Method and apparatus for determining loan prepayment scores
First Claim
1. A system for determining prepayment scores representative of prepayment propensity of consumers for consumer mortgage loan originations, comprising:
- a plurality of loan origination terminals for accepting and transmitting consumer mortgage loan applications;
a network connected to the plurality of loan origination terminals for receiving the transmitted consumer mortgage loan applications;
a communication server connected to the network for receiving the transmitted consumer mortgage loan applications;
an application parser connected to the communications server for receiving the transmitted consumer mortgage loan applications from the communications server and parsing the information into loan information and applicant information;
a prepayment model library database comprising loan prepayment models connected to the application parser for receiving the loan information and fitting the loan information into the loan prepayment models and for transmitting loan prepayment models that match the loan information; and
a prepayment calculation server comprising a prepayment score generation model connected to the prepayment model library database for receiving the loan prepayment models and calculating prepayment scores for each consumer mortgage loan application based upon the loan prepayment model and the prepayment score generation model, the prepayment calculation server is further adapted to transmit the prepayment scores to any one of the plurality of loan origination terminals via the communications server and the network;
where the prepayment score is calculated from the formula;
where T represents time and P represents prepayment; and
wherein the plurality of loan origination terminals are adapted to use the prepayment scores to adjust terms of the consumer mortgage loans.

Abstract
A method and apparatus for determining the prepayment propensity of borrowers. Earlier payment of loans and particularly mortgage loans can lead to losses being suffered by lenders. The present invention analyzes the demographics associated with a particular borrower to determine both the individual and group based prepayment propensity. The history of the borrower, the history of the demographic group to which the borrower belongs, interest rate trends and other factors are then used to calculate a prepayment score that can be used by the lender to determine the propensity of a given borrower to prepay the loan in question. Where prepayment is a significant risk, inducements to the borrower to leave the loan in force can be made or the loan product can be adjusted to reflect the prepayment risk involved. Loan brokers can also be rated based upon the prepayment propensity of those borrowers who are clients of the broker. As with borrowers, a prepayment score can be attributed to a loan broker based upon the prepayment behavior of the brokers clients. This will help lenders assess the success of brokers with whom the lender deals.
