Kauai, Hawaii

For most, living in Hawaii may not be a reasonable option, but those that can splurge should definitely take it up as an option. For the sake of mentioning the obvious, living in Hawaii is living in paradise. Kauai serves as a good medium when it comes to amenities, cost of living, and recreational opportunities among all the Hawaiian Islands. Golfing, hiking, beaches, water sports, etc. will keep you busy. The crime rates are also well below the national average.
Con: As mentioned before, living in Hawaii is not a budget friendly option; the cost of living is high and the average house costs over $425,000. Being away from the mainland might be a turnoff for some.
