Here’s a snapshot of the Greenwich condo market from 2003 til now, at least for this two-bedroom unit at 15 Palmer Street in Cos Cob. It sold for $350,000 in August ’03, sold again four months later (those were the days) for $545,000, down just a hair from its asking price of $548,000. It came back on in April 2007 asking $695,000 and finally sold last Friday, almost two years later, for $575,000. So what went up, went down. Will the next sale be $350,000? I hope not.
