US Patent 11010830 Loan selection interface for a vehicle transfer transaction

A vehicle transfer system provides a transaction interface that is displayed as part of a web page for a vehicle on a vehicle dealer's website. The transaction interface allows a customer to perform a vehicle transfer transaction on the dealer's website. The system can facilitate multiple financing methods for the transaction. If the transaction is financed with a loan, the system can request loan offers for a plurality of different loan terms and down payment amounts, and then provide a loan selection interface, which allows the customer to select a loan term and down payment amount and then displays the loan offers matching the customer's selections. If the transaction is financed with a lease, the system can perform a leasing calculation that solves for a balancing point between the total upfront capital that is available to the customer and the total expenses due at lease signing.
