There aren't that many thousands of homes on the 30A corridor. I still talk to people who are entering retirement and are doing the property search now. There is a regular influx of people buying and I think the vacation market continues to develop. Permits are way, way, way off as well.
I searched the public MLS site for the followinging areas: South Santa Rosa Beach, S. Walton West and S. Walton East. The following are the numbers returned:
Single Family Homes: 1,331
Condos: 1,417
Townhomes: 163
Land: 1,127
Fractional Ownership: 39
It appears that S. Walton West includes Sandestin (?) so the numbers may be skewed a bit.
I don't remember the annual demand numbers but that seems like a lot of properties on the market. It is also my sense that most properties are overpriced so there is a reckoning to be had in this market.
