Guardian Realty offers a wide range of services. Our Funds Management system pays close attention to cost and risk in order to really capitalize on cash flow opportunities. In Addition, we take Investment Strategy seriously. Guardian’s most important part of Investment Strategy is to closely follow and align it with the individual’s goals. The company’s Acquisition Criteria is simple, we acquire properties that have demonstrated consistent earning power. That means properties being at least 80% occupied at time of acquisition and earning good returns on equity while employing little or no debt. Our Property and Asset Management strategy helps to reduce operating costs while maintaining property values.


Guardian was founded by Marvin Lang, a second-generation real estate investor, with the goal of creating long term value through real estate investment focused exclusively on the Greater Washington, DC region. Capitalizing on the unique demographic and employment strengths of the region, Guardian successfully deployed its knowledge, experience and local focus through its family office program and network of private investors. Guardian broadened its reach in 1999 with the launch of its funds management business in order to expand services to the institutional investment community.

To date, the Company has created and operated three private real estate funds including completion of $1.5 billion in total real estate transaction volume covering more than six million rentable square feet. Institutional investors have included university endowments, pension funds, foundations and fund of funds.

Guardian’s initial fund had a long-term investment horizon and is still active. Fund I primarily seeks current cashflow and selectively sells and/or reinvests capital proceeds as opportunities may arise. Currently, the fund owns 25 commercial office properties and one apartment building.

Guardian’s second fund commenced in 2004 with $113.75 million of equity from a diverse group of high-quality institutional investors. The fund acquired 19 properties during its investment period and completed its liquidation in 2015.

Guardian’s third fund commenced in 2015 with $44 million of equity from a major institutional investor in conjunction with the acquisition of a portfolio totaling 1.4 million square feet. Fund III completed its liquidation in January 2020.


Guardian focuses on local markets where the Principals have over 70 years proven expertise and success. Our investment strategy is to acquire existing Class B and B+ (Value-Add) commercial office buildings that have value enhancement potential through repositioning, re-tenanting, refurbishing and intensive hands-on asset management. The geographic focus is within 125 miles of Washington, DC with the three primary sub-markets consisting of Washington, DC, Northern Virginia and Suburban Maryland.

Guardian seeks to acquire and proactively asset and manage properties which generate risk adjusted returns that are significantly greater than larger Class A properties. Using a hands-on team approach, Guardian’s objective is to maintain a low level of risk, generate predictable cash flow and earn superior returns. The Principals, Executive Team, senior staff and property management personnel are actively involved in every transaction.

Guardian’s business model calls for future growth of the Firm through expansion of fund management, and the strategy employed in Fund Management today is the same strategy successfully deployed on a deal-by-deal basis since inception.
