Key Takeaways
- • REITs outperformed private value-add/opportunistic real estate investments in 85 of 100 examined time periods over a 26-year study period (1998–2023) covering pensions with nearly $4 trillion in combined assets under management, according to CEM Benchmarking data.
- • Long-term performance gap favors public real estate: REITs delivered 0.83% higher annual net total returns than private value-add/opportunistic funds from 1998 to 2023, and outperformed private core real estate by 1.75% annually, winning in 96 of 100 time periods examined.
- • Public and private real estate serve complementary portfolio roles rather than acting as rivals—private funds may offer long-term outperformance in select cases, while REITs provide liquidity, tactical flexibility, diversification across regions and property types, and steady income streams with lower management burden.
- • REITs address investor skepticism about volatility: While institutional investors historically favored private vehicles citing short-term price volatility and preferring appraisal-based returns, realized pension fund data demonstrates REITs' superior net-of-fees performance across market cycles.
- • Institutional investors benefit from hybrid allocation strategies that incorporate both asset classes—a well-selected portfolio combining private funds with REITs optimizes risk-adjusted returns while maintaining portfolio flexibility and reduced concentration risk.
Summary
Recent institutional research challenges the conventional wisdom that private real estate funds and REITs compete directly for investor capital. A comprehensive 26-year study by CEM Benchmarking, sponsored by Nareit and released in 2026, demonstrates that public and private real estate investments function more effectively as complementary portfolio components than as rivals. The analysis examined realized investment returns from pension funds managing nearly $4 trillion in combined assets from 1998 through 2023, providing a robust empirical foundation superior to simulation-based research previously cited in institutional debates.
The data reveals substantial performance advantages for REITs across nearly all market periods examined. REITs outperformed private value-add and opportunistic real estate investments in 85 of the 100 time periods studied, delivering an average annual net total return advantage of 0.83% over the full 26-year span. The performance differential widens when comparing REITs to private core real estate strategies: REITs achieved superior net returns in 96 of 100 periods examined, generating 1.75% higher annual returns on average since 1998. These results incorporate all fees and expenses, reflecting true investor experience rather than gross-of-fee performance.
Despite REITs' empirical performance edge, institutional investors have historically preferred private real estate vehicles, citing daily price volatility as the primary objection. Private funds' appraisal-based return reporting appears to smooth short-term fluctuations compared to REIT market pricing, creating a perception of lower risk that the CEM data does not support in realized returns. However, the research suggests this skepticism may be misplaced when evaluated through actual pension fund outcomes rather than price volatility metrics alone.
The complementary nature of both asset classes creates strategic value for diversified institutional portfolios. REITs offer liquidity, broad geographic and property-type diversification, lower operational overhead, and consistent income distributions—advantages particularly valuable for institutional allocators managing redemptions and rebalancing requirements. Well-selected private fund portfolios may provide concentrated return opportunities for investors with longer time horizons and higher risk tolerances, though historical net returns have not justified the liquidity constraints and fee structures relative to public alternatives. The optimal institutional approach incorporates both vehicles, using REITs for core real estate exposure and tactical positioning while deploying private capital strategically in value-add opportunities where manager skill can justify performance fees.
