Flexible Finance, a fintech firm that offers residential landlords the ability to draw rent in installments, signed a 41,000-square-foot lease for the top three floors of Rockrose Development’s 300 Park Ave. S. The move from its previous location at 33 Irving Place represents a significant expansion for the company.
“This off-market transaction is a testament to the continued strength of the Park Avenue South corridor and the tech sector’s renewed confidence in the market,” said Cushman & Wakefield’s Drew Braver, who negotiated the deal on behalf of the landlord.
Braver’s team also included Matthias Li, Remy Liebersohn, Heather Thomas and Josh Kuriloff. Ryan Alexander and Jared Isaacson of CBRE represented the tenant.
With the Flexible Finance lease, the 15-story Manhattan office space is now 90% occupied, capping off a strong year of leasing activity. Other recent tenants include AI company Basis — which took 13,671 square feet — and private equity firm TCG Capital, which leased 4,533 square feet. Brokers on the deals included Mike Mathias and RJ Johns of Cushman & Wakefield for Basis, as well as Simon Landmann and Matthew Astrachan of JLL for TCG.
Following the recent leasing momentum, Rockrose and Cushman & Wakefield are now marketing the building’s entire fourth floor, which features a pre-built office space designed by architect MKDA.
Blending historic character with modern design, the 200,000-square-foot office property at 300 Park Ave. S. — also known as the Mills & Grubb Building — offers a unique opportunity for tenants. Originally constructed in 1910, the property features a shared roof deck with sweeping city views, high ceilings and large floor plates. Located near Union Square and Madison Square Park and with a subway entrance right outside, 300 Park Ave. S. provides tenants with outstanding access to transit, dining and retail.
