Evaluating Tenant Credit Quality: Investment Grade, National Non-Rated, and What They Mean
A NNN lease is a contractual promise to pay rent for a defined period. Like all financial promises, its value depends entirely on the ability and willingness of the promisor to honour it. An investment-grade credit rating from S&P (BBB- or above) or Moody’s (Baa3 or above) represents an independent third-party assessment that the entity making the promise has the financial strength to do so over the medium term — even through economic stress.
The practical investment consequence of this distinction is significant. When McDonald’s Corporation signs a 20-year NNN lease at $150,000 per year, investors are buying 20 years of McDonald’s corporate cash flows — backstopped by the financial resources of one of the world’s most valuable brands. When a local restaurant operator signs the same lease, investors are buying 20 years of that single business’s cash flows — backstopped by the resources of a single operator.

| Lease Enforcement Risk | Very low — corporate balance sheet | Moderate | High — personal guarantee may be insufficient |
