Unfortunate Wording
At first glance, this message sounds rather ominous. The landlord seems to be saying that not only is he selling the house, but he’s also selling the people within it. But, of course, that would be illegal because people aren’t for sale. Still, it’s a bizarre message.
Once we give a little more thought to his cryptic text, we assume that he means he’s putting the house up for sale while the tenants still live in it. So, actually, it’s a more polite message than we realized at first. He’s warning them that the house will be put on the market but is allowing them to stay there during the sale process. Phew!
