BRRRR Method and FHA/230k

[Nicole B.]

I'm currently renting, new to real estate, and about to be a first-time home buyer. I've been reading about the BRRRR method. I want to start my real estate adventures with a multi-family we can live in and rent. I've been preapproved for $155k FHA. I'm wondering if I go with a fixer-upper and 203k loan, if and how I could potentially refinance at some point? Is that even possible with a 203k, given the rehab costs are included in the loan?

Also, should I purchase under my business or personally?

Thanks for your help!
