Washington Mortgage Statutory Form is a set of legally-binding documents required for any mortgage loan in the state of Washington. These forms include the loan application, disclosure statements, promissory note, and security instrument. There are two types of Washington Mortgage Statutory Forms: the Standard Form, which is used for most residential loans, and the Alternative Form, which is used for commercial loans or when special circumstances exist. The Standard Form provides basic information about the loan, including the loan amount, interest rate, term, and loan-to-value ratio. It also includes information about the mortgagee, such as the name and address, and the mortgagor, such as the name, address, and Social Security number. The Alternative Form includes additional information and is more complex than the Standard Form. It includes more detailed information about the loan, including additional loan-to-value ratios, and is typically used when special circumstances exist or when a commercial loan is involved.
