Thanks guys, yes that what my understanding too can't get loan for flipping houses from the bank.I found some private money lenders but still kind of scary.I got to the point where I have to start and I am ready for the new challenge and the risk

A Challenge at that time of year is winter is fast approaching and filling rentals in winter is harder to do.  

I would echo @Luka Milicevic in that your greatest challenge will likely be finding a deal that makes sense.

Additional books that focus on what you choose could be a good next step.

I really want this house but I can not seem to get the seller to take any action what should my next step be?

Finding the sources of the data, clean it and then getting it to flow is the challenge.
