Rancho Santa Fe Homes For Sale and market update from Lucy Kelts, Realtor. Lucy Kelts is the luckiest person in the world! I have the privilege of living (I live in Fairbanks Ranch) and working (I sell real estate) in Rancho Santa Fe. I am passionate about Rancho Santa Fe real Estate and the RSF lifestyle and love bringing others into my world. It is a pleasure to introduce all that RSF offers: top schools, every sport activity, accessibility to fine restaurants, world-class shopping, the PACIFIC OCEAN, easy access to airports, trains, etc. and a quality of living that is unparalleled. And I love living and working with the coolest people who know they, too, want to live in paradise.
