Having a consecrated property husband let (8)
I believe the answer is:
hallowed
'having a consecrated property' is the definition.
(hallowed means consecrated or made holy)
'husband let' is the wordplay.
'husband' becomes 'h' (abbreviation).
'let' becomes 'allowed' (to allow something is to let it happen).
'h'+'allowed'='HALLOWED'
(Other definitions for hallowed that I've seen before include "Consecrated, blessed" , "Honoured as holy, having lewd halo" , "Made holy and honoured" , "Consecrated, holy" , "Honoured as holy like 1 Down" .)
