Out of rent for van (9)
I believe the answer is:
forefront
'van' is the definition.
(I've seen this before)
'out of rent for' is the wordplay.
'out' is an anagram indicator.
'of'+'rent'+'for'='ofrentfor'
'ofrentfor' with letters rearranged gives 'FOREFRONT'.
(Other definitions for forefront that I've seen before include "van" , "Vanguard" , "Leading position" .)
