The ongoing investigation of the industry, "The Mobile-Home Trap," has focused on Clayton Homes, a company owned by Warren Buffett’s Berkshire Hathaway that dominates mobile-home lending, sales and manufacturing. Clayton builds nearly half the new manufactured homes sold in this country every year, sells them through a network of more than 1,600 dealerships, and finances more than a third of all mobile-home loans, more than any other lender by a factor of seven.

When people fall behind on their loans, Clayton repossesses the homes and resells them.

Bonlender said the study could offer the Legislature some potential solutions when lawmakers return for their long legislative session in 2017.

The bill is sponsored by Rep. Cindy Ryu.

At the federal level, an industry-backed plan to roll back consumer protections has stalled in recent months. Last April, the U.S. House approved a bill that would raise the interest-rate thresholds at which additional consumer protections would take effect. The bill would overwhelmingly help Clayton Homes.

The proposal was also included in a larger U.S. Senate bill last year that was approved in a committee but did not make it to the Senate floor.

After a story in December alleging Clayton systematically targets minority borrowers and charges them higher rates, senior Democratic lawmakers called for a federal investigation of the company.
