NNN Lease Tenant Quality Analysis: How to Evaluate Credit and Reduce Default Risk

Triple-net (NNN) lease investing is often sold as the ultimate [passive income](/blog/real-estate-vs-stocks-2026) investment: a creditworthy national tenant signs a long-term lease, pays all expenses, and sends you a check every month. For the right tenant in the right deal, that's exactly what happens.

But NNN investors who don't rigorously analyze tenant credit quality have discovered the dark side: a struggling retailer closes its doors, and you're left with a vacant building purpose-built for a single tenant — with a long-term mortgage and no income.

This guide teaches you how to evaluate NNN tenant credit quality, understand the spectrum from investment-grade to speculative, and structure purchases that protect you against tenant default.

Why Tenant Credit Is Everything in NNN Investing

In a triple-net lease, the tenant is responsible for property taxes, insurance, and maintenance in addition to base rent. The landlord's return depends almost entirely on the tenant's ability and willingness to make lease payments for the full term — often 10–25 years.

Unlike multifamily investing, where a single vacant unit doesn't sink the investment, a [NNN property](/blog/triple-net-lease-investing) is typically single-tenant: if the tenant leaves, your income drops to zero instantly. This concentration risk makes credit analysis non-negotiable.

The quality of your tenant determines:

• The security of your income stream over the lease term
• The [cap rate](/blog/cap-rate-explained-for-beginners) the market assigns to your investment (lower cap rate = higher value)
• Your ability to refinance or sell the property
• The depth of the buyer pool when you exit

The Credit Spectrum: Investment Grade vs. Non-Investment Grade

Investment-Grade Tenants (BBB- and Above)

Tenants rated BBB- or better by S&P, Baa3 or better by Moody's are classified as "investment grade." These ratings indicate a low probability of default over a 10+ year horizon.

Examples of investment-grade NNN tenants (2026):

• Dollar General (BBB) — one of the largest NNN deal volumes in the market
• Dollar Tree/Family Dollar (BBB) — caution: some concern around Family Dollar closures
• Walgreens (B) — formerly investment grade, now below; a cautionary example
• CVS Health (BBB) — major pharmacy chain with strong credit metrics
• 7-Eleven (A- after strong acquisitions) — convenience store giant
• Starbucks (BBB+) — strong brand, global footprint
• McDonald's (corporate) (BBB+) — note: most McDonald's are franchisee-operated, not corporate

The cap rates on investment-grade NNN properties typically range from 4.5% to 6.5% depending on lease term remaining, location, and rent escalations.

Non-Investment Grade / Franchisee Tenants

Many national brands operate through franchise models. The tenant on your lease might not be McDonald's Corporation (BBB+) but rather "ABC Franchise LLC" — a franchisee with 15 locations and no public credit rating. This is fundamentally different risk.

How to analyze non-rated tenants:

1. Number of locations: A franchisee operating 50 locations is more financially stable than one with 3. More locations mean more revenue and diversification.
2. Years in operation: A 20-year franchisee with a strong track record is far less risky than a new operator.
3. Financial statements: Request 2–3 years of tenant financials. Look for positive EBITDA, manageable debt levels, and consistent revenue.
4. Operator reputation: Is this franchisee known in the local market? Ask the broker for background on the operating entity.

Corporate vs. Franchisee Guarantee

Even when the tenant is a well-known brand, confirm who is actually signing the lease guarantee:

• Corporate guarantee: The parent company (e.g., McDonald's Corporation) guarantees the lease. If the franchisee fails, the corporation must pay.
• Franchisee guarantee: Only the franchisee entity guarantees the lease. If the franchisee fails, the parent company has no obligation.
• Personal guarantee: The individual owner of the franchisee guarantees the lease. Provides some protection but limited by personal net worth.

Corporate-guaranteed leases command significantly lower cap rates (higher prices) because the risk is effectively transferred to the balance sheet of a large public company.

Reading a Tenant's Credit Profile

For Publicly Traded Tenants

Public companies file 10-K and 10-Q reports with the SEC, giving you access to audited financial statements, management discussion, and risk factors. Key metrics to review:

Revenue trends: Is total revenue growing, flat, or declining? A tenant with declining same-store sales has weakening fundamentals even if it's still paying rent today.

EBITDA margin: Healthy retailers typically maintain EBITDA margins of 8–15%. Shrinking margins indicate cost pressure that eventually threatens lease payments.

Debt-to-EBITDA: This is the most important leverage metric. A ratio below 3x is generally healthy; 4–5x warrants scrutiny; above 5x is concerning for long-term tenants.

Free [cash flow](/blog/net-operating-income-guide): Is the company generating positive free cash flow after capital expenditures? A retailer burning cash cannot maintain lease obligations indefinitely.

