Mortgage-related insurance premiums required by the creditor are those described in § 1026.35(b)(3)(i) and its commentary, except that, for purposes of § 1026.37(c)(4)(ii), mortgage-related insurance premiums do not include mortgage insurance premiums disclosed pursuant to § 1026.37(c)(2)(ii). A creditor need not include premiums for mortgage-related insurance that are not required as part of the legal obligation or under applicable law, such as optional earthquake insurance or credit insurance, or fees for optional debt suspension and debt cancellation agreements.
