Aloha, Ed -- Anyone can invest in Hawaii, including international Buyers. Perhaps what you might be referring to are specially designated Hawaiian Homelands, which are leasehold properties (vs. fee simple). And for the Hawaiian Homelands, there is a minimum Hawaiian blood quantum requirement. And the Big Island is the most affordable island in which to invest.
