Walter Investment Management (WAC) said Tuesday it completed the purchase of high-touch specialty mortgage servicer Marix Servicing. Phoenix-based Marix deals with mortgage default management, borrower outreach, loss mitigation and liquidation strategies. The current state of the nation's housing market is leading many well-capitalized firms to grow their presence in the high-touch space, where bespoke mortgage servicing is considered one of the better options for getting results. "With the close of the transaction, Marix becomes a significant component of the Walter Investment high-touch asset management and servicing platform, allowing the company to expand its portfolio acquisition and revenue growth opportunities," reads a statement from Walter Investment, a Tampa Bay-based real estate investment trust. The price remains undisclosed. Mortgage servicer Walter Investment Management specializes in subprime and otherwise distressed mortgage assets worth $1.8 billion. Annual revenues at the firm are approximately $180 million. Walter announced that it would purchase Marix in August 2010 from Marathon Asset Management, which was looking to exit the mortgage servicing business. Write to Jacob Gaffney.
