Figure how much property I'm coming into (8)
I believe the answer is:
estimate
'figure' is the definition.
(I know that figure can be written as estimate)
'much property i'm coming into' is the wordplay.
'much property' becomes 'estate' (estate is a kind of property. I am not sure about the 'much' bit.).
'coming into' means one lot of letters goes inside another.
'estate' placed around 'im' is 'ESTIMATE'.
'how' acts as a link.
Can you help me to learn more?
(Other definitions for estimate that I've seen before include "Calculate roughly" , "'Judge, calculate (8)'" , "Reckon, guess" , "Judge the approximate value" , "Judge the worth of" .)
