24 CFR § 92.255 - Converting rental units to homeownership units for existing tenants.
(a) The participating jurisdiction may permit the owner of HOME-assisted rental units to convert the rental units to homeownership units by selling, donating, or otherwise conveying the units to the existing tenants to enable the tenants to become homeowners in accordance with the requirements of § 92.254. However, refusal by the tenant to purchase the housing does not constitute grounds for eviction or for failure to renew the lease.
(b) If no additional HOME funds are used to enable the tenants to become homeowners, the homeownership units are subject to a minimum period of affordability equal to the remaining affordable period if the units continued as rental units. If additional HOME funds are used to directly assist the tenants to become homeowners, the minimum period of affordability is the affordability period under § 92.254(a)(4), based on the amount of direct homeownership assistance provided.
