Homes were rebuilt but the location's vague (9)
I believe the answer is:
somewhere
'the location's vague' is the definition.
(I've seen this before)
'homes were rebuilt' is the wordplay.
'rebuilt' indicates anagramming the letters.
'homes'+'were'='homeswere'
'homeswere' with letters rearranged gives 'SOMEWHERE'.
'but' acts as a link.
(Other definitions for somewhere that I've seen before include "uncertain regarding place" , "location's vague" , "In an unspecified place" , "Bernstein classic" , "'. . . . . . . . . Over the Rainbow' (song)" .)
