1. Find a listing for a house you want to buy in an area you wish to live. List the price of the home. 2. Select a bank and state the finance rate for a 30-yr fixed mortgage. 3. Assume you have 20% for the down payment, then what is your down payment and how much will you finance? 4. Go to bankrate.com and search amortization-calculator, based on the amount you need to finance, 30 years, and the finance rate, create an amortization table. What is your monthly mortgage payment? Also, determine the total amount of interest you will pay over 30 years from the amortization table. 5. Now, assume you will pay $100 extra each month toward your mortgage. How many years will you shave off of your 30-year loan? How much interest will you save?
