Some of these places have been taking refugees/asylum seekers for a while, but like you I can't find anything about it, other than it doesn't look obviously closed.  Might be worth checking planning apps for change of use (although not directly usable).

Can't find any open data for the NG23 6RF postcode which applies to the houses behind the hotel. However checking old open OS maps at least some seem to have been built around 2011 when the OS shows the road changing from service to adopted, see: https://os.openstreetmap.org/#zoom=18&lat=53.184522&lon=-0.806358 and select changes April 2010-November 2011.
