Actual bottom line: government property (4,6)

I believe the answer is:
real estate
'property' is the definition.
(I know that real estate is a type of property)
'actual bottom line government' is the wordplay.
'actual' becomes 'real' (synonyms).
'bottom line government' becomes 'estate' (I can't justify this - if you can you should give a lot more credence to this answer).
'real'+'estate'='REAL ESTATE'
Can you help me to learn more?
(Other definitions for real estate that I've seen before include "US-style spread?" , "Landed property" , "properties" , "land in New England" , "Land in America" .)
