According to the Self-Storage Almanac, the US self-storage industry generated $44.3 billion in revenue in 2024 across 52,301 facilities. That is more locations than every Starbucks, McDonald's, Dunkin', Pizza Hut, and Wendy's in America combined. Most of them are run by people who hate spreadsheets.
That gap is the acquisition thesis.
The asset class in plain terms
Storage is boring on purpose. No inventory. No employees beyond a part-time manager. No receivables aging beyond 30 days before you can cut a lock and auction the unit. The business model is closer to a toll road than a retail operation.
That simplicity shows up in the margins. Self-storage runs at 70 to 110 percent gross profit margins and sustains 90-plus percent occupancy in undersupplied markets. TractIQ data from Q1 2026 shows REIT-operated occupancy at 87.7 percent nationally, with sophisticated operators tracking close behind at 81.8 percent. Household adoption has climbed from 8.95 percent in 2005 to 12.60 percent of US households in 2024, per the SSA 2025 Self Storage Demand Study.
These numbers explain why the asset class trades at 4.6x SDE — nearly two full turns above the all-industry small business median of 2.7x, per BizBuySell's Q1 2026 report.
What you pay
Cap rates govern the pricing conversation.
- Stabilized Class A, urban or climate-controlled: 5.5 to 6.5 percent cap rate, or 15 to 20x EBITDA
- Stabilized Class B/C: 6 to 8 percent cap rate, or 12 to 17x EBITDA
- Value-add and lease-up: 8 to 12 percent cap rate
A stabilized 400-unit facility typically runs $3M to $10M. Smaller 200-unit facilities in tertiary markets can trade around $1.2M. Class A multi-story builds in primary markets hit $12M to $35M for 600 to 1,000 units.
Budget 1.15 to 1.25x the purchase price for total capital required. Closing costs, working capital reserves, and near-term capex add up fast.
How it gets financed
SBA SOP 50 10 8, effective June 1, 2025, governs the terms for deals under $5M. Two loan structures work for storage acquisitions.
The SBA 7(a) handles the full stack: real estate, equipment, working capital, and closing costs in one loan. Buyer equity runs 10 to 15 percent of total project cost. Real estate amortizes over 25 years. The goodwill component amortizes over 10 years. Rate is typically Prime plus 2.5 to 3 percent, floating.
The SBA 504 is structured as two notes: a conventional bank first mortgage plus an SBA-backed second. It works better when the deal is predominantly real estate, which most storage acquisitions are. The blended rate is usually lower than a standalone 7(a). Equity injection runs around 10 percent.
Specialty lenders matter here. Live Oak Bank, BMO Harris Self Storage Lending, and First Western Trust offer purpose-built storage underwriting. They understand the rent roll and the occupancy curve in ways that generic commercial lenders do not. For deals over $5M, conventional CRE lending takes over.
The diligence failure point
Most storage acquisitions that go sideways fail at rent roll verification. Not at the letter of intent. Not at the financing. At the rent roll.
Here is the problem. A facility can show 92 percent physical occupancy, meaning 92 percent of units have something in them, while running 78 percent economic occupancy, meaning only 78 percent are paying at market rate. The gap sits in non-paying tenants pending lien sales, long-term discounts locked in years ago, and complimentary units given to the property manager.
That 14-point gap is the difference between the cash flow on the listing and the cash flow you collect.
Rent roll verification has three steps. First, confirm the physical-versus-economic occupancy spread. Second, compare in-place rents to current street rates. Many facilities hold below-market rates because the owner avoided the friction of raising them. Third, tie every line of the rent roll to actual bank deposits and management software reports, not the seller's summary spreadsheet.
Discount the seller's stated cash flow by 15 to 50 percent until each line is verified. Start there.
The second high-kill risk is tax reassessment. Most states reassess commercial property at the acquisition price. The seller's historical tax bill may be 40 to 60 percent of your post-close tax liability. Model the real number, not the historical one.
Third: insurance. Wildfire, hurricane, and flood exposure have driven premium increases of 40 to 80 percent in catastrophe-prone markets over the past three years. Get binding insurance quotes during diligence, before closing.
