The Island Streets carry a median near $1.94 million per Redfin and represent Fountain Valley's most desirable address, defined by quieter interior streets, larger homes, and a neighborhood cohesion that buyers notice immediately. Homes here trade infrequently and move quickly when they appear, reflecting demand that the listing count never fully captures. The buyer profile is move-up purchasers and established families who have done their homework and identified this pocket as the city's best.
