A blanket mortgage is also known as a wrap-around mortgage, a single mortgage, or a blanket loan. These terms are used to describe a mortgage that covers multiple properties or lots. The loan is secured by the borrower's total equity in those properties. Blanket mortgages are often used by real estate investors and developers who buy several properties at once. By using a blanket mortgage, they can consolidate all their debt into a single loan with one lender and one payment. Other synonyms for blanket mortgage include portfolio mortgage, cross-collateralization, and all-inclusive trust deed. Regardless of the term used, they all refer to the same type of loan.
