Everyone saying not to buy a house before you are married, I don’t know, some people never want to get married. Marriage doesn’t always equal commitment, and not being married doesn’t mean not being committed to a relationship. This may vary by state and I would talk with an attorney, but in PA you can title property as tenants in common instead of as joint tenants. Then you both own half of the house, if one person dies, ownership doesn’t automatically transfer to the other owner.