Credit rating and rating trajectory: Check current ratings on S&P Global, Moody's, or Fitch. More important than the current rating: has the rating been upgraded, downgraded, or placed on "negative outlook" recently? A Walgreens-style decline from investment grade to junk grade is precisely what NNN investors must anticipate.

The Walgreens Cautionary Tale

Walgreens was long considered the gold standard of NNN investing — corporate guarantee, strong credit, pharmacy recession-resistance. As recently as 2020, the company was rated investment grade.

By 2024–2025, Walgreens had been downgraded to non-investment grade (junk) status due to persistent pharmacy reimbursement headwinds, declining store traffic, and heavy debt. The company announced plans to close 1,200+ stores.

Investors who purchased Walgreens-tenanted NNN properties at 4.5% cap rates (based on their investment-grade status) faced a difficult choice: hold through the uncertainty or sell at higher cap rates (lower values). This episode illustrates why ongoing tenant monitoring is as important as initial due diligence.

Industry-Specific Risk Analysis

Beyond individual tenant credit, the industry your tenant operates in carries its own risks:

Dollar Stores (Dollar General, Dollar Tree)

• Positives: Recession-resistant, low price points attract customers across economic cycles, expanding store counts
• Risks: Family Dollar has struggled with operational challenges; potential regulatory risk from price point concerns; limited square footage means limited alternative use if vacated
• Location dependency: Rural and suburban locations outperform urban dollar stores

Quick Service Restaurants (QSR)

• Positives: Essential service, drive-through model resilient to e-commerce disruption
• Risks: Labor cost inflation squeezes franchisee margins; delivery app competition; food safety incidents
• Check: Is the lease corporate or franchisee? McDonald's corporate guarantee vs. a 5-location Burger King franchisee are very different risks.

Pharmacies and Healthcare

• Positives: Healthcare spending is largely recession-resistant; aging population drives demand
• Risks: Pharmacy reimbursement pressure from PBMs; Amazon/Walmart healthcare competition; store closures at struggling chains
• Watch: CVS has managed the transition better than Walgreens; specialty pharmacy and clinic-anchored locations are stronger

Auto-Related (AutoZone, O'Reilly, Advance Auto)

• Positives: E-commerce resistant (heavy parts, in-store expertise needed); older vehicle fleet extends service cycles
• Risks: EV adoption long-term; corporate-guaranteed NNN leases typically strong

Grocery-Anchored NNN

• Positives: Grocery is essential retail; strong foot traffic; anchor tenant anchors adjacent small-shop space
• Risks: Grocery chains face competition from Walmart, Amazon Fresh, Aldi; some regional grocers have thin margins

Lease Structure Details That Affect Risk

Beyond tenant credit, the lease structure itself determines your risk profile:

Absolute NNN vs. Modified Gross

Absolute NNN (Bondable Lease): Tenant is responsible for everything — roof, structure, HVAC, taxes, insurance, and all maintenance. Even if the building burns down, the tenant must continue paying rent or rebuild. Maximum protection for the landlord.

Modified Gross: Some expenses remain with the landlord (often structural elements like roof and foundation). Slightly more landlord responsibility but may attract stronger tenants who don't accept absolute NNN terms.

Always confirm whether "NNN" in the listing actually means absolute NNN — the term is used loosely.

Rent Escalations

A flat lease with no rent bumps loses purchasing power to inflation. Strong leases include:

• Annual fixed bumps (1–2%/year) — most common in dollar store and QSR leases
• CPI-linked escalations — rent increases with inflation, better inflation protection
• 10% bumps every 5 years — common in auto and pharmacy leases

Remaining Lease Term and Renewal Options

The value of a NNN lease diminishes as the primary term decreases. A lease with 3 years remaining is a very different investment than one with 15 years remaining — even with the same tenant.

Renewal options are at the tenant's discretion, not the landlord's. Don't count renewal option periods in your underwriting as assured income.

Practical benchmark: Most institutional buyers require minimum 10 years remaining on the primary term for full pricing. Sub-7 year leases trade at higher cap rates (lower prices) and attract a smaller buyer pool.

Building a Diversified NNN Portfolio

The purest risk management in NNN investing is diversification:

• Multiple tenants across different industries
• Multiple geographies (no single market concentration)
• Mix of corporate and strong franchisee guarantees
• Variety of lease term lengths (staggering expirations)

A portfolio of 8–10 NNN properties across retail, QSR, auto, and pharmacy sectors, spread across multiple states, provides income stability that a single-tenant investment cannot.

For investors building a NNN portfolio with financing, [[DSCR loans](/blog/best-dscr-lenders-2026)](/blog/dscr-loan-guide) are often the preferred product — underwritten on property income, not personal income, enabling rapid scaling.
