常見問題
What is PITI?
Principal, Interest, Taxes, and Insurance — your full monthly housing payment.
How much down payment do I need?
20% avoids PMI on conventional loans; many programs allow 3–5% down.
Should I get a 15 or 30 year loan?
15-year saves interest dramatically; 30-year gives lower monthly payments and flexibility.
