'It's unfathomable': A San Francisco home worth $1.8M was just listed for $488,000 -- but there's a big catch

In Russian Hill, San Francisco, a $1.8 million Edwardian-style home is listed for $488,800, but buyers can't move in for 30 years due to long-term tenants paying low rent. The property will be sold as-is with the tenants.
