What Mandelbaum & Associates does

Mandelbaum & Associates, Inc. is a privately held, family-controlled real estate family office headquartered at 848 Manhattan Beach Blvd in Manhattan Beach, California. Founded in the mid-1970s by the Mandelbaum family and incorporated in 1980, the firm operates from a single office with a team of nine professionals and delivers integrated advisory and transactional services across the full real estate lifecycle — acquisition assistance, disposition assistance, 1031 repositioning (forward and reverse), new development investment, redevelopment, local property management, asset management, and financing and refinancing assistance. The business was built on the Mandelbaum family's direct investing experience in Southern California residential rentals, expanded into third-party management in the early 1980s, and grew geographically through 1031 exchanges into Nevada, Texas, Arizona, New Mexico, Oregon, Utah, and Washington, with later expansion into multifamily development in the late 1990s and early 2000s. A March 2026 transaction — a $5.5 million preferred equity co-investment in Bayshore Properties' acquisition of the 253-unit Aspen Ridge Apartments in West Chicago alongside $32.6 million of Freddie Mac financing arranged by Greystone — also evidences selective principal capital deployment beyond the firm's historical Western/Southwestern footprint.

The firm serves a narrow client base of high-net-worth real estate families and family offices, with publicly disclosed testimonials referencing relationships of 25 to over 30 years. Revenue is generated through professional services fees — a mix of recurring asset and property management fees and transaction-based fees tied to acquisitions, dispositions, refinances, and 1031 repositionings — under a bespoke, quote-based pricing model with no publicly disclosed rates. Go-to-market is relationship-driven: the firm relies on referrals from existing client families and on an ecosystem of 92+ partner relationships (brokers, lenders, developers, service providers) rather than on self-serve or digital channels. The corporate website (mandelbaum.com) and a directly listed phone number (310.545.5400) serve as the primary intake touchpoints. The firm has no disclosed AI/ML capabilities, no proprietary software platform, and no APIs; the entire offering is human-led advisory and transaction execution, supported by in-house accounting, bookkeeping, and property management staff plus third-party fee managers at remote sites.
