Lendmarq focuses on funding acquisitions, renovations, ground-up construction, and rental property strategies across “high-demand” US markets, offering loans including fix-and-flip, bridge, construction and DSCR financing.
The transaction will give Castlelake, a global alternative investment firm specialising in asset-based private credit, access to residential loan financing opportunities for its funds and vehicles.
A multi-year relationship with lending platforms Eastview and Lendmarq has seen Castlelake purchase more than 4,000 senior structured loans exceeding $2bn (£1.5bn) of funded volume, including RTLs, single-family-residential/DSCR loans, ground-up construction loans, and multi-family bridge loans.
The alternative investment firm has ownership stakes in four other sourcing platforms spanning specialty finance and aviation finance.
