Why are houses just west of Rancho Sante Fe Road (Rancho Carillo Area) approx $50-$75K higher for the same square footage than Old Creek Ranch/SEH. Is it purely having Carlsbad Address? The schools are the exact same with Old Creek Ranch. I would not think Carlsbad address vs San Marcos Address hold a that much of a premium in the market place, but current pricing shows this. Any thoughts?
