Benchmark Real Estate Group purchased a 90-unit prewar apartment building at 698 West End Avenue on Manhattan's Upper West Side from the Heller Organization for $42 million. The 15-story property, built in 1925, traded hands this week based on recently filed records.

Heller acquired the building in 1998 but opted to divest after holding it for roughly 25 years. The sale price of $42 million values the asset at approximately $467,000 per unit, a modest figure for Upper West Side multifamily real estate in today's market.

For current residents and future tenants, Benchmark's ownership brings a change in landlord management philosophy. Benchmark operates as a portfolio holder rather than a development-focused entity, suggesting the building will remain stabilized rental housing rather than face conversion or major renovation. Existing tenants should expect continuity, though new ownership often leads to operational changes.

Sellers benefit from market liquidity in Manhattan's core residential markets, where prewar buildings command steady institutional buyer interest. The Heller Organization timed the exit during a period of renewed appetite for stabilized income-producing assets.

For buyers like Benchmark, this represents a secure long-term hold. Prewar construction on the Upper West Side offers both irreplaceable character and stable rent rolls. At roughly $467,000 per unit, the per-door valuation remains accessible compared to newer construction, making it an attractive yield play for institutional investors prioritizing cash flow over appreciation.

The West End Avenue corridor attracts consistent demand from renters seeking established neighborhoods with transit access and institutional amenities. This makes the building suitable for buy-and-hold investors with patient capital and no immediate disposition timeline.

The transaction underscores the Upper West Side's resilience as a multifamily investment destination. Even as development activity concentrates in other Manhattan submarkets
