CLK Properties

What CLK Properties does

CLK Properties is a privately held, family-owned real estate investment and management firm founded in 1980 by Maynard and Craig Koenigsberg, headquartered in Woodbury, New York. The company operates as a vertically integrated owner-operator across two core divisions: CLK Multifamily Management, which handles day-to-day operations for a residential portfolio of 18,252+ apartment units spread across 15 states, 30 cities, and 85 properties; and CLK Commercial Management, which oversees approximately 1.5 million square feet of premier office and retail space on Long Island serving 165 corporate tenants. CLK's strategy focuses on acquiring underperforming and value-add multifamily assets in secondary and tertiary markets with stable economies, then repositioning them through renovation programs (1,485 apartments fully renovated in 2022 alone) to capture rent growth, achieving 94% stabilized occupancy and 8% year-over-year rent growth.

The business model is asset-based and recurring: revenue is generated primarily from monthly residential rental payments across the multifamily portfolio and multi-year commercial lease payments on Long Island office and retail properties, supplemented by asset appreciation realized through value-add repositioning and subsequent sale or refinancing. Go-to-market is direct — on-site leasing teams handle residential leasing while CLK Commercial Management (led by Michele Klampfer) handles enterprise office and retail leasing, and a corporate acquisition pipeline is driven by VP of Acquisitions and Capital Markets Michael Song and the firm's industry relationships. Pricing is quote-based and not publicly disclosed, varying by property, unit type, and market.

The company has no proprietary technology platform and operates as a traditional real estate firm. It is led by Craig Koenigsberg (Founder & CEO) with Jake Koenigsberg as Principal/Asset Manager and a broader team of VPs covering operations, asset management, construction, acquisitions, finance, and analytics. CLK has demonstrated sustained portfolio expansion through six multifamily acquisitions between August 2023 and November 2025, established leading market positions in Memphis (3rd largest multifamily landlord) and Baton Rouge (largest), and in February 2026 secured $115 million in Freddie Mac-backed permanent financing from Greystone to refinance Courtyards on the Park, a 918-unit condo deconversion property in Des Plaines, Illinois.
