Split lease? (4)
I believe the answer is:
rent
I believe this clue is a double definition.
'split' is the first definition.
('rent' can be a synonym of 'split')
'lease?' is the second definition.
('rent' can be a synonym of 'lease')
(Other definitions for rent that I've seen before include "Payment due to landlord" , "opening" , "Tear; hire fee" , "Tore apart" , "One due a letter" .)
