Office Vacancy Is Near Record Highs in 2026 — And the Office Vacancy Impact on Commercial Real Estate Is Just Getting Started
Nearly one in five U.S. office buildings was vacant and unleased entering 2025.

Nearly one in five U.S. office buildings was vacant and unleased entering 2025. The national office vacancy rate hit 19.6% in Q1 2025, the highest on record according to data cited by Kaplan Collection Agency drawing on Cushman and Wakefield research. In the ten largest office markets across the country, the average vacancy climbed even higher — to 21.9%, up from 19.4% just one year prior. This is no longer a pandemic hangover. It is a structural reset, and the ripple effects are now reaching landlords, lenders, city budgets, and rental investors who may never own a single office building.
From Empty Desks to Empty Balance Sheets
The vacancy numbers tell only part of the story. What happens downstream is where the real pressure builds. When offices sit unleased, property values fall. When values fall, loans go underwater. When loans go underwater, lenders tighten credit across their entire commercial real estate portfolios — including multifamily, industrial, and retail assets that have nothing to do with office space.
In Washington D.C., a 2024 analysis from the city's Office of Revenue Analysis found that at least 86% of more than 500 high-value office buildings were projected to lose assessed value at some point between 2020 and 2025. That kind of repricing does not stay contained. It pressures municipal tax revenues, disrupts refinancing timelines, and signals to the broader lending market that commercial real estate risk has not been fully priced in. JPMorgan's 2026 Commercial Real Estate Outlook noted ongoing caution around office exposure, reflecting how seriously institutional lenders are monitoring this sector.
The Refinancing Wall and the Lender Dilemma
Many office loans originated in the low-rate environment of 2019 to 2022 are now maturing or approaching maturity. Owners facing refinancing in today's rate environment are confronting a painful combination: higher borrowing costs and assets worth less than when the loan was first written. Some lenders are extending and pretending — rolling over loans rather than forcing defaults that would crater their own portfolios. Others are quietly tightening underwriting across all commercial asset classes to reduce exposure.
The National Association of Realtors' March 2026 commercial market insights highlighted continued stress across office assets and the broader caution this is creating in CRE lending. For investors in any commercial or residential asset class, tighter lending conditions are a material concern — not an abstract one.
Urban Conversion Is Real but Limited
One frequently cited solution is converting offices to residential use. In theory, unused office floors become apartments, solving both the vacancy problem and housing supply constraints. In practice, the economics are difficult. Floor plate configurations, plumbing requirements, zoning hurdles, and construction costs make most office buildings poor candidates for conversion. The ones that do convert are typically older, smaller buildings in strong residential demand corridors. Conversions are happening — but they will not absorb the volume of vacant space the market is currently carrying.
What This Means For Rental Investors
1. Weak office markets create spillover pressure in urban rental submarkets. Cities with heavy office dependence — particularly those centered on downtown — can see softer apartment absorption, slower rent growth, and reduced foot traffic that affects retail and amenity quality in residential corridors nearby. Investors underwriting deals in CBDs heavy with office space should factor in this demand softness.
2. Lender caution across CRE can tighten credit conditions for everyone. When banks are managing losses or reserves tied to office exposure, they often pull back more broadly. That can mean higher rates, lower LTV ratios, or slower approval timelines on residential investment loans — even for single family rental buyers who have no direct CRE exposure. This is the channel most SFR investors overlook.
3. Markets with diversified employment bases are more insulated. Metros with strong logistics, healthcare, education, manufacturing, and in-migration tailwinds are significantly less exposed to economic softness driven by office weakness than cities where finance, law, consulting, and government contracting dominate local employment. The Southeast, parts of the Mountain West, and mid-tier Sun Belt cities with diversified job bases have shown more resilience, according to JPMorgan's 2026 CRE Outlook.
4. Suburban family-oriented submarkets within affected metros may still perform. Even in metros experiencing downtown office pain, suburban submarkets with strong school districts, access to distributed job centers, and in-migration from higher-cost cities can continue to absorb rental demand. The risk is concentrated in dense corridors that depend on transit and sit adjacent to the CBD — not across the entire metro.
The Charlotte Angle
Charlotte is worth watching specifically. As a major U.S. banking and financial services hub, it sits at the intersection of two pressures: potential softness in downtown office demand and the health of lender balance sheets that are directly tied to the national CRE picture. Prolonged office weakness could affect local employment in financial services, slow downtown office to residential conversion pipelines, and put pressure on lenders with significant CRE books. The practical takeaway for SFR investors in the Charlotte market is to track neighborhood-level demand signals around suburban employment corridors and transit nodes, where the spillover from downtown softness tends to be measurably less severe.
The Bottom Line
The office vacancy story is not just about office buildings. It is about what persistent vacancy at record levels does to the entire commercial real estate ecosystem — valuations, lending, city revenues, and eventually the broader residential investment environment. The investors who navigate this cycle well will be those who understand the connections, not just the headline numbers.
