This final rule provides that units owned or substantially controlled by a public housing agency (PHA) are eligible for purchase under the Housing Choice Voucher Program homeownership option. The inclusion of PHA-owned or controlled properties among properties eligible for purchase under the homeownership option will expand the availability of housing and affordable homeownership opportunities for voucher families participating in the homeownership option. The final rule also establishes procedures to remove potential conflicts of interest where the PHA is the seller. These provisions are modeled on the requirements for PHA-owned units in the voucher rental program. The final rule follows publication of an October 28, 2002, interim rule. After consideration of the issues raised by the single public commenter on the interim rule, HUD has decided to adopt the interim rule without change.
