JoJo,
Another realtor with a lot of information is
http://sallylovesells.com/
I have not used them, but I did ask them a couple of questions and they were cooperative.
The classified section of the DAILY SUN does not show the daily open houses that are paid advertisements posted every day by The Villages. I was annoyed that I hadn't discovered that until I got there in person. It would have given me a lot more insight. These open houses are for NEW and RESALE. They last for two hours every day in a number of places. Also, I THINK I found out that the developer releases a number of houses in bunches after they are finished, it was just luck that we found ours with a view of the rec center which suits us to a T. They do not build for you AT ALL. You can buy any of the houses that are finished or a resale. I found out too, that a lot of resales are villagers moving from one house to another, VERY common.
The rep we had was not particularly eager to show resales. I don't know that for sure, but sensed it.
It helps too to be somewhat familiar with the models. I concentrated on Ranches and Designers that we were interested in and learned very little about the villas or Premiers. (All of our rich uncles frittered their wealth away) :

I printed out the floor plans from Lyle Gant's site and arranged them in order of size and divided them between frame and stucco. I put them in a notebook. THAT helped a lot.
ALSO. Get the five dollar street map that you can only buy there. It was invaluable.
