Multi Family Units in Milwaukee

[Jeff Wells]

Looking to invest in the Milwaukee market, the returns look great on my screen.  I'm currently in Washington state so the pucker factor of going outside my state is a bit higher.  I've poked through the forums and really haven't seen an answer to this.  Why does it seem like the commercial +5 units cash flow twice if not three times harder in Milwaukee than a 1-4 unit?  

For example, there are quite a few deals in Milwaukee of 12 unit brick apartments for ~325K which cash flow (9-11K a month) and 3-4 unit for the same cost seem to bring in (3-5K a month).  Seems almost too good to be true, could it be maintenance, management, utilities, or taxes...).  Appreciate your candid feedback in advance.
