Redfin mingles MLS-listed homes with FSBOs, foreclosures

Web site displays addresses of bank-owned properties

Seattle-based real estate brokerage company Redfin has integrated foreclosure properties and for-sale-by-owner properties with its map-based search, and the company identifies the various property types with different icon colors and in detailed descriptions.

While some multiple listing services prevent this so-called "co-mingling," or side-by-side display of multiple listing service data with other data sources in property searches, Redfin officials say they believe their added search capability is compliant with MLS rules.
