FHA v Conventional with excellent credit & no debt

[Andrew Del Rio]

Newbie here, looking to get into my first deal. I want it to be a 2-4 unit, used as a primary residence. My question is how should i finance this? I have no debt and a 780 credit score. My understanding is that conventional is cheaper, but for multiple units you have to put down 15%-25% ; and for FHA you only need to put down around 3.5% with a higher PMI. Any thoughts, comments, concerns, suggestions, opinions are much appreciated.
