Around my area you are looking at 75,000 to 100,000 per acre maybe more the closer you get to the beach. there was a couple estate auctions this weekend i think. one was 90+ acres in Bishopville Md. about 10 min from me, the other was almost 200 acres on the water. forget where. I'll look and make sure of the dates. I'll edit this post if they have not taken place yet.
Take a look at this
LINK It has 3 parcels in Bishopville each 20+ acres with one on the water.
There is anouther acution, the 2nd one down under upcoming auctions. If anyone is interested in getting a Ward Bros' decoy this would be an auction of intrest.
