Los Angeles  - The family of the woman who gave birth to octuplets may soon find itself on the street after failing to pay the mortgage on its home for almost a year, according to a default notice filed with local authorities.

The Los Angeles Times reported Thursday that Angela Suleman, the grandmother of Nadya Suleman's 14 young children, was 23,324 dollars in arrears on the Los Angeles area home that the family lives in.

The default notice was filed on February 9. Suleman bought the house in March 2006 for 605,000 dollars with a loan of 453,750 dollars.

The new information could increase the public backlash against Nadya Suleman, who is single and unemployed and who has already come in for scathing criticism over her fixation on having children even though she has no apparent way to support them.

Even her plans to cash in on the sensational birth of eight babies via media interviews and book deals appear to be coming unstuck. The public relations firm that was helping her withdrew its support last week in the aftermath of a torrent of threats, while her book agent also decided not to handle her story.

However Us magazine said that Suleman had managed to parlay her extraordinary story into cash and has received 100,000 dollars from US tabloids and 227,000 dollars from British tabloids.

Angela Suleman reportedly received 40,000 dollars for an online video interview in which she showed the inside of the cramped home and blasted her daughter's actions as "unconscionable."

News of the Suleman's mortgage troubles came to light a day after US president Barack Obama extended a 75-billion-dollar government lifeline to homeowners struggling to pay their mortgages. The default or foreclosure on more than 3 million US mortgages is at the heart of the cascading global economic crisis. But the new lifeline is not intended for people who speculated in the housing market. (dpa)
