I would be curious how the arrangement with KRKO works. Are you required to keep the towers on the site? Do they pay you rent for the land? Do they maintain the towers? That makes a huge difference in terms of who will end up buying the place.
Think about it this way: A similarly-sized house in similar condition in Seattle city limits would cost you the exact same price. The only difference is you get about 7 1/2 additional Acres that hopefully generate revenue via rent or just topple the towers, subdivide it into two additional parcels (I don’t know what the zoning laws are, but 2 Acres for rural residential is reasonable), and re-coop 1/4-1/3 of the closing price.
Unless it’s a sweetheart deal for the buyer with rent, or Andy has a long-term lease for the site, my guess is the buyer will likely knock em down. Let’s just be frank, the housing market for radio geeks in the Seattle area is a bit weak these days. And nobody besides radio geeks want towers nearby. Spoils the view...
