New Mexico Security Deposit Law Explained
If you moved out of a New Mexico rental, you are usually looking for three things: your deposit balance, a real written explanation for any deductions, and proof that the landlord handled the deadline correctly.
The practical rule
New Mexico generally requires the landlord to provide the resident with an itemized written list of deductions and any deposit balance within 30 days after termination of the rental agreement or resident departure, whichever is later.
No deposit may be retained for normal wear and tear. If the landlord keeps money, the written statement should give the exact reasons for withholding.
Watch these proof points
Keep proof of move-out, surrender, your forwarding address, the lease term, and the deposit amount. The 30-day deadline, mailing record, and cap/interest rule all depend on those basic facts.
Deposit cap and interest
For a rental agreement shorter than one year, New Mexico generally does not allow the landlord to demand or receive a deposit in excess of one month's rent.
For an annual rental agreement, a landlord may take more than one month's rent as a deposit, but the landlord must pay annual interest on the amount above one month's rent at the required passbook-interest rate described in the statute.
What the landlord can deduct
New Mexico supports deductions for unpaid rent, late fees, utilities, repairs, cleaning, and other legitimate damages or charges. The landlord still needs actual cause and a written itemized list.
Normal wear and tear is off limits. That is why photos, move-in records, cleaning records, and repair history matter.
If the landlord misses the rule
If the landlord fails to provide the written statement of deductions and payment required within the 30-day period, New Mexico law can forfeit the landlord's right to withhold any portion of the deposit. It can also affect the landlord's ability to bring counterclaims or separate claims for those charges.
New Mexico also provides a civil penalty equal to twice the amount improperly withheld. That is a strong reason to get the timeline, itemization, and amount owed clear before escalating.
