Definition: "Remortgaged" is a legal term that refers to the process of converting a mortgage from one type of loan (such as a first-time home purchase or commercial real estate loan) into another type of loan, such as a refinancing or a second mortgage. This involves paying off the original mortgage and replacing it with a new loan on the same property. Remortgaged mortgages are often used by homeowners who want to reduce their monthly payments or avoid early payment penalties.
