Due Diligence Checklist: Reviewing Real Commercial Real Estate Purchase Agreements

Real Estate Due Diligence Report Review. A Complete Checklist

A real estate due diligence report review is the structured examination of a property's legal, financial, and physical facts before you commit to buying it. For a commercial deal you review the property description and title, the purchase price and payment terms, the inspection and due diligence period, existing leases and tenant rights, environmental findings, and every closing condition. This guide gives you the checklist to run that review yourself and reach a sound decision.

Buying commercial real estate is one of the largest financial commitments a business makes. Whether you are acquiring an office building, a warehouse, or a retail center, the purchase agreement is the foundation for the whole transaction. For commercial, operations, and finance teams tasked with reviewing these agreements, knowing what to look for protects your organization from costly mistakes and unforeseen liabilities.

Commercial deals differ substantially from residential ones. The values are higher, the terms more complex, and the potential for hidden risks greater. You may not have formal legal training, yet your part in the due diligence process is critical. This guide walks you through the elements to examine when you review a commercial real estate purchase agreement.

How do you review the property description and title?

The first section to scrutinize is the property description. It should include the complete legal description, not just the street address. Confirm the description matches the property your company intends to buy by cross-referencing it with survey documents and title reports. Any discrepancy, however minor it looks, can cause problems at closing or later when you sell or refinance.

Title review is equally important. The agreement should state that the seller will deliver clear and marketable title, free from liens, encumbrances, and claims. Request a preliminary title report early and read it carefully for recorded easements, covenants, or restrictions that could limit how your business uses the property. Run a public records search on the parcel to surface judgments, tax liens, or notices of pending action that the seller may not have disclosed. If the property is held in a trust arrangement, review documents such as a Land Trust Deed to see the ownership structure and confirm the seller has authority to convey title.

What should you check in the purchase price and payment terms?

The financial terms deserve close attention. Beyond the stated price, examine how and when payments will be made. Commercial deals often involve earnest money deposits, which show your commitment but also put your funds at risk if the transaction collapses under circumstances not covered by contingencies. Know the conditions under which the deposit becomes non-refundable.

If your company plans to finance the acquisition, the agreement should include a financing contingency that protects you if acceptable financing cannot be arranged. This contingency should state the loan amount, interest rate range, and timeframe for securing funds. Without it, you could lose your deposit if financing falls through. Some deals involve seller financing or a bank guarantee, in which case reviewing an Open Bank Guarantee template helps you see the commitments involved.

How long should the due diligence and inspection period be?

A commercial acquisition should always include a due diligence period during which your company can investigate the property in full. This window, usually 30 to 90 days, lets you conduct inspections, review financial records, examine leases where the property has tenants, and assess environmental conditions.

The agreement should state the length of the period and your right to terminate the contract if you find material defects. Note whether you must give specific reasons to terminate or whether you have an unrestricted right to walk away. Some agreements require you to identify specific objections and give the seller a chance to cure them before you can exit.

Environmental assessments matter for commercial properties. A Phase I environmental site assessment should be run to identify potential contamination. If problems surface, a Phase II assessment involving soil and groundwater testing may follow. Under the federal environmental liability framework of CERCLA, a new owner can inherit cleanup costs, so the purchase agreement should address who pays for these assessments and what happens if contamination is found.

How do you review existing leases and tenant rights?

If you are acquiring an income-producing property with tenants, the agreement must set out how leases will be handled. You will typically receive an assignment of all leases, along with security deposits and any prepaid rent. Review the rent roll and request copies of every lease to verify the terms, rental rates, and expiration dates.

Check whether any tenants hold options to purchase the property, rights of first refusal, or expansion rights that could limit your future flexibility. Some leases include subordination agreements. A Landlord Subordination Agreement can affect the priority of your lender's mortgage against tenant rights, which becomes important if foreclosure ever arises.

Examine the estoppel certificates that tenants provide. These documents confirm the terms of their leases, the rent paid, and whether the landlord is in default on any obligations. Any gap between an estoppel certificate and the actual lease should be resolved before you close.

What do the seller's representations and warranties cover?

The seller's representations and warranties are promises about the property's condition and legal status. Common ones confirm the seller owns the property, that there are no undisclosed liabilities, that the property complies with zoning laws, and that building systems work.

