Should Prop Mgr show for the appraisal of a rented property?

[A Sanderlin]

Is it a common practice for the property mgr to NOT be in attendance when a loan appraiser does a walk-through of a rented property? In our specific case, the appraiser contacted us directly for access to an area that our property mgr has keys. Also the property mgr set up the appt. (We live out-of-state.)
