(5) Ten percent of the total units of a housing development for transitional foster youth, disabled veterans, or homeless persons to be provided at the same affordability level as very low-income units subject to a recorded affordability
restriction of fifty-five years. As used in this subsection, "total units" or "total dwelling units" does not include units permitted by a density bonus awarded pursuant to this chapter.

(2) Term.
(a) An applicant shall agree to set rents at affordable rent levels and to the continued affordability of all rental units that qualified the applicant for the award of the density bonus for a period of fifty-five years or a longer period of time if required by any applicable construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program.
(b) All for-sale units shall initially be sold at an affordable housing cost and shall remain subject to a resale affordable housing cost restriction for a period of fifty-five years or a longer period of time if required by any applicable construction or mortgage financing assistance program, mortgage insurance program, or other subsidy program. The applicable resale affordable housing cost restriction period shall reset upon each sale of an affordable unit.
(3) Equity Sharing. The city shall require an equity-sharing agreement for all for-sale units, unless such an agreement would be in conflict with the requirements of another public funding source or law.
