Need market data? You’re in luck. The already-crowded field of real estate market reports is seeing even more competition these days, as firms that previously sat out of the market-report game get in on the action. William Raveis NYC became the latest brokerage to issue a monthly market report on Oct. 30, joining Douglas Elliman, the Corcoran Group, Citi Habitats and many, many more. A point of distinction for Raveis’s report? It will provide computer-generated predictions for the market’s behavior. For years, major firms have issued monthly or quarterly market reports covering rental and sales. During the downturn, the number of reports soared, as brokers and clients clamored for data. In today’s tight market, the reports are a handy marketing tool, as firms tout their reports as offering unique market insight and analysis. Reports today are far more scientific than when Barbara Corcoran crafted her first, based on a handful of sales, 30-plus years ago, but consistent data is hard to come by. This month, The Real Deal looked at some recent reports from brokerages across the city to see how the numbers stacked up.
