How are folks scaling with 2+ FHA loans in a year ?

[Nicole Ferrara]

Hello! 
Ive hear in various podcasts how new investors do an 3 % down and the. Rent it out and do another fha within the same year

I am curious how they do that if there are term live in requirements 

Are there qualifying events (like emergency/ job/relocation) that allow you to rent out the first FHA , in order to get a second fha deal in the same year ?

Do they use the same lender or product typically ? 

Can this be done within the same state and area ? 
thanks
