Do I have to pay rent if my landlord is trying to sell my duplex?

He is in jeopardy of losing the place and it is in bad condition. It could become a short sale as he is frivolous with his money. He has been trying to sell it for over a year and might lose it to the bank.I have been here 7 years and maintain this place despite the neighbors that have been out of control for the last 3 years.What are my rights and options as I cannot afford to move right now. Do I have a window of time to where I don't have to pay my rent?
