Office 2026: The Bifurcation Has Become a Chasm — and the Data Is Finally Getting Specific
The national office narrative has been stuck on a single thesis for three years: vacancy is high, remote work persists, and the asset class is structurally challenged. That thesis is accurate as far as it goes — national office vacancy at 19.8% is real, and the commodity office market is not recovering on any near-term timeline. But the narrative has become so dominant that it's now obscuring a more nuanced story about where office actually stands in mid-2026, who is leasing, what they're paying, and what the forward indicators are telling sophisticated operators.
The attendance data has shifted:
Kastle Systems' Back-to-Office Barometer — the most widely tracked measure of actual badge swipe data in US office buildings — reported average occupancy across the top ten US markets at 62.4% of pre-pandemic baseline as of June 2026. That's the highest reading since March 2020. More importantly, the trend line has been positive for six consecutive quarters. The firms driving the improvement are identifiable: financial services, legal, and professional services firms that have implemented or strengthened in-office requirements. Technology firm attendance remains lower but has stabilized.
For office landlords, this data matters because it feeds lease renewal decisions. Tenants who are actually using their space are more likely to renew. Tenants who have been on holdover with mostly empty offices are more likely to contract or exit.
The flight to quality: new lease data tells the story:
CBRE's Q1 2026 leasing report shows that 74% of new office leases signed nationally were in buildings constructed or substantially renovated after 2015. That statistic — nearly three-quarters of all new leasing in the newest 15% of stock — is the clearest quantification of the flight-to-quality thesis. Landlords of sub-2015 vintage product are competing for the remaining 26% of new lease demand, against each other and against a deep sublease market.
Effective rents on new leases in Class A+ trophy product in gateway markets are actually growing: Manhattan Midtown South is printing $85–$115 per square foot on new ten-year leases, with TI packages of $100–$140 per square foot. Boston Seaport is at $72–$88 per square foot. Miami Brickell, as noted in the Florida piece, has crossed $75 per square foot with a limited pipeline and a growing financial services tenant base.
The conversion math is becoming real:
For commodity office — sub-2000 vintage, non-amenitized suburban product — the most credible underwriting thesis is no longer leasing recovery. It's conversion. The federal adaptive reuse tax credit program, combined with state-level incentives in Illinois, Ohio, New York, and California, has made the office-to-residential conversion math viable for the first time in many markets. Conversion completions hit 12,400 units nationally in Q1 2026 — a record quarterly figure — with Chicago, Cleveland, Washington DC, and Denver leading. The pipeline of announced conversions is approximately 3x the current completion rate, suggesting the conversion wave accelerates through 2027–2028.
The underwriting framework for office in 2026:
Three distinct underwriting approaches apply to three distinct office segments:
Trophy Class A+ in gateway markets: underwrite as a core income asset with rent growth assumptions of 3%–6% per year, sub-10% vacancy, and exit caps of 5.5%–6.5% in 2028–2030. This is the segment where institutional capital is actively competing.
Class A suburban (post-2010 vintage, amenitized, major employer submarkets): underwrite as a value-add play with stabilization risk — 15%–22% vacancy, flat rents, meaningful TI exposure on new leases, and an exit that depends on specific submarket recovery rather than market-wide improvement. Returns require patience and capital.
Class B/C commodity office: underwrite to conversion or redevelopment. The going-concern leasing thesis requires assumptions that the market is not currently supporting. Model the conversion pathway explicitly, including entitlement risk, construction cost, and the gap between as-is value and conversion-complete value.
The one-line read: Office is not one market. It is three markets with three different underwriting frameworks. The error is applying one framework to all three.
Klyvora note: Office underwriting is among the most model-intensive work in CRE — TI modeling, lease-by-lease rollover analysis, conversion feasibility, and submarket comp tracking all require structured, ongoing analytical effort. Klyvora's offshore underwriting teams are built to handle office-specific analytical cadences so your investment team can move faster on the deals that actually work.
