So far, this isn't working out as the owners had hoped

One Indian Chase Drive was brought to market in March 2014, by Tamar Lurie, with an asking price of $20 million. That number has been steadily shrinking but the house refuses to sell, despite a switch in agents (I'd be pissed too). Today it's down to $10.9. 

It's hard to imagine how an experienced agent could be so terribly wrong about a home's value: hard, but not unimaginable, because it happens all the time.
