FHA small multi-family underwriting strategies

[Manuel Fontan]

Hello BP community,

I'm a newbie real estate investor, looking to buy my first investment property next Summer 2020 outside of Boston. I was wondering about underwriting guidelines for small multi-family properties. 

What strategies can be explored if I want to purchase a 2nd property with a 730 credit score and living on the first one for 14-16months? I have read mixed reactions on the forums, some people mention that a 20% equity is required, others that 2 years living on the property is required, even read that a letter explaining the reason for moving might be enough to satisfy underwriting and execute a 2nd deal.

Any help sorting this out is greatly appreciated!

Best.
