Something good to have (5)
I believe the answer is:
asset
'something good to have' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for asset that I've seen before include "A thing of value" , "Item of value or advantage" , "Useful or valuable quality or possession" , "A possession of some value" , "Someone or something of value" .)
