Self Storage Investing 2026: REITs, Non-Traded and Syndications

Route 1: listed REITs, and the one that disappeared in July

A listed self-storage REIT is the only route here where you can sell today at a quoted price. The latest 10-Qs give the operating numbers behind that price. We read each company's same-store table for the three months ended June 30, 2026 (National Storage Affiliates for the quarter ended March 31, 2026, its last report).

Source: Forms 10-Q for the quarter ended June 30, 2026 (Public Storage, accession 0001628280-26-050612; Extra Space, 0001289490-26-000053; CubeSmart, 0001298675-26-000038; SmartStop, 0001585389-26-000014) and for the quarter ended March 31, 2026 (National Storage Affiliates, 0001628280-26-030519). The companies define rent per square foot and same-store revenue differently: Public Storage's is rental income before late charges and administrative fees, Extra Space's is net of discounts and bad debt, SmartStop's revenue excludes tenant-protection income. Percent changes labeled as ours are our arithmetic.

Three things stand out.

The same quarter produced opposite NOI results. Public Storage reported same-store revenue down 0.6% and NOI down 2.2%; Extra Space reported rental revenue up 2.4% and NOI up 3.5%. The 5.9-point gap between Public Storage and SmartStop (our arithmetic) reflects different portfolios and pricing choices (our reading). Public Storage says its realized rent per occupied square foot fell because of “lower average rates per square foot charged to new customers moving in as compared to customers moving out”; Extra Space's new-lease rent per square foot was $14.02 against $14.12 a year earlier, while the rent it collects from all occupied space, $19.95, rose from $19.50. Public Storage says new customers pay less than the ones leaving; Extra Space's figures show new leases at $14.02 against $19.95 for all occupied space. That is why we show both numbers.

Occupancy is high and flat. All four moved by 0.6 point or less from last year. SmartStop's average same-store occupancy fell 0.6 points to 92.5%; it says same-store revenue rose “primarily due to an approximately 1.9% increase in annualized rent per occupied square foot, slightly offset by a decrease in occupancy of approximately 0.6%”. Extra Space's period-end same-store occupancy was 94.2% against 94.4%.

Public Storage absorbed a competitor. On July 22, 2026, Public Storage announced the completion of its acquisition of National Storage Affiliates under a merger agreement dated March 16, 2026. Each NSA common share became 0.1400 newly issued Public Storage common shares, and the 10-Q says Public Storage issued approximately 11,200,000 common shares to former NSA holders and equity-award holders. NSA's operating partnership also contributed a subset of properties to a new joint venture in which participating unit holders hold an $800 million equity interest, Public Storage holds $200 million and provides a $237 million mezzanine loan. The combined company, Public Storage says, owns and/or manages over 4,500 locations. For an investor the practical result is that the list of listed self-storage REITs is now Public Storage, Extra Space, CubeSmart and SmartStop, plus a very small fifth, Global Self Storage, which owned twelve stores at June 30, 2026. EDGAR shows a Form 25-NSE for NSA on July 22, 2026 and a Form 15-12G on August 3, 2026. Our SmartStop review covers how that company got to the NYSE on April 2, 2025, and our page on non-traded versus publicly traded REITs explains what the quoted price does and does not tell you.

Route 2: a non-traded self-storage REIT, read from its own 10-Q

Non-traded means no market price: the board sets a value and the company decides whether it will buy shares back. The one we read here is Strategic Storage Trust VI. Its sister company, Strategic Storage Growth Trust III, is being merged into it (see our SST VI and SSGT III merger page); this section uses only SST VI's 10-Q for the quarter ended June 30, 2026.

Source: Strategic Storage Trust VI, Inc. Form 10-Q for the quarter ended June 30, 2026, accession 0001193125-26-344918. The distribution total includes cash paid to common holders, preferred holders and operating-partnership unitholders plus reinvested distributions. Annual figures and percentages labeled as ours are our arithmetic.

