Streamline Ucc Insurance Flood and Tax
This mainly tracks Insurance, Tax, UCC (Uniform Commercial Code) and Flood information for Commercial Real Estate Loans using Risk Management Department (RMD) of the Real Estate and Capital Markets Groups. RMD primarily supports the Real Estate Group (REG) and the Capital Market Group (CM). The loans generated from the REG are usually boarded on the AFS loan accounting system. The loans in the CM group are split between the Strategy loan accounting system and AFS, depending on the business. Within CM, most of the loans are boarded on Strategy. Each group sells a different loan product and has different credit rules based on that product, so RMD has established their processes to accommodate the different groups. Because of this, the use cases and overall requirements will note the different processes.
