car loans, student loans, credit card minimums, and other debts) should not exceed 36% of your gross monthly income.
Some loan programs are more flexible — FHA loans allow up to 43% back-end in many cases, and some conventional lenders will go to 45% with strong compensating factors. But just because you can get approved at 45% doesn't mean you should.
What Lenders Actually Look At
When you apply for a mortgage, lenders evaluate four main factors:
- Income: Your gross (pre-tax) household income, verified through pay stubs, W-2s, and tax returns
- Debts: All recurring monthly obligations that show on your credit report
- Credit score: Determines your interest rate tier and which loan programs you qualify for
- Down payment: Affects your loan amount, whether you pay PMI, and your monthly payment
Your debt-to-income ratio (DTI) is the single most important calculation. It determines the maximum monthly payment a lender will approve.
Real Salary Examples
Here's what different income levels can realistically afford, assuming the 28% front-end rule, a 30-year fixed mortgage at 6.75%, property taxes at 1.1%, and homeowners insurance at $1,200/year:
$50,000/year salary ($4,167/mo gross)
- Max housing payment: $1,167/mo
- Estimated home price: $175,000 - $200,000
- Down payment needed: $7,000 - $10,000 (3.5-5%)
$75,000/year salary ($6,250/mo gross)
- Max housing payment: $1,750/mo
- Estimated home price: $275,000 - $310,000
- Down payment needed: $9,600 - $15,500 (3.5-5%)
$100,000/year salary ($8,333/mo gross)
- Max housing payment: $2,333/mo
- Estimated home price: $380,000 - $420,000
- Down payment needed: $13,300 - $21,000 (3.5-5%)
$150,000/year salary ($12,500/mo gross)
- Max housing payment: $3,500/mo
- Estimated home price: $575,000 - $640,000
- Down payment needed: $20,125 - $32,000 (3.5-5%)
These ranges assume minimal existing debt. If you have a $500/month car payment or $300/month in student loans, your affordable home price drops significantly.
Why Online Calculators Often Overestimate
Many calculator tools show you the maximum a lender might approve, not what's comfortable. They often:
- Use the 36% or even 43% back-end ratio instead of the more conservative 28% front-end
- Underestimate property taxes (which vary wildly by state and county)
- Ignore PMI costs for down payments under 20%
- Don't factor in HOA fees, maintenance reserves, or utility increases
- Use today's teaser rates instead of realistic locked rates
The result: you see a number that's 15-30% higher than what you should actually target.
The Hidden Costs That Reduce Your Budget
Your mortgage payment is just the start. Budget for these before deciding on a price:
- Property taxes: 0.5% to 2.5% of home value per year, depending on your state
- Homeowners insurance: $1,000 to $3,000+ per year
- PMI: 0.3% to 1.5% of the loan amount per year if your down payment is under 20%
- HOA fees: $200 to $500+ per month in many communities
- Maintenance: Budget 1% of the home's value per year for repairs and upkeep
- Utilities: Often higher than renting, especially for larger homes
How to Find Your Real Number
- Start with your gross monthly income
- Multiply by 0.28 — that's your maximum housing payment
- Subtract estimated property taxes (check your target area's rates)
- Subtract estimated homeowners insurance ($100-$250/month)
- Subtract PMI if your down payment is under 20% (estimate 0.5-1% of loan annually)
- What's left is your maximum mortgage principal and interest payment
- Use a calculator to convert that payment into a home price at current rates

The Bottom Line
The best approach: figure out what monthly payment fits comfortably in your budget first, then work backward to a home price. Don't start by falling in love with a house and trying to make the numbers work.
A good rule of thumb: if your housing costs would take more than 25-28% of your gross income, you'll likely feel the squeeze — especially when maintenance costs, higher utilities, and unexpected repairs show up.
