Industrial real estate has a problem most asset classes would kill for: there isn’t enough of it. National vacancy sits below 4%. E-commerce keeps growing. Last-mile distribution space is the most constrained subtype in commercial real estate. And new supply is slowing because the math no longer works for speculative development. For borrowers in the $5M-$30M range, this is the setup.
The Vacancy Numbers Are Historically Tight
Industrial vacancy nationally remains below 4%, according to CBRE’s Q1 2026 U.S. Industrial Figures. To put that in context: a “healthy” industrial vacancy rate is generally considered 5-7%. Below 4% represents a fundamentally supply-constrained market where landlords have significant pricing power and tenants are competing for limited space.
The tightness is most acute in last-mile distribution — small-bay industrial facilities under 100,000 square feet located near population centers. These facilities serve the final leg of the e-commerce supply chain: getting packages from regional distribution hubs to consumers’ doorsteps. Vacancy in this subtype runs below 3% in many major metros, and rents are growing 5-8% annually.
E-Commerce Is Still the Structural Driver
E-commerce now accounts for over 22% of total U.S. retail sales, according to the U.S. Census Bureau’s quarterly e-commerce report. That penetration rate has been climbing steadily since the pandemic accelerated digital shopping adoption, and every incremental point of e-commerce growth requires an estimated 1.25 billion square feet of additional warehouse and distribution space.
The implications for industrial real estate are significant. Even modest continued growth in e-commerce — say, 1-2 percentage points per year — translates to demand for 1.25-2.5 billion square feet of new industrial space annually. Against a supply pipeline that’s contracting, this creates a structural demand-supply imbalance that supports rent growth and cap rate compression for years to come.
New Supply Is Hitting a Wall
Speculative industrial development boomed in 2021-2023, when low interest rates and red-hot demand made new construction highly profitable. That dynamic has reversed. According to JLL’s industrial research, new construction starts have declined sharply as higher interest rates and elevated construction costs have pushed development yields below acceptable thresholds for many sponsors.
The result: the current wave of completions — projects started in the 2022-2023 boom — is delivering now, but the pipeline behind it is thin. By 2027-2028, new industrial supply will drop well below historical averages, further tightening an already constrained market.
Small-Bay Industrial: The Most Underserved Segment
Big-box logistics (500,000+ SF distribution centers for Amazon, Walmart, FedEx) gets the headlines. But small-bay industrial (10,000-100,000 SF) is where the real scarcity exists — and where $5M-$30M borrowers operate.
Small-bay industrial serves a diverse tenant base: local distributors, contractors, light manufacturers, auto shops, food production, and last-mile delivery operators. These tenants are sticky — they build out their spaces, invest in equipment, and renew leases at high rates. Rent growth in small-bay industrial has outpaced big-box logistics over the past three years, and vacancy is tighter.
Institutional buyers focus on $50M+ big-box logistics portfolios. That leaves the $5M-$30M small-bay industrial segment underpriced relative to fundamentals — and underserved by capital. Local banks can’t size the loans. CMBS lenders don’t want the complexity. Bridge and specialty lenders fill the gap.
What This Means for Industrial Borrowers
The industrial investment thesis for 2026 is simple: buy assets in a supply-constrained market, benefit from structural rent growth, and hold through a period where new supply will remain limited. The $5M-$30M segment offers the best risk-adjusted entry point — institutional-quality assets at non-institutional pricing, with fundamentals that support aggressive underwriting.
