Best Specialty REITs 2026: Iron Mountain, Lamar, Safehold, OUTFRONT Graded

How to Read This Ranking

Iron Mountain (75) just printed the group’s best quarter (AFFO +22%, growth businesses +50%) as its records-to-data-center transformation compounds, graded with its below-investment-grade leverage honestly weighed. Lamar (74) owns the irreplaceable American roadside: 360,000 billboard faces, 75% local advertisers, digital conversion economics. Safehold (60) is the century-bond experiment, contractually bulletproof ground rent wrapped in maximum rate duration. OUTFRONT (58) is the urban cousin: transit contracts and two dividend resets in five years, an urban-recovery trade more than an income holding.

The duration lesson: Safehold proves the lease-duration spectrum at its extreme: 99-year cash flows trade like ultra-long bonds no matter how safe the rent, the same duration mathematics that governs investment-grade bond pricing.
