Kauai, Hawaii’s northernmost island, is divided into five sections, including the North Shore. One of the North Shore communities is Hanalei, a small town on the edge of the two-mile, crescent-shaped Hanalei Bay, a world-famous surfing paradise set to the backdrop of green inland mountains. Hanalei’s 96714 ZIP Code has some of the priciest residential real estate in Hawaii, the state with the highest median house listing price in the U.S., according to Realtor.com. (News Corp, owner of The Wall Street Journal, also operates Realtor.com under license from the National Association of Realtors.) “You could literally have a $50 million house next to a small cottage that’s worth a million dollars.”