The row to read twice is “Where did the cash come from?” A distribution is not a return if the company is paying it with the money new investors brought in. SST VI discloses the split itself, and the 10-Q's own risk wording says distributions “may be paid in part from debt financing or from proceeds from the issuance of common stock in our offerings”. The 58.2% from offering proceeds is a statement about 2026's first half only; the filing also says operating cash flow covered none of the first half of 2025's distributions (0.0%).

It is also still selling. On December 3, 2025 SST VI filed a Form D for a $75,000,000 private offering under Rule 506(c), and the form states a maximum of $4,500,000 in sales commissions and $2,625,000 in dealer manager fees, which add to $7,125,000 or 9.5% of the offering (our arithmetic). On March 6, 2025 a related SmartStop vehicle, Strategic Storage Trust X, filed a Form D for $650,000,000 under Rule 506(b) with up to $12,935,000 of commissions and dealer manager fees. Neither number says whether the stores pay. They show the maximum selling costs the forms allow. Our page on private REITs in Form D data covers that structure across sponsors.

Route 3: private syndications and DSTs, counted from Form D

Most of the storage deals pitched online are private: a sponsor forms an LLC or limited partnership for one facility or a fund of them and files a Form D with the SEC. We have not found a published count of how many exist. We counted them from the SEC's quarterly Form D data sets, the same data we used in our real estate partnership census.

How we counted. We took original Form D filings (amendments excluded) from January 1, 2020 to September 30, 2026 whose primary issuer's name contains “storage”: 827. We set aside 56 that are not self-storage real estate (energy storage, cloud and data storage, cold storage and industrial outdoor storage), 21 REIT preferred-share placements of $62,500 to $125,000 that only give a REIT its 100 holders, and 7 filings by Extra Space Storage LP, leaving 743. The filter has limits: a sponsor whose entities do not say “storage” is missed, and a Form D shows what the sponsor says it is raising, not what it earned.

Source: SEC Form D data sets, 2020q1 to 2026q3, original filings by filing date; our census script and its output are saved with this page. Shares and counts are our arithmetic.

Filings fell 47.6% from the 2022 peak to 2024 and then stopped falling: 86 in 2025, and 66 in the first nine months of 2026 against 61 in the same months of 2025. What changed is how the deals are sold. Rule 506(c) is the part of the rule for “offerings not subject to limitation on manner of offering” (17 CFR 230.506(c)), which in our reading is what lets a sponsor advertise, and it says “All purchasers of securities sold in any offering under paragraph (c) of this section are accredited investors” (17 CFR 230.506(c)(2)(i)). Its share of storage filings doubled from 21.8% in 2020 to 43.0% in 2025.

What the 238 filings since 2024 look like

Using the 238 filings dated January 1, 2024 to September 30, 2026:

Source: SEC Form D data sets, 2020q1 to 2026q3; filings dated January 1, 2024 to September 30, 2026. Percentages and medians are our arithmetic. Amounts sold are the figure on the latest filing, amendment or original, for the same SEC file number; a master fund and its feeder can both count the same dollars.

Two patterns are specific to storage. First, one legal entity per property: 13 filings carry the name prefix FreeUp Storage, 9 start with “Storage Units” (7 ground-lease LLCs and 2 by one management corporation) and 8 are series of CAP Storage Management. A sponsor with ten stores may have ten entities and ten Form D filings, so 238 filings are fewer sponsors than that. Second, the biggest numbers belong to a few funds. The largest stated offerings include Strategic Storage Trust X at $650,000,000 (2,000,000 sold to one investor at the first filing), Merit Hill Self-Storage VI at $500,000,000 (none sold on its latest filing), Blue Doors Storage Fund VI at $200,000,000 ($74,192,000 sold to 24 investors) and Sterling Self Storage Master Fund I at $200,000,000 ($61,975,428 sold to 169 investors, minimum $100,000). Prime Storage Fund III In-Kind Contribution Fund reports $383,624,953 sold to 34 investors under an indefinite offering. These are the filings behind the “institutional” storage funds, and they are not open to a $50,000 check.

