Commercial office/retail space deal analysis resources

[Dustin Le]

Hi, for context, I have a converted duplex, but no commercial real estate experience. My goal is to start with a 3-5 unit commercial building for office/retail space. If you have experience in this space, do you have any resources or advice for what to consider when looking at when underwriting a potential property? I'm looking for a resource that is structured to help me go from knowing nothing to knowing enough to make an offer and feel confident in my decision. 

Thank you in advance!
