That really stinks that it happened like that. But at least she was ablt to get it taken care of and now she is making her money back on it. To get a house at that price there is no doubt that it probably needed quite a few things beyond the roof!
It just goes to show what a little elbow grease and of course patience can do.
What is she getting as far as rent goes? Is it enough to cover house payments, insurance and some on the repairs each month?
