Addendum to Purchase Agreement (Universal) — Massachusetts 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 Massachusetts Edition: the template and its drafting notes are adapted for Massachusetts practice under M.G.L. c. 112, §§ 87PP–87DDD½ and the Board of Registration of Real Estate Brokers and Salespersons regulations at 254 CMR, including the Mandatory Licensee-Consumer Relationship Disclosure under 254 CMR 3.00. Massachusetts permits dual agency and designated agency only with informed written consent, so the consent document in this edition offers both elections. Massachusetts is a caveat emptor state with no statutory seller property-condition form; this edition's Seller Property Condition Disclosure is therefore drafted as a voluntary disclosure that reduces M.G.L. c. 93A exposure and is designed to sit alongside the Commonwealth's Property Transfer Lead Paint Notification, Title 5 septic inspection report, and smoke/CO detector certificate. The Independent Contractor Agreement is built around M.G.L. c. 112, § 87RR, which expressly permits salesperson affiliation as an independent contractor notwithstanding the c. 149, § 148B ABC test. Electronic signatures are addressed under the Massachusetts Uniform Electronic Transactions Act, M.G.L. c. 110G. Not legal advice; have a Massachusetts-licensed attorney review before use.
