Loaded or poor in fabulous location (8)
I believe the answer is:
eldorado
'fabulous location' is the definition.
'eldorado' can be an answer for 'location' (eldorado is a kind of location). I am not certain of the 'fabulous' bit.
'loaded or poor' is the wordplay.
'poor' is an anagram indicator.
'loaded'+'or'='loadedor'
'loadedor' with letters rearranged gives 'ELDORADO'.
'in' is the link.
Can you help me to learn more?
(Other definitions for eldorado that I've seen before include "source of wealth" , "The golden land?" , "city, apparently lost" , "wealthy location" , "city of riches" .)
