Get a new bed first for residence (7)
I believe the answer is:
Here is my best explanation:
'residence' is the definition.
'get a new bed first' is the subsidiary indication.
'new' indicates anagramming the letters.
'bed' becomes 'cot' (cot is a kind of bed).
'first' is a charade indicator (letters next to each other).
'geta' is an anagram of 'tage'.
'tage' after 'cot' is 'cottage'.
'for' is the link.
(Other definitions for cottage that I've seen before include "Small house with a single storey", "Small home", "Cheese pie industries all may chase this", "Small one-storied house", "building", "Small single-storey dwelling", "small house", "Modest accommodation", "Country residence" and "Small place".)
