📚 Learn About Home Affordability

📊 The 28/36 Rule

Lenders use the 28/36 rule: housing costs shouldn't exceed 28% of gross monthly income, and total debt shouldn't exceed 36%. This ensures you can afford your mortgage payment.

Example: $6,000/month income = max $1,680 housing (28%), max $2,160 total debt (36%).

💰 Down Payment Impact

  • 20% Down: No PMI, better rates, lower payment
  • 10-19% Down: PMI required, slightly higher rates
  • 3-9% Down: Higher PMI, higher rates, larger payment
  • FHA (3.5%): Lower credit requirements, MIP required

🏠 Hidden Homeownership Costs

Beyond mortgage payment (PITI), budget for maintenance (1-2% of home value annually), HOA fees, utilities, and repairs.

Example: $300k home = $3k-6k/year maintenance, plus $200-500/month utilities and HOA.

📈 Debt-to-Income Ratio (DTI)

Front-End DTI (28%):

Housing costs only (mortgage, taxes, insurance, HOA)

Back-End DTI (36%):

All debts (housing + car + student loans + credit cards)

✅ Improve Your Affordability

  • Pay down existing debts to lower DTI
  • Increase credit score for better rates (700+ ideal)
  • Save larger down payment (20% = no PMI)
  • Consider lower-cost areas or smaller homes
  • Get pre-approved to know exact budget

⚠️ Common Mistakes

  • Maxing out budget (leaves no emergency cushion)
  • Forgetting closing costs (2-5% of purchase price)
  • Ignoring maintenance and repair costs
  • Not accounting for property tax increases
  • Buying before paying down high-interest debt

Frequently Asked Questions

How much house can I afford with my salary?

A general rule is that you can afford a home 2.5 to 3 times your annual gross income. For example, with a $80,000 salary, you could afford a $200,000-$240,000 home. However, this depends on your down payment, debts, interest rates, and the 28/36 rule. Use our calculator to get a personalized estimate based on your specific financial situation.

What is the 28/36 rule for home buying?

The 28/36 rule is a guideline lenders use to determine how much you can borrow. The "28" means your housing costs (mortgage, taxes, insurance, HOA) shouldn't exceed 28% of your gross monthly income. The "36" means your total debt payments (housing + car + student loans + credit cards) shouldn't exceed 36% of gross income. This ensures you can comfortably afford your mortgage.

How much should I put down on a house?

Ideally, put down 20% to avoid PMI (private mortgage insurance) and get better interest rates. However, many buyers put down less: FHA loans require only 3.5%, conventional loans can be as low as 3%. A larger down payment means lower monthly payments and less interest paid over time. Balance your down payment with keeping an emergency fund (3-6 months expenses).

What other costs should I budget for when buying a home?

Beyond the mortgage payment, budget for: closing costs (2-5% of purchase price), property taxes (1-2% annually), homeowners insurance ($1,000-3,000/year), HOA fees (if applicable), maintenance and repairs (1-2% of home value annually), utilities ($200-500/month), and an emergency fund for unexpected repairs. Don't forget moving costs and initial furnishings.
