How do you finance buying a self-storage facility?

A real estate loan with an operating business inside

A storage facility earns rent on units let month to month, plus smaller streams: administration and late fees, tenant protection or insurance programs, boxes and locks sold at the counter, and commissions from a truck rental dealership where the facility has one. Expenses are light compared with most businesses: property taxes, insurance, utilities (heavier for climate-controlled units), repairs, marketing, software and a manager or two. What is left is net operating income, and it is that figure, not the operating company's goodwill, that carries the loan.

This is why a storage purchase is underwritten more like a property than like a service business. The lender orders an appraisal that values the facility on its income, reads the rent roll unit by unit, and checks the building, the land and the environmental record. The operating side still matters, because a facility run badly loses tenants and rent, but the collateral is real and the analysis starts from it. The SBA lending data for self-storage lessors shows how SBA lenders have financed the industry and how much of that lending funded changes of ownership.

SBA does not finance passive real estate investment, and a buyer should confirm early how the specific facility, and the entity that will own and run it, fits SBA's eligibility rules. Many SBA lenders and certified development companies finance self-storage as an operating business; the answer should be in hand before the letter of intent, not after. See eligible passive companies for how SBA separates the property-owning entity from the operating one.

The numbers a storage lender underwrites

The most common surprise is property tax. In many jurisdictions a sale resets the assessed value, so a facility bought at a price well above the seller's old assessment will carry a larger tax bill from the first year. Lenders underwrite the tax the buyer will pay, not the one on the seller's statements. The second adjustment is management: a seller who runs the facility personally often books no management expense at all, and lenders deduct a market fee regardless of who will do the work.

In plain numbers: a facility reporting net operating income of 500 might show 440 after taxes are restated at the purchase price, and 410 after a market management fee. Against loan payments of 340, that covers the debt above SBA's 1.15x minimum but below the 1.25x a bank or a change-of-ownership test under SOP 50 10 8.1 requires. The same purchase underwritten on the seller's figures would have looked comfortably covered.

Choosing the structure: 7(a), 504 or a commercial mortgage

A 7(a) suits a buyer who is paying for more than the property, such as goodwill, a management business or working capital, or who wants the lowest equity. A 504 suits a buyer paying mostly for real estate who wants a long fixed rate on much of the debt; whether a storage facility counts as special-purpose property, which raises the equity, is a question for the CDC. A conventional mortgage suits a stabilized facility with a strong buyer and a price the income supports. Some buyers use a 7(a) and a 504 together. The comparisons are in SBA 7(a) vs 504, SBA 504 vs a conventional mortgage and financing an acquisition with real estate; how SBA blends terms is in SBA blended maturity.

Lease-up and value-add facilities

Many storage buyers are paying for potential: a newer facility still filling, a property whose rents sit below the market, or land to add buildings. Lenders are cautious about all three for the same reason. The loan has to be repaid from income that exists, and SBA's change-of-ownership test under SOP 50 10 8.1 from 1 October 2026 is explicitly on historical results. A price that assumes the facility will be full, or that rents will rise, produces a gap between what the lender will lend and what the seller wants.

That gap is closed with more equity from the buyer, a seller note, or a lower price. A seller note on full standby for the life of an SBA loan can count for up to half of the required equity; a note paid currently is allowed but counts as debt. Expansion is financed separately, usually once the existing facility's results support it. See whether a lender will finance the full price and seller notes and SBA's full-standby rule. Purchases above what SBA can lend, or portfolios of several facilities, move to conventional lenders; see acquisitions above the SBA limit.

A storage lender lends on the rent roll the facility has, not the one the buyer plans to build.

What transfers, and what has to be rebuilt

• The property passes by deed, with title insurance, a survey and zoning confirmation. SBA lenders require an environmental review of the site, and conventional lenders commonly do the same.
• Tenant agreements are month to month and pass with the facility, along with deposits and prepaid rent, which should be credited to the buyer at closing.
• The management software and tenant data must move to the buyer's system without losing payment histories or autopay enrollments.
• A third-party manager or brand, if the facility uses one, is a contract that may end at the sale. The lender will want to know who manages the facility the day after closing.
• Truck rental and tenant protection programs are agreements with the seller and must be re-signed, or their income drops out.
• Lien-sale records. Auctions of units for unpaid rent follow state law. Lenders and buyers review how past sales were handled, since a mishandled sale is a liability that can follow the facility.

The risks lenders price

New supply is the risk lenders ask about first. A facility's rents can hold for years and then soften when a competitor opens nearby, so lenders look at the trade area, facilities under construction, and how the property compares on location, access and climate control. Next is condition: roofs, paving, doors, gates and security systems all wear, and deferred work becomes the buyer's cost. Lenders also look at how much of the income depends on raising existing tenants' rents, at insurance cost in regions exposed to storms or flooding, and at the flood zone itself, since federally backed loans require flood insurance on property in a designated flood hazard area. Boat and vehicle storage and outdoor parking are counted, but read as less stable than enclosed units.

Owner dependence, the risk that dominates most small-business purchases, matters less here. A storage facility can usually be run by a manager and good software. Even so, in an SBA-financed complete change of ownership the seller cannot stay on as an owner, officer or employee and may consult for up to 12 months, or up to 24 months under SOP 50 10 8.1 from 1 October 2026. Where the amount financed, less appraised real estate and equipment, exceeds $250,000, SBA also requires a business valuation; on a storage purchase most of the price is appraised real estate, so the part left to count can fall below that line; when it does not, or buyer and seller are related, the valuation is required and the loan for the purchase cannot exceed it.

What goes in the file

The SBA acquisition documents apply: the business tax returns for two to three years, the P&L and balance sheet, the latest full year of figures (never an older year), a year-to-date P&L, the debt schedule, the signed letter of intent, and each 20% owner's personal tax returns and personal financial statement. The full list is in what lenders need to finance an acquisition. For a storage facility, add:

• A current rent roll by unit: size, type, rent, move-in date and paid-through date.
• Monthly occupancy, both physical and economic, for at least two years, and a history of street rates.
• Trailing twelve months of operating statements, with ancillary income on separate lines.
• Delinquency reports and the lien-sale log.
• Property tax bills, and an estimate of the tax after reassessment at the purchase price.
• Capital spending history, the unit mix, site plan, and any management or program agreements.
