Vrbo's advertised slogan is "Beach House, Condo, Cabin and more..." There are over 25+ dwelling types in the booking filters; e.g., barn, boat, etc. It's never been just traditional homes.
As far as ranking, a future traveler may look at this trailer listing, but book yours. Then your ranking will go up. It all evens out IMO. I don't mind that a Won/Lost card shows a different type of property because it gives me insight into what travelers are looking at and keeping up on trends and being aware.
