It's the arrangement for payments (6)
I believe the answer is:
tithes
'payments' is the definition.
The definition and answer can be both related to property as well as being plural nouns.
Maybe you can see a link between them that I don't see?
'it's the arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'its'+'the'='itsthe'
'itsthe' anagrammed gives 'TITHES'.
'for' is the link.
Can you help me to learn more?
(Other definitions for tithes that I've seen before include "Tenth parts, levied by a church perhaps" , "Church taxes" , "Levies of one tenth" , "Levies of one-tenth, to church perhaps" , "Tenths of income given to church" .)
