I just bought a 30' 1978 Hunter in Glades for $6,000. It was full of mud daubers and covered in mildew. Within 5 days or 5 people working we were able to get her in the water and head out to Ft.Myers. There was a continual list of jobs to get her through the sea trials and back, but we got a great deal.
Spend alot of time calling marina's, and getting to know the boat you're going to buy. The Florida climate is not forgiving to paint, wiring, or anything else, so be mindful of the time you're going to have to be on land working in a high priced work yard.
My boat is done except for the deck paint, and back in storage until next winter. Bahamas bound!
