What Should You Include in a Commercial Real Estate Purchase Agreement?

 Posted on March 30, 2026 in Real Estate

A commercial real estate purchase agreement sets the terms of the deal, defines what each side is responsible for, and protects you if something goes wrong. Getting it right matters more than most buyers and sellers realize.

A weak or incomplete agreement can cost you time, money, and the deal itself. If you are buying or selling commercial property in 2026, we can help. The Cook County, IL real estate lawyers at Whitacre & Stefanczuk LTD can make sure your agreement covers everything it needs to.

What Is a Commercial Real Estate Purchase Agreement?

A commercial purchase agreement is a legally binding contract between a buyer and a seller. It spells out the terms of the sale. Unlike a home purchase, which often uses a standard form, a commercial agreement is usually more detailed and built around the specific deal.

Every word in the contract matters. Vague language, missing terms, or poorly written clauses can lead to arguments, delays, or a deal that falls apart at the worst possible time.

What Basic Terms Must Every Commercial Real Estate Purchase Agreement Include?

No matter what type of commercial property is involved, every purchase agreement needs to cover the basics:

• The legal names of the buyer and seller

• A clear legal description of the property

• The purchase price and how it will be paid

• The earnest money deposit amount and when it is refundable

• The closing date and what needs to happen before closing

• What is included in the sale, such as fixtures, equipment, or personal property on the premises

If any of these are missing or unclear, the deal can fall apart or lead to a dispute after closing.

What Contingencies Should an Illinois Commercial Real Estate Purchase Contract Include?

Contingencies protect the buyer from getting stuck in a deal that does not work out as expected. Common contingencies in commercial contracts include:

• A due diligence contingency that gives the buyer time to inspect the property and review financial records, zoning, title history, and environmental issues

• A financing contingency that lets the buyer walk away if they cannot get the funding they need

• An inspection contingency that allows the buyer to back out or renegotiate if the inspection uncovers serious problems

• An environmental contingency that gives the buyer an exit if testing reveals contamination or liability

Without these protections, a buyer could be forced to close on a property with serious hidden problems or lose their deposit if financing falls through.

Why Does the Due Diligence Period Matter So Much With Commercial Real Estate Agreements?

The due diligence period is the window of time after signing but before closing, where the buyer can dig into the details of the property. This is one of the most important parts of any commercial deal.

During this time, the buyer should look into title records for liens or ownership disputes, check zoning to make sure the property can be used the way they intend, and inspect the physical condition of the building. If tenants are in place, the buyer should also review any existing leases carefully. On top of that, checking environmental reports and verifying the accuracy of income and expense statements provided by the seller are critical steps before closing.

This period needs to be long enough to do all of that properly. If it is too short, the buyer may miss serious problems before they are locked into the deal.

What Should a Seller Guarantee in a Commercial Purchase Agreement?

Representations and warranties are statements the seller makes about the property. If those statements turn out to be false, the buyer may have legal options after closing. Under the Illinois Consumer Fraud and Deceptive Business Practices Act, 815 ILCS 505, sellers who make false or misleading statements about a property can face legal liability, which is why getting these representations in writing and in detail matters so much.

Key seller statements typically cover ownership, condition, and legal standing. The seller should confirm they have clear legal ownership and the right to sell. There should be no hidden liens or legal claims against the property, and the property should be in the condition described in the contract. The seller should also confirm there are no pending lawsuits involving the property and that all leases and financial records shared with the buyer are accurate.

The contract should also say how long the buyer has after closing to bring a claim if a false statement is discovered.
