Ummm what the F?

My landlord texted me the following

Hey guys, I hope you are doing well. The owners have given me numbers for rent renewals this year. Your current rent is $2445. Your renewal rent will be $2455. Your decision is not due until 4/21/2025. If you come do a decision anytime before then feel free to let me know. Thank you!

And then I received this. Hey guys, I have just received word from the owner that they will be listing the house for sale. With that, the renewal offer from earlier this year is rescinded.

Is this legal?? I can’t just move somewhere else I have no where to go.
