Another potential deal that I am trying to figure out

[Helene Goodworth]

ok guys and gals. 

I learned my lesson from the last one. I was missing a lot of data. This time I decided to make my own spreadsheet instead of using someone else's. It is moderately detailed. The grey areas are the areas in which I can add data. The rest are formulated. I have one box with costs (both listed and what i would offer). The next box has income (both what is listed and what is market value). The next is ROI (I hope I did the right calculations). If any of it doesn't make sense let me know.

I really loved the advice on my last post so am welcoming any advice again this time. It's the best way to learn!
