Abstract: According to certain embodiments, a user device comprises a communication interface, an input/output (I/O) interface, and processing circuitry. The processing circuitry is configured to obtain a maximum pre-approval amount, generate a graphical user interface comprising an adjustable pre-approval field that enables a user to select up to the maximum pre-approval amount to include in a pre-approval letter, display the graphical user interface via the I/O interface, and receive an input associated with the adjustable pre-approval field via the I/O interface. The input indicates an adjusted pre-approval amount selected by the user. The processing circuitry is further configured to facilitate generating the pre-approval letter indicating that a customer has been pre-approved for the adjusted pre-approval amount, the pre-approval letter including a pre-authorized signature of a lender and generated without sending the lender the adjusted pre-approval amount.
