What Is the Monthly Mortgage Payment on a $500K House?

The monthly mortgage payment on a $500,000 house with 20% down ($100,000) at 6.5% for 30 years is $2,528 for principal and interest. Add property tax ($417), insurance ($208), and your total monthly housing cost is approximately $3,153. You need a household income of approximately $135,000 to comfortably afford this at the 28% housing cost ratio.

With smaller down payments the numbers increase. At 10% down ($50,000): loan $450,000, P&I $2,844, PMI $270, total $3,739 — requiring roughly $160,000 income. At 5% down ($25,000): loan $475,000, P&I $3,002, PMI $296, total $3,923 — requiring $168,000. At 3% down ($15,000): loan $485,000, P&I $3,065, PMI $303, total $3,993 — requiring $171,000.

Over 30 years at 6.5% with 20% down, you pay $509,975 in total interest on a $400,000 loan — more than the original purchase price. This is why many advisors recommend 15-year mortgages for higher-income buyers: a 15-year at 6% on $400,000 is $3,375 per month but saves $252,400 in interest.
