These are the sponsor’s own numbers. They can lag what has actually sold, and they do not confirm that interests are still available.

How we work out how much has sold

We divide the amount the sponsor reports sold by the offering size in its latest SEC filing, filed Oct 6, 2026.

  • The sponsor reports these amounts itself, and can amend them later.
  • A filing can be behind what has actually sold. It does not confirm that interests are still available.
  • The amount left to sell is the offering size minus the amount sold.

Form D Item 15 and Item 16 amounts may be the issuer’s estimates; each percentage is Top1031’s arithmetic on two Form D figures. Item 16 can overlap Item 15, so Top1031 does not add them together. The issuer marked these amounts as an estimate.

Amounts, investor counts and minimums are as filed with the SEC on Form D. The change lines are Top1031’s arithmetic between consecutive filings; a new Form D notice starts a new count.

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.

Common questions

Is The Arboretum an active offering?
The Arboretum is an Active offering: its latest Form D was filed Oct 6, 2026. A Form D filing does not by itself confirm that interests are still available; the sponsor or a registered representative can confirm what is open.
What exactly does the Trust own?
One property: The Arboretum, at 20 Maple Lane in Farmingville, New York, in Suffolk County on Long Island. It holds 292 dwelling units across roughly 491,071 square feet of net leasable area, completed in 2024 on about 62 acres, and 50 of the residences are detached single-family rental homes. The Long Island Housing Partnership records 30 of the units as designated affordable two- and three-bedroom rentals.
Who bought the property, from whom, and for how much?
An affiliate of The Inland Real Estate Group bought The Arboretum from BRP Companies for $190 million. JLL announced the sale on March 2, 2026, and Inland announced the closing on March 9, 2026, reporting the community 98% occupied at that point. Baker 1031, a distributor site summarizing sponsor offering materials, dates the trust's acquisition to January 30, 2026.
Who pays the rent?
Residents do, under individual apartment, townhome and single-family-home leases, so there is no single corporate tenant. Baker 1031, summarizing sponsor offering materials, reports the trust master-leased the property to an Inland Private Capital affiliate that subleases the individual units to residents. That same source reports roughly 93.15% of units subleased as of January 19, 2026.
Does the Trust use debt, and who is the lender?
Yes, the Trust is leveraged. Baker 1031, a distributor site summarizing sponsor offering materials, reports a $104,500,000 first-mortgage loan from PNC Bank, National Association, within total capitalization of $212,081,888 made up of that debt and $107,581,888 of equity. The Form D filings themselves report only the equity offering, and loan terms are governed by the offering documents.
Who can invest, and what is the stated minimum?
Purchases are limited to accredited investors, those meeting SEC income or net-worth tests, because the Trust is offered under Rule 506(b), a private-placement exemption that bars general advertising and relies on pre-existing relationships. The Form D records a $25,000 minimum outside investment, and a sponsor may accept less at its discretion.
Could this Trust roll into a REIT at exit?
The record shows no 721/UPREIT feature, the arrangement under which some DSTs contribute their property to an affiliated REIT in exchange for operating-partnership units. Exit mechanics for this Trust are described in the offering documents, which are not public documents.
