Foreclosure of reverse mortgage home. What are the next steps?

There was a sign posted on my mom’s house yesterday saying “this property is being managed by so & so field company”.

I'm assuming this is a company contracted by the reverse mortgage company’s bank to perform an (exterior) inspection so I’m wondering what the next steps are regarding when & how the bank takes physical possession of mom’s house.  Since they haven’t contacted me (I’m her POA for everything) how will they get inside the house?
