Your Seller-Drafted Commercial Contract Might Leave Openings You Don’t Expect

Commercial real estate sellers often believe they can gain more control over a transaction by writing their own contracts. That may make sense on the surface, but it often leads to issues someone experienced in Arizona commercial real estate could have warned you about.

As much as you might think your customized contract fits your situation perfectly, the buyer's attorney will likely find gaps. Standard forms exist because every clause in them represents a transaction that went sideways without it. Setting aside the boilerplate means giving up the institutional memory built into the standard contracts.

The Custom Contract Might Not Be As Airtight As You Think

Seller-drafted commercial contracts create a false sense of control. The seller thinks that since they put the contract together, it's an automatic win. That logic breaks down the moment a buyer's attorney starts reading.

Standard commercial contracts carry decades of transactional friction built into every clause. The Arizona Department of Real Estate (ADRE) boilerplate and the AIR CRE standard forms are the two most recognized options in this market. Every contingency, every timeline, every disclosure requirement exists because someone got burned without it. Those forms generally protect both sides with known, predictable language, and both parties typically understand what they are signing.

When a seller substitutes a custom contract, you lose some of that predictability. The document may look thorough, but it can carry gaps the seller doesn't see. It was drafted to protect the seller's stated interests, not to anticipate every move a sophisticated buyer makes once due diligence opens.

A buyer's attorney reviewing a seller-written contract will find missing boilerplate. Contingency language that reads as airtight to a layperson contains exit ramps the seller never intended to grant. The buyer finds them, and the seller may not realize they left these openings until weeks into the deal.

The Cost of Vague Contingency Language

The problem is typically asymmetric expertise rather than bad faith.

Custom contracts drafted years ago, even by competent attorneys, lack updated contingency structures. A buyer's team will spot timelines that reset differently than the seller assumes. They will also catch financing contingencies that expire on an untracked schedule, along with review periods that stay open longer than intended.

Here's what most sellers miss: they believe that once the due diligence window closes, the buyer is locked in. Let's say the contract language is vague about what triggers that lock-in. That could potentially allow the buyer to walk and take the earnest money with them. Even if the seller acted in good faith and didn't intend to leave that opening, they won't have recourse.

The fallout from these deals coming apart can be painful. You accepted the offer and held the property off the market for maybe a month or more. It's possible you even turned down other offers to accept one from a buyer willing to use your custom contract. That's a significant financial impact because the seller relied on a contract that didn't say what they thought it said.

What a Deal Without Disclosures Looks Like in Practice

Over more than two decades, I've handled commercial transactions across retail, industrial, medical, and mixed-use assets in Lake Havasu City and the surrounding corridor. In my experience, the deals that generate the most post-closing friction are rarely the ones with difficult negotiations. It's typically the ones where known information failed to surface until closing day.

A transaction involving a commercial property in Anthem illustrated how this plays out. The deal moved forward without standard HOA addendums and without a full disclosure package. The parties agreed to follow "what's normal in Maricopa County," a phrase that sounds reasonable until no one can agree on what normal means.

Fees that belonged in the disclosure package arrived at the closing table instead, and documentation came in late. An escrow officer also went on leave, adding to the time pressure. Then a $6,000 fee landed without warning. Whether it belonged to the buyer or the seller depended on contract language that was never clearly written.

Read my post about the Anthem deal to learn more about how this played out. It covers the issues with the seller-drafted PSA and the lessons the buyer learned in the process.

"A lot of times people won't do disclosures or HOA addendums. They'll want to use their own contract, one their attorney made 10 or 15 years ago. I do like using the Arizona Department of Real Estate boilerplate commercial contracts, or the AIR forms. They just cover everything. The buyer said it himself: I don't want to buy another piece of property without disclosures or an HOA addendum. It just leaves everything up in the air." – Randy Shuffler, Founder and Commercial Real Estate Agent, Lake Havasu City Commercial

Estoppel Agreements Are Not a Formality

A commercial building with long-term tenants, no written leases, and no estoppel agreements isn't a clean deal.

The buyer assumes they are acquiring a stable income stream. What they are actually acquiring is a verbal history that neither party can independently verify at closing. Disputes over deposit amounts, rent terms, and occupancy status don't surface until escrow. By then, the deal is at risk.

Estoppel agreements are the answer to this issue. Each tenant signs a document confirming their deposit amount, rent, lease term, and current occupancy status. That signed record becomes the legal baseline for the transfer. Without it, closing day becomes a negotiation about what everyone believed the terms were.

