The essence of Collateral Risk Measure (CRM) is that it helps everyone understand the potential downside of real estate investment. Lenders use this type of tool on nearly every loan in their portfolio because they want to understand their exposure if the loan goes bad. That is, they want to know how much money they will lose if the property goes into foreclosure. So, they review area foreclosure activity, property flipping events, appreciation/depreciation trends, property history and other factors that can influence the value of a property and that gives them insight as to their risk potential.
