Refinancing a primary residence FHA loan on investment property

[Nicole Barry]

I have a 9-year old primary residence FHA loan on a property that used was my primary residence, I do not pay PMI. Now it is an investment property. I'd like to refi to take advantage of lower rates. My mortgage co says that I can do a streamline refi, but I'm assuming that they mean for a primary residence, which the home isn't. Can I request to streamline refi my current FHA primary home loan into an investment loan? Would it still benefit me financially to do so?
