I'd have to double check, but likely in the very early 2000's as the house was about 5 years old when we moved in and we've been here a little over 11 years. (got a great deal, about a 2000 sq ft home, 4 BR, 2 bath, fireplace, large kitchen, and 1 1/2 acres of land all for just 35K, it is a manufactured home, but still a fantastic deal !)
Our home is next to a forest area and they obviously had to clear out a space to put the house so I'm not sure how much the ground was bulldozed, but the town itself had it's beginnings back in the 1700's so even though our home is not that old, the area has a long history.
