SUPPORTING “Monster Mom” Casey Anthony has left her parents flat broke, sources say, and now they’re about to lose their home!

George and Cindy Anthony have been foot­ing Casey’s bills ever since she was arrested for the 2008 murder of her 2-year-old daughter Caylee. Casey was eventually acquitted in a sensational trial that riv­eted the nation. But now the Anthonys are both out of work, and a mortgage company has started foreclosure pro­ceedings on their Orlando, Fla., home.

“Being on the run is not cheap,” a source told The ENQUIRER. “Casey can’t get a job, but she needs money for rent and security guards.

“George and Cindy have been supporting her, but now they’re flat broke and about to be thrown in the street. They’ve had huge arguments over how much Casey is costing them, and they’re talking about washing their hands of her forever.”

Another insider told The ENQUIRER: “Casey has put her parents in the poorhouse.

“Neither Cindy nor George work. He’s been earning some money by making wagons for kids and selling them out of their home.”

It’s not the first time the Anthonys have landed in financial hot water. Back in 2010, a foreclosure suit filed by Bank of Amer­ica was voluntarily dismissed. Capital One Bank went after Cindy, 55, for non-payment of a $10,885 credit card bill, but that case was also dismissed.

Now Nationstar Mortgage wants to foreclose on the Anthonys’ home at 4937 Hopespring Drive, claiming they owe more than $128,000 and haven’t made a mortgage payment in nearly three years. The property was the scene of chaos for years as screaming, sign-toting protes­tors – convinced Casey had murdered her daughter – gathered to demand justice for little Caylee.

Casey, 27, is struggling with her own financial woes. She declared bankruptcy in January, claiming she owed more than $792,000, mostly for attorney fees, but had only $1,500.

She also faces defamation lawsuits filed by Zenaida Fernandez-Gonzalez, after Casey claimed to have left Caylee with a woman by that name, and Roy Kronk, the former meter reader who discovered Caylee’s body.

Meanwhile, it appears that neighbors are running out of patience with Cindy and 62-year-old George.

“When the neighborhood association held its annual garage sale, George trucked in stuff from other relatives to sell,” noted the insider. “But the sale is supposed to be for residents’ items only, and there was a lot of grumbling.

“The homeowners’ association is also angry be­cause the Anthonys haven’t paid their dues in years.

“We’d all like to see them go. As neighbors, they’ve been a nightmare. Nobody here speaks to them any­more. If they get thrown out of their house, I’d say good riddance!”
