The hidden tax reset reshaping industrial deals

Good morning. Welcome to Small Bay List!

Today, we feature a great opex breakdown on property taxes, using Denver as a case study. Many operators and tenants are facing similar issues across the country.

Now, let’s get to it!

Over the past 5 to 10 years, one of the more nuanced shifts in Denver’s industrial market has not just been rent growth or new development. It has been the way property taxes have evolved at the asset level.

Looking at individual properties over time gives a clearer view than market averages, especially in small-bay and infill industrial assets where operating costs directly impact both ownership performance and tenant decision-making. While this is a limited sample, it helps illustrate how property tax behavior can vary based on reassessment timing, valuation changes, and broader market conditions.

Across three industrial properties in the Denver metro area, a consistent pattern emerges. Property taxes do not always move in a straight line. They can remain stable for extended periods, then adjust more abruptly, sometimes shifting the cost structure of a deal in ways that are not fully anticipated.

At 6066 E 49th Ave in Commerce City, property taxes stayed relatively stable for nearly a decade. From 2014 through 2022, increases were gradual and predictable, the type of trend many owners and tenants build into their expectations.

That stability changed in 2023, when taxes stepped up sharply in a single reassessment cycle. Although there was a slight adjustment downward the following year, taxes increased again in 2025, ultimately settling at a level materially higher than the prior period.

Long-term stability can create a sense of predictability. But when reassessments occur, they do not simply extend prior trends. They reset the baseline.

A different pattern appears at 3596 N Moline St in Aurora. Here, taxes increased steadily over several years, broadly tracking market appreciation. Around 2021, that gradual growth shifted into a more pronounced increase, moving the property into a higher tax range that continued through 2025.

Even with minor fluctuations, the overall level stayed elevated. Instead of reverting, the property established a new ongoing baseline.

This kind of shift from gradual growth to a step change is becoming more common as reassessments catch up to market value.

At 3795 Paris St in Denver, the pattern is more front-loaded. Property taxes rose quickly in the early years, nearly doubling in a relatively short period, then continued increasing at a slower pace with periodic fluctuations.

While there are moments of decline, the overall level remains meaningfully higher than where it started. Even without a single sharp jump, cumulative increases over time can permanently shift the cost structure of an asset.

What the Three Properties Show Together

Taken together, these examples point to a consistent pattern. Property taxes in industrial assets do not move in linear increments. They move in phases, including periods of stability, sudden reassessment adjustments, and new baseline resets that persist.

While the timing varies by asset, the outcome is consistent. Tax burdens tend to “step up” rather than drift upward smoothly, and once they reset, they rarely revert.

This is not a Denver-specific anomaly. It reflects a broader structural shift in how industrial assets are being reassessed across U.S. markets following several years of rapid appreciation and compressed cap rates.

In other words, what shows up in Denver at the property level is an early, visible expression of a national recalibration in operating expenses.

This pattern aligns with observations from major U.S. industrial research, which have noted that operating expenses, particularly property taxes, are adjusting upward as reassessments catch up to prior valuation growth. Across multiple markets, the lag between market appreciation and tax reassessment is narrowing, resulting in more pronounced step changes in carrying costs rather than gradual increases.

Implications for the U.S. Industrial Market

For owners, this shift directly impacts net operating income stability. If reassessed tax increases are not fully recoverable through lease structures, especially in triple net environments, margin compression can occur faster than historical underwriting models would suggest.

For tenants, particularly in small-bay and infill industrial space, occupancy cost is increasingly disconnected from historical expense baselines. Even when base rent appears stable, total occupancy cost may rise meaningfully after reassessment cycles reset tax obligations.

For investors, this introduces a structural underwriting gap. Relying on trailing tax expenses can understate forward-looking operating costs, especially in markets that experienced accelerated appreciation between 2020 and 2022. In these environments, historical expense patterns are becoming less predictive of future performance.

In other words, what shows up in Denver at the property level is an early, visible expression of a national recalibration in operating expenses, as observed through industrial deal flow and underwriting patterns tracked by The Warehouse Hotline.

The takeaway is simple. Property taxes do not just increase. They reset.

And when they reset, they do not just change annual expenses. They change underwriting assumptions, deal structure, and long-term asset performance across the U.S. industrial market.

Looking at individual properties makes that shift visible. Scaling it across markets shows it is no longer local behavior. It is structural and increasingly reflected in the industrial transactions and underwriting patterns seen across The Warehouse Hotline’s advisory work.
