To the best of my knowledge, based upon the posts in this thread, I am the only one who has participated and who actually lived in a lake community in which I had deeded exclusive use of a common area boat dock.
As the lake and entire shoreline was owned by the public utility that built the dam that flooded the farms that created the lake to begin with, I can assure you beyond any doubt that those property owners whose lots abutted the public utility-owned land upon which the lake shore was located paid a hell of a lot of money for the right to use that frontage which was not actually within the legal boundaries of the parcel in which they owned fee simple interest and that I and others paid more for a non-"lakefront" lot which came with the deeded exclusive use of a common area boat dock than we would have paid for a similar lot which did not include that deeded exclusive right of use of a boat dock. And financing was never, ever, ever a problem.
The right of use is not personal property. It is a stick in the bundle of rights associated with real property. I did not "own" the dock. It was "owned" by the Homeowner's Association. I did have deeded exclusive use of the dock, via my ownership of a lot to which the deeded exclusive right of use was assigned, and was responsible for maintenance in exchange for that exclusive use. The parcel of land upon which I built my home had higher value as a result of deeded exclusive use of that dock that an otherwise identical parcel lacking that deeded exclusive right of use of a dock would not have.
But...but...but...
Try telling me that an access easement across a property which fronts a public roadway adds no value to a parcel located behind that fronting property which would otherwise be landlocked without that easement.
Same-same.