The estoppel requirement is one of the most consistently skipped protections in commercial transactions, and it generates some of the most expensive post-closing disputes. For a closer look, read my piece about a $700,000 deal that almost fell apart because there were no leases. It is a case study in how you can salvage these deals with estoppel certificates.

"When you do a commercial sale, you get an estoppel agreement. You have the tenants sign it stating what the deposit is, the terms, everything. So it's not like when you close, and they say, 'That's not true. I had a $10,000 deposit where everybody thought it was a thousand.' You always get estoppels on commercial deals when there are tenants involved." – Randy Shuffler, Founder and Commercial Real Estate Agent, Lake Havasu City Commercial

What Buyers and Sellers Should Each Do Before the Next Transaction

If you're a buyer and the seller insists on using their own contract, have a professional review it before you sign. It requires a full read by someone who knows what ADRE boilerplate and AIR CRE standard contract language normally covers. Map every contingency to a timeline, and know exactly when each one expires and what triggers it. Resolve any ambiguity in writing before signatures.

For sellers, the instinct to control the paper is understandable. However, a seller-written contract might not have the protections you expect. It may even leave openings that buyers can exploit to their advantage. Standard forms encode institutional memory about what goes wrong. Consult a qualified real estate attorney before rejecting the boilerplate.

The Arizona Department of Real Estate also maintains consumer resources on disclosure obligations for commercial transactions. Buyers and sellers should review these resources before going under contract.

Common Questions About Seller-Drafted Contracts in Arizona

Why do seller-drafted commercial real estate contracts often backfire?

Sellers draft contracts to protect their stated interests, but it's hard to anticipate how a buyer's attorney will read the document. Custom contracts frequently lack updated contingency structures, disclosure requirements, and earnest money lock-in mechanics that standard forms include by default. Buyers who know what to look for find the exits, and the seller often has no contractual recourse once those exits are used.

What makes Arizona ADRE and AIR CRE contract forms more protective than custom drafts?

The Arizona ADRE boilerplate and AIR CRE forms reflect decades of transactional experience gathered from real deals. Each clause addresses a documented failure mode, which gives both parties a tested foundation to build on. Standard forms carry institutional memory that protects both sides, and that accumulated knowledge is exactly what makes them valuable.

What happens if a commercial contract is missing an HOA addendum?

An HOA addendum discloses fees, rules, and financial obligations tied to the property's association. Without it, buyers encounter undisclosed fees at the closing table with no contractual basis to dispute who owes them.

What does an estoppel agreement verify in a commercial sale?

An estoppel agreement is a document each tenant signs to confirm their deposit amount, current rent, lease term, and occupancy status. This signed confirmation creates a verified legal baseline for the transfer, so the buyer knows exactly what they are acquiring. Without estoppels, closing day can turn into a dispute over the actual tenancy terms, and those disputes rarely resolve quickly or inexpensively. 

Can a buyer legally walk from a deal using gaps in a seller-drafted contract?

Yes.  These contracts may have vague language about the contingency period or contingencies. That can leave gaps that let the buyer walk away and recover their earnest money. Sellers often discover this exposure only after the chance to renegotiate has passed. The best time to identify and close those gaps is before signatures, when you can still adjust every term.

How long does it typically take for disclosure problems to surface in a commercial deal?

Disclosure gaps usually surface during due diligence or at the closing table, typically three to six weeks into the transaction. By then, the property may have been held off market, backup offers may have expired, and the seller's negotiating position may be weaker. Reviewing disclosures early can help avoid this.

What role do Arizona disclosure requirements play in commercial contract disputes?

Arizona law imposes specific disclosure obligations on sellers in commercial transactions. The ADRE-approved forms are designed to satisfy those requirements by default. Custom contracts drafted without current ADRE disclosure standards can leave gaps that buyers and their attorneys use to challenge the deal or renegotiate terms. Standard forms handle compliance automatically, giving sellers a dependable foundation and keeping the transaction moving smoothly toward closing.

What protections do buyers lose when they skip professional review of a seller-drafted contract?

Buyers who skip professional review lose the ability to identify reset timelines, open contingency windows, and missing disclosure protections before they sign. Addressing ambiguous language after execution is far more expensive than mapping the contract before signatures. A professional review costs a fraction of the earnest money exposure created by signing a contract with unresolved gaps.
