I've been in FL for more than 10 years now and I don't think I'm being nickel and dimed on fees over taxes. Yes, there is a new plate fee which is somewhere in the $200 range, if you use the same plate in your next car you don't pay this fee again, even if there is a gap in ownership if you retain the plate. That plus registration puts a new car in the state in the $400 range. Renewals happen every year on your birthday (happy borthday!) but are significantly less expensive. I think ours is usually around $50/yr? Maybe less? That was for a specialty plate.
Impact fees are for new construction, and feel like a good way to pay for the new traffic lights, etc that new developments require and personally I'd love to discourage more people from plowing down the Everglades and building giant developments out there. If impact fees accomplish that the more the merrier. But you could also buy a "used" home and not pay an impact fee if it bothers you so much. They're generally baked into developers pricing for new homes anyhow.
As for real estate being overpriced, we aren't buying at the moment, but it's not so overpiced that we are selling all our investment properties either. And don't forget to file your homestead exemption paperwork if you do buy a house.... so you can get a big "residents only" discount on your property tapxes. (See, those fees and taxes can Be on your side too!)
Compared to the thousands in income taxes we'd be paying in most other states (and it would easily top $10K annually in some states), we've definitely made out very well with Florida and its consumption based tax and fee system compared with an income tax system. So calm down!
