This interim 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 interim rule also establishes procedures to remove potential conflicts of interest where the PHA is the seller. Specifically, the interim rule provides that an independent entity must perform certain administrative duties for which the PHA would normally be responsible. These provisions are modeled on the requirements for PHA-owned units in the voucher rental program.
