The phrase "vacant stores" typically refers to commercial spaces, such as retail shops or office buildings, that are currently unoccupied and available for rent or sale. These spaces may be located in a shopping center, strip mall or other commercial area. The reason for the vacancy could be due to a variety of factors, such as the previous tenant moving out or closing their business, a change in market demand for the type of business that used to occupy the space, or a decision by the property owner to leave the space vacant until a suitable tenant is found.
