A self storage flyer that leads with a stabilized occupancy percentage is telling you the least useful number in the package. It says nothing about unit mix, nothing about how much of that occupancy sits in the climate-controlled units that actually carry the rent premium, and nothing about the competing facility that broke ground two exits down the road.
Stabilized Occupancy Hides The Unit Mix
A facility can show ninety percent occupancy while its ten-by-thirty drive-up units sit half empty and its five-by-five climate-controlled units are the only thing carrying the number. We ask for occupancy broken out by unit size and by climate-controlled versus drive-up, because a headline occupancy figure built on the smallest, cheapest units is a very different income story than one built on the units that actually generate the premium rent.
Vehicle and boat storage bays deserve the same scrutiny, since a facility that counts a handful of oversized parking spaces toward its overall square footage can show a healthy blended rate per square foot that does not reflect what the standard indoor units are actually achieving. We separate outdoor parking and vehicle storage income from indoor climate-controlled and drive-up unit income specifically, because blending the two into one average rate per square foot can make a facility look stronger than its core self storage income actually supports.
Growth Corridors Around Arlington, Lakeland, And Collierville
New rooftops in Arlington, Lakeland, and Collierville have pulled self storage demand outward from the older core facilities closer to the city. That growth is real, but it also means new competing facilities keep entering these same submarkets, and a trade-area analysis that does not account for supply already under construction nearby is measuring demand against yesterday's competitive set.
Counting Competitors The Flyer Forgot To Mention
We map every competing facility within the trade area ourselves rather than relying on the seller's competitive summary, because a seller has every incentive to leave out a new facility that just opened with an introductory rate promotion. A facility candidate near Southaven or Olive Branch, for example, needs its Mississippi-side competitive set checked separately, since demand can pull from either side of the state line depending on which access roads serve the trade area.
We also track how long any nearby competing facility has been offering promotional rates, since a brand-new facility running an aggressive introductory discount for its first year of lease-up behaves differently than an established competitor permanently discounting to compete on price. A trade area with two facilities both discounting heavily suggests genuine oversupply pressure, while a single new entrant running a temporary lease-up promotion is a different and often temporary competitive dynamic that should be modeled accordingly rather than treated as a permanent ceiling on achievable rent.
Rate Growth Versus Rate Discounting To Fill Vacancy
Self storage income can look like it is growing when in-place rents are rising while the facility is quietly offering first-month-free promotions to new tenants to keep occupancy up. We check the actual net effective rent after promotions, not the posted rate, because a rent roll built on posted rates alone can overstate durable income by a meaningful margin.
We also check how long the average tenant actually stays once the promotional period ends, since a facility that fills units cheaply but loses those same tenants within a few months is not building the kind of durable occupancy an exchange investor should rely on. A trailing tenant retention figure tells a very different story than a snapshot occupancy percentage taken on a single date.
What The Self Storage File Documents Before Identification
A self storage candidate earns a place on the identification list once the file shows:
- Occupancy broken out by unit size and by climate-controlled versus drive-up
- A trade-area competitor map that includes facilities under construction, not only open ones
- Net effective rent after promotions, not only the posted rate card
- Access and visibility confirmed against the specific corridor, since storage demand is highly access-dependent
- Management structure, since third-party managed facilities and owner-operated facilities carry different expense assumptions
Common 1031 Exchange Questions
Why does unit mix matter more than overall occupancy for self storage?
Because a high overall occupancy figure can be driven by the smallest, lowest-rent units while premium climate-controlled space sits underused. We break out occupancy by unit type before treating a headline number as meaningful.
How fast is new self storage supply growing around Arlington and Lakeland?
New rooftops in these corridors have drawn additional storage development in recent years, which means a trade-area analysis needs to account for facilities under construction, not only the currently open competitive set, before relying on demand projections.
Does a promotional rate distort the rent roll?
Yes. A facility offering first-month-free or discounted introductory rates can show rising posted rents while net effective rent stays flat or declines. We check net effective rent after promotions rather than trusting the rate card alone.
Should DeSoto County storage facilities be compared against Memphis facilities directly?
Not without checking which side of the state line actually feeds the trade area. Southaven and Olive Branch facilities can draw from either Tennessee or Mississippi depending on access roads, so the competitive set needs its own mapping rather than borrowing Memphis assumptions.
Does third-party management change how a self storage candidate should be underwritten?
Yes. Third-party managed facilities typically carry a management fee and standardized reporting, while owner-operated facilities can have inconsistent recordkeeping. We confirm which structure is in place before relying on the expense history provided.
