Section 1026.37(a)(10)(I)(B) defines a step rate product as a transaction where the interest rate will change after consummation and the rates that will apply and the periods for which they will apply are known at consummation. You have a step rate product.
Please note the Commentary to Appendix D – 7.iii states, “If the legal obligation for a loan secured by the consumer’s principal dwelling provides that the permanent financing interest rate may adjust when the construction financing converts to permanent financing, and such adjustment to the interest rate results in a corresponding adjustment to the payment, the creditor provides the disclosures pursuant to § 1026.20(c), but not (d), if the interest rate for the permanent phase will be fixed after the conversion.” This means the transaction is an ARM and an ARM rate change notice is needed upon conversion.
