Frequently asked questions

Who runs investment decisions at Mark IV Capital?

President Kurt Wittek leads the firm's overall strategy, with Director of Investments Brendan Wittek overseeing day-to-day deployment. The office functions as a closely held family operation with investment authority concentrated among senior family principals.

How does Mark IV Capital source its real estate deals?

Mark IV Capital relies on a multi-decade network of regional brokers, developers, and operating partners across the Western US. Its long track record as a direct acquirer and developer in Southern California, Arizona, and Nevada gives it early visibility into off-market and pre-marketed opportunities.

Does Mark IV Capital take outside capital or operate as a fund manager?

No. Mark IV Capital deploys exclusively proprietary Wittek family capital and does not accept outside investors. This balance-sheet-only structure eliminates fund-cycle constraints and allows the firm to hold assets indefinitely.

What investment stages and asset types does the firm target?

The firm focuses on direct ownership and ground-up development of industrial, multifamily, and select office properties. It also pursues opportunistic private credit investments, typically secured by real estate or hard assets, and may participate in special situations that offer asymmetric return profiles.

Where does the underlying wealth come from?

The Wittek family's wealth originated in Southern California commercial real estate development during the 1960s. The family formalized its investment activities through Mark IV Capital in 1974, and the office has since compounded returns through disciplined property acquisition and development across the Western US.

Are the Wittek family's philanthropic activities managed through Mark IV Capital?

The family maintains its philanthropic giving separately from the investment office. Mark IV Capital is exclusively an investment vehicle and does not manage charitable foundations or grant-making programs.

What is Mark IV Capital's posture on co-investments and joint ventures?

The firm selectively partners with local developers and operators on larger ground-up projects, but does not operate an open co-investment program for external GPs. Joint ventures are typically structured with a known operating partner where Mark IV contributes patient, balance-sheet capital alongside the partner's development expertise.
