Why a Pre-Listing Phase I ESA Can Help Owners Protect Value and Avoid Surprises

When preparing to bring a commercial property to market, many owners assume a buyer will complete a Phase I Environmental Site Assessment (ESA) during escrow, particularly when financing is involved.

As a result, sellers often question whether it is worthwhile to obtain an ESA in advance, especially given the typical cost of approximately $2,000. However, this relatively modest investment can provide significant strategic value. Environmental concerns identified late in escrow can delay a transaction, complicate negotiations, or derail a sale altogether.

GM Properties’ Strategic Approach

At GM Properties, we advise owners on whether obtaining a Phase I ESA prior to listing may be beneficial. Factors such as historical property use, tenant operations, and overall transaction goals can all influence whether early environmental due diligence makes sense.

A Phase I ESA evaluates the historical and current uses of a property, as well as surrounding sites, to identify potential environmental risks. Environmental consultants review regulatory records, environmental databases, and prior site activity to determine whether hazardous materials may have been stored, released, or disposed of on the property.

If potential concerns are identified, the report may recommend a Phase II Environmental Site Assessment. Phase II investigations typically involve soil sampling and laboratory testing to determine whether contamination is present. These additional steps can introduce significant time and cost into a transaction. Identifying potential issues early can help owners minimize delays during negotiations and closing.

Insights From Recent Transactions

Through our work with commercial property owners, we have seen how the timing of an ESA can directly affect transaction outcomes.

Facilitating a Fast Close for an Industrial Property

In one multi-tenant industrial transaction, the seller chose to obtain a Phase I ESA before bringing the property to market. One tenant operated an automotive-related business, which can invite additional environmental scrutiny.

The report identified no recognized environmental concerns. By providing the completed ESA to prospective buyers upfront, the seller attracted an all-cash offer and moved efficiently through escrow to closing.

Portfolio Sale Reconsidered After Environmental Findings

In another case, the owners of a four-property industrial portfolio were preparing to sell as part of a broader ownership transition.

Phase I ESAs were completed for all four properties before listing. While three properties returned clean reports, the fourth revealed potential concerns that warranted further investigation.

Because the issue was identified in advance, the owners were able to assess the situation privately and ultimately decided not to move forward with the sale, avoiding complications during negotiations or escrow.

Transaction Disrupted by a Late Environmental Discovery

In a retail transaction, the seller did not obtain a Phase I ESA before listing. During escrow, the buyer conducted its own assessment, which identified potential concerns and recommended a Phase II investigation.

The unexpected findings introduced uncertainty, and the transaction ultimately did not move forward. The seller continues to hold the property.

Bottom Line for Owners

While Phase I ESAs are often viewed as a buyer-driven requirement, they can also serve as a strategic tool for sellers. Obtaining an ESA prior to listing can help identify risks early, support pricing and negotiation strategy, and reduce the likelihood of delays or disruptions during escrow.

For owners preparing to sell, the question is not simply whether a buyer will order a Phase I ESA, but whether addressing environmental risk earlier can help preserve leverage, support a smoother transaction, and reduce the likelihood of late-stage surprises.

GM Properties works closely with property owners to evaluate risk, position assets for market, and navigate complex transaction considerations.
