Who is the tenant, and what's the lease?
No single corporate tenant sits here: income comes from hundreds of individual resident leases that turn over and reprice. Baker 1031, citing sponsor materials, reports the Trust is master-leased to an Inland Private Capital affiliate, with Inland affiliates handling management; no public filing confirms those terms.4 JLL reported the community 98% occupied when the sale was announced.2

What does the paperwork say?
The initial Form D — the notice the SEC requires when an issuer sells securities under a private-placement exemption — set the offering total, and each amendment since has updated the amount sold and the investor count. Rule 506(b) bars general advertising and limits buyers to accredited investors, those meeting SEC income or net-worth tests.

A Form D is the notice a sponsor files when it starts raising money. A Form D filing does not mean the SEC approved, endorsed, or verified the offering.
DST interests are illiquid private securities. You may lose some or all of your investment. Distributions, tax treatment, and exit timing are not guaranteed. Review the current Private Placement Memorandum before investing.
Common questions
Is The Arboretum still raising money?
Top1031 lists The Arboretum as active because the sponsor is still filing with the SEC. That does not confirm that interests remain available.
Where does Top1031 get the data for The Arboretum?
Top1031 builds this record from the sponsor’s own SEC filings and cited sponsor disclosures. Filings can lag what is happening now. A Form D filing does not mean the SEC approved, endorsed, or verified the offering.
Is this Trust still open to new investors?
Yes. Inland Long Island Residential DST was still raising as of its most recent Form D amendment, filed August 21, 2026, with 11 filings on its SEC record. That amendment reports a first sale on February 23, 2026. The amount sold, the amount still available and the reported investor count appear in the sales rows on this page.
What exactly does the Trust own?
One property: The Arboretum, at 20 Maple Lane in Farmingville, New York, on Long Island. It has 292 dwelling units across roughly 491,071 square feet of net leasable area, on a 62-acre site. Inland's acquisition release describes the community as newly constructed in 2024, with lofts, flats and townhome-style units plus 50 detached single-family rental homes, and amenities including a pool, fitness center, courts, a playground and a seven-acre park.
Does the Trust use leverage?
The public filings do not say. The Form D reports only the $107,581,888 of equity being offered, with no lender, loan balance or maturity, and Top1031's filing-derived record lists leverage as unknown. Baker 1031, a third-party 1031 marketplace, reports approximately $104.5 million of debt based on sponsor materials, but the Form D does not independently confirm those loan terms. JLL separately reported a $91 million floating-rate Santander Bank construction loan for the BRP Companies/BlackRock joint venture that built the property — that is prior-owner development debt, not debt of this Trust. The Private Placement Memorandum is where a buyer confirms whether the Trust carries a mortgage and on what terms.
Who can invest, and what is the stated minimum?
The Trust is offered under Rule 506(b), a private-placement exemption that bars general advertising and relies on pre-existing relationships, so participation is limited to accredited investors — those meeting SEC income or net-worth tests. The Form D reports a $25,000 minimum outside investment; a sponsor may accept less at its discretion.
Is there a master tenant, and how full is the property?
The income stream is hundreds of individual apartment and single-family-home leases rather than one corporate lease. Baker 1031 reports, from sponsor materials, that the Trust is master-leased to an Inland Private Capital affiliate with Inland affiliates handling asset and property management; no public filing reviewed confirms those arrangements. On occupancy, the dated public statements come from the sale: JLL Capital Markets called the community 98% occupied in its March 2, 2026 announcement, and Inland reported it 98 percent occupied at closing on March 9, 2026. No public filing for this Trust reports occupancy after that date.
Could this become REIT shares through a 721/UPREIT exit?
Nothing in the record indicates a 721 or UPREIT exit — a later contribution of the property into a REIT's operating partnership in exchange for REIT units. The record shows no such conversion path for this Trust, and the PPM governs any exit mechanics.
