2.3 Property Disclosure Requirements

New Mexico's residential property-disclosure regime sits at the intersection of state statute, NMREC practice, and federal law. The headline state authority is the Real Estate Disclosure Act (NMSA 1978, Sections 47-13-1 et seq.), which most notably exempts so-called "stigma" facts from disclosure. Layered on top are NMREC's practice expectations (a standardized Seller's Property Disclosure and a unique property-tax estimate) and federal lead-based-paint rules. Understanding what must be disclosed, what is exempt, and what is federally required is essential for the state portion.

The Seller's Property Disclosure

For residential resales, the seller completes a Seller's Property Disclosure describing the property's condition and any material defects of which the seller has actual knowledge. A material defect is one that would affect a reasonable buyer's decision or the property's value or desirability.

The standard is actual knowledge — New Mexico does not impose a duty to inspect or to discover hidden defects, but a known defect cannot be concealed.

New Mexico's Unique Property-Tax Estimate

This is one of the most heavily tested, genuinely New Mexico-specific rules. Before accepting a buyer's offer, the seller (or the seller's broker) must:

1. Request an estimate of the annual property-tax levy from the county assessor, using the listed/selling price as the value basis;
2. Obtain the assessor's written response; and
3. Deliver that written estimate to the buyer (or the buyer's broker) before the offer is accepted.

The reason behind the rule is New Mexico's tax structure: because of valuation caps and "tax lightning," a property's taxes can jump sharply when it sells, since the assessed value resets toward the sale price. The mandatory estimate warns buyers that their taxes may be much higher than the prior owner paid.

Exam framing: If a question asks what New Mexico uniquely requires before a seller accepts an offer, the answer is the county-assessor property-tax estimate based on the listed price — not a generic "tax disclosure."

Putting the Disclosure Rules to Work

The exam rarely asks you to recite a statute; it asks you to sort facts into "must disclose," "exempt," or "federal." Use this triage.

The Tax Estimate, Step by Step

Because the property-tax estimate is so distinctively New Mexico, expect a question built around its timing and mechanics: the seller or seller's broker requests the estimate from the county assessor, using the listed price as the value, and delivers the assessor's written response to the buyer before the seller accepts the offer. Miss any element — wrong source (not a private estimate), wrong value basis (must be listed price), or wrong timing (must be before acceptance) — and the answer is wrong.

Amendment and Liability, Reinforced

The disclosure is a living document until closing: a defect discovered during inspections must be added. A seller (or complicit broker) who conceals a known material defect risks fraud, negligent-misrepresentation, and breach claims, plus, for the broker, NMREC discipline. The throughline is consistent with Chapter 2's agency rules: known material physical facts must surface; protected-class and stigma facts must not.

Federal Lead-Based-Paint Disclosure

For target housing built before 1978, the federal Residential Lead-Based Paint Hazard Reduction Act (Title X) applies regardless of state law:

This federal duty stacks on top of New Mexico's seller disclosure for any pre-1978 home.

What New Mexico Does NOT Require: "Stigma" Facts

The Real Estate Disclosure Act (Section 47-13-2 NMSA 1978) provides that no cause of action arises against an owner or broker for failing to disclose that the property was the site of:

These exemptions protect against "psychologically impacted property" claims. Note the boundary: a physical defect linked to an event (for example, fire damage from a crime, or methamphetamine contamination affecting habitability) is a material fact and must be disclosed — the exemption covers the stigma, not the physical condition.

Ongoing Duty to Amend, and the Cost of Concealment

The seller's disclosure is not a one-time snapshot. If the seller learns new information that should be disclosed between signing the disclosure and the close of sale, the seller must amend the form. A defect that becomes known during the inspection or contingency period, for instance, triggers an update.

Consequences of Nondisclosure or Concealment

A seller who conceals a known material defect, or a broker who knowingly participates, can face civil liability:

Synthesis: New Mexico's scheme is "known material physical facts in; protected-class and stigma facts out." Disclose what the seller actually knows about condition, deliver the tax estimate and (for pre-1978 homes) the lead packet, amend when new facts surface, and never disclose protected-class or exempt stigma information.
