I would like to know the best time to prune my Mandevilla vine here in Central Florida. As I am not dealing with frosts, or a definite winter season, need a fresh start for a bushier look. Any possibility of damaging by cutting back severely to 4 inches above ground? Please advise.

You can prune them heavily. There will be no issue with this. It is best to do this after the flowers fade, and before new vegetative growth starts.
