Just so you know, because I didn't.. There is no way to remove a player vendor on your own. Even if you drop the house, the vendor just sits there on the grass. I assumed, from the dozens of idocs I've done with vendors, that they collapse to backpacks in the event your drop the house. This does not happen. Luckily Telamon was able to assist. He mentioned that in a Future Patch™ we would have eviction powers. Until then, I'll keep my own vendors in my own vendor mall.
Ok..... Good info.... These are new players who were occupying the houses in Ocllo when the houses were transferred to me. They lost access. I am trying to locate them to get them access back if they need it, and their possessions back if they don't
