The Real Risks of Single-Tenant Net Lease — and Their Prices

Net lease’s calm invites the assumption that risk left the building. It didn’t — it consolidated into a short list, each item priceable in advance. The taxonomy, with mitigations attached.

Binary vacancy

One tenant, one outcome at a time. Mitigate through basis discipline (the empty-building test before every offer), laddering several smaller deals instead of one large (the multi-property exchange exists for this), and corridor quality that guarantees a second act.

Credit migration

Guarantees are snapshots: Walgreens was a bond proxy in 2015; franchisee platforms restructure; private owners recapitalize. Mitigate by underwriting the store (its sales, its role in the network) alongside the parent, reading assignment clauses for how weak your counterparty could legally become, and pricing wider where transparency is thinner.

The re-lease cliff

Contract rent versus market rent at the lease’s end is the deferred question every single-purpose building carries — drugstore rents halve at re-tenanting; tunnel buildings barely convert. Mitigate with the arithmetic: divide contract rent by realistic replacement rent, and let deals above ~130% earn their premium some other way or pass.

Duration and rates

Long flat leases are bonds wearing brick: rising yields reprice them mechanically, as 2022-24 demonstrated to everyone holding 4-cap paper. Mitigate with escalations (annual bumps beat five-year steps beat flat), shorter-duration holds where your plan allows, and refusing to confuse today’s financing with forever’s.

Event risks

Casualty and insurance repricing, condemnation on highway corners, environmental legacies at fuel sites, municipal surprises. Each has a diligence ritual — casualty clauses, DOT project maps, Phase I history, zoning letters — that costs hundreds and covers millions.

The honest summary: NNN risk is legible, front-loaded, and mostly purchasable at the right basis. The investors who get hurt skipped the reading, not the luck.
