Real property, money also (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
land
'real property' is the definition.
(I know that land is a type of real property)
'money also' is the wordplay.
'money' becomes 'l' (L can mean 'pounds').
'also' becomes 'and' (both can mean in addition).
'l'+'and'='LAND'
(Other definitions for land that I've seen before include "Disembark" , "Light" , "Women farm workers in World War II" , "Lift with ropes and pulleys" , "Capture" .)
