And coo, look what we’re having to pay! (4)
I believe the answer is:
bill
'pay' is the definition.
The answer and definition can be both related to property as well as being singular nouns.
Maybe you can see a link between them that I don't see?
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bill that I've seen before include "American banknote; man's name" , "The fellow" , "Circular - account" , "Promontory; beak" , "Notice - printed advertisement" .)
