Florida-based Ocwen Financial’s loan servicing arm has inked a deal with mortgage giant Freddie Mac to service nonperforming single-family mortgages.

According to a recent SEC filing by its parent company, Ocwen Loan Servicing will operate as Freddie’s “interim servicer” on a pool of 24,000 troubled home loans, totaling $4.4 billion in unpaid principal. Compensation for Ocwen’s service was not disclosed.

Ocwen already services a portfolio of $38.4 billion in loans, according to the company’s quarterly regulatory report. The specialty subprime servicer was one of the first to begin modifying loans under the U.S. Treasury’s Home Affordable Modification Program in April.
