Castlelake is forming a joint venture with Redwood Trust to purchase up to $8 billion of prime jumbo mortgage loans.
The partnership was designed to support the growth of Redwood's Sequoia platform and give Castlelake, an investment firm specializing in asset-based private credit, programmatic purchasing power for the fully documented loans.
