Short answer: New Mexico security deposit law limits the deposit to one month’s rent for rental agreements shorter than one year, and requires interest on larger deposits under annual agreements, under NMSA 1978 § 47-8-18(A). The owner must send an itemized list of deductions and any balance within thirty days after the rental agreement ends or you leave, whichever is later, under § 47-8-18(C). An owner who misses that deadline forfeits the right to keep any of the deposit and owes your court costs and reasonable attorney’s fees, and bad-faith retention adds a $250 civil penalty under § 47-8-18(D) and (E).
The forfeiture rule is what gives New Mexico security deposit law its teeth. A landlord who misses the 30-day statement doesn’t just lose the right to deduct. Under § 47-8-18(D), the landlord also loses the right to counterclaim when you sue for the deposit, and even the right to file a separate lawsuit against you for damage to the unit. Few states go that far.
The statute text quoted here comes from the Uniform Owner-Resident Relations Act as published by the New Mexico Real Estate Commission, part of the state’s Regulation and Licensing Department. Its history note shows § 47-8-18 was last amended in 1989.

How much a New Mexico owner can collect
Section 47-8-18(A) lets an owner demand “a reasonable deposit” to cover damage the resident causes. How much is allowed depends on the length of your agreement.
- Agreement shorter than one year (including month-to-month): the owner “shall not demand or receive” a deposit greater than one month’s rent, under § 47-8-18(A)(2).
- Annual agreement: there is no fixed cap, but if the deposit exceeds one month’s rent, the owner must pay you interest every year, under § 47-8-18(A)(1).
The interest rate is tied to “the passbook interest permitted to savings and loan associations in this state by the federal home loan bank board.” The statute gives no number, so ask your landlord in writing what rate it uses. The statute does not require a separate bank account or a disclosure of where the money is held.
Last month’s rent is separate
Under § 47-8-18(B), the deposit rules are not meant to include “the last month’s prepaid rent, which may be required by the rental agreement.” The two are kept apart in both directions: a damage deposit “shall not be construed as prepaid rent.” A landlord may require last month’s rent on top of a one-month deposit. And you can’t treat your damage deposit as your final month’s rent.
Deductions and normal wear and tear
When the residency ends, § 47-8-18(C) allows the owner to apply the deposit to unpaid rent and to damages caused by your noncompliance with the rental agreement or with § 47-8-22, the statute listing a resident’s obligations. It also states plainly: “No deposit shall be retained to cover normal wear and tear.” The owner may keep money for “nonpayment of rent or utilities, repair work or other legitimate damages.”
New Mexico doesn’t require a move-in checklist in the deposit section. A dated set of photos and a written list of existing problems, emailed to the owner in your first week, fill that gap. Our wear and tear guide shows what typically falls on each side of the line.
The 30-day statement
If the owner keeps anything, § 47-8-18(C) requires “an itemized written list of the deductions from the deposit and the balance of the deposit, if any, within thirty days of the date of termination of the rental agreement or resident departure, whichever is later.” The “whichever is later” language helps landlords if you leave before your lease ends: the clock may not start until the agreement terminates.
The owner is “deemed to have complied” by mailing the statement and payment to your last known address. Give your forwarding address in writing on move-out day so the mailing reaches you. Our deadline checker will count the days.
What happens when the owner misses the deadline
Section 47-8-18(D) lists four consequences when the owner fails to provide the written statement and balance within thirty days. The owner:
- “shall forfeit the right to withhold any portion of the deposit”;
- “shall forfeit the right to assert any counterclaim in any action brought to recover that deposit”;
- “shall be liable to the resident for court costs and reasonable attorneys’ fees”; and
- “shall forfeit the right to assert an independent action against the resident for damages to the rental property.”
On top of that, § 47-8-18(E) makes an owner “who in bad faith retains a deposit” liable for a $250 civil penalty payable to you. Unlike states with double or triple damages, New Mexico’s money penalty is a flat amount, but the loss of every damage claim can be worth far more to a landlord than the deposit itself.

Worked example
Luis signs a one-year lease in Albuquerque at $1,100 a month and pays a $1,650 deposit. Because that’s more than one month’s rent under an annual agreement, his landlord owes him interest each year under § 47-8-18(A)(1). His lease ends June 30; he moves out that day and emails his new address.
- The thirty-day deadline is July 30. No statement or refund arrives.
- Luis files for return of the deposit. Under § 47-8-18(D), the landlord has forfeited the right to withhold anything, can’t counterclaim for the scuffed floor he complains about, and can’t sue Luis separately for it.
- Recovery: the full $1,650 plus any unpaid annual interest, plus court costs and reasonable attorney’s fees.
- If the court finds the landlord kept the money in bad faith, add $250 under § 47-8-18(E), for $1,900 before costs and fees.
A written demand that quotes subsection D often ends the dispute; our demand letter guide has a template.
Filing in magistrate court
According to the New Mexico Courts’ guide to filing a civil lawsuit, magistrate court “CANNOT consider any case where the amount of money claimed by a party is more than $10,000.” You can file in the county where you live, where the landlord lives, or where the events happened. The state judiciary also lists a “Complaint by resident for return of deposit” (form 4-906A) among its landlord-tenant forms, according to the Supreme Court Law Library’s resource guide.
A deposit claim can also be raised as a counterclaim if your landlord files an eviction case against you, as the Third Judicial District’s landlord-tenant brochure notes. See our small claims guide for preparation.
Sale of the building and other situations
New owner. Under § 47-8-21(A), when an owner’s interest ends by sale, assignment, death, bankruptcy or otherwise, the old owner is relieved of obligations for events after written notice to you, and “the successor in interest to the owner shall be liable for all obligations” under the rental agreement and the Act. That includes returning your deposit.
Death of a resident. Section 47-8-34.2 lets an owner ask you to name a contact person and authorize the owner to refund your deposit, less lawful deductions, to that person if you die while living alone in the unit.
Exempt arrangements. Section 47-8-9 excludes, among others, transient hotel or motel stays, institutional residence, occupancy under a contract to buy, and employee housing conditioned on employment.
Frequently Asked Questions
Is there a deposit cap on a one-year lease in New Mexico?
No fixed cap, but the deposit must be “reasonable,” and if it exceeds one month’s rent the owner must pay you annual interest under § 47-8-18(A)(1). The one-month cap applies to agreements shorter than one year.
Can my landlord charge first month, last month and a deposit?
Yes. Section 47-8-18(B) separates last month’s prepaid rent from the damage deposit, so collecting both is allowed, subject to the deposit limits.
Can my Santa Fe landlord sue me for damage after missing the 30-day deadline?
No. Under § 47-8-18(D)(4), an owner who fails to send the statement on time forfeits the right to bring an independent action against you for damage to the rental property.
How large is the bad-faith penalty?
A flat $250 civil penalty payable to you, under § 47-8-18(E), in addition to the deposit, costs and attorney’s fees.
