Which of the following is NOT a power of the Commissioners in administering mortgage-related laws?

Determining license fees is not typically within the power of the Commissioners in administering mortgage-related laws. The role of the Commissioner generally includes the enforcement and regulation of mortgage lending practices, which involves issuing cease-and-desist orders to halt unlawful activities, revoking licenses of those who violate laws or regulations, and conducting investigations into mortgage practices and complaints.

The determination of license fees, on the other hand, often falls under legislative authority or specific administrative rules set by a governing body rather than by the Commissioner themselves. This separation helps ensure that fees are set in a manner that reflects broader legislative intent, considering the needs of the industry and public. Therefore, the correct answer highlights a function that is outside the typical scope of the Commissioner's powers, focusing instead on the enforcement and regulation aspects of their role.
