The only time a written application is required by the regulation is when the loan is for the purchase or refinance of the borrower’s principal dwelling and the loan will be secured by that dwelling.
For HMDA, a refi is the replacement of a loan secured by a dwelling with a new loan secured by a dwelling. And as previous discussions have revealed there will be a lot of loans reported that have nothing to do with a HMDA purpose because of this definition.
For Reg B, and this is my interpretation, a refi is for the purpose of reducing the term or interest rate only. Any new money takes it into the purpose of the new money. Therefore if I took out the equity of my home to purchase a boat, HI or whatever and consolidate all that with what I owe on the first lien, I am taking out an equity loan secured by a first lien. The purpose of my loan was not to refinance my home. Again this is my interpretation.
