Lot 325 was listed For Sale last year and failed to sell at $29,000. There are now just two lots that are active For Sale in the area both listed around $50,000. The last lot that actually Sold in Cold Springs area was back in March of 2010.
My professional opinion is that the lot is worth somewhere between $20,000-$25,000.
