US state where I had a house (5)
I believe the answer is:
idaho
'us state' is the definition.
(I've seen this before)
'i had a house' is the wordplay.
'i had' becomes 'id' (I'd).
'house' becomes 'ho' (abbreviation for house).
'id'+'a'+'ho'='IDAHO'
'where' is the link.
(Other definitions for idaho that I've seen before include "The Gem State (US)" , "Northern US state" , "Pertaining to the Bard" , "agricultural land" , "US state, capital Boise" .)
