Which option does NOT contain one of the six pieces of information required to officially begin a loan application?

The correct choice highlights that the listed option does not encompass one of the six critical pieces of information necessary to officially commence a loan application. When starting a loan application, lenders typically require specific details that include the borrower's name, income, social security number, date of birth, the address of the property for which the loan is being sought, and the loan amount.

In this context, while the borrower's social security number and date of birth are important for identity verification and credit history checks, they are not part of the initial six pieces of information required to officially begin the application process. The focus at this stage is more on specific financial and property-related data that establishes the key framework for the loan.

Other options, such as the borrower's name and income, the address of the property, and the amount of the loan, directly pertain to the essential elements needed to start the application process, including determining eligibility and understanding the borrower's financial situation. The estimated value of the property is also crucial, as it helps in assessing the loan amount in relation to the property's worth when evaluating risk.
