And in many cases getting an accurate forecast is very difficult or even impossible to do.The good news is that you are actually thinking about this. 

Seller financing is an option I have considered but in my market that’s almost impossible.

From what I hear from active participants (and read) for those doing deals in the DFW metro region, it is hard, but not impossible.

Does my mortgage become impossible to pay off?
