How to much to pay per unit for a small multi family property

[Anna Sam]

Hi

I wanted to find out how much per unit is everyone paying based on monthly rent.
I have a 12 unit property that I am negotiating with.

rents are 500 (1 bed/1 bth) and 600 (2 bed/1 bath). seller is asking close to 45k per unit which is little bit on the higher side I think.

Thanks
