What is best sequence for Purchasing Apartments?

[Ernie Sturzinger]

Looking at 11-unit apartment building and want to get info about rent roll, leases, vacancies, etc. Seller agent is vauge and not giving us this info when we asked directly for it. We have not made an offer yet as we need this information to make an informed decision whether to make an offer or not. However, is there a specific sequence of events we should be working through for this to be easier? I wanted to find out this information before making an offer, but wondering if need to make offer first and then go through all of this information gathering after offer accepted? Any insights here? Not sure if I am expecting too much here from seller agent or not? Seems like basic information gathering on my part here, so confused. Thanks!
