If you're paying off the original loan with this new loan, then your TRID purpose would be "refinance".
(i) Purchase. If the credit is to finance the acquisition of the property identified in paragraph (a)(6) of this section, the creditor shall disclose that the loan is for a “Purchase.”
(ii) Refinance. If the credit is not for the purpose described in paragraph (a)(9)(i) of this section, and if the credit will be used to refinance an existing obligation, as defined in § 1026.20(a) (but without regard to whether the creditor is the original creditor or a holder or servicer of the original obligation), that is secured by the property identified in paragraph (a)(6) of this section, the creditor shall disclose that the loan is for a “Refinance.”
(a) Refinancings. A refinancing occurs when an existing obligation that was subject to this subpart is satisfied and replaced by a new obligation undertaken by the same consumer. A refinancing is a new transaction requiring new disclosures to the consumer. The new finance charge shall include any unearned portion of the old finance charge that is not credited to the existing obligation. The following shall not be treated as a refinancing:
(1) A renewal of a single payment obligation with no change in the original terms.
(2) A reduction in the annual percentage rate with a corresponding change in the payment schedule.
(3) An agreement involving a court proceeding.
(4) A change in the payment schedule or a change in collateral requirements as a result of the consumer's default or delinquency, unless the rate is increased, or the new amount financed exceeds the unpaid balance plus earned finance charge and premiums for continuation of insurance of the types described in §1026.4(d).
(5) The renewal of optional insurance purchased by the consumer and added to an existing transaction, if disclosures relating to the initial purchase were provided as required by this subpart.
I'm fixin' to fix that.
