I rent a condo in Florida and the owners are now selling. I would like to get out of my lease early.?

Is it possible to terminate my lease early? I am not comfortable with strangers coming into my home while I am away. I feel this is an invasion of privacy. My yearly lease is up on March 1. I offered to move out by Oct 1 and I will also pay the rent until Nov. 1 and they said no. Is it feasible for them to sue me for the four months rent? Is it even worth it for them. Technically, I am giving them two and a half months notice to find another tenant or to sell the condo. I think that is very reasonable. They are looking at selling the unit for over $200,000 and I pay $1000 a month. With that much negative cash flow they have no prayer of selling this thing anytime soon. Any thoughts are appreciated.
