Even the Rich Are Treating Their Houses Like Piggy Banks

n recent years, millions of Americans looked at their houses and saw big, fat piggy banks. And it occurred to them to take out big, fat new mortgages.

Few did it on the scale of Ronald Burkle.

Mr. Burkle, the grocery-store billionaire, has $56 million in loans against two houses, including $9 million added last year. One is his iconic Beverly Hills mansion, "Green Acres," a 44-room Italian Renaissance palazzo built in the 1920s by silent-film star Harold Lloyd that more recently was a favorite overnight rest stop for Mr. Burkle's buddy, Bill Clinton.

Mr. Burkle declined to say how he is using the money. There is no indication he needs it to pay the water bill.

Traditionally, the super-rich didn't really bother with mortgages. Home loans were for people who carry lunch buckets, not captains of industry.

That changed in the boom years -- and it is still going on. Recent big-time home borrowers include fashion entrepreneurs, hedge-fund titans and baseball-team magnates.

Home loans "are a really good source of cheap capital," says Robert Maguire, a real-estate tycoon who built some of the tallest officer towers in L.A. He has borrowed some $50 million against several properties, including his beach house, which features huge picture windows framing the Pacific near Santa Barbara, Calif.

He has been raising money with an eye toward regaining control of his property firm, Maguire Properties Inc., which he lost during the real-estate bust. Even as he borrows against his beach retreat, Mr. Maguire is trying to sell it for $29 million.

By hocking the house, so to speak, he and others say they are simply borrowing low in hopes of investing in something they believe will yield a high return.
