Qualified mortgage interest includes interest and points you pay on a loan secured by your main home or a second home. Your main home is where you live most of the time, such as a house, cooperative apartment, condominium, mobile home, house trailer, or houseboat. It must have sleeping, cooking, and toilet facilities.

Note that it's interest and points YOU pay on a loan secured by YOUR home.
