Who is giving you this info? You do not need to go FHA if you have 10% down. That is a total waste of you money because you are going to pay PMI and an upfront PMI fee.
You can go conventional with 10% down as long as you are under the $417,000 which you are!!!
PMI will be about $200 extra month. Your closing costs will be about $4,000 for a conventional and about $12,000 if you go FHA.
