RE value is all about location and all factors related therein. Ie everything from local legal factors through to view and relative scarcity. RE in constrained places will always have a higher price/sqft than less dense places. The markets also somewhat ensure all the other costs of RE (ie building components like steel, wood, and labor) cost around the same from place to place. But land can’t be arbitrated between localities.
