'property and stay in it' is the definition.
I can't tell whether this definition defines the answer.

'decided to have' is the wordplay.
'decided' becomes 'settled' ('settle' can be a synonym of 'decide').
'to have' becomes 'own' ('own' can be a synonym of 'have').
'settled'+'own'='SETTLE DOWN'

(Other definitions for settle down that I've seen before include "put down roots" , "Become quiet and orderly" .)
