Is Buying for Equity, but low cash flow a good idea?

[Justin C Huggins]

So I have found a duplex , which is bank owned, which will cash flow very strong with a little rehab. I am definitely going after the duplex. The bank also has 2 houses right next this duplex, which all have same rustic style, built same year.  Both houses need a little rehab work, but mainly cosmetic.  They could easily appraise for quite a bit more, which could give me roughly 30K per house I can put to other rental properties.  Unfortunately, this is somewhat a rural area and I do not believe I could get much more than $600 a month rent.  So after the refi, I would only net around $100 a month on each and this is before maintenance, vacancy rate, etc.  Would it be a good idea to even go after these homes, or would they be more trouble than they are worth after the refinance?   Any suggestions on this, I am fairly new investor.
