I'm not sure about the legal rights in your area but I don't think he can just kick you out like that.

If there is no law to protect you then I would make sure the house looks a wreck when potential buyers come and look at it. I would tell them the plumbing is always backed up and the hot water heater is ready to go out and that the gas pipe has a leak and on and on and on. Anything you can think of that is wrong with the house tell the potential buyers about it. If you had a problem with rodents, bad neighbors just keep thinking of all the negative things wrong with it to keep anyone from wanting to buy it.

Run them off anyway you can because he deserves it since he lied to you.

Good luck!
