Can't get all the receipts to meet 30 days to refund the deposit

[Andy Wu]

1. If I can't get all the repair receipts in 30 days after tenant moving out. What should I do?

2. I paid the tenant to move out 10 days earlier (prorated), so I can have new tenant move in. However, the house was so dirty and has bedbugs. New tenant refuse to move in.  Can I get the refund rent back as the house is uninhabitable for bedbug issue.
