Where is to rent, apart from that? (9)
I believe the answer is:
otherwise
'apart from that?' is the definition.
(I've seen this before)
'where is to rent' is the wordplay.
'rent' indicates anagramming the letters (rent can mean torn or damaged).
'where'+'is'+'to'='whereisto'
'whereisto' anagrammed gives 'OTHERWISE'.
(Other definitions for otherwise that I've seen before include "As an alternative - like white rose" , "In other respects or ways" , "White rose (anag.)" , "Under different conditions" , "Apart from that" .)
