Empirical Analysis & Findings

## Single-Tenant Net Lease (STNL) Capitalization Rate Mechanics

Triple Net (NNN) properties represent pure fixed-income proxies in commercial real estate. Because the tenant absorbs real estate taxes, insurance, and maintenance, Net Operating Income (NOI) equals gross base rent.

### 1. Capitalization Rate Pricing Formula

$$\text{Property Value} = \frac{\text{Net Operating Income (NOI)}}{\text{Market Capitalization Rate}}$$

Where:
$$\text{Cap Rate} = \text{Risk-Free 10-Year Treasury Yield} + \text{Tenant Credit Risk Spread} + \text{Illiquidity Premium}$$

| Tenant Class | Representative Credit Rating | Average 2026 Cap Rate | Typical Lease Term |
|:-------------|:----------------------------:|:---------------------:|:------------------:|
| Pharmacy (Walgreens/CVS) | BBB / BBB- | 5.85% - 6.40% | 15 - 20 Years |
| Dollar Stores (Dollar Gen) | BBB | 6.20% - 6.75% | 15 Years |
| Fast Food (QSR Corporate) | A / A- | 5.10% - 5.60% | 20 Years |
| Industrial Logistics NNN | A- / Unrated | 5.40% - 6.25% | 10 - 15 Years |

Frequently Asked Questions

What is a Triple Net (NNN) lease in commercial real estate?

In a NNN lease, the tenant is responsible for paying base rent plus all property operating expenses: real estate taxes, building insurance, and structural maintenance.

How does tenant credit rating impact capitalization rates on NNN properties?

Properties leased to investment-grade tenants (BBB+ or higher, e.g. Walgreens or Dollar General) trade at 100 to 250 basis points lower cap rates than unrated private tenants.
