Regards foreign money as a blot on the landscape (7)
I believe the answer is:
eyesore
'a blot on the landscape' is the definition.
(I've seen this before)
'regards foreign money' is the wordplay.
'regards' becomes 'eyes' (I've seen this in another clue).
'foreign money' becomes 'ore' (I've seen this before).
'eyes'+'ore'='EYESORE'
'as' acts as a link.
(Other definitions for eyesore that I've seen before include "Ugly structure" , "Horrible sight" , "bad sight" , "Thing that is ugly to look at" , "Monstrosity" .)
