Main Facts
More than five years after the COVID-19 pandemic fundamentally disrupted the white-collar workplace, forcing a massive migration toward remote and hybrid setups, the commercial real estate (CRE) sector is confronting a new, insidious crisis. Even as office vacancy rates begin to stabilize and even decline in more than half of major U.S. metropolitan areas, the vast majority of commercial landlords are experiencing a continuous compression of their profit margins.
The root cause is a painful economic mismatch: operating expenses are outpacing revenue growth by a wide margin. According to a comprehensive analysis of office properties backing Commercial Mortgage-Backed Securities (CMBS) conducted by data firm Trepp, median total operating expense growth has outpaced revenue growth every single year from 2021 through 2025.
While office vacancies have ticked downward due to companies coaxing employees back to physical desks, landlords are finding that higher occupancy does not automatically equate to higher profitability. Day-to-day building operations have grown exponentially more expensive, driven by historic spikes in property insurance and utilities. Consequently, Net Operating Income (NOI)—the lifeblood of commercial real estate valuation—has been squeezed to an anemic 0.2% annualized uptick across the nation.
When property revenues crawl upward at a meager 1.3% annualized rate while operational costs surge by 2.7% annually, the math leaves little room for error. For countless building owners, the post-pandemic recovery has transformed into a financial endurance test, with many properties teering on the brink of distress, loan default, or forced lender takeover.
Chronology: A Five-Year Timeline of Margin Compression
To understand how the modern office market arrived at this precarious juncture, it is vital to trace the financial trajectory of commercial properties year by year following the seismic shocks of 2020.
2021: The Immediate Aftermath and Shifting Baselines
As the world attempted to emerge from pandemic lockdowns, corporate tenants began reevaluating their physical footprints. Remote work was no longer a temporary emergency measure; it was rapidly hardening into a permanent cultural shift. Landlords faced soaring vacancies and plummeting demand. In Trepp’s initial property sample size of 3,599 CMBS-backed buildings, revenues stalled while operational costs began their stealthy ascent, catching many property managers flat-footed as inflation started rearing its head nationwide.
2022–2023: Inflation Meets the Remote Work Hangover
During these middle years, the macroeconomic landscape deteriorated for real estate operators. Inflationary pressures spiked the costs of basic building inputs, from cleaning supplies to HVAC maintenance. At the same time, companies downsized their office spaces upon lease renewals. Landlords were forced to offer unprecedented concessions—such as months of free rent and massive tenant-improvement (TI) allowances—just to retain tenants or fill empty cubicles. Expenses far outstripped revenues, marking the first consecutive years of true negative operating leverage for many portfolios.
2024: The Bifurcated Market and Insurance Shocks
By 2024, the "flight to quality" was well underway. Tenants gravitated toward top-tier, amenity-rich trophy buildings, leaving older Class-B and Class-C assets struggling to maintain baseline occupancies. Concurrently, property insurance premiums experienced an unprecedented, nationwide systemic shock. Premium renewals routinely jumped by double-digit percentages, compounding already elevated utility and payroll expenses.
2025–2026: The New Normal of Stagnant NOI
Entering 2025 and looking toward 2026, the Trepp model reveals that while the hyper-inflationary spike in operating expenses has begun to moderately decelerate, revenue growth has slowed down in tandem. Annual NOI growth logged its second consecutive year of negative territory. Meanwhile, Trepp’s tracking sample shrank from 3,599 properties in 2021 down to 2,266 properties by 2026—a stark statistical reflection of the buildings that have been paid off, liquidated, distressed, or seized by lenders because their revenues could no longer service their debt obligations.
Supporting Data: The Numbers Behind the Squeeze
The scope of the financial pressure facing office landlords is laid bare by Trepp’s granular metrics. Over the five-year study period from 2021 through 2025, the implied cumulative growth rate for operating expenses reached a staggering 14.3%, while total revenues limped upward by just 6.7%. The resulting cumulative NOI growth over the entire half-decade scraped by at a meager 1.0%.
To arrive at these insights, Trepp’s methodology utilized a strict year-to-year matched-property sample. Properties were removed from the tracking pool if they ceased financial reporting, lacked required metrics, underwent debt payoff, were liquidated, or faced special servicing and lender foreclosure.
