Paying HAP for Late Move-Out

Q If a resident gives a 30-day notice to move out at the end of the month, but does not actually move out until the middle of the following month, is the owner entitled to that month's housing assistance payment (HAP)? The resident's new unit was inspected and approved, and the new owner was issued the HAP on the first of the month, but the resident did not move in until the middle of the month.
