Depending on your situation, PMI may be worth it. For example I was paying 1200 a month for a 1 br apartment. They wanted to up it to 1500 a month. Instead I bought a house with 5% down. The total monthly payment for a 200k house, including PMI, is 1,100 a month.

Even with PMI I am still paying less than living in the same apartment year over year.
