Wholesaling 9 unit building...Help

[Lamontay Garrett]

I have a meeting with a potential seller of a 9 unit building here in San Antonio. It was a bandit sign lead and when discussing the SFR he is wanting to sell, I also found out he owns the 9 unit building as well. He owes very little on the Mortgage and just wants to get rid of it. I don't know how to estimate the value of a commercial property and if anyone locally has any experience with wholesaling small apartments, your assistance would be greatly appreciated. Thanks.
