Thanks for your prompt reply, ***. I called back and they said that they don't modify 2nd loans with fixed rates. I find this strange. They said the investor was Greenpoint. Greenpoint was a subsidiary of CapitalOne. CapitalOne closed it down but the servicer continued to be Greenpoint.
CW then became the servicer in November 2008. I'm surprised that Greenpoint/CapitalOne didn't sell the loan off to a new investor. How can I confirm with certainty who, in fact, the investor really is?
