Check
Johnson's Cove under the search function here for several years of
background. The signs have been up for
two years, BTW.
A few years ago a developer bought nearly all of the cove (plus a few lots around the corner) for $3½-million.
One lot is for sale at $4¼-million, faces away from the view, and is boggy-soggy.

To my inquiries ten years ago, all the conservation folks responded "not interested" about conserving it. One ad describes a
bargain lot, at nearly $900K. (At John
son -- no "s" -- Cove Lane).
Years ago, most of those tranquil lots would have been described as "unbuildable", but all that has changed in recent years. Directly upslope from those lots is a 20-unit communal septic tank, dynamited into of the huge rock ledge that forms the uphill side of Johnson's Cove. Since the rest of Wolfeboro Neck is all moraine rock or clay "soil", that rock ledge may have stood against the glaciers and allowed the formation of all of the Neck out to the Broads! (My guess).
With the housing slowdown, the developer has built only one demo building
off-shoreline in the last two years; however, prices may fall on the shorefront lots as a result.
To add a few years of tranquility, you'll have to make an offer!
