Home Affordability Calculator: How Much House Can You Really Afford?

Introduction

Buying a home is one of the most significant financial decisions you'll make. Our Home Affordability Calculator helps you determine a comfortable price range based on your unique financial situation, ensuring you don't overextend yourself.

The 28/36 Rule Explained

Most lenders use the 28/36 rule as a benchmark for mortgage approval:

• Housing Ratio (28% rule): Your total housing costs (mortgage, taxes, insurance, HOA) should not exceed 28% of your gross monthly income.
• Debt-to-Income Ratio (36% rule): Your total monthly debt payments (including housing) should not exceed 36% of your gross monthly income.

Example Calculation:

• Annual Income: $100,000 ($8,333/month)
• Maximum Monthly Housing Payment: $2,333 (28% of gross income)
• Maximum Total Monthly Debt: $3,000 (36% of gross income)

Key Factors Affecting Home Affordability

1. Down Payment Impact

• 20% or more: Avoids PMI, better interest rates
• 10-15%: Requires PMI but lower upfront costs
• 3.5-5%: FHA and conventional low-down options
• 0%: VA and USDA loans (for qualified buyers)

2. Credit Score Influence

• 760+: Best mortgage rates, most loan options
• 700-759: Good rates, wide range of loan options
• 650-699: Higher rates, fewer loan options
• Below 650: Limited options, higher down payments

3. Debt-to-Income Ratio (DTI)

• Ideal DTI: 36% or lower
• Maximum DTI: 43% (varies by lender and loan type)
• How to calculate: (Monthly Debt Payments + New Mortgage Payment) / Gross Monthly Income

Hidden Costs of Homeownership

1. Property Taxes: Typically 1-2% of home value annually
2. Homeowners Insurance: $1,200-$2,500/year (varies by location and coverage)
3. Maintenance: Budget 1-4% of home value annually
4. HOA Fees: $200-$800/month (if applicable)
5. Utilities: $200-$500/month (varies by home size and location)
6. Closing Costs: 2-5% of home price
