The cap is 1 month's rent. The return deadline is 30 days after termination of the rental agreement / surrender of possession, with an itemized list of deductions. Interest: Yes on deposits exceeding one month’s rent on leases of one year or more — interest must be paid; otherwise interest is not generally required. That is what separates New Mexico getting a security deposit back from a generic national summary. Read N.M. Stat. Ann. § 47-8-18 before the background sections below. Wrongful withholding can support damages of twice the amount wrongfully withheld plus attorney fees under the Uniform Owner-Resident Relations Act.

A concrete New Mexico scenario
Here is one way the New Mexico pieces fit together. Change any fact and the statute may point somewhere else.
A residential tenant moves out of a New Mexico rental and the landlord has not returned the deposit.
- Check the cap that applied when the deposit was collected: 1 month's rent.
- Calendar the return deadline: 30 days after termination of the rental agreement / surrender of possession, with an itemized list of deductions
- Interest, if any: Yes on deposits exceeding one month’s rent on leases of one year or more — interest must be paid; otherwise interest is not generally required.
- If the landlord keeps money without the required accounting: Wrongful withholding can support damages of twice the amount wrongfully withheld plus attorney fees under the Uniform Owner-Resident Relations Act.
New Mexico caps most deposits at one month’s rent and requires return with itemization within 30 days. Interest may apply on larger deposits for longer leases. Magistrate or metropolitan court handles many disputes.
