Redfin has unveiled a new feature that CEO Glenn Kelman says brings real estate agents "back to an online realm we were banished from a dozen years ago" by helping co-buyers and their advisors collaboratively search with real estate agents for listings. Anyone searching listings on Redfin.com or through Redfin's iPhone or iPad search apps can use " Shared Search " to save, share and comment on listings with a partner, spouse, friends, family or real estate agent.
