50% off rent, wealthy charged again (8)
I believe the answer is:
reloaded
'charged again' is the definition.
('loaded' can be a synonym for 'charged' so perhaps 'reloaded' is OK for 'charged again')
'50% off rent wealthy' is the wordplay.
I cannot quite understand how this works, but
'wealthy' could be 'loaded' (synonyms) and 'loaded' is present in the answer.
The remaining letters 're' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for reloaded that I've seen is " Dead role (anag.)".)
