NNN REIT (NNN) Stock: Best Dividend Stock for Passive Income?

NNN REIT (NYSE: NNN) is one of the more established dividend-focused real estate investment trusts in the United States. Formerly known as National Retail Properties, the company owns thousands of retail properties leased primarily under long-term net lease agreements. For income investors, NNN stands out because of its exceptionally long dividend-growth record.

But in 2026, investors have a bigger question: Is NNN REIT one of the best stocks for passive income, or does its moderate growth and interest-rate sensitivity limit its appeal?

A Remarkably Consistent Dividend History

NNN's biggest attraction is its dividend track record.

In July 2026, the company raised its quarterly dividend to $0.62 per share, representing a 3.3% increase. This marked the company's 37th consecutive year of annual dividend increases. NNN is one of only three publicly traded REITs with at least 37 consecutive years of dividend growth. (NNN REIT |)

At the new quarterly rate, shareholders receive approximately $2.48 per share annually.

This consistency makes NNN particularly interesting for investors who prioritize reliable income over aggressive capital appreciation.

Strong Q2 2026 Results

NNN delivered solid second-quarter results.

Revenue increased to $244.3 million, compared with $226.8 million in the second quarter of 2025. More importantly for REIT investors, AFFO increased 5.9% year over year to $0.90 per share, while Core FFO increased 6% to $0.89 per share. (PR Newswire)

AFFO, or adjusted funds from operations, is particularly important because it provides a better indication of the cash available to support a REIT's dividend than conventional earnings.

The fact that AFFO per share is growing while the dividend continues to increase provides a positive foundation for the income thesis.

Nearly Full Occupancy

Another major strength is the quality and stability of NNN's property portfolio.

As of June 30, 2026, NNN owned 3,774 properties across all 50 U.S. states, with portfolio occupancy reaching 99.1%. The weighted average remaining lease term was approximately 10.1 years. (PR Newswire)

High occupancy reduces the risk of rental-income disruption.

Long lease terms also provide revenue visibility, although leases eventually need to be renewed and tenants can still experience financial difficulties.

For passive-income investors, predictable rental income is one of the most important characteristics of a net-lease REIT.

NNN Is Still Expanding

NNN is not simply maintaining its existing portfolio.

During the second quarter, the company invested $291 million in 89 properties at an initial cash cap rate of 7.3%. The weighted average lease term for those investments was 17.9 years. For the first six months of 2026, total investments reached approximately $436 million. (PR Newswire)

Management has now increased its 2026 acquisition-volume guidance to $700 million-$800 million, up from the previous $550 million-$650 million range. (PR Newswire)

Successful acquisitions can help NNN grow its rental base and support future AFFO and dividend growth.

2026 AFFO Guidance Was Raised

Management also increased its full-year outlook.

NNN now expects 2026 AFFO per share of $3.55-$3.59, compared with its previous range of $3.53-$3.59. Core FFO guidance was raised to $3.50-$3.54. (PR Newswire)

This is encouraging because dividend sustainability ultimately depends on cash generation.

Using the midpoint of the AFFO guidance, the $2.48 annual dividend represents a payout of roughly 70% of expected 2026 AFFO. That leaves some room for reinvestment, debt management, and future dividend increases.

What Makes NNN Different From a Traditional Stock?

REITs operate differently from most corporations.

Because they own income-producing real estate, investors often evaluate REITs using metrics such as FFO and AFFO rather than relying solely on GAAP earnings.

NNN's triple-net lease structure also shifts many property-level expenses to tenants. Tenants generally pay expenses such as property taxes, insurance, and maintenance under these arrangements.

This can create relatively predictable cash flows for the landlord.

For passive-income investors, that business model can be attractive because the company does not need to constantly sell products or services to generate revenue.

Interest Rates Are the Major Risk

NNN's biggest macroeconomic risk is interest rates.

REITs often rely on debt to finance acquisitions. When interest rates rise, borrowing becomes more expensive and the relative attractiveness of dividend-paying REITs can decline compared with bonds and other fixed-income investments.

As of June 30, 2026, NNN had approximately $5.1 billion of gross debt, with a weighted average interest rate of 4.2% and weighted average debt maturity of 10.1 years. The company reported $1.4 billion of available liquidity. (PR Newswire)

The long debt maturity profile provides some protection, but investors should still monitor refinancing costs and leverage.

Is NNN Stock Overvalued?

NNN traded around $45.73 on August 21, 2026, giving the company a market capitalization of approximately $8.85 billion. (NNN REIT |)

Based on the midpoint of management's 2026 AFFO guidance, the stock trades at roughly 12.8 times forward AFFO.

That is not an extremely expensive valuation for a high-quality net-lease REIT, although it also means investors should not expect explosive growth.

The primary attraction is the combination of income, stability, and gradual dividend growth.

Could NNN Be the Best Dividend Stock for Passive Income?

NNN has many characteristics income investors want:

• A 37-year dividend-growth streak

• Approximately 99% portfolio occupancy

• Thousands of diversified properties

• Long-term leases

• Growing AFFO

• Increasing acquisition activity

• A strong liquidity position

• A dividend yield around 5% at recent prices (NNN REIT |)

However, "best" depends on the investor.

Someone seeking maximum dividend yield may find higher-yielding REITs. An investor seeking rapid capital appreciation may prefer faster-growing companies.

NNN's appeal is consistency.

Final Verdict

NNN REIT is one of the more attractive dividend stocks for investors focused on long-term passive income, but it should not be viewed as a risk-free investment.

Its 37-year dividend-growth record, 99.1% occupancy, long lease duration, growing AFFO, and disciplined acquisition strategy create a strong income-investment foundation. (NNN REIT |)

The biggest risks are interest rates, leverage, tenant credit problems, and slower-than-expected acquisition growth. Investors should also remember that REIT dividends can fluctuate and stock prices can fall even when the dividend remains stable.

Bottom line: NNN may not deliver spectacular growth, but its combination of roughly 5% income, decades of dividend increases, high occupancy, and relatively predictable rental cash flow makes it a compelling candidate for a long-term passive-income portfolio.

For investors building an income-focused portfolio, NNN deserves a place on the watchlist—particularly when its valuation becomes more attractive relative to its historical range.
