Our Mission

To make institutional-quality real estate accessible, providing investors with cash flow, equity growth, and long-term value without the burden of active management.

Our Story

IronCrest Property Holdings was founded by Shawn Sullivan and Brett Tweedie with a clear mission: to build lasting wealth for investors through strategic multifamily real estate investments. Backed by decades of corporate leadership in strategy, operations, real estate, and data-driven execution, we have created a platform that delivers strong financial returns—built on transparency, discipline, and alignment.

At IronCrest, we acquire and reposition underperforming or value-add multifamily properties in high-growth markets across the Southeast. Our proven approach focuses on revitalizing assets, optimizing operations, and unlocking long-term value through targeted improvements. With every deal, we personally co-invest—ensuring that our success is directly aligned with yours.

We make real estate investing accessible to both accredited and non-accredited investors, offering the opportunity to earn consistent cash flow, equity appreciation, and meaningful long-term returns—without the burden of active property management.

What sets IronCrest apart is the strength of our leadership. Brett brings over 20 years of executive experience leading multi-million-dollar businesses, scaling enterprise operations, and delivering over $700M in revenue across healthcare, SaaS, and life sciences. Shawn complements this with deep expertise in analytics, strategy, and financial performance. He has overseen enterprise portfolio management functions, directing $300M+ in investments, and managed divisional budgets exceeding $100M while leading global teams of more than 300 professionals. Together, they’ve built a firm where institutional-grade strategy meets hands-on execution.

With IronCrest, you're not just investing in real estate—you're partnering with a team committed to delivering results today and building a legacy for the future.
