We have a refinance situation where we're doing an 80/20 loan. Technically, the old loan secured by a dwelling is going to be paid off by the "80" loan, with the "20" portion going to cash out only. I'm thinking that the "20" portion would not be HMDA reportable because we are not paying off a loan in relation to that? I appreciate any help you can give me!

If the "20" part is not satisfying and replacing a lien, nor is it being used for home improvement or the purchase of another property, then yes, I agree - it would NOT be HMDA reportable.
