Having not met the owners or visited the camps, sadly most similar camps have been closing down or being converted to private camps for many years. The economics of earning a living just don't line up. AMC supposedly bought the three sporting camps on their 100 mile wilderness property from willing sellers who apparently just couldn't make a go of it. The WHL land at one time most likely was James Rivers timberlands (from the Old Town ME mill). There usually were limited options to some camp owners to buy the lots under their camps which were formerly leased lots before the land got transferred. The land is typically under LURP (land use planning commission) jurisdiction. They rank each great pond in the state as a 1, 2 or a 3. A largely undeveloped lake is a class 1 and development is very restricted, basically what is there is "grandfathered" but anything new is very difficult to permit. Usually its nothing new within 250 feet of the shoreline, with only a 10 foot path can be cleared through the frontage and even the path has to be crooked so that no one can see through it from the lake. If there is a structure closer to the lake it can be repaired to the same footprint of what was there. In some cases these camps have been converted to condominiums where an association owns the land and individual own the buildings. Camp Phoenix at Baxter State Park is such a development. It is an inholding in BSP and can only be accessed from BSP.
There have been lots for sale on occasion at West Carry Pond which is partially developed lake east of Bigelow. They usually are in the 200 K range. There are many camps on lease lots in the Katahdin Area. Not many folks want to by them as they are generally difficult if not impossible to get a mortgage, as the owner of the lot has the right to ask the tenant to vacant when the leases are up. One major owner indicated last year that they would be selling their leased lots to the camp owners. Typically, they give the owner a break over retail but not much for many folks who are retired mill workers. I know of one long term camp that was on leased land, the owner of the land contacted the camp owners one year and gave them 90 days to come up with 250 K cash, no negotiating. If they didn't come up the cash they had to remove the camp on their dime. They ended up selling it to real estate agent for 25K and let the agent buy out the lease. The agent then listed the camp for $395K.
A lot on one of these wilderness lakes is extremely rare. I know of a few on similar lakes. Generally they sell for about $1000 per foot of frontage and LURP limits most lots to 250 feet minimum so plan on $250,000 for the lot. Many may have camps but usually they are basically only worth rebuilding to get around the setback provisions.
Many folks probably don't realize that many on these small business owners have zero retirement and may have loans to pay off. Basically unless they can sell the business and the sweat equity they have built up in it, they cant retire or move on. I don't think that's the case with WHL but it is with many of these camps.
