Self-storage has a reputation as a simple business: build boxes, rent boxes, collect rent. Anyone who has run a facility knows better. Revenue depends on pricing discipline, collections, marketing, software and process. That’s why self-storage diligence should look more like buying a small operating business than buying a building.
This checklist comes from our experience owning and operating storage facilities, not just selling them.
1. Occupancy: three ways
- Physical occupancy: units occupied ÷ total units.
- Square-foot occupancy: rented square feet ÷ rentable square feet.
- Economic occupancy: actual collected revenue ÷ potential revenue at street rates.
A facility can be 90% physically occupied and far lower economically if rates are stale or delinquency is high.
2. Street rates vs. in-place rates
Compare what new customers pay (street rates) with what existing tenants pay (in-place). Many independent owners rarely raise existing customer rates, creating a gap a disciplined buyer can close over time with careful rate management.
3. Delinquency and collections
Request delinquency aging reports (0–30, 31–60, 61–90, 90+ days). High delinquency can signal weak process, a difficult customer base or inflated occupancy.
4. Lien and auction history
Texas self-storage liens and sales are governed by Chapter 59 of the Texas Property Code. Review how the seller handles notices, lien sales and documentation. Read Texas self-storage lien law basics.
5. Software data, not seller summaries
Ask for exports directly from the management software: rent roll, unit mix, move-ins/move-outs, rate change history, delinquency and ancillary revenue. Reconcile to bank deposits.
6. Unit mix and demand
Compare the unit mix to local demand. Too many large drive-up units in an apartment-heavy area or too few climate-controlled units in a high-income area can limit performance.
7. Supply pipeline
Map competing facilities within a three- and five-mile radius, including those under construction or permitted. New supply nearby can pressure rates for years.
8. Physical condition
Roofs, doors, gates, keypads, cameras, lighting, paving, drainage, climate-control systems and office condition. Many older Texas facilities need roof and paving work.
9. Expansion potential
Excess land, deed restrictions, utility capacity and detention requirements determine whether you can add units later.
10. Taxes and insurance
Property taxes may be reassessed after sale. Insurance costs on the Gulf Coast have risen. Model both conservatively.
Frequently asked questions
What occupancy should a self-storage facility have?
Stabilized facilities often run high physical occupancy, but economic occupancy and rates matter more.
What documents should I request when buying storage?
Software exports for rent roll, unit mix, delinquency, move-ins and move-outs, rate history and financial statements reconciled to bank deposits.
Is self-storage a good investment in Houston?
It can be in trade areas with growing population and limited new supply. Underwriting the specific trade area is critical.
