Property to come down (4)
I believe the answer is:
land
This clue is a triple definition!
'property' is the first definition.
(kind of property)
'to come' is the second definition.
(landing is a kind of coming)
'down' is the third definition.
(I know that down can be written as land)
(Other definitions for land that I've seen before include "(Of aircraft) alight" , "Bring or come ashore" , "Lift with ropes and pulleys" , "Part of Germany" , "Ground; country" .)
