Notice vacant house to lease for disciple (8)
I believe the answer is:
adherent
'for disciple' is the definition.
(synonyms)
'notice vacant house to lease' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'vacant' means to remove the middle letters (a vacant or emptied out form of the word).
'to lease' becomes 'rent' ('rent' can be a synonym of 'lease').
'house' with its middle removed is 'he'.
'ad'+'he'+'rent'='ADHERENT'
(Other definitions for adherent that I've seen before include "Supporter, follower" , "sticker" , "Supporter; sticking" , "Dedicated supporter" , "Sticking; partisan" .)
