Estimated rehab costs $20,000.  

I am trying to avoid hard money as the project is estimated to take up to a year due to weather conditions, area restrictions etc. 

Here's what I found after a little research:Duplex4 bed/1.5 bathComps: $160k - $285k (at least what I can tell from zillow/trulia)Houses on the same street (in much nicer condition) are estimated on homes.com for $236k-$436k.

I wonder if your cash flow estimation is perhaps overly optimistic.

Estimating repair cost comes next, then you can be a wholesaler doing things the right way.....which isn't taught by gurus.
