Is it possible to have a 95% LTV loan if I already have an FHA?

[Lucas Hammer]

So I have an FHA loan on a multi-unit that I'm currently living in, but I want to look at a SFH for myself and move out now that I've been here a couple years. Do I need to refi my FHA to get a 5% down conventional on a single-family? I'm hoping to buy with something other than FHA for my single-family so the PMI will roll off on its own when I hit 80% LTV.
