What is the mortgage payment due date for the seller's existing loan if it closes on October 2 and the last payment was made on September 9?

The correct answer is October 1. When a mortgage loan is in effect, payments are typically made on a scheduled basis, often monthly. In this context, if the last payment was made on September 9, it means that the next payment due would occur on the first day of October.

Payments are commonly based on a monthly cycle, and the fact that the closing occurs on October 2 does not impact the timing of the existing mortgage payment due date. Therefore, the seller would have owed a mortgage payment on October 1, regardless of the closing date, because the payment period runs from one due date to the next.

If a mortgage payment is due on the first of the month, then the next expected payment wouldn't be due until November 1. Thus, any date after October 1 would be incorrect, as it does not align with the established payment schedule for their current mortgage.
