Multifamily LoanDynamics (LDM) is our loan-level model designed to help multifamily investors, servicers, issuers, and lenders evaluate and quantify the prepayment and credit risk of their multifamily mortgage assets. The model forecasts a monthly vector of prepayment speeds that can be separated into voluntary and involuntary components. These vectors can be used in cash flow projections, bond pricing and valuation, asset and liability management, and hedging.
