Isolated home recently found in south of France (9)
I believe the answer is:
insulated
'isolated' is the definition.
('insulate' can be a synonym of 'isolate')
'home recently found in south of france' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'recently' becomes 'late' (of late).
'found in' is an insertion indicator.
'south of france' becomes 'sud' (French for south).
'late' inserted within 'sud' is 'sulated'.
'in'+'sulated'='INSULATED'
(Other definitions for insulated that I've seen before include "cut off from elsewhere?" , "Protected" , "liable to be shocking? On the contrary" .)
