We had two malls locally that this happened with. Neither mall was as robust with business as it was in its height of popularity, but neither was struggling to a point of closing. One went first; a friend was working there at the time and said the new owners set in and doubled the rent. A few stores paid it, but most moved or closed, if not immediately, soon after. Soon, there were maybe 5 stores left.
The other mall went on for awhile, and then the same group bought them up, too. One by one, the shops left, and now there's hardly anything in that mall, either.
Who benefits from this?
