I actually lived in Orlando for 4 years and my family and I loved it there. There is tons to do, lots of great community parks if you're into that. Everything from dining, shopping, and fun is all close by.
I lived out East of Orlando, in the Waterford Lakes area and loved it there. Of course though it's been 2 years since I sold my home there and there has been a huge real estate boom so the price of homes has gone up considerably. Property taxes ran us about $4000 annually. Sales tax was about 7.5% if memory serves me. You can get much more home and property for you money by going outside the city and or county lines. When we left you could still get property at a decent price in areas such as Sanford, Titusville, and Oviedo. If you want to get out in a more rural area but still be close to Orlando there are areas such as, Bithlo, Christmas, Leesburg and Mount Dora, or Wildwood.
in the area that I lived (Waterford Lakes) were all grade A schools. It's close to one of the main highways that gets you from one side of town to the other, but there is tolls to deal with.
I don't know much about the hospitals though, as I didn't work when I was there for the 4 years, I was staying at home with my kids.
There are lots of hospitals to chose from in the Orlando and surrounding areas, you have....
Lucerne Medical Center
Arnold Palmer (women's & children's)
Florida Hospital (has several locations through out the area)
Winter Park Memorial
Central Florida Regional
Parish Medical Center
South Lake Hosp (Clermont, FL)
Osceola Regional Medical Center (Kissimmee, FL)
....to name a few.
Good luck in where ever you decide to go. Orlando is nice if you like a larger town with lots of things to do. But if you like more of a small town feel then there are those areas close by that you still have room to breath.
