Mansur & Company
Mansur & Company was founded in 1975 by Harold E. Eisenberg, who continues to serve as its managing principal. The firm operates out of Chicago and invests directly in commercial and residential real estate throughout the United States. Its core activities span acquisition, management, and development, with a portfolio that includes retail, office, industrial, hotel, and multifamily properties. The investment approach centers on direct ownership and active asset management rather than pooled fund vehicles. Mansur pursues value-add and opportunistic strategies across its target property types, concentrating on transactions where operational improvements can drive returns. The geographic footprint covers multiple US regions, with historical activity documented in the Midwest and Southeast. The firm has executed deals involving retail centers, suburban office complexes, and hospitality assets. Mansur operates as a privately held investment company without publicly reported assets under management. Its team size is not disclosed. In recent years, public record indicates the firm has maintained a low-profile posture, executing property-level transactions without broad press coverage. There are no known adjacent vehicles, philanthropic foundations, or co-investment clubs operating under the Mansur umbrella. Mansur's structural distinction lies in its five-decade track record as a direct principal investor that has not adopted the fund-management model common among institutional real estate managers. The firm invests its own capital alongside select partners, avoiding the fee-structure incentives and fundraising cycles that shape most private real estate platforms. Succession planning remains opaque, with founder Harold Eisenberg still holding the top leadership role after nearly 50 years.

Frequently asked questions
Who runs investment decisions at Mansur & Company?
Harold E. Eisenberg has led Mansur & Company as managing principal since founding the firm in 1975. Michael R. Mansur serves as senior vice president, representing the next generation of family involvement. The firm operates with a lean leadership structure typical of privately held, direct-investing real estate platforms, where the managing principal retains authority over acquisition and disposition decisions.
What real estate asset classes does Mansur & Company target?
Mansur invests across retail, office, industrial, hotel, and residential properties. The firm pursues both commercial and multifamily assets, with a history of value-add and opportunistic transactions. This multi-asset approach allows the firm to shift capital allocation across property types depending on market conditions, rather than being locked into a single sector mandate.
Does Mansur & Company raise third-party funds or invest its own capital?
Mansur operates as a principal investor, deploying its own capital directly into property acquisitions. Unlike institutional real estate managers that raise closed-end funds with defined investment periods, Mansur has maintained a direct-ownership model for five decades. The firm may partner with co-investors on specific transactions, but its core identity is balance-sheet investing rather than fund management.
How does Mansur & Company source real estate deals?
Mansur sources transactions through a combination of long-standing broker relationships and direct outreach, a model consistent with its five-decade presence in Chicago commercial real estate. As a repeat buyer with a track record of closing without financing contingencies, the firm likely accesses off-market or limited-competition opportunities. Specific sourcing channels are not publicly detailed by the firm.
What is Mansur & Company's geographic focus?
Mansur invests throughout the United States, with historical acquisition activity concentrated in the Midwest and Southeast regions. The firm's Chicago headquarters anchors its presence in the Midwest commercial real estate market. The diversified geographic approach reflects a strategy of pursuing value wherever it can be identified, rather than limiting investment to a single metropolitan area or region.
