NEW YORK – The recession and its hangover may have turned bill-paying habits upside down. Cash-strapped Americans are paying off their car loans before they pay credit card bills and make mortgage payments, a study finds.

It used to be that Americans would pay their home loans first, then their credit card and car loans. After all, homes have been the most valuable possession for most people for decades, and nobody wanted to jeopardize that.

But TransUnion, a credit information company, studied the payment patterns of 4 million Americans with at least one car loan, one credit card and a mortgage and found a clear priority for staying current on the car loan.

Among Americans who were late on payments last year, 39 percent were delinquent on the mortgage while current on the car loan and credit cards, and 17 percent were late on credit cards while current on the other two.

Only 10 percent were late on the car loan while current on the other two.

“Today, most people need a car to get to a job or to look for a job, and that has made cars a priority,” said Ezra Becker, the company’s vice president of research and consulting.

It hasn’t helped that home prices keep falling while the mortgage remains by far the biggest payment for most people, and that millions of people owe more on the mortgage than what their houses are worth. The latest Standard & Poor’s/Case-Shiller home price index found that prices in big cities had fallen to 2002 levels.

Foreclosure also can take two to three years. Cars can be repossessed 90 days after people stop paying.
