Right now, there is a lot of new construction going on in the Sarasota Area. Problem is, houses generally don't appear on the MLS until they are built and on the market, and builders of new developments generally don't build houses before they are committed to by buyers, so it's not easy to keep up with what's available.
There are new communities being developed right now in the Fruitville-Palmer Blvd. area, The Honore Extension, and, of course Lakewood Ranch. There are also smaller neighborhoods going up closer in to the city. I have that information for you along with knowledge of the builders and the neighborhoods.
Have a great day!
