Is Octomom about to become homeless?

Nadya "Octomom" Suleman's house goes up for auction at 9 a.m. on Monday morning.

The family's four-bedroom, three-bath La Habra, Calif. home will go to the highest bidder at 9 a.m. at City Hall in Orange. She has lived in the four bedroom house with her 14 children since 2009, but has reportedly fallen behind on her rent payments.

Orange County businessman Amer Haddadin, who sold Suleman's father the four-bedroom home that's about to be auctioned, said he's owed $483,000, including 11 months of unpaid rent and a $450,000 note that Suleman never paid off. He says he has no sympathy for her, adding her actions led his mortgage holder to foreclose on him and destroyed his credit.

"She's not only using the system, she's abusing the system," Haddadin said.

With Suleman on the verge of losing her home and declaring bankruptcy this week with total debts as high as $1 million to everyone from her parents to her baby sitters to the water company, the Octomom Odyssey seems headed for darker days.

Beyond the fascination with her public foibles, such as posing topless in an obscure British magazine and talk of a solo porn film, is the very real concern about the welfare of her octuplets and six older children — all borne from her zeal for in vitro fertilization.

Three of her six older children have disabilities for which she receives government financial support, Suleman has said. One is autistic, another has attention deficit hyperactivity disorder, and the third a speech impediment. The older children range in age from 5 to 10.

One thing that keeps driving interest in her is whether authorities should step in and take the children.

Child welfare officials visited her La Habra home last week following a complaint that her children were living in squalor. They took no action, and Orange County Social Services spokeswoman Terry Lynn Fisher said Thursday the law prevents her from even confirming or denying the visit.

Speaking in general terms, however, Fisher said it's not illegal for families to be homeless, to live in dirty homes or even in their cars, as long as that doesn't place their children in danger.

If the Suleman saga is wrapping up, it would mark a sad end to something that, if only briefly, once seemed to some like the feel-good story of the year.

That was on Jan. 26, 2009, when Suleman's octuplets were born at a Southern California hospital and made medical history when they all survived. In the days that followed, she was reportedly showered with offers for book and movie deals, reality TV shows and a mountain of free baby stuff.

Things changed quickly, however, after it was learned that Octomom was also Single Mom and Welfare Mom. And that she already had six children under the age of 8 and was living on a combination of welfare checks, food stamps, student loans and her parents' largesse.

The movie, book and TV deals faded, and Suleman, now 36, turned to increasingly bizarre means of making money.

"Clients have to be willing to accept advice from those who have the experience and expertise to provide for them," Joann Killeen, Suleman's first publicist, said Wednesday. "I think it's obvious why she's gone through so many managers and attorneys and professional staff in the three years she's been Octomom. Clients who don't listen don't make good clients."

Lately, Suleman has made money posing topless for the British magazine and has a possible porn deal in the works, although the latter comes with a catch. She had said she'll only do it if, to put it delicately, she is the only one being filmed. It would be what the industry calls a solo tape.

That led Vivid Entertainment Group co-founder Steven Hirsch, who once offered Suleman $1 million to do a porn film, to say he doubts his company would be interested in working with her in the future.

"I'm not sure that after that's released that it would make sense," he said.
