Which of the following is a requirement for all high-cost mortgage transactions?

Clear disclosures being provided to the borrower is a fundamental requirement for all high-cost mortgage transactions. This requirement aligns with the intent of the Home Ownership and Equity Protection Act (HOEPA) which aims to protect consumers from predatory lending practices. The law mandates that lenders give borrowers essential information about the terms and costs of the loan, ensuring that borrowers can make informed decisions.

These disclosures help borrowers understand their obligations and any potential financial risks associated with their high-cost mortgages. Key disclosures typically include the loan's annual percentage rate (APR), total points and fees, and other significant terms that could impact a borrower's financial situation.

In contrast, the other options involve conditions that are either not universally applicable to high-cost mortgages or are factors that may not align with compliance requirements. For instance, a loan-to-value ratio exceeding 100% is not a standard requirement and can lead to risky lending practices. Prepayment penalties cannot be enforced in many scenarios under high-cost mortgage regulations due to consumer protection laws. Similarly, while adjustable interest rates can be involved in certain types of mortgages, they are not a requirement for high-cost mortgages.
