Housing area in east, say (6)
I believe the answer is:
estate
'housing area' is the definition.
(I've seen this before)
'east say' is the wordplay.
'east' becomes 'e' (abbreviation).
'say' becomes 'state' (synonyms).
'e'+'state'='ESTATE'
'in' is the link.
(Other definitions for estate that I've seen before include "Possessions at the time of death" , "All of one's assets -- 5-door car" , "Extensive landed property (6)" , "all the deceased owned" , "Land with buildings" .)
