5 steps to a demand letter that gets a response

  1. 1

    State the facts up front

    Open with your deposit amount, the property address, and your move-out date. Make clear you are formally disputing the deductions — not asking a favor.

  2. 2

    Cite N.M. Stat. § 47-8-18

    Reference New Mexico Statutes § 47-8-18 by name. New Mexico landlords must return the deposit within 30 days and may only withhold for damage beyond normal wear and tear. Naming the statute signals you know your rights.

  3. 3

    Itemize every disputed charge

    List each deduction and explain why it is not lawful — routine cleaning, repainting, and ordinary carpet wear are the landlord's cost of doing business, not yours.

  4. 4

    State the penalty exposure

    Spell out that wrongful withholding under N.M. Stat. § 47-8-18 can expose the landlord to damages up to 2× the wrongfully withheld amount plus attorney's fees. This is what moves landlords to settle.

  5. 5

    Set a deadline and send certified

    Demand return within 30 days and send the letter via USPS Certified Mail with Return Receipt. The receipt is your proof of delivery if you end up in New Mexico small claims court (limit $10,000).
