Get better real estate business with five central properties (7)
I believe the answer is:
recover
'get better' is the definition.
(synonyms)
'real estate business with five central properties' is the wordplay.
'real estate' becomes 're'.
'business' becomes 'co' (short for company).
'with' is a charade indicator (letters next to each other).
'five' becomes 'V' (Roman numeral).
'central' indicates the central letters.
The centre of 'properties' is 'er'.
're'+'co'+'v'+'er'='RECOVER'
(Other definitions for recover that I've seen before include "comeback" , "Rescue" , "Get better - get back" , "Bring back" , "Find" .)
