A REAL-life "house of horrors" where police say a couple tortured and abused most of their 13 children has gone on sale.

David and Louise Turpin are said to kept their kids in cages, fed them mouldy food, whipped them with a belt, and even strangled them for watching a Justin Bieber video.

The four-bed house in Perris, which is about 70 miles east of Los Angeles, went on the market Saturday with an auction value of around £280,000.

The notorious property is listed as being in "fair condition", but there is no mention of what allegedly took place withing its walls, The Press-Enterprise reported.

Everything inside the bugalow was said to be normal - even though at the time of the couple's arrest, detectives described the home as filthy and smelly.

Estate agent Hudson and Marshall said it now plans to add details in the description so any potential buyers know its infamous history.

While local law does require estate agents reveal any deaths that took place within three years of the home being listed - there are no current regulations for lesser crimes.

The Turpins have pleaded not guilty to torture, child abuse, and perjury charges that could carry a life sentence.

The couple - who are both in custody - were arrested in January when a daughter escaped from the family's home and alerted the police.

Cops later claimed the kids had stunted growth and wasted muscles and described them as being beaten, starved and kept in cages.

A statement from the Riverside County Sheriff's Office said: "Deputies located what they believed to be 12 children inside the house, but were shocked to discover that seven of them were actually adults.

"The victims appeared to be malnourished and very dirty."

Pictures, later made public, showed an unkempt garden, dirty carpets and doors with scratches on.

The siblings range from two years old to 29 years old.

Child Protective Services (CPS) and Adult Protective Services (APS) were called in and the siblings were given food and drink after they claimed to be starving.

The six children were transported to the Riverside University Hospital System (RUHS) for medical examinations and admitted for treatment.

The seven adult children were taken to Corona Regional Medical Centre for an examination and treatment.

David Turpin's parents, James and Betty Turpin, of West Virginia, told ABC News they were "surprised and shocked" at the allegations.

Neighbours told local media they had no idea there were children in the house, while others said they only saw them at night.

Others claimed they saw them rummaging through bins for food.
