Mancunian Mercantile Investment has bought the 8,904 sq ft Wilmslow Post Office. The site was purchased from private family ownership for an undisclosed sum.
The purchase is one of a number of investments Mancunian Mercantile has made in the town over the last few months.
The property is let in its entirety to the Royal Mail Group until 2021, at a rent of £50,000 a year.
Charlie Williams of Williams Commercial Property Consultants acted for the purchaser. He said: "The property offered an ideal opportunity to purchase a building let to an excellent covenant right in the heart of the town. The investment adds to the growing property portfolio owned by MMI Limited in the North West."
