is there a company in florida that sells and moves mobile homes to an existing vacant lot ?

Stewart Mobile Homes in Tampa

This park in particular does not...but yes there are quite a few...also, may want to check into purchasing insurance for when they move it for you, JUST IN CASE

Not sure if there's a vacant lot but they usually make room for a new one. This park is very large so there some streets I don't even go down, There may be some empty ones.

Yes check on google to find them
