Money going inland? (7)
I believe the answer is:
revenue
'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" .)
