I'm a little stuck... Click here to teach me more about this clue!

'money' is the definition.
The definition and answer can be both related to property as well as being singular nouns.
Maybe they are linked in a way I don't understand?

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for revenue that I've seen before include "stream, perhaps" , "Takings" , "Earnings" , "Money received" , "Tax for the government" .)

I've seen this clue in the Evening Standard.
