House hacking in Louisville

[Matthew Tuley]

Hello, so I rent now plan on buying a house in a year or so with my girlfriend. But I want to potentially house hack a duplex for the year. I was thinking I would do a FHA loan 3.5% down for the duplex. How long would I have to live in that duplex as my primary residence? And when I go to but my next primary residence would I be able to do a 3.5% down loan again? i have never owned a loan and have credit score around 775 and make about 60,000 a year with my W2. Anybody with experience or knowledge in this scenario?? Thanks in advance!
