FHA loan advice

[Leah Ramsey]

Hello! 
I'm considering looking into the FHA 3.5% down loan to get a start in Realestate.
my questions:

I get the loan live there for a year then rent it then do it again, but do I have to switch lenders to do it again each year until I have reached my maximum FHA (which I belive is 4 FHA loans)

If I have to switch lenders what is this process like?

Thanks to all!
