Two Leading Top REITs Face Off: Realty Income vs. NNN REIT Showdown

When it comes to dividend investing, top REITs stand out as compelling options for income-focused investors. The structure of real estate investment trusts mandates distribution of at least 90% of taxable income to shareholders, making them attractive for those seeking steady cash flow. Among the diverse landscape of top REITs specializing in retail properties, Realty Income (NYSE: O) and NNN REIT (NYSE: NNN) have emerged as particularly strong performers, each commanding thousands of retail properties across their portfolios.

The narrative around retail REITs has shifted dramatically. What once seemed like existential threats—the e-commerce revolution and the subsequent interest rate hikes of 2022-2023—have proven far less damaging than feared. Through the first nine months of 2025, retail-focused REITs delivered an average return of 6.9%, according to the National Association of Real Estate Investment Trusts. Yet these two top REITs approach their market dominance differently, and understanding those distinctions matters for investors trying to decide which aligns better with their financial goals.

Realty Income: The Heavyweight Champion of Top REITs

With over 15,540 properties in its portfolio, Realty Income represents one of the most established players among top REITs. The company draws roughly 80% of rental income from retail properties, with grocery stores and convenience stores forming the backbone at approximately 21% of total revenue. The roster of blue-chip tenants—Dollar General, Walgreens, Home Depot, and Walmart—underscores the quality of its tenant base.

The numbers tell an impressive story. Realty Income maintains a 98.7% occupancy rate and successfully renewed leases at 3.5% higher rates, demonstrating tenant quality and pricing power. Its adjusted funds from operations (AFFO)—the metric that matters most for REIT investors—increased 2.9% year-over-year to $1.09 per diluted share. The company’s dividend tells an even more compelling tale: a 33-year streak of annual increases, with the latest bump moving the monthly payout from $0.269 to $0.2695 per share. Projected AFFO of $4.25 to $4.27 per share easily supports the annualized dividend of $3.23.

The dividend yield sits at 5.7%, rewarding patient shareholders consistently. Yet size presents a double-edged sword. Adding meaningful new properties to a 15,000-plus portfolio simply doesn’t move growth metrics substantially. Investors in this top REIT must embrace steady, measured expansion rather than explosive gains.

NNN REIT: The Nimbler Challenger

With approximately 3,700 properties, NNN REIT operates in a fundamentally different category among top REITs. Its smaller footprint actually becomes an advantage, allowing each new property acquisition to meaningfully impact growth metrics. The portfolio spans diverse retail categories—convenience stores, automotive services, restaurants, and family entertainment venues—providing meaningful diversification within its more focused geographic scope.

Management’s stewardship shows in the occupancy metrics: 97.5% in the third quarter reflects consistent tenant quality and lease performance. Quarterly AFFO per share climbed from $0.84 to $0.86, while the company extended its dividend increase streak to 36 years with an August boost of 3.4% to $0.60 per share. With projected AFFO guidance of $3.41 to $3.45 per share, coverage remains robust.

The dividend yield of 5.9% edges slightly higher than Realty Income’s, though the real distinction lies elsewhere. NNN REIT’s relative youth and smaller scale mean that property investments still substantially move the needle on growth projections—a luxury unavailable to its mega-sized competitor.

Evaluating Top REITs: Which Deserves Your Capital?

Both companies have proven their mettle in a challenging retail environment by investing strategically in recession-resistant retail categories. Groceries, pharmacies, automotive services, and dollar stores all demonstrate resilience across economic cycles. Their three-decade-plus dividend increase streaks showcase commitment to shareholder returns through thick and thin.

The fundamental trade-off becomes clear: Realty Income offers the security and stability of an established mega-cap REIT with proven tenant diversification. NNN REIT counters with growth flexibility and higher dividend yield, though with less portfolio diversification. For investors prioritizing steady, predictable income from top REITs, Realty Income delivers. For those comfortable with more narrowly focused U.S. retail exposure and seeking greater expansion potential, NNN REIT presents the more compelling opportunity. The choice ultimately hinges on whether you value Realty Income’s fortress-like stability or prefer NNN REIT’s nimbler growth trajectory among top REITs competing for your investment dollars.
