How much house you can afford depends on three things: your income, your debts, and your down payment. Lenders use the 28/36 rule — spend no more than 28% of gross income on housing, no more than 36% on all debts. This guide gives you the exact numbers for every income level, home price, and down payment scenario.

The 28/36 Rule: How Lenders Decide What You Can Afford

Banks don’t just look at your salary. They evaluate two ratios:

Ratio What It Measures Maximum
Front-end (28%) Housing costs ÷ gross monthly income 28%
Back-end (36%) All debt payments ÷ gross monthly income 36%

Housing costs include your mortgage payment (principal + interest), property taxes, homeowner’s insurance, and PMI if applicable. All debt payments add car payments, student loans, credit card minimums, and other monthly obligations.

Example: You earn $80,000/year ($6,667/month). The 28% rule means your maximum housing payment is $1,867. If you also have a $400/month car payment and $300/month in student loans, your total debts should stay under $2,400 (36% of $6,667).

Some lenders allow up to 43% or even 50% back-end ratios for qualified borrowers, especially with FHA loans. But just because a bank will lend you more doesn’t mean you should borrow it. The 28% rule exists because going higher leaves you financially fragile. A clear household budget helps you determine what you can comfortably afford.

How Much House Can I Afford by Income

Here’s the maximum affordable home price at each income level, assuming 10% down, 6.5% interest rate, and the 28% housing ratio:

How Down Payment Changes Your Affordability

The same income supports very different home prices depending on what you put down:

Down Payment Home Price on $100K Income Loan Amount PMI? Monthly Savings vs 3% Down
3% ~$340,000 $329,800 Yes (~$165/mo)
5% ~$355,000 $337,250 Yes (~$140/mo) $25/mo
10% ~$375,000 $337,500 Yes (~$110/mo) $55/mo
15% ~$400,000 $340,000 Yes (~$85/mo) $80/mo
20% ~$420,000 $336,000 No ~$165/mo

PMI (Private Mortgage Insurance) is required when you put less than 20% down. It typically costs 0.5%–1% of the loan amount annually and falls off once you reach 20% equity. Despite the extra cost, buying with less than 20% down can make sense when:

  • Home prices are rising faster than you can save
  • You have a strong emergency fund and stable income
  • Renting costs more than owning with PMI included

See our Average Down Payment Guide and Down Payment Assistance Programs for help with the upfront cost. Also see Average Closing Costs — these typically add 2-5% on top of your down payment.

Costs Most Buyers Forget

The mortgage payment is just the start. These additional costs can add 30-50% to your monthly housing expense:

Hidden Cost Typical Amount Annual Total
Property taxes 0.5%–2.5% of home value $2,000–$10,000
Homeowner’s insurance $1,500–$3,500/year $1,500–$3,500
PMI (if <20% down) 0.5%–1% of loan amount $1,500–$4,000
HOA fees $200–$500/month (if applicable) $2,400–$6,000
Maintenance & repairs 1%–2% of home value $4,000–$10,000
Utilities $200–$400/month $2,400–$4,800

On a $400,000 home, these extras can add $1,000–$2,500 per month on top of your mortgage. Factor these in when calculating what you can actually afford.

Affordability by State

The same salary buys very different homes depending on where you live. Median home prices and the salary needed to afford them in popular states:

Texas ~$300,000 ~$81,000 Salary to buy in Texas
Florida ~$380,000 ~$103,000 Salary to buy in Florida
Georgia ~$320,000 ~$87,000 Salary to buy in Georgia
North Carolina ~$330,000 ~$89,000 Salary to buy in North Carolina
Arizona ~$390,000 ~$106,000 Salary to buy in Arizona
Virginia ~$400,000 ~$108,000 Salary to buy in Virginia

Buying With a Partner: Combined Income

Dual-income households can afford significantly more. Here’s how combined incomes change the picture:

Combined Income Max Home Price (28% rule) Detailed Guide
$100,000 ~$370,000 Full breakdown
$150,000 ~$570,000 Full breakdown
$200,000 ~$760,000 Full breakdown
$250,000 ~$955,000 Full breakdown

Important: Lenders look at both incomes for qualification, but also both debts. If one partner has high student loans or car payments, it can offset the benefit of the second income.

When Renting Makes More Sense

Buying isn’t always the right financial move. Consider renting if:

  • You’ll move within 3-5 years — transaction costs (closing costs, realtor fees) mean you need time to break even
  • Home price-to-rent ratio exceeds 20 — if a $400,000 home rents for $1,500/month, the ratio is 22, favoring renting
  • You have high-interest debt — paying off 20% credit card debt delivers a guaranteed return that likely beats home appreciation
  • You haven’t built an emergency fund — homeownership has expensive surprises

See Rent vs Buy Calculator and Renting vs Buying a House for a detailed comparison.

The Bottom Line

The 28% rule is your starting point: multiply your gross monthly income by 0.28 for your maximum housing payment. But the real answer depends on your down payment, existing debts, local property taxes, and what you’re comfortable spending. Use the income-specific guides above for a personalized breakdown, and remember — just because a bank approves you for a certain amount doesn’t mean you should borrow that much. The best mortgage is one that still lets you save 15-20% of your income for retirement.

Affordability Decision Framework

If you are payment-constrained

If you are cash-constrained

  • Prioritize closing reserves and emergency fund.
  • Test lower down payment with PMI versus waiting to save more.
  • Review PMI Guide and Average Down Payment.

If rates are your main concern

  • Run affordability at current rate and +1% scenario.
  • Evaluate if the home still works without assuming a future refinance.
  • Use Mortgage Rate History for context, not prediction.

Stress-Testing Payment Durability

Scenario Assumption Use
Base case Current quoted rate + expected tax/insurance Initial home-price band
Rate stress +1.0% rate Determines risk tolerance
Cost stress +15% insurance/tax/utility burden Tests post-close durability
Income stress 10–15% temporary income drop Validates emergency runway

A home is meaningfully affordable when all four scenarios are survivable without high-interest debt.

Buyer Readiness Framework

Rate each of these as strong, moderate, or weak before locking a target budget:

  1. Income stability: Is household income predictable over 12 to 24 months?
  2. Cash reserves: Will you keep emergency and maintenance buffers after closing?
  3. Debt position: Do current obligations limit flexibility if one income changes?
  4. Time horizon: Are you likely to stay long enough to absorb transaction costs?
  5. Repair tolerance: Can you absorb expected and unexpected ownership costs?

If two or more areas are weak, reduce budget range or delay until the risk profile improves.

Common Affordability Mistakes

  • Shopping by lender pre-approval maximum instead of personal comfort range.
  • Using teaser assumptions for tax, insurance, and maintenance.
  • Exhausting cash reserves for the down payment.
  • Ignoring commute and utility cost changes.
  • Assuming refinancing will always be available quickly.

12-Month Post-Purchase Stabilization Plan

  1. Keep non-essential upgrades limited in the first six months.
  2. Rebuild any emergency-fund drawdown immediately.
  3. Track full housing cost monthly, not just principal and interest.
  4. Reprice insurance and recurring contracts after closing.
  5. Re-evaluate principal prepayment only after buffers are restored.
