A successful clothing department store, in a central downtown location of a certain city, is of a limited size and has grown so much over the past year that it needs to expand. There are a few other slightly larger available retail lots in the downtown regions for sale, but the prices per square foot are quite high.

Which of the following, if true, most seriously undermines this plan?
