What this scenario tells you
A $750,000 home with $150,000 down (20% LTV) financed at 5.5% over 30 years produces a principal-and-interest payment of about $3,407 per month. Over the life of the loan you'd pay around $626,423 in interest. Add property taxes (~1.1% of home value annually), insurance, and PMI if applicable to estimate your full PITI.
