You bought a house for $175,000. You obtain a loan for a mortagge for $120,000 with an annual interest rate of 10% for 20 years. What is the monthly Mortgage Payment? If you sell your house a few years from now at $262,500. Calculate the $ profit on your equity and the HPR% assuming the debt balance has remained the same. Maybe try and use the PMT function on excel which would be =PMT(rate/freq,term*freq,amount)