The value-add playbook
Storage acquisitions that win usually have one of five levers attached.
Rent rate management. Below-market in-place rents are the most common finding on acquisitions from owner-operators who avoid conflict. Systematic ECRI (existing-customer rate increases) and street-rate alignment can lift NOI 8 to 15 percent with zero capex.
Climate-control conversion. Adding climate-controlled inventory to a standard unit mix earns 30 to 60 percent rent premiums on converted units. NOI lift: 15 to 25 percent.
Adjacent land expansion. If the site has unused land or under-built square footage, the yield on incremental investment typically runs 9 to 12 percent. NOI lift: 30 to 60 percent.
Administrative space conversion. Excess office space, maintenance bays, and management suites often convert to revenue units. NOI lift: 3 to 8 percent.
Ancillary revenue. Tenant insurance programs, locks, moving supplies, and truck rental partnerships can add 5 to 10 percent to gross revenue without a single new unit.
Underwrite to current-state cap rates. Preserve the upside for yourself.
Who you compete against
Four REITs own roughly 25 percent of US inventory: Public Storage, Extra Space Storage, CubeSmart, and National Storage Affiliates. Their lower cost of capital compresses cap rates 100 to 150 basis points below private market pricing in primary markets.
You are not competing with REITs. You are finding deals they cannot or will not touch: secondary and tertiary markets, sub-$5M transactions, value-add theses with execution risk, and owner-operators who want to close in 60 days with someone who shows up.
Operator-buyers with verified experience and a clean SBA pre-approval win on speed. They often close before a REIT's acquisitions team has approved a term sheet.
For deals under $2M, skip the broker entirely. Direct outreach to owner-operators produces better pricing and cleaner deal processes. The broker channel covers 60 to 75 percent of deals above $2M, so build those relationships, but do not depend on them in the lower market.
The operator case
Levered returns for well-bought, well-operated storage facilities run 12 to 18 percent, per CT Acquisitions' 2026 analysis. Cash-on-cash return targets of 7 to 12 percent are achievable on deals where you close the rent-roll gap after acquisition.
That return is built on four things: buying at a fair multiple, financing 85 to 90 percent of the purchase price through SBA, closing the gap between in-place and street rates, and operating with a part-time manager and property management software rather than a full team.
The asset is not exciting. That is why it works.
Storage is one of the cleanest ETA targets in the lower middle market: real estate backing, durable demand, absentee-capable operations, and a fragmented seller base dominated by aging owner-operators ready to exit. The buyer who shows up with a verified rent roll review and an SBA term sheet often wins without an auction. At Patriot Growth Capital, that is exactly the kind of acquisition we pursue.

Frequently Asked Questions
How much does it cost to buy a storage facility?
A stabilized 400-unit facility typically runs $3M to $10M depending on climate-controlled mix, market tier, and facility age. Smaller 200-unit facilities in tertiary markets can trade around $1.2M. Budget 1.15 to 1.25x the purchase price for total capital including closing costs, working capital, and near-term capex.
Can I use an SBA loan to buy a storage facility?
Yes. SBA 7(a) and SBA 504 loans both work for storage acquisitions under $5M. Under SBA SOP 50 10 8, effective June 1, 2025, the minimum buyer equity injection is 10 percent of total project cost. Specialty lenders including Live Oak Bank and BMO Harris Self Storage Lending offer purpose-built underwriting for storage acquisitions.
What cap rate should I expect when buying a storage facility?
Stabilized Class B/C facilities trade at 6 to 8 percent cap rates in 2026. Class A urban or climate-controlled facilities run 5.5 to 6.5 percent. Value-add and lease-up properties trade at 8 to 12 percent cap rates to compensate for execution risk. Secondary and tertiary markets add 50 to 150 basis points above primary market pricing.
What is the biggest diligence risk when buying a storage facility?
The largest single risk is the gap between physical occupancy and economic occupancy. A facility showing 92 percent physical occupancy can run only 78 percent economic occupancy once you strip out non-paying tenants, below-market long-term discounts, and complimentary units. Verify the rent roll against actual bank deposits before accepting the seller's stated cash flow.
