Home prices hadn’t risen enough, the loan officer told him.

But last month, the same loan officer offered him more than  double the credit he needed.

“I told him I needed $25,000” on a home equity line of credit, said Klasen,  who lives in Fillmore in Ventura County. “He said we were qualified to go up to  $60,000.”

Klasen is among a wave of homeowners in California and nationally who are  again putting their homes in hock — despite the costly lessons of the housing  meltdown.

After a home equity credit binge during the housing bubble, banks shut off  the tap as home prices plummeted. Sobered homeowners stopped viewing equity as  free money for cars, vacations and college educations.

But now second mortgages are back in vogue. Homeowners in the six-county  Southern California region took out 47,542 home equity lines of credit last year — 48% more than in 2012, according to research firm DataQuick. The median credit  line was $100,000.

The same trend is taking hold nationwide. Bank  of America, for instance, saw its home equity business surge 75% last year  compared with 2012, said Matthew Potere, who oversees home equity lending for  the Charlotte, N.C., giant. In the fourth quarter, BofA issued $1.9 billion in  new home equity credit lines, up from $1 billion a year earlier.
