Quick answerHawaii sells redeemable tax deeds for unpaid property taxes. Lien buyers can earn 12% per year — interest paid by the redeeming taxpayer to the purchaser on redemption (HRS §231-67); this is redemption interest on a deed purchase, not a lien-certificate rate. Redemption: 1 year after the sale to redeem from the purchaser (or 1 year from recording if the deed is not recorded within 60 days after sale), paying purchase price plus costs and 12%/yr interest (HRS §231-67). Sale may occur once the tax lien has existed for 3 years (HRS §231-63). Sales: Each of the four counties holds its own sale, typically annually in spring — e.g. Honolulu and Maui sales in May, Hawaii County sales in January and June in some years Governing law: Hawaii Revised Statutes §§ 231-62 to 231-67 (sale §231-63; deed and redemption §231-67), implemented by county codes/ordinances (e.g. Maui County Code 3.48.250; Revised Ordinances of Honolulu §§ 8-5.1 to 8-5.9).
