Prosperity Partners Secures Full Floor at 575 Madison Avenue in Midtown East Relocation

Midtown Manhattan's Park Avenue corridor continues to attract professional services tenants, with accounting and business consulting firm Prosperity Partners signing a 24,426-square-foot lease at 575 Madison Avenue. The Chicago-headquartered company committed to a full-floor space on the 11th story of the 25-story tower, marking a strategic relocation within the Midtown East submarket.

The deal represents another full-floor transaction in a building that has maintained steady occupancy despite broader market headwinds. Prosperity Partners will occupy the entire 11th floor, taking advantage of the tower's floor plates and proximity to major transit hubs.

Key Details

• Tenant: Prosperity Partners, a Chicago-based accounting and business consulting firm
• Landlord: Steinberg & Pokoik
• Square Footage: 24,426 square feet
• Floor: Full 11th floor
• Lease Term: 10 years
• Building: 575 Madison Avenue, a 25-story office tower located between East 56th and East 57th streets
• Brokerage: CBRE represented the landlord in the transaction

According to Commercial Observer, the tenant is relocating its offices to the Midtown property, though specific financial terms including asking rents were not disclosed.

Market Context

The transaction adds to a growing list of professional services firms anchoring themselves in Midtown Manhattan, a submarket that has demonstrated resilience through the post-pandemic recovery period. Accounting firms and financial consultancies have consistently ranked among the most active tenant categories in the Manhattan office market, often seeking buildings with established ownership and centralized locations.

575 Madison Avenue benefits from its positioning between two major cross streets and relatively close access to Grand Central Terminal, making it a practical choice for firms requiring client-facing offices. The Steinberg & Pokoik-owned asset competes within the broader Park/Madison Avenue corridor, where landlords have focused on tenant retention and attracting firms prioritizing location quality over trophy-building amenities.

The 10-year lease length also stands out amid a market where tenants have increasingly pushed for shorter commitments. A decade-long term suggests Prosperity Partners is making a long-term bet on Midtown East and potentially secured favorable concessions in exchange for the extended duration.

For CRE professionals monitoring the Midtown submarket, this deal reinforces that Class A and Class B+ assets in the Madison Avenue corridor continue to lease when ownership provides competitive terms and responsive dealmaking. CBRE's involvement as landlord broker indicates institutional-level marketing for the property, which could signal additional availability or a broader leasing strategy underway at the tower.
