Recorded in NYC property records.
- Borrower
- 370 19th Street LLC
- Lender
- Hirshmark Capital
- Traded.co identifies the actual lender as Hirshmark Capital, a private commercial real estate lender -- Customers Bank, the party named directly on the ACRIS mortgage, likely served as a recording or trustee bank rather than the economic lender, a pattern seen elsewhere in this project's research.
- The loan refinances a prior $7.7 million loan from M&T Bank on the same property.
- The building is a 40,300-square-foot industrial property, working out to roughly $273 per square foot on the new loan amount.
- Traded.co's own market label for the property is "Greenwood Heights," the same informal name already documented nearby at 413-421 20th Street -- not one of the four projects currently in Hush Street's Park Slope Tracker registry.
Overview
On July 9, 2026, Eugene Mendlowitz's 370 19th Street LLC closed an $11 million refinancing on a 40,300-square-foot industrial property at 370 19th Street, on the Park Slope/Sunset Park border. The ACRIS mortgage document names Customers Bank as the party of record, recorded twice; Traded.co's own deal page instead identifies the actual lender as Hirshmark Capital, a private commercial real estate lender -- read as Customers Bank likely serving as a recording or trustee bank for Hirshmark's loan rather than the economic lender itself, a pattern Hush Street's own research has found recurring elsewhere in Brooklyn.
Traded.co confirms the new loan replaces a prior $7.7 million loan the same borrower held with M&T Bank -- a straightforward refinancing on an existing industrial building, not new construction or a change in ownership.
Traded.co's own market label for the property is "Greenwood Heights," the same informal neighborhood name already documented on the nearby 413-421 20th Street Deal -- not one of the four projects currently in Hush Street's Park Slope Tracker registry.
A confirmed $11 million refinancing that replaces a smaller prior loan on an existing industrial building -- real capital activity on the Park Slope/Sunset Park border, in a corner of the neighborhood ("Greenwood Heights") this Tracker doesn't yet separately track, and a second example of an ACRIS-named bank turning out to be a recording vehicle for a private lender rather than the actual source of the money.

Counts and combined values are computed from Hush Street’s own published Deal records only. “Combined” is the total value of the transactions a party appears on, not capital deployed by that party, and two parties on the same transaction each reflect its full amount. Not a career or market total.
Marks shown are Hush Street editorial monograms, generated from each party’s recorded name — not official company logos.
