Overtly sad about the rent? (7)
I believe the answer is:
tearful
'overtly sad about the rent?' is the definition.
I can't judge whether this definition defines the answer.
'overtly sad about the rent?' is the wordplay.
'overtly sad' becomes 'ful' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' is a charade indicator (letters next to each other).
'the rent?' becomes 'tear' (rent is a kind of tear).
'ful' put after 'tear' is 'TEARFUL'.
Can you help me to learn more?
(Other definitions for tearful that I've seen before include "visibly distressed" , "Visibly upset" , "Weepy" , "Lachrymose, blubbering" , "emotional" .)
