Again close to getting the right lease, possibly (6)
I believe the answer is:
reseal
'again close' is the definition.
('seal' is an answer for 'close' so perhaps 'reseal' is OK for 'again close')
'getting the right lease possibly' is the wordplay.
'getting' means one lot of letters goes inside another.
'the right' becomes 'r' (common abbreviation).
'possibly' is an anagram indicator.
'lease' anagrammed gives 'eseal'.
'r' going inside 'eseal' is 'RESEAL'.
'to' acts as a link.
(Other definitions for reseal that I've seen before include "Close again tightly" , "Close securely again" .)
