Much of Honolulu is being purchased by Chinese interests, causing a huge runup in prices and increasing inability of local people to buy homes.
Congress has been quietly considering passing legislation (”CFIUS Section 721”) that would ban China and other foreign nationals from buying real estate in much of the U.S., but it is probably too late and may be deemed unconstitutional as racially discriminatory. Among other things, on Oahu it would require all foreign purchases of real estate to be approved by the President and the Department of Defense. Again, probably too late since China is in the process of buying up much of the U.S.
