I am working on a project where I need to be able to distinguish between one who is offering something for rent, and one who is renting from someone. The phrases used need to be short and concise.
The context is not real estate thus commonly suggested alternatives like landlord or tenant do not fit.
I was thinking maybe rentee could work, thinking it followed the same style as employer versus employee, for example. Some quick googling, however, seems to indicate that rentee is not a valid word, but some people do occasionally use it.
