Lousy rental returns housing Welsh girl (5)
I believe the answer is:
nerys
'welsh girl' is the definition.
(I've seen this before)
'lousy rental returns' is the wordplay.
'NERYS' is hidden backwards within the letters.
But, I'm unsure how this is indicated.
'housing' acts as a link.
Can you help me to learn more?
(Other definitions for nerys that I've seen before include "Is it a woman" , "Welsh miss?" , "Welsh girl" .)
