Do real estate brokers know where their listings are going? A mobile home search application from banking giant Chase that’s powered by broker-provided listings has renewed the debate.

Listing syndicator ListHub is the primary data source for the app, Chase My New Home, and the app has been downloaded by more than 100,000 people since its November 2012 debut, according to Chase.

The ListHub network has about 127 publishers in its network, some regional, with most brokers able to choose between about 55 or 60, ListHub said.

Using ListHub’s “dashboard,” brokers from about 450 participating multiple listing services nationwide can choose whether to send their listings to specific websites of their choosing; to websites filtered by certain criteria, such as those that contain no for-sale-by-owner listings or remove inactive listings quickly; or to all available publishers with the choice to opt-out when notified of a new publisher added to the network.

A blog post about the app by Brain Boero of real estate consulting firm 1000watt asking about the source of the listings on the app drew varied reactions from industry participants about who should monitor where listings appear, who gets the leads from those listings, and the pros and cons of listing syndication.

Matt Cohen, chief technologist at Clareity Consulting, commented that the app’s listings come from ListHub and said no broker he had spoken with “had any clue.”
