Addendum to Purchase Agreement (Universal) — Iowa 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 Iowa Edition: Every template was redrafted around Iowa's real estate license law, Iowa Code chapter 543B, and the Iowa Real Estate Commission's rules in 193E IAC, which require written brokerage agreements with definite expiration dates, a written agency disclosure before any brokerage agreement or offer, and the informed written consent of all parties before a brokerage may act as a dual agent or through appointed (designated) agency — so the consent form in this set is a true Iowa dual agency / appointed agency election rather than a transaction-brokerage substitute. The seller disclosure form is structured to Iowa Code chapter 558A (delivery before the buyer's written offer) and adds the Iowa-specific items practitioners expect: radon, the time-of-transfer septic inspection under Iowa Code chapter 455B, and the groundwater hazard statement categories. Throughout, the forms reference the Iowa statute of frauds (Iowa Code § 622.32), the Iowa Uniform Electronic Transactions Act (Iowa Code chapter 554D), homestead spousal joinder (Iowa Code § 561.13), the commercial broker lien act (Iowa Code chapter 570A), Iowa's abstract-and-Title-Guaranty title practice, and the rule that all compensation flows through the licensed brokerage.
