1. Only if you classify them as "home improvement" loans.
2. I don't think you can. This is a refinancing, but it doesn't meet the definition in HMDA (both must be dwelling secured).
3. I'll let someone else answer this one.
This is why I've been encouraging bankers to not report unsecured (or non-dwelling secured) HI loans as HMDA anymore. If you only report dwelling secured HI loans, there is a consistent purpose and collateral test for all types of HMDA loans: home purchase, HI and refinancings all must be dwelling secured.
If you don't go with this: if you are going to report non-dwelling secured HI loans, then you have a problem with the "logic" (I know, I know, I shouldn't mention logic and HMDA in the same sentence). If you report a CD secured HI loan, when it refinances, you can't report it again.
