Commercial real estate transactions in 2026 are increasingly defined by diligence. Higher borrowing costs, more selective capital, and tighter underwriting have changed how buyers evaluate deals. Investors, lenders, and equity partners are examining risk more closely, and the physical and environmental condition of a property has become a central factor in how assets are priced and negotiated.
The most common tools buyers use to evaluate that risk are Property Condition Assessments (PCA), Phase I Environmental Site Assessments (ESA), and Zoning Reports. When these reports uncover deferred maintenance, aging building systems, potential environmental concerns, or zoning limitations affecting use, the findings can quickly influence negotiations.
For sellers, the challenge is timing. When issues surface during the buyer's diligence window, the seller is often forced into a reactive position negotiating repairs, credits, or price reductions to keep the transaction alive.
That dynamic is why many brokers now encourage sellers to complete engineering and environmental assessments before bringing a property to market.
Getting Ahead of Buyer Diligence
Seller-initiated due diligence typically includes a PCA to evaluate building systems and capital needs, along with a Phase I ESA to identify potential environmental risks. Zoning reports are completed early as well to confirm the property's legal use and help prevent potential delays with municipalities. Completing these reports in advance allows sellers to understand the same issues buyers and lenders will examine during the diligence process.
That early visibility provides options. Some owners choose to make targeted repairs or upgrades before marketing the property. Others incorporate anticipated capital costs into their early discussions so buyers can account for them in their pricing and underwriting from the beginning.
Eric Paulsen, COO of Kidder Mathews, says brokers often encourage sellers to complete these diligence steps early.
"Most buyers are going to do their own PCA and Phase I ESA anyways," Paulsen says. "If the seller understands the condition of the property upfront, they have time to address issues and avoid surprises once the transaction is under contract.And just as importantly, it also maintains some of the leverage with the seller."
Completing environmental diligence early can also prevent delays. Phase I reports sometimes identify concerns that require additional investigation or documentation, and addressing those issues before marketing can help keep transactions moving once a buyer is in place.
Reducing Retrades
Late discoveries during inspections frequently lead to a retrade. This occurs when a buyer returns during diligence seeking price reductions or concessions after new information changes their underwriting.
Common examples include roof replacements, aging HVAC systems, or other building components nearing the end of their useful life. Environmental concerns uncovered in a Phase I report can also introduce uncertainty that slows negotiations.
"If you already understand the condition of the roof or HVAC and what it costs to replace it, buyers can account for that in their purchase price from the beginning," Paulsen says. "That makes the transaction run smoother and reduces the likelihood of retrades."
Early diligence helps eliminate surprises that can disrupt negotiations or create uncertainty for lenders and equity partners.
Maintaining Control of the Process
Seller-initiated diligence also helps maintain control of the transaction narrative. When buyers are the first to uncover property or environmental issues, they often shape the discussion around risk and capital needs.
By contrast, when sellers complete a PCA, Phase I assessment, and zoning report before marketing the property, they can frame those issues in advance and present a clearer picture of the asset's condition.
Some buyers may still conduct their own inspections, while others may rely in part on the seller's reports. In either case, early diligence establishes expectations before negotiations begin.
In today's diligence-driven CRE market, the party that controls the information often controls the negotiation. Sellers who complete due diligence before going to market enter the process with a clearer understanding of risk, capital needs, and pricing.
Instead of scrambling to respond to issues uncovered during buyer inspections, they can address them early, set expectations, and keep transactions moving. In many cases, that preparation is the difference between a smooth closing and a late-stage retrade.
