Which document provides the total interest paid over the life of the loan?

The Closing Disclosure is the correct answer because it is specifically designed to provide borrowers with a clear summary of the key loan terms and the total costs involved in acquiring the mortgage. This document includes important financial information, such as the loan amount, interest rate, monthly payment, and crucially, the total interest paid over the life of the loan. This feature is essential for borrowers to understand how much they will ultimately pay over the duration of the loan.

The Loan Estimate serves a different purpose by summarizing the estimated costs at the beginning of the loan process, but it does not give the final figures, which are detailed in the Closing Disclosure. The Loan Application is primarily focused on gathering the necessary information about the borrower, and the Borrower's Agreement outlines specific terms agreed upon by the borrower but does not provide a total of interest over the loan's lifespan. Therefore, the Closing Disclosure is the key document that summarizes overall costs and is crucial for making informed financial decisions.
