My parents have been renting rooms in their second home since they've been unable to sell the house for the last 5 years. They've finally decided to do a short sale and have accepted one of the offers and sent it to the bank. Since it's the second offer that the bank has received after the first one was retracted by the first potential buyer, their real estate agent has informed them that the 2nd offer is usually processed and finalized in about 30 days.
The problem is that my parents have one tenant left in the house and she's a nightmare hoarder who is refusing to move out even though we've told her repeatedly that the house is sold. The eviction process would take too long and she's current on the rent so what grounds would we have anyway. What happens to her? What rights do the new buyers have because they don't have a lease agreement with her? Does she become a trespasser and get kicked out by the sheriff? I really don't know.
