Let team in for householder (8)
I believe the answer is:
resident
'householder' is the definition.
(thesaurus)
'let team in' is the wordplay.
'let' becomes 'rent' (I've seen this before).
'team' becomes 'side' (I've seen this before).
'in' is an insertion indicator.
'rent' enclosing 'side' is 'RESIDENT'.
'for' acts as a link.
(Other definitions for resident that I've seen before include "one in the house?" , "One living in the place referred to" , "Liver" , "Someone with a home" , "Inserted by permanent inhabitant" .)
