Bustle around to make renting arrangement (6)
I believe the answer is:
sublet
'renting arrangement' is the definition.
(sublet is a type of rent)
'bustle around' is the wordplay.
'around' indicates an anagram.
'bustle' is an anagram of 'SUBLET'.
'to make' acts as a link.
(Other definitions for sublet that I've seen before include "Rent all or part of a rented property to another person" , "Lease all or part of a rented property to another" , "get help to pay the rent, maybe" , "Rent out to a third party" , "Rent out an already-rented premises" .)
