What must lenders disclose if the interest rate is subject to increase before the expiration of the commitment?

• A. The terms of the loan repayment schedule
• B. The type of loan being issued
• C. The basis, index or method used to determine the rate at closing
• D. The creditworthiness of the borrower

Answer: (C)

The correct choice emphasizes the importance of transparency regarding how the interest rate is determined, particularly when there is potential for an increase prior to the loan commitment's expiration. Lenders are required to disclose the basis, index, or method used to determine the interest rate at closing. This requirement helps borrowers understand how their interest rate could fluctuate and what factors may cause changes, thus allowing them to make informed decisions regarding their mortgage agreement.

By providing this information, lenders uphold the principles of fair lending and transparency, ensuring borrowers are aware of potential costs and risks associated with their loan. This clarity is crucial because it allows borrowers to gauge the loan's volatility and manage their financial planning accordingly.

Understanding the index or basis of the rate is essential for borrowers to anticipate how future interest rate changes may impact their monthly payments and overall loan affordability.
