What event can lead to default in addition to missed payments?

The correct choice is associated with title problems, as these can indeed lead to default on a loan or mortgage. Title issues may indicate legal complications related to ownership of the property, which can complicate the borrower's ability to secure additional financing or refinance, ultimately resulting in missed payments or an inability to fulfill the loan agreement.

Title problems can arise from various sources, such as liens, disputes over ownership, or unresolved claims on the property. When these issues occur, they can create significant barriers to the borrower’s financial responsibility. If a borrower is unable to resolve these title issues, they may find themselves in a situation where they cannot sell or manage their property, leading to financial distress and potential default.

While missed payments are the most straightforward cause of default, the underlying factors that might cause financial strain, such as problems with the title, can escalate the situation, increasing the risk of falling into default. Other choices like a change of address, tax increases, or relocation for work may have various impacts on a borrower's situation but do not directly lead to default in the way that unresolved title issues can.
