Frequently asked questions
Who is John J. McMahon and how did he build his wealth?
John J. McMahon founded Lone Star Funds in 1995, building it into one of the world's largest distressed-asset investors. Lone Star became known for buying non-performing loan portfolios and distressed real estate globally, with landmark deals including the 2004 acquisition of Korea Exchange Bank. McMahon stepped back from running the firm in 2010 and remains one of the wealthiest figures in private equity.
What asset classes does McMahon Capital Management target?
The office concentrates on real estate equity, private credit, and select energy-transition infrastructure. Within real estate, McMahon seeks distressed and special-situation commercial assets, multifamily development, and non-performing loan portfolios in both US and European markets. The credit side focuses on transitional lending for properties undergoing repositioning.
Does McMahon Capital Management accept outside capital?
No. McMahon Capital Management operates strictly as a single-family office and does not raise third-party capital. It deploys John McMahon's personal wealth without the LP constraints common to his prior institutional investing at Lone Star.
Is McMahon Capital related to Lone Star Funds?
McMahon Capital Management is the family office of Lone Star Funds founder John J. McMahon — it is not a subsidiary or related fund of Lone Star. However, the office's investment strategy overlaps significantly with the real estate and credit mandates McMahon built at Lone Star, and he has occasionally co-invested with former Lone Star executives.
How does McMahon source investment opportunities?
Sourcing relies heavily on McMahon's network from two decades at Lone Star — former partners, banking relationships, and service providers in distressed markets who bring off-market deals directly to the office. The firm has established co-investment relationships with institutional operators like Greystar and likely uses a lean team of investment professionals to evaluate complex, cross-border situations.
