Which of the following is an essential requirement for a Mortgage Call Report?

The essential requirement for a Mortgage Call Report is data on mortgage lending activity for regulatory monitoring. This report serves as a vital tool for regulators to oversee lending practices and identify trends within the mortgage industry. By compiling this data, regulatory bodies can ensure compliance with relevant laws, assess the financial health of mortgage lenders, and help maintain the stability of the housing market.

Other options, while they may contain relevant information for a lender's broader reporting practices or internal assessments, do not align with the core purpose of the Mortgage Call Report. Details on each borrower's income or a list of all loan denials may be useful for internal tracking and assessment but are not fundamental to the regulatory monitoring process outlined in the Mortgage Call Report. Similarly, insurance details covering properties financed may be important for the lender's operations but fall outside the remit of what is required in the specific context of this report. Thus, the primary focus remains on the overall activity data that supports regulatory oversight.
