Hmmmm, I'm not an expert so please understand I'm just expressing an opinion or maybe trying to help by asking more questions. Personally, I like 3-4 plex as income producing properties. A few things I asked reading your post is how old is the property?, does it have tenants in it?, are you including as income rent you are charging yourself?, and how much cash or OPM do you have for repairs/improvements after you buy it?, what is the ARV? What are the area comps both rental and sales?
If you live in one of your units you have cut what you expect as income. If you plan to do that it is okay but remember to run your numbers with that scenario.
Brandon has said many times the first property you buy won't make you financially rich... it's the education and confidence that will lead you to the next deal and the next deal and the next deal... that will. Because of that I would encourage you to run the numbers as accurately as possible, be honest with your goals, and if the property seems to align with your goals...GO FOR IT!
