Major cities like San Francisco have hit headlines amid concerns their urban districts are in the grip of a doom loop - but a new report revealed the city where an even worse crisis is unfolding in its decaying downtown. Take the city's largest office building for example. In 2006 this prime real estate sold for $205 million. But that same now vacant skyscraper recently sold for around $3.5 million - a shocking 98 percent drop in value in less than two decades, the outlet reported. The Railway Exchange Building, once the crown jewel of downtown, is also now an empty relic with peeling paint.
