Hence the concern.

Property behind me, 2-6 acre lakes with nice house between them, 40 acres, sold for $370K. The adjacent property to the west, owned by a hydro engineer who hit it big, built out 3 lakes, lined them with stone, fountains, copper roofed gazebos, bronze fountains and created a botanical retreat with a religious theme. Beautiful, albeit overdone, had to be millions. Passed away, perhaps his tome, no longer a retreat, now a private residence, sold with 50 acres at the depth of the downturn a few years ago for just under $600K. I expect it will be developed someday, he's had developer inquiries. I own the valley next door.
