Clayton Holdings, a provider of loan due diligence, surveillance, REO management and consulting services to the mortgage and real estate industries, acquired Red Bell Real Estate, and its sister company, Main Street Valuation.

Red Bell provides valuation products, including automated valuation models and broker price opinions used by major investors, lenders and loan servicers. Clayton also offered BPOs, but is now expanded into the AVM universe.

Additionally, the company offers advanced technology solutions that help investors monitor loan portfolio performance and direct loss mitigation activities, along with several other tools.

"This acquisition significantly enhances the array of sophisticated solutions that we can offer to our respective clients," said Joe D'Urso, Clayton's president. "Red Bell is an important step in our strategic road map, and will serve as the platform and the foundation for new initiatives within the broader real estate market."

Red Bell will continue to operate under its current brand and remain in Salt Lake City, Clayton said. Jeffrey Jonas, Red Bell's co-founder, and his senior management team are also staying in place. No other terms of the transaction were announced.

Back in May of 2014, Radian (RDN) acquired Clayton Holdings, paying $305 million in cash to purchase the company. Radian will repay all of Clayton’s outstanding debt as part of the purchase agreement.
