Question: Enrico has planned to have $40,000 at the end of 10 years to place a down payment on a condo. Property taxes and insurance can be as much as 30% of the monthly principal and interest payment (i.e., for a principal and interest payment of $1,000, taxes and insurance would be an additional $300). What is the maximum purchase price he can afford if he'd like to keep his housing costs at $950 per month?
