Accommodation debt freaks a band out (3,3,9)
I believe the answer is:
bed and breakfast
'accommodation' is the definition.
(I've seen this before)
'debt freaks a band out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'debt'+'freaks'+'a'+'band'='debtfreaksaband'
'debtfreaksaband' with letters rearranged gives 'BED-AND-BREAKFAST'.
(Other definitions for bed and breakfast that I've seen before include "pension?" , "temporary billet" , "Fed up after retirement" , "Common hotel arrangement" , "Accommodation, hopefully temporary" .)
