Single-Tenant Net Lease (STNL) Commercial Real Estate Financing
Single-Tenant Net Lease (STNL) properties represent one of the most passive, predictable commercial real estate asset classes. Occupied by single corporate tenants under long-term absolute NNN leases, STNL assets command exceptionally aggressive long-term fixed-rate financing.
Key Financing Parameters & Standards

Remaining Lease Term10 to 20 years remaining lease duration required for optimal institutional pricing
Financing ExecutionNon-recourse CMBS, Life Insurance Company, or balance-sheet bank debt
* STNL loan terms depend almost entirely on tenant corporate credit ratings and remaining non-cancelable lease duration.
Why STNL Assets Are the Foundation of 1031 Tax Exchanges
For commercial real estate investors selling actively managed apartment complexes or shopping centers via a 1031 exchange, Single-Tenant Net Lease (STNL) properties offer the ultimate passive replacement strategy. The property is occupied by a single national corporate tenant operating under a 15 to 20-year absolute NNN lease.
The tenant pays rent on time every month while directly handling all real estate taxes, building insurance, parking maintenance, and structural roof repairs. The landlord simply collects "mailbox money" with zero day-to-day property management obligations.
Because the property has exactly one tenant, mortgage underwriting focuses far more on the tenant’s corporate balance sheet than on the physical real estate:
Corporate Parent Guaranty vs. Franchisee
Underwriters distinguish sharply between a lease backed by an investment-grade corporate parent (e.g., McDonald’s Corporate or Dollar General Corporation) versus a local franchisee LLC. Corporate-guaranteed leases command non-recourse, low-spread institutional debt, while franchisee leases require personal sponsor guarantees and higher interest rates.
Investment-grade credit (S&P BBB- or higher) unlocks optimal debt constants
Franchisee leases require unit-level store sales verification (health ratio <8%)
Corporate parent balance sheets are tracked continuously by credit rating agencies
Matching Loan Amortization to Lease Expiration
Institutional lenders require the remaining non-cancelable lease term to comfortably exceed the loan term. For a 10-year commercial mortgage, lenders prefer at least 12 to 15 years remaining on the initial lease. If a lease expires in year 7 of a 10-year loan, the lender faces binary dark-store risk, triggering mandatory cash sweeps.
Loan maturity must occur well before primary lease expiration
Early renewal options must be verified for unilateral tenant rights
CMBS vs. Life Company Financing for Net Lease Assets
Citizens Interstate places STNL debt across two primary institutional capital sources:
1. Life Insurance Companies: Provide low-leverage (50%–65% LTV), ultra-low fixed-rate financing with custom prepayment structures for high-credit corporate assets.
2. CMBS Capital Markets: Provide maximum leverage (up to 75% LTV) with 30-year amortization and full non-recourse execution, maximizing cash-on-cash equity returns.
Frequently Answered Questions
Common Questions About Single-Tenant Net Lease (STNL) Commercial Real Estate Financing
Direct, transparent answers regarding underwriting standards, documentation, and process.
Net Lease Debt
What is a Single-Tenant Net Lease (STNL) commercial loan?
Direct Answer
An STNL loan is commercial mortgage debt secured by a property occupied by a single corporate tenant under a long-term NNN lease, where loan sizing is driven primarily by the tenant’s corporate credit rating and remaining lease term.
Because the tenant covers all operating expenses and repairs, STNL loans carry low credit risk and qualify for aggressive fixed-rate financing.
Lease Duration
How much lease term is required to get a 10-year loan on an STNL building?
Direct Answer
Most institutional commercial lenders require at least 12 to 15 years of remaining lease term to approve a 10-year mortgage, ensuring the lease does not expire during the debt term.
If the lease expires within the loan term, lenders mandate aggressive amortization schedules or cash sweeps.
