Denver Office Towers Sold for 98% Loss: Investor Warning Signals

The commercial property market in Denver has delivered a sobering lesson in value erosion, with two prominent downtown office towers at 621 and 633 17th Street changing hands for a mere £3.2 million in 2025. This translates to roughly £3 per square foot, a staggering decline from their reported valuation of £200 million in 2019. This transaction, noted in passing by industry watchers on platforms like X, underscores a broader crisis in the office sector, where post-pandemic shifts in work patterns, rising interest rates, and economic uncertainty have gutted property values. The scale of this collapse, a near 98% drop in just six years, demands a closer examination of what it signals for urban real estate markets.

Unpacking the Denver Downturn

The sale of these towers is not an isolated incident but part of a wave of distress in Denver’s office market. As of Q2 2025 (April to June), the city has identified 30 office buildings as distressed, with vacancy rates exceeding 40%. Foreclosures and forced sales are accelerating, painting a grim picture of a sector struggling to adapt to a world where remote working remains a persistent norm. Data from Q1 2024 (January to March) already showed a 75% drop in office sales volume compared to the same period in 2023, with total commercial sales declining by 21% to £1.44 billion. This trajectory has only worsened into 2025, as lenders tighten standards and borrowers grapple with maturing loans amid higher borrowing costs.

Historically, Denver’s office market thrived on its status as a growing tech and energy hub. In 2019, valuations like the £200 million for these two towers reflected optimism about urban density and corporate demand. Contrast that with 2025, where the £3 per square foot sale price suggests buildings are barely worth more than the land they sit on. This isn’t just a local anomaly; it mirrors national trends where office spaces are increasingly seen as liabilities rather than assets. Across the US, estimates suggest up to 25 million square feet of office space could be demolished or converted by the end of 2025, against just 13 million square feet of new construction.

Broader Implications for Commercial Real Estate

The Denver case is a microcosm of a sector-wide reckoning. Nationally, office vacancy rates hover around 19.6% as of Q2 2025, with some urban centres faring worse. The shift to hybrid work models has reduced demand for traditional office space, while the cost of retrofitting older buildings to meet modern sustainability and tech standards often outweighs potential returns. Add to this the pressure of interest rates, which have risen sharply since 2022, and property owners are caught in a vice. Many are offloading assets at steep discounts to avoid default, as seen in Denver.

Investors might be tempted to view such sales as bargain opportunities, but caution is warranted. Buildings sold at £3 per square foot are unlikely to yield quick turnarounds without significant investment or a drastic shift in market dynamics. Conversion to residential or mixed-use properties is often floated as a solution, but zoning hurdles, construction costs, and uncertain demand for downtown living complicate this path. Denver’s own data shows that while multi-family and industrial sectors have held up better, with sales declines of less than 10% in Q1 2024 compared to 2023, the office segment remains the Achilles’ heel of commercial real estate.

Key Metrics at a Glance

Looking Ahead: A Market in Flux

What does this mean for the future of urban office spaces? Denver’s fire sale is a warning shot for other cities with similar demographics and economic profiles. Markets like San Francisco and Chicago are already reporting comparable distress, with buildings selling at 30 to 50 cents on the dollar of their pre-pandemic values. The notion of ‘zombie buildings’, properties with low occupancy and dwindling financial viability, is no longer a theoretical risk but a tangible reality. Some projections estimate that up to a quarter of US office space could fall into this category by 2030, representing a potential £450 billion in lost value.

For policymakers and developers, the challenge is twofold: finding viable alternative uses for these spaces and mitigating the knock-on effects on municipal budgets, which often rely on property taxes. For investors, the lesson is clear. The days of banking on urban office towers as stable, appreciating assets are over, at least for now. The Denver transaction, while extreme, is a stark reminder that value in real estate is not immutable; it is tethered to human behaviour and economic tides. If there’s a silver lining, it might be that rock-bottom prices could eventually spur creative redevelopment, though one suspects that’s more hope than certainty at this juncture.

In a market where £3 per square foot is the new benchmark for once-prised assets, a touch of gallows humour might be forgiven. After all, at that price, one could almost buy an office tower as a particularly spacious storage unit. But the underlying reality is far from amusing. Denver’s commercial real estate sector is sounding an alarm that other cities would do well to heed.
