Let's say that you are a family with $42,000 Annual Gross Income and monthly revolving debts of $800 for car payment and credit cards, and you have $10,000 for your down payment and closing costs on a 7%-interest mortgage. Without PMI the maximum price you can afford is $44,600, but with PMI covering the lender's risk you now can buy a $62,300 house. PMI has afforded you 39% more house.
