Therefore, rural property incomplete until now (2,3)
I believe the answer is:
so far
'until now' is the definition.
(both can mean up to the current point)
'therefore rural property incomplete' is the wordplay.
I cannot really see how this works, but
'therefore' could be 'so' ('so' can mean 'consequently' or 'therefore') and 'so' is present in the answer.
'property' could be 'r' (r is a kind of property) and 'r' is located in the answer.
The remaining letters 'fa' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for so far that I've seen before include "To this point" , "till now" , "to a certain degree" , "Up until the present moment" .)
