Odds are I'm simply going to get my earnest money back and move on.I'm not a fan of borrowing money to invest, but if you really want to do it then what you could do is this: get a line of credit (LOC) or hard money loan, close on the house and fix it up using that cash, then once you're done with the work get permanent financing to pay off your LOC. 

I'm a big fan of Zillow, but their API data is not what you see on their site and it's only useful for example data, and should not be relied on for any serious value analysis. 

I am personally not a fan of HELOCs, but I may be in the minority.

I'm not a fan of FHA; there are less expensive options. 

(I'm way out of my tax league here!)

I am not sure you are a fan of smaller sub markets (just a hunch from other posts). 

I'm not a big fan of these There is so many questions I want to ask but ill keep it simple and just start with what I mentioned above .

The market I'm in is dry ( Wilmington , NC ) and I'm not a big fan of residential single family or condos  .

I'm actually a big fan of Akron, however, I don't think that Green makes for the best area to get the highest likelihood of getting the greatest amount of return on your investment.
