4. One real estate sales technique is to encourage customers or clients to buy today because the value of the property will probably increase during the next few years. "Buy this lot today for $30,000. In two years, I project it will sell for $32,500." Let's see if this is a wise investment.
In two years the future value is projected to be $32,500. If the interest rate is 12%, compounded annually, what amount should you invest today to have the $32,500 in two years.
Using Table 10-3 in your textbook, the factor for 12% and two periods is 0.79719.
Present value = $32,500 X 0.79719 = $25,908.68.
By investing only $25,908.68 today at 12% for two years, you will have the $32,500 needed to purchase the land. You have actually paid only $25,908.68 for the lot, a savings of $4,091.32 on the $30,000 price. Of course, there can be problems with waiting to buy.

Thus, the simple interest paid is $15,280 * 0.165 * 12 = .
For compound interest, compounded annually, the total amount owed after n years is:
P(1+r)^n where P = principal, r = annual interest rate, n = number of years.
