๐ How Does Home Affordability Work?
Lenders use the 28/36 rule: housing costs (P&I, taxes, insurance, PMI, HOA) should not exceed 28% of gross income. Total debt (housing + car, student loans, credit cards) should not exceed 36%. This calculator reverse-engineers your max affordable home from these limits.
๐ฏ Expert Tips
Get Pre-Approved First
Pre-approval shows sellers you're serious and gives you exact budget. Rates locked 60-90 days.
Keep DTI Under 36%
While lenders may approve up to 43% DTI, staying under 36% provides buffer for unexpected expenses.
Save 20% to Avoid PMI
20% down eliminates PMI, saving $100-300/month. Consider waiting if you're close.
Factor in All Costs
Include property taxes, insurance, HOA, maintenance (1% annually), and closing costs (2-5%).
