You didn't say if you wanted to buy new or resale. If it's a new home, you'll need a villages agent since the new homes are only sold by them, they are not on MLS. Tony Trussler was recommended above, and he was our agent and he is really good. All the new and resale homes and villas by the villages agents are listed on their website
The Villages New Homes and Resales
If you're buying a resale, besides those listed on the villages website, Realtor Lyle Grant lists on his website all the MLS listings
ALL Homes for sale by Realtors should list all the homes on MLS and he has them broken down to type, price, size, etc.
Most of the homes available you can browse from the comfort of your home in New York. That's why it's not uncommon that many have bought their home here sight-unseen. The only listings you won't have are for sale by owner, but you can find many on this website
