Big deal; this happens even if an anchor store moves to a better location in town, which happens quite often in my town. My problem is that it creates blight—the unused building with “acres of free parking” become a magnet for bums and other undesirables and consumes acres of real estate that could be used for better use.
These are called “triple net leases” and they are an excellent investment (usually), but you have to be a “big guy” in order to have the funds to do it.
