WASHINGTON (AP) — One of the country’s largest overseers of troubled home loans, Nationstar Mortgage Holdings Inc., is quietly trying to sell a $100 million insurance agency that doesn’t appear to exist.

Harwood Service Co. has no website, no independent offices and only a single registered agent. The switchboard operators at Nationstar’s headquarters in Lewisville, Texas, haven’t heard of Harwood. Call-center employees of Assurant Inc., the insurance carrier whose policies Harwood sells, say the company is just a name used to refer Nationstar business.
