Deem rent is not right, but settles (10)

I believe the answer is:

determines

'settles' is the definition.
('determine' can be a synonym of 'settle')

'deem rent is not right' is the wordplay.
'not right' is an anagram indicator.
'deem'+'rent'+'is'='deemrentis'
'deemrentis' anagrammed gives 'DETERMINES'.

'but' is the link.

(Another definition for determines that I've seen is " Decides".)

I've seen this clue in The Telegraph.