The DST route, and what its Form D says about fees

A DST is the 1031-exchange vehicle (our DST guide explains it). Storage DSTs in the data include NexPoint Storage V DST ($46,439,932 offered and sold, 99 investors, $100,000 minimum), IREX II Storage Portfolio DST ($85,695,652 offered, $80,663,234 sold, 70 investors, $250,000 minimum) and Inland Self-Storage Portfolio XXII DST ($115,869,677 offered, $1,188,807 sold to 2 investors on the first filing of February 5, 2026).

Source: Form D filings, accessions 0002051995-25-000001 (NexPoint Storage VI DST) and 0002109604-26-000001 (Inland Self-Storage Portfolio XXII DST). Percentages are our arithmetic; the forms mark the commission figures as estimates. Our DST fee analysis and Inland Private Capital DST page cover the fee structure in more detail.

For the 5.0% to 8.75% of commissions plus a further 6.3% to 13.5% of stated costs, the investor buys a fixed, illiquid slice of a storage portfolio. Compare that with the listed route, where the cost is a brokerage commission, and the non-traded route, where SST VI's own private placement stated up to 9.5%.

Why a storage owner can sell the contents of an unpaid unit

A storage owner collects from a tenant who stops paying differently from a landlord of a home: it sells the stored goods under a statutory lien instead of going to court for an eviction (our reading). We read one state's statute, Florida's Self-storage Facility Act (Florida Statutes sections 83.801 to 83.809), on the Legislature's site on October 13, 2026. Other states have their own versions with different notice periods, which we did not read.

• The lien exists from the first day. Section 83.805 says the lien “attaches as of the date that the personal property is brought to the self-service storage facility”.
• The tenant gets 14 days. The notice must include “A demand for payment within a specified time not less than 14 days after delivery of the notice” (section 83.806(2)(c)).
• The sale is advertised. It is published once a week for two consecutive weeks in a newspaper, or run on a public website that conducts personal property auctions (section 83.806(4) and (4)(a)), and “shall take place at least 15 days after the first publication” (section 83.806(4)(b)).
• The tenant can redeem until the sale. Under section 83.806(6) the tenant may pay the lien and reasonable expenses “and thereby redeem the personal property”.
• A buyer is protected even if the owner slipped. Section 83.806(7) says a good-faith purchaser takes the property “free of any claims, except those interests provided for in s. 83.808, despite noncompliance by the owner with the requirements of this section”.
• The surplus belongs to the tenant for two years. Under section 83.806(8), balance proceeds are held for the tenant and, if unclaimed within 2 years after the sale, “shall be deemed abandoned”.

In our reading, that timeline (a 14-day demand, then a sale at least 15 days after the first advertisement) is what lets an owner clear a delinquent unit within weeks. It is also why the 10-Qs above report “late charges and administrative fees” as a revenue line: Public Storage's same-store late charges and administrative fees fell 1.7% in the quarter. For an investor the point is narrower: occupancy and rent per square foot in the tables are what is left after the owner has run this process.

What a reader can do with this

• Decide which question you are asking. If you want to sell next month, only the listed route answers yes. If you accept no exit in exchange for a sponsor's projection, you are in Routes 2 and 3, and the filings above show what those cost.
• Read the same-store table in the latest 10-Q before the headline. The three numbers to find are average occupancy, rent per occupied square foot and same-store NOI. Two companies in the same quarter reported NOI moves of -2.2% and +3.5%.
• For a non-traded REIT, find the “sources of distributions” table. SST VI prints it, as 18.4% operations, 58.2% offering proceeds and 23.5% reinvestment in the first half of 2026. Then find the redemption note: here it is suspended except for death, long-term care, qualifying disability or bankruptcy.
• For a syndication, look up the sponsor's Form D on EDGAR. Search the exact entity name. Check the offering amount, the minimum, whether it is Rule 506(b) or 506(c), the commissions line and how much is already sold. A sponsor that has filed one Form D per property tells you it raises property by property.
• Ask what the fees are before the first rent check. The two DST forms above state commissions of 5.0% and 8.75% of the offering; SST VI's private offering states up to 9.5% in commissions and dealer manager fees (all our arithmetic).
• Check your eligibility. Rule 506(c) deals are for verified accredited investors only; our page on qualified purchaser vs accredited investor explains the thresholds.
