When moving out of an apartment, we all want to get our security deposit back. But what can be deducted? Knowing this can get us more of the money back that we paid up front. The Texas Apartment Association gives this explanation.

Any charge specified in the lease or any charge resulting from your breaking the lease.
Charges for damages, wear and tear resulting from negligence, carelessness, accident or abuse on your part. “Normal wear and tear” items cannot be deducted.
Unpaid rent and other unpaid charges listed in your lease, such as those for late rent payment, returned checks, missing furniture or fixtures, keys you don’t return to the management, etc.
The reasonable cost of cleaning if you fail to properly clean before you leave. Many rental properties have written cleaning instructions for you to follow.

Any deduction must be listed in a written description and itemization mailed to you on or before 30 days after you leave. However, there is no obligation that you be furnished this information if you have not paid all of your rent or if you have not given your forwarding address in writing.
