The Taylors have purchased a $300,000 house. They made an initial down payment of $10,000 and secured a mortgage with interest charged at the rate of 7%/year on the unpaid balance. Interest computations are made at the end of each month. If the loan is to be amortized over 30 years, what monthly payment will the Taylors be required to make?

What is their equity (disregarding appreciation) after 5 years? After 10 years? After 20 years?
