That varies widely. I bought 50 acres of half-woods( (that had been logged before the sale) and half-wetlands for $10,000 near Watertown NY. The guy who sold it to me had paid $5000 for it 6 months earlier. Last year I sold it for $45,000. Seems property values went up because of Fort Drum.
I bought 20 acres of 1/2 wetland and woods again in Otsego County, NY last summer. Paid $7800 for it. Well wooded (in the dry section) with century old white oaks and hemlocks.
