Housing area in eastern land (6)
I believe the answer is:
estate
'housing area' is the definition.
(I've seen this before)
'eastern land' is the wordplay.
'eastern' becomes 'e'.
'land' becomes 'state' (synonyms).
'e'+'state'='ESTATE'
'in' acts as a link.
(Other definitions for estate that I've seen before include "Housing area" , "Group of suburban houses or industrial units" , "Amount of land - type of car" , "Land with buildings" , "What you leave when you die" .)
