Summer Bummer Alert! Fourteen contracts were signed last week at $4 million and above, the 8th-straight week that total luxury sales have fallen below 20. The total dollar volume was $87.56 million, the lowest in 53 weeks. More bad news: No contracts were signed above $10 million, the first time that has happened since the Sandy storm—the week of October 29, 2012. It may not be much, but if you’re looking for a sliver of a silver lining, here goes: Six co-ops went to contract, the best week for co-ops since the first week in June.
