Which of the following acts does NOT pertain to the regulation of mortgage lending?

The Grant Loan Act is not directly related to the regulation of mortgage lending in the same way the other options are. The Real Estate Settlement Procedures Act (RESPA) focuses on the transparency of settlement costs related to the buying of a home, while the Truth in Lending Act (TILA) ensures that consumers are informed about the costs of borrowing, allowing them to compare different loan offers easily. The Equal Credit Opportunity Act (ECOA) prohibits discrimination in lending, ensuring that all consumers have fair access to credit. In contrast, the Grant Loan Act does not specifically regulate mortgage lending practices or consumer protections in the same comprehensive manner as the other acts mentioned.
