Expense recoveries: the lever most flex owners leave on the table.

In small-bay industrial flex, the returns are made after the purchase — in operations. And the single most overlooked operating lever is expense recovery.

Most small-bay parks were built and held by the families who developed them, often decades ago. They are wonderful assets run with informal leases: gross or modified-gross structures, inconsistent CAM (common area maintenance) pass-throughs, taxes and insurance partially absorbed by the owner, and renewals handled on a handshake. None of that is a knock on the prior owner — it's how a side-project gets run. But it leaves real net operating income sitting on the table.

The fix isn't raising face rents; it's structuring the lease so the tenant pays their proper share of the operating costs they generate. Converting suites to a true triple-net (NNN) basis at renewal — recovering taxes, insurance, and CAM — can lift NOI meaningfully without changing the headline rent a tenant quotes their accountant. Two things make this work in flex specifically. First, tenants are sticky: roughly 85% renew at term, because the suite is mission-critical to their business and the rent is a rounding error on their P&L. Second, you control the renewal calendar, so you can correct under-recovery building by building as leases roll, rather than fighting a single hard reset.

Stack that on top of marking in-place rents to market at renewal and investing selectively in capex that supports pricing or retention, and the math compounds. A few hundred basis points of recovered expense here, a mark-to-market bump there, repeated across a portfolio of suites, is the difference between a building that drifts and one that compounds. It's unglamorous work — reading leases, re-papering recoveries, holding the line at renewal — which is exactly why so much of it goes undone, and why it remains one of the most dependable sources of value-add in the asset class.
