Real Estate Data & Charts
You may have noticed a large drop in the # of total active listings in the Manhattan housing data tool & charts today. The reason is because one of the listing providers to Streeteasy.com (who powers the data), adjusted and enhanced their website to more accurately reflect current active listings. Needless to say it contained a good amount of out of date listings that were removed. This is why data and charts are in BETA testing for another 4-5 months or so. Streeteasy is working very hard on data accuracy and timeliness on their end, but at times is at the mercy of the brokerage firm's site; meaning the data they get is only as accurate as the agent at the brokerage who updates the listing. Working with each firm on accuracy, quality control and data feeds is tedious.
I can tell you from starting The HotSpot Haven, way back in 2002, that cleaning data and getting a collection system that works (I have over 100,000 hotspots from over 250 providers) with so many different types of sites and data sources is not only very difficult, but very timely. It's an ongoing process and I for one appreciate what Streeteasy is trying to do for a market without an MLS system. For the data they provide for UrbanDigs, they will let me know when the platform is enhanced enough to take charts out of BETA. In the meantime, you will see discrepancies like today in reported data. In the longer run, you will have a more accurate tool for monitoring trends. Please be patient.
