No I'm not talking about real estate. I'm talking about properties of things. Are they things themselves?
That depends on the nature of the property. Colour, size and mass are all properties of an object and they are measurable. You could argue mass is a 'thing' in the concrete sense but colour is an abstract albeit measurable 'thing'. Humans can also conceive of abstract 'things' such as Communism, Love, Hunger and so on, but they do not have any physical aspect that could be considered to be a 'thing'.
From a grammatical point of view, things i.e. nouns can be concrete or abstract. You can stub your toe on concrete nouns but not on abstract ones.
