Lease again (5)
I believe the answer is:
relet
'lease again' is the definition.
('let' can be a synonym for 'lease' so perhaps 'relet' is OK for 'lease again')
This is the entire clue.
(Other definitions for relet that I've seen before include "Lease the property again" , "Rent out (room) again" , "Grant tenancy again" , "take in new tenant" , "have another tenant" .)
