What if my lease says nothing about notification of non-renewal?

[Patrick Philip]

I manage a trailer park. We are considering selling the land and all the trailers on it. Therefore, we would not renew leases when they expire. Our lease doesn't have any guidelines for this, and the Florida Statutes simply says to refer to the lease. What are the rules here? I don't want to give them too much notice because then they will just stop paying. But I don't want to just tell them 3 days before the fact, either.

I think a good solution would be to tell them right after they pay the final month's rent, but there is one problem with that. Often, the tenants don't pay on time and I collect late fees. Plus, once I tell one of them, the rest will know anyway unless I cleverly disguise it as if I'm just selling individual trailers until they are all gone

Kind of reminds me of the story of Walt Disney buying all that land in Central Florida for Disney World under dummy corporations. Even though it's completely different, it still reminds me of that somehow.
