Cathartes

What Cathartes does

Cathartes is a private real estate development firm headquartered in Portsmouth, New Hampshire with a regional office in Boston, Massachusetts. Founded in 1992 and operating across New England for over three decades, the company develops mixed-use, multifamily residential, hospitality, commercial, industrial, and sustainable energy projects. Its portfolio includes more than 700 housing units, 500 hotel rooms, and 50,000 square feet of managed commercial space, with cumulative investments of approximately $1.5 billion across the Northeast. Cathartes pursues projects through joint ventures with hotel operators (Marriott, Hilton, IHG), institutional investors, and local municipalities, often acting as a master developer on complex urban revitalization sites.

The firm centers its developments on a "Smart Living" framework that integrates four pillars: Balance (coworking and live-work spaces), Wellness (fitness, meditation, outdoor space), Sustainability (LEED-certified construction, solar initiatives such as Westford Solar Park), and Community (arts, local business, events). Notable achievements include the first LEED-certified hotel in New Hampshire (Marriott Residence Inn) and the first Marriott Residence Inn globally to earn LEED Silver. Active product launches for 2024-2026 include Cochecho Waterfront Development (220 units in Dover, NH), Thompson's Point (257 units in Portland, ME), The Maris (45 luxury condominiums in Portsmouth, NH), and 105 Bartlett (151 units in Portsmouth, NH).

Cathartes generates revenue through a develop-and-exit model, selling stabilized assets to institutional buyers such as REITs (e.g., Chatham Lodging Trust), retaining select properties as income-producing assets, earning development fees on joint ventures, and collecting rental income from residential and commercial leasing. The customer base spans residential tenants and condominium buyers, hospitality operators under franchise agreements, commercial and industrial tenants, and institutional capital partners including Canyon Johnson Investment Fund, Beacon Capital Partners, and the State of Massachusetts.
