OK - very long response...
My husband and I moved here from Massachusetts for much the same reasons you are considering. When we first arrived it was like living a vacation in paradise! For me it still is - I've been running around with the roof off my little convertible (KIA - no Mercedes for me!), with shorts and a t-shirt and its January! Got to love it! Yes there will be a cold spell but it will pass quickly and it means no air conditioning, all the sliding doors wide open, dinner out on the patio every night - its gorgeous right now. And since I love summer the heat doesn't bother me a bit! I love Hollywood!!! Love to wander around the downtown shops, love the boardwalk and the beach, love the parks, love my neighborhood with big, old trees and large lots! Love Mardi Gras and music on the beach and the festivals every other weekend. Plus it is mid-way between Fort Lauderdale and Miami, 1 hour to West Palm and 1 1/2 to Key Largo! Flights to everywhere are available and tend to be fairly reasonable - so if we need to visit the folks or the kids its a quick trip away. And we love cruising - since the terminals are right here we get great local and last minute rates. AND OF COURSE - the diving is the best! Miami has great wrecks, Broward County as well and excellant beach diving, the Keys - well no need to explain, and Palm Beach drift diving!
On the other hand.... Hubby hates it here for all the reasons presented by others. The traffic is a pain - learn the sideroads! And don't be in a hurry to get anywhere! You have to make a special effort to meet people and make friends. (Took me almost eight years to get to know my neighbors and I'm an outgoing person. However, you will meet lots of great people on the board and have a base right there.) It is very hot in the summer for people who do not tolerate heat and humidity well. Home prices, taxes, insurance, gas, groceries - everything is expensive compared to other areas. (But the houses can be kinda cool! - Mine is sorta an L-shape and looks small from the front but every room on the back opens through big sliders onto the patio and pool. Big pass-through windows with bar seating is the norm.) There is a lot of crime and poverty in some areas but most of the crime stays in those areas. Where we live there has not been a major crime in the eight years we have been here. Some car thefts and some minor vandalism but not breakins, murders, or other major crimes that I am aware of.
Hurricanes? Well Florida is home to more hurricanes than any other state. Plus we get massive thunderstorms in the summer that yeild flooding, lightening strikes and spawn tornadoes. The dry season sees huge fires in the everglades. This is why my husband is insisting we leave. Doesn't bother me as much as does him. This year's hurricanes cost us our pool enclosure but it was old and needed replacing (silver lining), it trimmed alot of trees that needed trimming (silver lining), and the extra we will get from insurance will replace our old appliances (big silver lining). After all that is what insurance is for! Yes, some people lost a whole lot more - mostly multi-unit facilities and older homes or homes with older roofs. A worse hurricane would concievably do more damage. The power outage was an inconvenience but I kinda enjoyed it - everyone got to meet their neighbors and acts of kindness were everywhere. Pick your house wisely - hurricane shutters are a must and should be up to current code, make sure the roof is new and check the construction for code as well, don't buy east of 95 even to be near the beach - prices are higher and insurance is twice!, check to see if you are in a flood zone - much of Hollywood isn't but big areas are.
Enough for now. Hope this helped. If I was being given a choice I would not be leaving! Ever! But that's what marriage is all about.
Let us know what you decide. Come for a visit and we'll show you around!
