Yes property sale is a thing. It's a process. Why can that thing not be modelled as a function? Property sales are rather complicated processes so having a class for it could be justified. But OO forces us to do it that way for every tiny operation. It's pure bloat.
It's bloat, until you realise that you need to persist a lot of information about the "thing".
Then you realise that the "thing" isn't actually that little at all.
BTW modern OO has constructs which allow a "Verb"-like structure: Generics. You write logic for a certain class of "things", and your compiler makes sure that what you're doing is actually possible.
