HUD 223(f) Express Lane: the CMS part
HUD gives 223(f) applications queue priority when the facility has CMS overall and health inspection ratings of at least 2 stars and no abuse icon, among other tests (ORCF criteria of March 31, 2026). Abbey Senior Health does not meet it today: the abuse icon. The loan-to-value, coverage and operator tests depend on the deal. All the criteria.
