On this week’s episode of Multifamily Mastery, John Casmon interviews Jack Mullen. Jack shares how his background in banking and his advisory firm, Summer Street Advisors, have positioned him to help both institutional and family office investors navigate due diligence, capital calls, and distressed real estate opportunities. They dive into how LPs should evaluate whether to reinvest in troubled deals, the pitfalls of 1980s vintage multifamily projects, and why execution—not just capital markets—separates successful operators from struggling ones. Jack also offers guidance on scaling from friends-and-family deals to institutional partnerships and emphasizes the importance of professionalism, reporting, and alignment between sponsors and LPs.
