Purchasing my FIRST MULTI-FAMILY-12 unit apartment-Any Advice?

[Krystyna Fennelly]

I'm super excited to be purchasing my first multi-family property, a 12 unit apartment (8 one bedrooms, 4 two bedrooms) in a great suburban area.  I've been a residential Real Estate Broker 17 years and have been investing in single family homes for hold and flip for 12 years; but commercial is a bit of a different ballgame and I'd love some advice, pretty please.  

Contract executed yesterday, 21 day feasibility period starts today, planning inspections for Tuesday...

-Mistakes to avoid?

-Items to not overlook inspecting?

-Anything specific I should check with the city? 

-Any and all advice is welcome!  I just want to make sure I don't miss/overlook something as I transition into the commercial world.

Thank you!
