How Much House Can I Afford?

On February 25, 2026  By newsroom   Topic: Buying A House

Determining how much house you can afford involves more than just calculating your monthly mortgage payment. Here's a breakdown to guide your decision:


Key Insights

  • Mortgage Payment: Should not exceed 28% of your gross monthly income.
  • Debt-to-Income Ratio: Lenders prefer a DTI ratio of 36% or lower for loan approval.
  • Additional Expenses: Factor in property taxes, insurance, maintenance, and HOA fees.

Rules to Estimate Affordability

  • One-Third Principle: Your mortgage should be no more than three times your annual income.
  • Example: $100,000 annual income = $300,000 maximum mortgage.

  • 28/36 Rule:

  • Mortgage payment \u2264 28% of gross monthly income.
  • Total debt payments (mortgage, car loans, credit cards, etc.) \u2264 36% of gross monthly income.

Example: If you earn $7,000/month:
- Max mortgage = $1,960 (28%).
- Total debt = $2,520 (36%).


Factors Affecting Your Mortgage Limit

  • Credit Score:
  • A FICO score of 580 - 620+ is typically required for mortgages.
  • Higher scores = better interest rates.

  • Income and DTI:

  • The lower your current debt, the more you can allocate to your mortgage.

  • Down Payment:

  • 20% down avoids private mortgage insurance (PMI).
  • Higher down payments lead to lower monthly payments.

  • Interest Rates and Points:

  • Lower interest rates reduce monthly payments.
  • Consider paying discount points for a better rate.

  • Additional Costs:

  • Closing costs: 2-5% of home price.
  • Insurance: Average annual cost is $1,249.

4. Desired loan term (15 - 30 years).
5. Property taxes and insurance costs in your area.


Tips for First-Time Buyers

  • Don't stretch your budget to match a lender's approval. Aim for comfort, not just maximum borrowing.
  • Plan for unexpected costs like repairs and emergencies.
  • Compare offers from multiple lenders to find the best rate and terms.
