With the exterior a write off don't move (4,5)

'with the exterior a write off don't' is the definition.
I know nothing about this answer so I can't judge whether this works.

'move' is the wordplay.
I cannot really see how this works, but
'move' could be 'wait' (waiting is a kind of moving) and 'wait' is present in the answer.
The remaining letters 'there' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
