1. (1) a federal Section 8 contract will expire;
2. (2) the landlord will exercise the option to terminate or not renew a federal Section 8 contract and mortgage;
3. (3) the landlord will prepay a mortgage and the prepayment will result in the termination of any federal use restrictions that apply to the housing; or
