Whenever data is received from an outside source, it is imperative that it can instantly be processed and verified.
For example, is there a state column for the property address? Does it have a value? Is it a valid two-character postal
code? Is it consistent with the provided zip code? If the loan has an adjustable rate, is a margin provided? These questions
pile up across dozens if not hundreds of columns. They can vary based on the company, the product, the data source and many other factors.
CAS makes it easy to create, manage, maintain and execute these questions on your data the moment you receive it. For each loan, you will
know exactly which data problems or exceptions it has, and which data items contribute to those problems. And for each exception you will
know exactly which loans have that particular problem.
Results of this analysis can be reported and used internally in CAS, or automatically exported into richly formatted spreadsheets for other users, clients or business partners.
In addition to basic data integrity, the same facility is used to test loans for program eligibility. For example, a loan program may require the LTV to be below a certain value, and only owner-occupied properties, and so on.
