Would anyone out there know:
If the person holding the life estate is living in the home and the file estate is included in the vesting on the title work, would this be considered owner-occupied for HMDA purposes?

??? I don't understand '...the file estate is included in the vesting on the title work'.
How does it read exactly?
And who is the borrower on this loan?

I believe yes for owner occupancy as the life estate owner is the owner until their death. However, I would find out if the life estate owner has the right to mortgage the property without permission of the " remainderman" who will inherit. That is one aspect often restricted when you put your property into a life estate.

The title vests:
Remainderman and remainderman, husband and wife and the Life Estate interest of Our Borrower, by virtue of a Quit Claim Deed dated...

The borrower is the life estate interest person.

Hopefully legal counsel reviewed how this is being done, to make sure that you are properly secured?

Hopefully, is right!
Thanks for your feedback Kathleen
