Addendum to Purchase Agreement (Universal) — New Hampshire 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 Hampshire Edition: Every form names the brokerage firm, acting through its principal broker, as the contracting party and acknowledges delivery of New Hampshire's mandatory brokerage relationship disclosure, consistent with RSA Chapter 331-A and the New Hampshire Real Estate Commission's rules. New Hampshire permits disclosed dual agency with written informed consent and also authorizes designated agency, so the consent document covers both regimes. New Hampshire has no comprehensive property condition disclosure statute; the seller disclosure is built first around the statutory pre-contract disclosures (water supply, sewage disposal, insulation, and the radon, arsenic, and lead notices under RSA 477) and then adds a clearly labeled voluntary general-condition section. Closing-related forms are drafted around attorney and title-company closing practice. Electronic signatures are addressed under New Hampshire's Uniform Electronic Transactions Act. No association forms are reproduced.