These representations give you grounds for recourse if they prove false. Many commercial agreements, though, include an "as is" clause that limits the seller's liability for property conditions. Where the agreement uses such language, your inspection and diligence become even more important, since your recourse after closing for problems you missed may be narrow.

Which closing conditions and contingencies should you confirm?

The agreement should list every condition that must be met before closing. Beyond financing and due diligence contingencies, these might include obtaining permits or approvals, the seller completing agreed repairs, or the property being vacant by a set date.

Review the timeline closely. Commercial closings often run 60 to 120 days, and the agreement should set deadlines for each contingency and for closing itself. Know what happens if a deadline is missed and whether extensions are automatic or need mutual agreement.

How are closing costs and prorations handled?

Commercial deals carry substantial closing costs, and the agreement should say which party pays each item. Common costs include title insurance, escrow fees, recording fees, and transfer taxes. In some markets custom dictates how these are split, but everything is negotiable.

Prorations set out how ongoing expenses like property taxes, utilities, and insurance are divided between buyer and seller based on the closing date. The agreement should fix the proration date so both sides know their share.

What environmental disclosures should you require in a commercial property purchase agreement?

Environmental disclosures are central to a real estate due diligence report review. You should require the seller to disclose any known contamination, hazardous materials, underground storage tanks, or prior environmental violations. Request copies of Phase I and Phase II environmental site assessments where available, along with remediation records or ongoing compliance obligations. The purchase agreement should include seller representations on environmental compliance and allocate responsibility for pre-existing contamination. Consider requiring soil and groundwater testing if the property previously housed industrial operations, gas stations, or dry cleaners. These disclosures protect your organization from unexpected cleanup costs and potential liability under federal and state environmental laws.

How do you structure earnest money deposits in commercial real estate transactions?

Structuring earnest money deposits in commercial real estate deals means paying attention to timing, amounts, and release conditions. Buyers typically place one to five percent of the purchase price into an escrow account on contract execution, with further deposits due after completing due diligence milestones. The agreement should state whether deposits are refundable or non-refundable, when they can be returned, and how disputes over release are resolved. Many contracts tie forfeiture to specific buyer defaults, protecting sellers while leaving buyers reasonable exit options during inspection. Consider an Open Bank Guarantee for larger deals to add security. Confirm your escrow agent is a neutral third party and that deposit terms line up with your financing contingencies and closing timeline.

What title insurance requirements should your commercial property purchase contract include?

Your commercial real estate purchase agreement should require the seller to provide a title insurance policy from a reputable underwriter, protecting you against defects in title, liens, and encumbrances. State the policy amount, typically matching the purchase price, and clarify whether buyer or seller pays the premium. Include a deadline for the seller to deliver a preliminary title report, usually within 10 to 15 days, so you have time to review and object to any exceptions. Require standard coverage and consider extended coverage that guards against survey errors, unrecorded easements, and access issues. Confirm the title company will issue an owner's policy at closing to give you long-term protection for the investment.

When should you walk away after a due diligence report review?

The point of a due diligence report review is to inform a clear buy or walk decision before the money moves. Walk away, or renegotiate the offer, when the review turns up a material title defect the seller cannot clear, environmental contamination with open-ended cleanup exposure, tenant rights that undercut the income you are paying for, or representations that do not survive verification. Fold each finding back into your price, your contingencies, and your closing conditions so the current agreement reflects what you actually found. A thorough review is often the difference between a sound deal and an expensive one.

Frequently asked questions about real estate due diligence report review

What does a good due diligence period look like heading into 2026? Rising interest rates and tighter lending have pushed many buyers to negotiate longer windows, often at the 90-day end of the range, so there is time to complete research on financing, environmental findings, and tenant income before deposits go hard.

How is reviewing a commercial sale different from a home purchase? A home purchase turns on a short inspection and a disclosure form. A commercial sale layers in rent rolls, estoppel certificates, environmental assessments, and zoning research, so the review is broader and the stakes higher.

What research should I complete before signing? Search public land records for liens and easements, verify zoning and permitted use with the local authority, confirm the rent roll against actual leases, and commission a Phase I environmental assessment. Each check feeds directly into the price and contingencies you agree.
