Natalie and Ted, who are both 40, meet with an insurance agent to discuss their life insurance needs. They have four major concerns. Their first concern is that Natalie is the primary income earner: if something happened to her, Ted would not be able to provide their two young children with the life they are accustomed to. Their second concern is that if something were to happen to Ted, Natalie would have to pay for childcare. The third issue is that they want to make sure the mortgage on their primary residence is paid off in the event something happened to either of them. Lastly, Natalie is concerned about the tax liability on the family cottage when it gets passed on to the kids. The family cottage is fully paid. The agent notes that most of the couple's concerns could be addressed with term life insurance products.

Which of their concerns can only be addressed with a permanent life insurance product?
