To arrive at an "affordable" home price, follow the guidelines of most lenders. Allowed a total debt-to-income ratio of no more than 36 percent. And assume a housing payment-to-income ratio of 28% for a conservative estimate, and 33 percent for an aggressive one. Before buying, however, you should also factor in other savings needs, including retirement and college. ASSUMPTIONS: Assumed a 30-year mortgage term, annual property tax of $2000 and homeowners insurance of $500 for the metro Phoenix area.
