Single-tenant triple net (NNN) properties occupied by investment-grade tenants are attractive commercial real estate investments because they produce predictable income with minimal management burden. The landlord receives base rent while the tenant covers property taxes, insurance, and maintenance. Understanding how to finance them helps MLOs serve commercial investors who are entering or expanding in this asset class.
What Triple Net Means
In a triple net lease, the tenant pays base rent plus the three nets: property taxes, building insurance, and maintenance costs. The landlord's income is highly predictable because their net operating income is essentially the base rent, with minimal variable expenses on their side of the ledger. The quality of the income stream depends almost entirely on the credit quality and remaining lease term of the tenant.
How Lenders Underwrite NNN Loans
Lender appetite for NNN financing depends primarily on three factors: tenant credit rating, remaining lease term, and property location. Investment-grade tenants (national pharmacy chains, major fast food franchisors, dollar stores, credit-rated grocery chains) command the most favorable financing terms. Lenders want the remaining lease term to extend well beyond the loan maturity date, often by at least 5 years. Non-rated franchisees and local tenants receive much tighter terms.
- ✦LTV: typically 65-75% for investment-grade NNN; may reach 80% for highest-credit tenants with long leases
- ✦DSCR: minimum 1.20x to 1.25x in most commercial programs
- ✦CMBS: commonly used for NNN investment loans; provides non-recourse structure above certain loan sizes
- ✦Dark value: lenders assess what the property is worth without the tenant; single-purpose buildings carry more risk
Loan Structures That Fit NNN
CMBS is the most common structure for larger NNN loans because the predictable, creditworthy income stream packages well into securitized pools. Portfolio lenders (banks and credit unions) originate smaller NNN loans with recourse. SBA financing is not applicable unless the investor is also the tenant-operator. NNN cap rates have compressed in recent years for top-tier tenants, meaning buyers need debt that matches the income yield.
