Settled one into residence (4)
I believe the answer is:
paid
'settled' is the definition.
(paying is a kind of settling)
'one into residence' is the wordplay.
'one' becomes 'i' (Roman numeral).
'into' indicates putting letters inside.
'residence' becomes 'pad' (I've seen this before).
'i' put within 'pad' is 'PAID'.
(Other definitions for paid that I've seen before include "Hired" , "Settled the bill" , "Handed over money" , "Settled financially" , "Settled debt" .)
