The AI buildout has turned the old-school data center real estate investment trusts (REITs) from a niche real estate subsector into one of the clearest ways to own the physical infrastructure behind the artificial intelligence boom, and the numbers are starting to back that up.

Iron Mountain: A REIT Growth Idea, Thanks To Data Centers And More
Iron Mountain gets a buy rating for my initial coverage, driven by both a compelling growth case and the dividend story as well. Both the top and bottom lines have seen growth catalysts lately.

My 5 Greatest REIT Winners Of All Time
Iron Mountain, Tanger, Four Corners, Essential Properties, and Chatham Lodging delivered outsized REIT returns by exploiting price-value gaps during market panics. My disciplined value investing approach focuses on durable business models, strong balance sheets, and buying below intrinsic value, not market timing or headline chasing. IRM and SKT now trade at premium valuations, while EPRT and FCPT remain attractively priced with solid growth and conservative payout ratios; CLDT reached fair value and was exited.

REITs: Cheap, Unloved, And Finally Showing Life
REITs have refused to break in 2026 despite oil-driven inflation pressure, rising Treasury yields, and a Fed narrative that flipped from multiple rate cuts to potential hikes. The “Rates Up, REITs Down” regime has weakened, with REIT-rate correlations falling sharply as fundamentals, strategy, capital allocation, and valuation catalysts increasingly drive performance. M&A has helped break the rate-driven narrative, validating public-market discounts to NAV and proving that REITs can unlock value through consolidation, privatizations, and strategic alternatives.
