We will see if true but he's requested an invoice for damages caused and back rent.

Small fixes will not do a dang thing, I'm afraid.

If you don’t, it can be pretty dang stressful. 

Try to have the contractors provide you an updated invoice indicating paid in full/ work completed.  

Invoice them for damages, legal fees and get the property for the next tenant.

@Kevin Dang i just want to see if the a meet up meeting I can attend to.

If so, I wonder if I should just send an invoice to the tenants each month for their water usage and cable bill.

If you can, try to get contractor invoices paid.

Meanwhile, the day I filed the dispo, the tenant called to tell me the AC stopped working, I sent an AC company out, who had to go out multiple times and thought something seemed fishy, the $380 invoice had a note that during one service call a guy (who was not the tenant) climbed through a window to let the AC guy in.

Although I have already read about the laws related to security deposit matter in CA Civil Code Section 1950.5, I would like the property owners with similar experiences to me consider my situation and advise me regarding the following items1- How to calculate their security deposit and provide an itemized list, while I do not have any invoice in my hands. 2- As my tenants have not left any forwarding address, shall I contact and ask her the new address for sending the itemized list?
