NNN Lease Financing: Complete Guide to Tenant-Credit-Driven CRE Debt

Why Tenant Credit Drives Everything

Standard commercial real estate financing underwrites the property's cash flow at-large, multiple tenants, lease diversification, market rent assumptions, vacancy reserves. NNN single-tenant financing flips this: there's ONE tenant generating ALL the property's cash flow. If that tenant defaults or leaves, the property has no income.

Lenders respond by underwriting the TENANT'S credit, not the property. A Walgreens-occupied 13,500 SF building isn't priced based on what the building is worth, it is priced on the tenant credit, the remaining lease term and the contractual rent. Walgreens lost its public ratings in August 2025 when the company was taken private, so lenders now underwrite store level performance instead. Dollar General is still rated BBB by S&P.

NNN deals price along the public credit spectrum as of 26 August 2026. Walmart is AA. Target is A. JPMorgan parent is A and the bank entity is AA minus. 7 Eleven Inc. is A minus. Walgreens no longer carries a public rating. Franchisees and unrated regional chains price wider or go specialty. PeerSense sources capital through a curated network of commercial lenders and capital sources.

The practical implication: when underwriting an NNN purchase, get the tenant's most recent S&P/Moody's credit rating before going to LOI. The rating tells you 80% of what your financing will look like.

The Major NNN Tenants and Their Rate Profiles

Five tenants dominate U.S. credit tenant NNN financing. Credit as of 26 August 2026. Re-check 24 November 2026.

Walgreens (unrated): About 13,500 SF prototype, $3M to $15M typical deal size. Unrated since 28 August 2025. Boulder Group Q2 2026 asking cap 8.10 percent. Closed trades about 7.50 to 9.50 percent. Leverage 55 to 65. Pre screen against the Walgreens closure list before LOI.

CVS (BBB / S&P, Baa3 Moody's): About 13,000 SF prototype, $3M to $15M typical. BBB from S&P as of May 2026. Moody's Baa3 as of 7 August 2026. It is not A minus. Boulder Group Q2 2026 asking cap 6.85 percent.

Dollar General (BBB / S&P, Baa3 Moody's): About 9,400 SF prototype, $1M to $2.5M typical. BBB from S&P as of 10 September 2025. It is not BBB minus. Common small 1031 exchange target.

Starbucks (BBB+ / S&P, Baa1 Moody's): About 2,500 SF drive thru prototype, $2M to $8M typical. BBB+ from S&P as of 5 May 2026. 10 year base lease, shorter than the drugstore standard.

7 Eleven Inc. (A minus / S&P, Baa2 Moody's): About 2,800 SF convenience prototype, $3M to $10M typical. Parent Seven and i is A minus from S&P and A3 from Moody's, both cut in 2025. Not a naked A.

How Lease Term Affects Pricing

After tenant credit, the second-most-important pricing variable is REMAINING LEASE TERM. CMBS conduits underwrite 10-year terms; if the tenant lease ends before the loan matures, that's a re-leasing risk the lender prices into the spread.

Fresh 25-year lease (just signed): Tightest pricing. Tenant has 25 years remaining; lender's 10-year CMBS is fully covered by the lease term + 15-year cushion. No re-leasing risk during loan term.

Mid-term lease (10-15 years remaining): Standard pricing. Lease covers the 10-year CMBS term with reasonable cushion.

Short-term lease (5-10 years remaining): Wider pricing. Lender models re-leasing risk if tenant doesn't renew. Some CMBS conduits require minimum 10 years remaining; below that, deal goes to specialty lenders or smaller-loan programs.

Very short (<5 years): Materially wider pricing or lender decline. Re-leasing risk dominates the underwriting. Bridge financing often makes more sense than long-term CMBS for this profile.

Practical implication: if a tenant just exercised a renewal option (extending the lease 5+ years), the property typically gets a tighter CMBS spread on refinance vs. its prior structure. This is a common value-creation move for NNN owners, wait for tenant renewal, then refinance into longer-term, lower-rate CMBS.

1031 Exchange Mechanics with NNN

Most NNN buyers are 1031 exchange buyers, investors selling appreciated property and rolling proceeds into NNN replacement to defer capital gains tax. The 1031 timeline creates specific NNN purchase dynamics:

Day 0: Sell relinquished property. Proceeds go to qualified intermediary (QI), not directly to seller (preserves tax-deferred status).

Day 0-45: Identification window. Identify up to 3 replacement properties (or 200% of relinquished value with no count limit) in writing to QI.

Day 0-180: Exchange window. Close on identified replacement(s) within 180 days of original sale.

NNN's 1031 fit: Standard CMBS NNN closes in 45-75 days. Comfortable inside 180-day window if started during identification phase. Coordinate rate lock with QI's distribution schedule + CMBS conduit's securitization timeline.

Tenant selection for 1031: Buyers typically prioritize: (a) familiar tenant with public credit rating (Walgreens, CVS, Dollar General most common), (b) deal size matching exchange balance ($1-3M for Dollar General, $3-15M for drugstore, $5-25M for portfolio), (c) clean property condition (no Phase II environmental issues), (d) freshly-extended or long-remaining lease.

Common 1031 trap: Identifying property with environmental concerns or short remaining lease term. Closing fails inside 180 days; exchange fails; capital gains tax applies. Pre-screen identification candidates carefully, NNN deal that looks perfect at LOI may have lender-killing issues at full diligence.

Ground Lease NNN Structures

Some NNN deals are NOT fee-simple, the operator owns the BUILDING on land owned by a separate party (typically a long-term ground lessor). This is the dominant McDonald's structure historically.

Leasehold mortgage: The lender takes a security interest in the leasehold (the operator's right to use the land + the building). Structurally similar to a mortgage but on the leasehold interest rather than fee-simple ownership.

SNDA agreement (Subordination, Non-Disturbance, Attornment): Required from the ground lessor. The SNDA confirms: (a) ground lessor's lease subordinates to the leasehold mortgage in default, (b) ground lessor won't disturb the lender's collateral if operator defaults, (c) ground lessor will accept lender (or lender's foreclosure purchaser) as new tenant if operator is foreclosed.

Without SNDA, the deal doesn't close. Lenders will not take leasehold mortgage risk without ground lessor consent. SNDA negotiation can take 30-60 days, start early in diligence.

Pricing: Leasehold NNN typically prices 50-100 bps wider than fee-simple NNN at equivalent tenant credit + lease term. Reflects lender administrative complexity + ground lease term risk.

Common ground lease structures: McDonald's typically owns the land + leases to franchisee operating company. Some Walgreens / CVS deals have similar structure where REIT owns land and operator owns building. Verify the specific structure during LOI; don't assume fee-simple.
