Borrowers usually pay this attention (8)
I believe the answer is:
interest
This clue is a double definition.
'borrowers usually pay this' is the first definition.
'attention' is the second definition.
(thesaurus)
(Other definitions for interest that I've seen before include "Money paid by borrower" , "Money found in street" , "Growth on capital sum" , "Deposit account gain" , "Benefit" .)
