A computer-implemented cash flow decomposition and repackaging system comprises processing logic and a graphical user interface which is coupled to the processing logic. The processing logic decomposes each of a plurality of home mortgage loans into a plurality of sub-loan level cash flows and repackages the plurality of sub-loan level cash flows to form a plurality of financial assets backed by the plurality of sub-loan level cash flows in accordance with operator inputs. The user interface displays indicia representative of the sub-loan level cash flows, the financial assets, and a relationship between the plurality of sub-loan level cash flows and the plurality of financial assets, including a manner in which at least some cash flows are traceable back to one or more of the plurality of home mortgage loans.
