Addendum to Purchase Agreement (Universal) — New Mexico Edition Template

Deals change after signing — repair credits get negotiated after inspection, closing dates slip, appraisal gaps get bridged, personal property gets added or removed. The clean, enforceable way to document any of it is a written addendum executed by all parties, because nearly every purchase agreement contains an integration/merger clause providing that modifications must be in writing, and the statute of frauds in every state requires material modifications to real estate contracts to be written anyway.

This Universal Addendum to Purchase Agreement is deliberately flexible: it identifies the underlying contract by parties, property, and effective date; provides numbered blank provisions for the new or modified terms; states that all other terms of the purchase agreement remain in full force and effect; handles conflicts between the addendum and the original agreement (addendum controls); and includes execution blocks for all buyers and sellers with dates. It is the form you reach for dozens of times a year.

The 3-page template also ships with a drafting guide containing ready-to-adapt clause language for the most common addendum scenarios: inspection repair resolutions, closing date extensions, appraisal gap provisions, seller concessions and credits (with a note on lender concession caps), personal property inclusions, post-closing occupancy stubs, and contingency waivers. The 50-state notes flag jurisdictions with specific counterpart-execution or electronic signature nuances (all states have adopted UETA or equivalent, and federal E-SIGN, 15 U.S.C. § 7001, validates electronic signatures, but practice details vary). Template for drafting purposes — review significant modifications with a broker or attorney.

About this New Mexico Edition: New Mexico licenses only associate brokers and qualifying brokers, so every form names the brokerage (acting through its qualifying broker) as the contracting party and routes all compensation through the qualifying broker, consistent with the Real Estate License Law (NMSA 1978 § 61-29-1 et seq.) and the NMREC rules at 16.61 NMAC. The brokerage-relationship forms are built around 16.61.19 NMAC: transaction broker is the default, seller/buyer agency arises only by written agreement after a written Broker Duties disclosure, and dual agency requires prior written consent of both parties — hence the "Dual Agency Disclosure & Consent" title and the removal of the master template's designated-agency alternative. Because New Mexico has no statutory seller-disclosure form, the condition disclosure is drafted as a voluntary actual-knowledge statement anchored to the broker's 16.61.19 NMAC duty to disclose adverse material facts, with New Mexico-specific sections on wells, septic, acequia/water rights, flat roofs, and HOA/tax-levy attachments. Electronic execution cites the New Mexico UETA (NMSA 1978 § 14-16-1 et seq.); the statute of frauds, broker-lien absence, and community-property spousal signatures are phrased generally.
