1. Maryland Code, Real Property, § 7-105.1. This section outlines the required procedures for a lender to initiate a power of sale or foreclosure, which is predicated on a borrower's default on a mortgage or deed of trust. The statute's existence and content confirm that foreclosure is a legal process for selling property to satisfy a debt.
2. University of Maryland Extension. In publication FS-967, "Homeowners: Facing Foreclosure?", foreclosure is defined as "a legal process that allows your lender to sell your house because you have not made your mortgage payments." This directly supports the concept of a forced sale due to default.
3. Consumer Financial Protection Bureau (CFPB). In its "Mortgage and housing assistance glossary," the CFPB, a U.S. government agency, defines foreclosure as a process that "happens when a homeowner fails to pay the mortgage... If the homeowner cannot pay off the outstanding debt, or sell the property via short sale, the property then goes to a foreclosure auction." This confirms the cause is default and the result is a forced sale.
