🔹 The 28/36 Rule
Lenders use this guideline: housing expenses (PITI + HOA) should not exceed 28% of gross monthly income, and total debts (housing + other) should not exceed 36%. Our calculator follows this conservative rule.
🔹 What's Included in PITI
Principal, Interest, Taxes, and Insurance. Plus HOA fees if applicable. Our calculator accounts for all of these to give you a realistic monthly payment.
🔹 Down Payment Impact
Larger down payment means lower loan amount, smaller monthly payment, and may eliminate PMI. 20% down is ideal, but many loans allow 3-10% down.
🔹 Debt-to-Income (DTI) Explained
Front-end DTI = housing expenses / income. Back-end DTI = (housing + other debts) / income. Lower DTI improves approval odds and interest rates.
🔹 Interest Rates Matter
A 1% difference in rate can change affordability by tens of thousands. Use our calculator to compare rates and terms.
🔹 Hidden Costs of Homeownership
Beyond mortgage: maintenance (1-2% of home value/year), utilities, HOA increases, and special assessments. Budget extra for surprises.