Expense Drivers Breakdown
The upward trajectory of operating costs was not uniform; certain operational line items acted as primary catalysts for the margin squeeze:
- Property Insurance (The Leading Culprit): Property insurance has become the fastest-growing expense across every U.S. region. It surged at a median rate of 6.1% annually, compounding to a massive 34.6% increase over the five-year period. Regional disparities were stark: the Pacific U.S. bore the brunt of climate- and risk-driven insurance hikes, logging a median annual increase of 9.2%. Conversely, the Middle and South Atlantic regions saw the "lowest" increases, though still painful at 4.6% annually.
- Utilities: Ranking as the second-leading cost driver, utility expenses climbed 4.9% annually, resulting in a cumulative 27.1% jump between 2021 and 2025.
- Maintenance and Payroll: Day-to-day building upkeep continued to mount. Annual building repairs increased by 3.2%, payroll and employee benefits grew by 3.3%, administrative costs rose by 2.7%, and professional management fees ticked up by 1.3%.
Regional Performance
Geographically, the financial bleeding was not distributed evenly. The pain was heavily concentrated in specific regions of the country:
- The Midwest: Illinois, Indiana, Michigan, Ohio, and Wisconsin struggled the most severely, seeing aggregate NOI drop by 1.4% over the five-year span.
- The South Central & New England: The West South Central region (Arkansas, Louisiana, Oklahoma, and Texas) saw NOI decrease by 0.5%, while New England experienced a 0.1% drop in NOI.
Official Responses and Industry Context
Real estate analysts, brokers, and economists point out that Trepp’s figures actually understate the true financial burden resting on office landlords. Crucially, the operating expense data does not include capital expenditures (CapEx)—the massive, discretionary, and often mandatory cash outlays owners have had to deploy to keep their buildings competitive.
In the post-pandemic era, corporate tenants have used upgraded amenities, state-of-the-art wellness features, modern HVAC systems, and convenient locations as leverage to convince employees to abandon their home offices and return to in-person work. Consequently, owners of trophy and Class-A buildings have been forced to shell out millions of capital dollars to redesign lobbies, install touchless technologies, build high-end tenant lounges, and add outdoor collaborative spaces.
Even in tight markets like Manhattan—where Class-A space has become scarce and expensive, pushing leasing activity to spill over into Class-B properties—landlords face an unavoidable reality: you have to spend money to make money.
However, spending millions on capital improvements creates a dangerous liquidity trap. Every dollar funneled into tenant-attracting upgrades layers on top of already ballooning maintenance, payroll, and insurance overhead. When revenue fails to scale proportionally, owners find themselves trapped in a cash-flow negative loop.
Implications: What This Means for the Future of Commercial Real Estate
The persistent widening gap between office operating expenses and property revenues carries profound long-term implications for investors, lenders, municipal governments, and urban planners.
1. Accelerating Distress and Loan Defaults
As NOI remains stagnant or negative, property valuations are undergoing continuous downward recalibration. Landlords who secured CMBS or traditional bank loans based on pre-pandemic valuations are facing severe refinancing walls. With cash flows insufficient to cover debt service coverage ratios (DSCR), a growing wave of owners are simply handing the keys back to their lenders—explaining why hundreds of properties dropped out of Trepp’s tracking sample via foreclosure or liquidation.
2. The Great Bifurcation Deepens
The data confirms that the office market is no longer a monolith. Owners of outdated, unamenitized Class-B and Class-C buildings are trapped in a death spiral: they lack the capital to upgrade their properties to attract modern tenants, yet without those upgrades, they cannot raise rents or boost occupancy to cover soaring insurance and utility bills. Meanwhile, well-capitalized institutional owners of top-tier trophy towers can absorb higher operational costs, leveraging amenities to capture shrinking corporate demand.
3. Municipal Tax Base Pressures
Cities that rely heavily on downtown commercial property tax revenues are facing an impending budget reckoning. As office building valuations plunge due to chronically low NOI, municipal tax assessments will inevitably drop, forcing local governments to either cut public services or shift the tax burden onto residential property owners.
4. Evolution of Asset Repurposing
Ultimately, the persistent margin squeeze is accelerating conversations around adaptive reuse. For properties where operating expenses permanently outstrip revenue potential, traditional office leasing is no longer viable. Expect to see an acceleration of distressed office buildings being converted into residential apartments, life sciences labs, or mixed-use cultural hubs—a complex, costly process, but increasingly the only viable escape hatch for drowning landlords.
