Training on commercial real estate

[Paolo Ruggieri]

I have been successful with residential (built and stabilized 30+ properties portfolio)... I am looking not to pass to commercial.. as I start looking at properties I realize that I see some training on how to value a property... I clearly understand the basics (property value = rent / cap rate) but I need more in depth training as I see how each property is actually quite different (location, property type, % vacancy, type of tenant , offer/demand of that type of property etc)... i am looking for a formal training (book , video etc) or to develop a relationship with a local commercial realtor that can teach me in exchange of future potential business. Any one any advice?
