If you want to buy a home with 10% down there are ways.
1st you will probably enjoy your new home if you have at least $25,000-$30,00 in a cash emergency fund at minimum. My opinion is that you should save another $20,000 and go for it at the end of the year. And who knows maybe that $400,000 home is $350,000 by the end of the year?
If your loan is under $417,000 you can have the PMI paid upfront in closing by the seller and never have to pay it. Even with PMI your payment is around $2300. Very similar to rent or cheaper depending on your location. Look at Aimloan.com or Amerisave.com
