Newly-built homes - and so attractive (8)
I believe the answer is:
handsome
'attractive' is the definition.
(I know that handsome is a more specific form of the attribute attractive)
'newly-built homes and' is the wordplay.
'newly built' indicates an anagram.
'homes'+'and'='homesand'
'homesand' anagrammed gives 'HANDSOME'.
'so' acts as a link.
(Other definitions for handsome that I've seen before include "beautiful" , "Fine-looking" , "Easy on the eye" , "'Good-looking, as a man might be (8)'" , "Nice-looking" .)
