Question about "due dilligence" on apartment building purchase

[Brian Fournier]

Hi Everyone,

I am in the process of making an offer on a 12-unit apartment building.  I have owned smaller rentals but this is my first "commercial" sized acquisition.  My question is about the "due diligence" period between the acceptance of offer and the closing.  Other than inspecting the physical condition of the property itself, what other things should I be looking into?  Also, how much information about the current tenants should I expect to get from the seller at this point in the negotiations?

Thanks!
