While office accounted for the largest share of dollar volume, multifamily emerged as one of the market's strongest performers, with investment volume increasing 93% as institutional investors returned to Manhattan's predominantly free-market apartment sector. Unlike the outer boroughs, where transaction activity continues to be influenced by rent-stabilized properties, Manhattan's multifamily market was driven by demand for larger free-market assets and improving pricing fundamentals.
Development activity also strengthened considerably, with dollar volume rising 54% as investors pursued assemblage opportunities and redevelopment sites. Investor sentiment was increasingly supported by City of Yes, the 467-m office-to-residential conversion program and the Midtown South Mixed-Use Plan.
The first half of 2026 reinforced Manhattan's position as New York City's most active investment market. Renewed investor confidence, improving capital markets and expanding redevelopment opportunities continued to attract institutional and private capital to high-quality multifamily, development sites, trophy office buildings and other well-located assets with strong long-term fundamentals. While buyers remain disciplined in their underwriting amid an evolving regulatory and political landscape, expanding redevelopment opportunities and continued demand for high-quality assets position Manhattan to sustain its investment sales momentum through the balance of the year.
