I was planning to bills my own software based on my books, when I first saw houseflippingspreadsheet I decided that it was close enough to what I was going to build that there was no reason to replicate it.It's not exactly what I would have built (like you said the methodology and format is a little different) but it's definitely just as good, if not better than I would have come up with.

There is no magic way to build a ton of equity in a short time. 

-repairs and cap-ex can be the most challenging aspect for new investors, there are no standard rates that will work across the board. $200/mo is a safe bet for a SF of this size for cap-ex, and your repair estimate looks ok.

(Another option to the above scenario is to instead have the LLC lend my father money to complete the rehab so all the repairs are made in his name...but then the LLC would get no tax deductions on the rehab, plus my father would wind up paying interest on the loan and the LLC would incur taxable income on the interest of the loan as well.)I've said a lot here, but It would be greatly appreciated if anyone can give me advice on the best strategy to pursue...Thanks!

The trouble I am having is there is no comps to look at in the immediate area, so I just took some comps that were miles away up further north, and subtracted a little bit since the area was located near more desirable restaurants and shopping. 

Thats all id recommend for now, no need to get to complicated so soon!
