You may not be able to say but the landlord did say I can go month to month if he doesn't sell the condo by March 1st but that he can't guarantee how long I will be able to stay (I told him I'm moving across country in June)

What I'm worried about is if he sells but the sell falls through because I refuse to move out because my wife and I have no where to go, can the landlord sue us for the sale not going through?
