The thing about this duplex is the setup. The first floor is 1 BR but I was unable to check it out. However the 2nd apartment is a total of 4BRs I am not kidding. It is setup kinda differently. For any of the multifamily investors have you seen anything like this? Right now owner is asking for 100K. Im interested in wholesaling this but what does the BP fam think of this property. The rent on the first level is $800/Mo.

What would be the cost to make this a triplex?
