The Watergate Hotel has been closed since 2007. Monument Realty bought the facility in 2004 hoping to renovate the facility but was forced into foreclosure on the property last week, after it was unable to repay a $40-million loan controlled by PB Capital.

Astrove said in a telephone interview that PB Capital plans to sell the Watergate.
