Who is the tenant, and what's the lease?
There is no single tenant. Income comes from residents on individual apartment leases that turn over continually, rather than one long-term corporate lease as in a net-leased building. Harbor Group Management runs the property and currently markets one- and two-bedroom homes there.4
How did it end?
Still operating
No full-cycle disposition or exit has been announced; the underlying 229-unit property (rebranded 'The Mark at Mamaroneck') remains actively operated by Harbor Group Management and is currently leasing units, per the Harbor Group Management property page, while a White Law Group investigation (Apr 7, 2025) cites investor losses but does not report a sale, foreclosure, or 721 conversion.

How is it financed, and what does it pay?
The Trust carries mortgage debt on the property alongside investor equity, so fixed debt service comes ahead of investors and the loan must be repaid or refinanced at maturity. Newmark introduced the two partners and secured the acquisition financing.1 No lender, loan amount, or maturity date was located in public sources.

What does the paperwork say?
The Trust opened with an initial Form D — the brief notice an issuer files for a private placement — and has amended it twice, each amendment updating the amount sold and the number of investors. It is offered under Rule 506(b), the private path that bars public advertising and reaches accredited investors through pre-existing relationships.

Common questions
What happened to Avalon Mamaroneck?
Top1031 lists Avalon Mamaroneck in the Historical cohort because its latest filing is outside the Active window. The outcome and source documents are shown separately.
Where does Top1031 get the data for Avalon Mamaroneck?
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.
What exactly would I own?
A beneficial interest in CF Westchester Multifamily DST, a Delaware statutory trust that holds one apartment community at 746 Mamaroneck Avenue in Mamaroneck, New York, now operating as The Mark at Mamaroneck. DST interests are passive — investors have no management role — and are structured so they can be used as replacement property in a 1031 exchange. The Form D filings report a $250,000 minimum investment.
Is this Trust still open to new investors?
Top1031 lists it as raising. The most recent Form D amendment on file is dated February 21, 2024, and the SEC record does not report the offering as fully subscribed. Because Form D amendments are periodic rather than continuous, the sponsor or the selling broker-dealer is the only place to confirm whether interests remain available today.
Who manages the building day to day?
Harbor Group International's management arm, Harbor Group Management, operates the property and handles leasing; its current property page markets The Mark at Mamaroneck at 746 Mamaroneck Avenue. Harbor Group is the joint venture partner alongside the Cantor Fitzgerald affiliates that sponsored the Trust.
Could this end in a REIT roll-up (a 721 or UPREIT exit)?
The record here shows no REIT conversion contemplated. A 721 or UPREIT exit is when a DST's property is contributed to a REIT's operating partnership in exchange for units, converting a real estate position into REIT units rather than a further 1031 exchange. The disposition path for this Trust is not disclosed in the public filings.
Have there been any investor complaints about this offering?
Two law firms have published investigation pages naming CF Westchester Multifamily DST among Cantor Fitzgerald-sponsored DSTs they are reviewing for potentially unsuitable broker recommendations — KlaymanToskes on April 30, 2024 and White Law Group on April 7, 2025. These are attorney solicitations for potential claims, not court findings or regulatory actions, and no primary-record evidence of litigation, foreclosure, or a sale of the property was located.
What is not disclosed in the public record?
Occupancy, the loan amount, lender identity, interest rate and maturity, reserve levels, and any sponsor projections do not appear in the SEC filings or the press coverage. Those terms live in the private placement memorandum (PPM), the offering document the sponsor delivers to accredited investors.
