Consider a homebuyer/investor who plans to buy a new house, the price of which is $ 500,000. Suppose the buyer does not have any initial savings for the down payment. To buy the house, he needs to borrow $ 500,000 from a bank in the form of a mortgage loan. The mortgage is a 15-year-fixed-rate mortgage. If interest rate is 10 percent, compute the annual payment of the homebuyer.
