I received a phone call from a sweet old lady who for selfless family reasons left her home behind and moved a whole state away. 

After she changed her mind so many times already, there was no way I was just going to hand her cash but we agreed that with an accepted offer, I would give her cash and record a mortgage against her property for that amount.Now after driving her to and from the title company to have them help explain things and record the mortgage, giving her cash, a trip to her house when swore she wanted to sign but then got cold feet, responding to all her mood swings via long texts and phone calls, she says she changed her mind and doesn't want to sell.
