A joint venture between The Davis Cos. and GoodFriend Storage acquired a 555-unit self-storage facility at 475 Underhill Blvd. in Syosset, New York, on July 24, 2026, per REBusinessOnline. The property spans 40,344 net rentable square feet across two floors, includes 88 boat and RV spaces, and can support roughly 34,000 square feet of future expansion. The seller and price were not disclosed.
The deal is a textbook Northeast infill play: supply-constrained submarket, vehicle storage income, and expansion land in a corridor where new development is rare. It lands the same week Public Storage closed its $10.5 billion NSA merger and Yardi Matrix reported national street rates falling 2.4% in July. National softness is not stopping institutional buyers from paying for coastal density.
What Did The Davis Cos. and GoodFriend Actually Buy?
REBusinessOnline reported the July 24, 2026 closing on July 24. The Syosset facility at 475 Underhill Blvd. sits in Nassau County on Long Island, one of the most supply-constrained self-storage corridors in the country.
| Attribute | Detail |
|---|---|
| Location | 475 Underhill Blvd., Syosset, NY (Nassau County) |
| Total units | 555 |
| Enclosed units | 467 (two floors) |
| Vehicle spaces | 88 boat and RV |
| Net rentable SF | 40,344 |
| Expansion potential | ~34,000 SF |
| Buyer | JV: The Davis Cos. + GoodFriend Storage |
| Close date | July 24, 2026 |

The two-floor layout and vehicle storage mix matter for underwriting. Boat and RV spaces generate premium rents in coastal markets where homeowners lack driveway or marina storage. The 34,000-square-foot expansion right gives the JV a growth path without competing for scarce greenfield land.
The Davis Cos. is a Boston-based investment firm with a long track record in commercial real estate. GoodFriend Storage operates as the on-the-ground operator, a structure that mirrors other July 2026 deals where capital partners pair with specialized storage operators rather than buying blind into lease-up risk.
Why Are Northeast Buyers Still Active When National Rates Are Softening?
National fundamentals cooled through July 2026. Storable's Q2 Industry Pulse showed occupancy at 78.1% with retention overtaking relocation. Yardi Matrix put surveyed occupancy at 89.7% and street rates down 2.4% month over month. Sun Belt oversupply markets face the steepest pressure.
Northeast infill assets trade on a different thesis. Supply pipelines in coastal metros run well below the national average. Yardi Matrix's Texas supply case study showed metros with trailing three-year supply below 4.5% were among the only markets posting positive year-over-year rent growth in May 2026. Long Island fits that profile.
Horizon Storage Group's Jefferson Valley acquisition in Westchester County, New York, followed the same logic: a 2022 conversion of a former big-box retail store with 55,311 rentable square feet and 405 units, brokered by JLL Capital Markets. The Syosset deal adds Nassau County exposure to a July 2026 Northeast deal tape that includes Moove In's Phoenixville, Pennsylvania, buy and Reframe Holdings' South Carolina portfolio.
Buyers are not ignoring national data. They are pricing regional divergence into their models.
What Does the Vehicle Storage Mix Add to the Underwriting?
Eighty-eight boat and RV spaces on a 555-unit site is a meaningful revenue diversifier. Vehicle storage commands higher per-square-foot rents than standard drive-up units in coastal markets, and the income stream is less correlated with apartment turnover-driven demand.
The two-floor enclosed layout also signals a denser, infill product type common in Northeast suburbs where land costs prohibit sprawling single-story development. Operators who can stack climate-controlled units and layer vehicle storage on the same parcel capture more revenue per acre than a flat drive-up prototype.
The 34,000-square-foot expansion potential is the option value in the deal. In a market where new self-storage development faces zoning headwinds, buying expansion rights with an operating asset beats ground-up entitlement risk. Whether the JV exercises that right depends on absorption data and construction costs, but the land bank alone differentiates this asset from a stabilized-only play.
How Does This Deal Fit the July 2026 Acquisition Landscape?
July 2026 delivered a bifurcated deal market. Mega-cap consolidation dominated headlines with Public Storage absorbing NSA's 1,000-plus properties. Mid-market and regional buyers kept closing single assets and small portfolios.
The Syosset transaction sits in the second bucket: operator-led, market-specific, price undisclosed. It shares DNA with SW Group's 689-unit Decatur, Texas, buy (family seller, 1031 exchange, operator expansion) and Wildcat Storage's off-market Tooele, Utah, sale, where local knowledge and relationship sourcing mattered more than auction competition.
SROA Capital's Fund X launch signals that institutional capital for undermanaged assets is not drying up. The Davis/GoodFriend JV shows that coastal infill still clears even when national street rates are falling. The buyers are not betting on a demand boom. They are betting on supply scarcity.
What Should Operators and Investors Take From the Syosset Close?
Three lessons stand out.
Coastal infill trades on scarcity, not momentum. National rate declines do not automatically flow through to supply-constrained Long Island submarkets. Underwrite the local supply pipeline, not the national average.
Operator partnerships de-risk execution. GoodFriend Storage brings operating expertise; The Davis Cos. brings capital. That JV structure is increasingly common as specialized storage operators scale without balance-sheet constraints.
Expansion rights are real option value. Thirty-four thousand square feet of developable capacity on an operating site is worth modeling explicitly, especially where new zoning approvals are difficult.
The Numbers Worth Writing Down
- Close date: July 24, 2026
- Total units: 555 (467 enclosed + 88 vehicle)
- Net rentable SF: 40,344
- Vehicle spaces: 88 boat and RV
- Expansion potential: ~34,000 SF
- Floors: 2
- County: Nassau (Long Island, NY)
- Buyers: The Davis Cos. + GoodFriend Storage (JV)
- Sale price: Not disclosed
Infill Density Beats National Averages
The Syosset deal will not make REIT earnings calls. It will not shift sector market share tables. It is the kind of transaction that defines how self-storage actually trades in 2026: regional operators and institutional capital targeting supply-constrained infill while Sun Belt developers absorb 2022-vintage deliveries.
Forty thousand square feet, 555 units, and 34,000 square feet of expansion rights in Nassau County is a bet that coastal scarcity outlasts a national rate correction. In July 2026, enough buyers still agree.
