On the rent roll, the anchor looks like the safest line: the biggest space, often the strongest credit, frequently the longest lease. The rent roll is not lying, but it is only telling half the story, because the anchor's real role in a strip center is not its own rent. It is the traffic that makes every other rent in the center possible, and that second role is where the risk lives.
The mechanism that converts anchor risk into center risk is written into the inline leases themselves. Co-tenancy clauses give smaller tenants remedies if the anchor goes dark: rent reductions, a switch to percentage rent, sometimes termination rights. Which means one departure is not a twelve or fifteen percent income event, whatever the anchor's share of the rent roll says. It is that, plus a contractual chain reaction across the tenants who stayed, and the chain reaction is not speculative. It is sitting in the lease files right now, waiting to be read, and reading every inline lease for its co-tenancy language is not diligence trivia. It is the underwriting.
Two distinctions sharpen the analysis. Credit versus draw: an anchor can be investment-grade and still fading as a traffic generator, and the inline tenants live on the traffic, not the credit rating. The healthiest situation is an anchor whose parking lot answers the question before the financials do. And dark versus gone: some anchors keep paying rent on a store they have closed, which protects your income statement while it quietly starves the inline tenants who depended on the foot traffic. A paying dark anchor is a slow-motion version of the same problem, and underwriting that treats rent received as risk resolved will miss it.
So the anchor scenario belongs in the stress test, run honestly: the anchor leaves, the co-tenancy provisions fire as written, downtime on a big box runs long because the pool of replacement users is short, and the backfill likely signs at a different rent with a real TI package. What does coverage look like in that year? What does the exit look like if it happens late in the hold? A center that survives its anchor scenario is a different asset than one that does not, and the two should not be priced the same, however similar their rent rolls look at a glance.
This is exactly the kind of joint, contractual, timing-dependent scenario that blanket assumptions cannot see and per-tenant modeling exists for. PropCalc™ lets the anchor carry its own rollover assumptions and lets the stress grid show what the departure year does to the whole deal, coverage included. The anchor is the hero of the rent roll right up until it is the whole problem. Underwrite both versions.
