4. In 2006 Juan and Maria purchased a home for $250,000. They were offered a 30-year loan by a mortgage broker for no money down, interest only for the first three years at 3%, then automatically converting to an amortizing loan at 2 points above the prime rate (the prime rate is now 5%). What was their initial monthly payment, and what did it become after the reset?

5. What does the loan adjustment in problem 4 tell you about the financial crisis in the housing market in 2009?
