I would like to know the Florida state law behind the landlord of my property selling the property to a new owner without notifying the tenants till after the transaction has taken place, now the place has been sold the new landlord gives us the option to either sign a new lease and pay 225 more dollars a month or move before the next months rent is due, if I choose not to sign the new lease how much time by law am I suppose to be given, and if the next month come and I have not found a new place can they just come and change the locks and kick me out, or would they have to evict me.

Yes they can tell you to sign the lease or move. They have to go through the formal eviction of giving you a written notice to leave.

I think the three day is if you haven't paid your rent and may be more days for other reasons.

Florida Evictions

Do you currently have a written lease in effect? If you do then the new owner has to honor it. They can't increase the rent or change any other terms until your old lease has expired.

If you don't have a written lease in effect at the moment then the new owner can require that you sign a new lease and can increase the rent with 30 days notice.

I was a landlord in Florida and LisaB has given the correct answer to this question. The new landlord must honor the signed lease with the old owner until it expires.
