How to Value a Self-Storage Facility in Illinois

Self-storage facilities in Illinois blend real estate investment with operating business characteristics, making them a distinct asset class. Well-occupied facilities typically trade at cap rates of 5–7% based on Net Operating Income (NOI), or 10x–15x EBITDA for smaller owner-operated facilities. Values are heavily location and occupancy-driven.

Occupancy and Rate Trends

A storage facility running at 90%+ physical occupancy for 12+ months is in strong position to support a premium valuation. Buyers examine revenue per square foot, unit mix (climate-controlled vs. drive-up), and rate trends over time. Consistent rate increases achieved without significant unit vacancy demonstrate pricing power that supports higher multiples.

Self-Managed vs. Third-Party Management

Facilities using professional management software with automated billing, online reservations, and electronic gate access are far more attractive to institutional buyers than cash-based, manual-management operations. Technology investment is a genuine value driver. Facilities managed through national operators (Extra Space, Public Storage) under a management agreement may have ROFR provisions to address.

Illinois self-storage markets — particularly suburban Chicago, Rockford, and Peoria corridors — have attracted significant investment capital. Even small facilities of 200–400 units can attract competitive bids from regional investors.

How Illinois buyers put a number on how to value a self-storage facility

This page is the valuation guide. It is not the sale-process playbook. Seller’s discretionary earnings (SDE) is the cash a full-time working owner can take after you normalize the books. Start with the tax return. Add owner pay and one-time costs. Subtract the wage you must pay to replace the owner.

Self-storage buyers underwrite NOI / EBITDA after a market-rate manager, not SDE that still includes the owner living on site. Occupancy, street rates, and climate-control mix are the recast. Late-fee spikes and tenant-insurance commissions need their own lines. A 5x–8x band is planning language aligned with the site’s NOI range — it is not an appraisal of the dirt.

Planning band on this vertical: 5x–8x SDE. That is a range, not a quote. BizBuySell’s Q2 2026 Insight Report showed a 2.7× cash-flow multiple across all reported closed deals. Do not use that marketplace average as this shop’s appraisal.

A worked planning example (illustration)

Illustration only — not a quote for any Illinois shop. A storage facilitie whose tax return shows $311,000 of net profit is not worth $311,000 × a rumor multiple.

Add back the owner’s $183,000 W-2 and payroll tax, $12,000 of discretionary benefits, $500 of accepted one-time cost, and $4,000 of personal expenses that a buyer will not run. Then subtract $25,000 of replacement labor if the owner still diagnoses, sells, or closes the books.

Adjusted SDE in this illustration is $485,000. At 6.50x, enterprise value is $3,152,500 before debt, working capital, holdback, and tax.

SDE line items buyers actually use

1. Reported net profit (tax return, not the marketing P&L)
2. + Interest expense
3. + Income taxes (not payroll, sales, or property tax)
4. + Depreciation and amortization
5. + Owner W-2, bonuses, and payroll taxes on the owner
6. + Discretionary owner benefits that a buyer will not keep (auto, personal travel, family on payroll with no role)
7. + Accepted one-time or non-recurring expenses
8. − Market-rate replacement labor for owner work that will not transfer
9. = Seller’s Discretionary Earnings (SDE)

What moves the multiple up or down

• Occupancy and in-place rates versus street
• Climate-control mix and capex condition
• A manager model that is not the seller in the apartment
• Clean Illinois lien-and-auction file
• Trade-area supply that a REIT will not immediately discount

What does not transfer with the price

Zoning, fire code, and municipal business licenses are the live items. The Illinois Self-Service Storage Facility Act governs liens, notices, and auctions — a buyer inherits that compliance culture. There is no statewide “storage operator license,” but a change of ownership that bungles lien notices creates liability. Climate-control and fire-suppression inspections sit with the premises.

Diligence that changes the number

• Occupancy, street vs in-place rates, and unit-mix (climate vs drive-up)
• Manager model: on-site, remote, or third-party
• Lien-notice and auction-file discipline under Illinois law
• Real estate, debt, and whether this is an entity sale or a property sale
• Deferred capex: roofs, doors, cameras, access control
• Competitive new supply inside the trade area

Documents to gather this week

1. Three years of signed business tax returns and matching P&Ls
2. Year-to-date P&L, balance sheet, and three months of bank statements
3. Current lease, amendments, and a plain-English remaining term
4. License and permit list, including who holds each card
5. Top-customer concentration (names redacted until an NDA)

A simple Illinois close calendar

Plan six to twelve months from cleanup to close on a prepared Main Street deal. Start CBS-1 and any Chicago or Cook notices at letter-of-intent, not the week of funding. Landlord consent often takes longer than the lender.
