Land again, rent-free (9)
I believe the answer is:
argentina
'land' is the definition.
(Argentina is an example)
'again rent-free' is the wordplay.
'free' indicates an anagram.
'again'+'rent'='againrent'
'againrent' is an anagram of 'ARGENTINA'.
(Other definitions for argentina that I've seen before include "South American country" , "Evita's land" , "Silver country" , "Evita's country" , "Republic" .)
