When my renters left my house, the cost to repair/replace damaged items would have exceeded the amount of their security deposit. I sold the house immediately after they moved out. I learned that I have to provide them with receipts for cost of repairs. However, since I sold the house, the cost was in the loss of value of the house, not in repairs for which I have receipts. Although I have evidence of the damage which would clearly show loss of value to the house exceeded their deposit amount at least three times over, do I still have to refund anything for which I don't have a receipt.

Get estimates for repairs from three contractors.

Any question on law needs to include your general locale as laws vary by area.

However, most areas require that the landlord return the deposit or an itemized accounting of how it was used, within a specified time. Usually, if the landlord does not return the deposit or provide such an accounting within the time frame they forfeit the right to keep the deposit. So it may be too late for you. If the tenants sue, you will probably lose because you did not follow the law.
