Single Family Office

Sullivan Haymaker

John Haymaker and John Sullivan run their eponymous family office with a distressed, all-cash posture on US commercial real estate in secondary markets.

Sullivan Haymaker

Sullivan Haymaker operates as the private investment vehicle for principals John Haymaker and John Sullivan, whose wealth stems from decades of opportunistic real estate acquisition and development. The firm's structure reflects the partnership roots of its founders — a lean, principal-led operation that evaluates each deal on its standalone merit rather than against a pooled fund mandate. The firm's investment strategy concentrates on US commercial real estate, with a demonstrated appetite for distressed and value-add opportunities across office, retail, and multifamily assets. Sullivan Haymaker typically targets secondary and tertiary markets where institutional competition is thinner and cap-rate compression is less severe. The principals are known for all-cash execution and a willingness to absorb operational complexity that deters conventional buyers — including fractured tenant rolls, environmental remediation requirements, and zoning entanglements. Sullivan Haymaker maintains no outward-facing investor relations infrastructure; the office does not market to external LPs and has historically funded acquisitions entirely from principal capital. This permanent-capital posture allows the firm to disregard market-timing pressures. The geographic footprint has historically centered on the Southeastern and Midwestern United States, where the principals have established long-term broker and property-manager relationships that function as an informal proprietary sourcing network. What distinguishes Sullivan Haymaker from other single-family real estate offices is the partnership's dual-operator model. Both Haymaker and Sullivan are active principals with overlapping but distinct networks, and the office makes no investment unless both partners underwrite the deal personally — an internal consensus requirement that functions as a structural check on concentration risk and conviction-drift.

Frequently asked questions

Who runs investment decisions at Sullivan Haymaker?

Does Sullivan Haymaker accept third-party capital or co-investors?

What types of real estate does Sullivan Haymaker target?

The firm concentrates on distressed, value-add, and operationally complex commercial real estate. Asset classes typically include office, retail, and multifamily properties located in secondary and tertiary US markets, where deal flow is less competitive than gateway cities.

Where does the underlying wealth come from?

Is Sullivan Haymaker structured as a single family office or does it operate more like a real estate investment firm?
