Postal Realty Trust

The rent comes from a tenant backed by the United States government, spread across more than 2,150 properties. Post offices rarely move once they are set up, because relocating a mail route is a real headache. That makes these rent checks unusually predictable.

The portfolio has climbed past 2,150 buildings, up from roughly 2,000 not long ago, and revenue grew about 25 percent over the past year as they kept buying more locations. Profit margins sit near 16 percent, and the company still pays a quarterly dividend.

Every one of those 2,150 plus buildings leans on the same tenant, the US Postal Service. If Congress squeezes postal funding or changes how mail gets delivered, there is no backup tenant waiting in the wings. Concentration like this cuts both ways.

The chief financial officer is leaving after four and a half years to join a private real estate firm, and the company president is filling in on an interim basis during the search. At a company worth under 900 million dollars, one open executive seat carries more weight than it would at a giant.
