Hi there,
Right now you can get a super deal on a house in Florida. the 2 story next to me - JM construction, 3000 sf, 2 yrs old, just went for 149k. thats almost half price!
In the 70's many houses here were built with aluminum wiring...make sure you don't get a house with that. But as far as A/C, you'll probably have to run it year round...and it is the largest consumption of electricity. Our house was built in '89, is 1500 sf, we have a 180g w/ 3 250mh w/vho's 6' 130w ea, and a 80g w/2 250 mh w/2 vho's 4' 110w ea, 2 12g nano's (soon to have 3rd nano), and 28g bow w/2 65w compact and a 55g freshwater.
We run our air 24/7 76 degrees (standard 10sear a/c unit) and our elec bill is avg about 350-370 in the summer. (frame home)
Having said that, I'll say this: I was in insurance for many many years - not personal insurance though - it was ocean marine and also commercial property and inland marine... so my knowlege of personal insurance is limited. BUT I can still tell you that in a coastal county such as many of us are in, its the Insurance and the property tax thats the KILLER- more than the cost of the home....
But my hubby and I say all the time to each other "there is nothing like a perfect Florida evening". The temp drops, the breeze is great...
You got Shamu, you got Disney, and the Orlando Reef Caretakers Assoc (ORCA)...what more could you possibly want???
It is Flippin HOT & HUMID here, but I don't see how you could regret the move....especially with the Ocean Breeze...
