Ghislaine Maxwell has at least 15 separate bank accounts with a total of $28 million that funded her jet-set lifestyle.
She did that even as she was under investigation as an accomplice of Jeffrey Epstein.
The British socialite was yesterday arrested on sex trafficking charges at a luxury property in New Hampshire in the US.
She had been hiding out with three passports and "large sums of money" in savings.
Maxwell bought the $1.44 million home in cash and is said to have been living like a "movie star".
Aerial photos released by the FBI show the four-bedroom house in the middle of a large forest in the Bradford area, The Sun reports.
Maxwell has previously denied any wrongdoing in her association with Epstein.
A neighbour said: "Very few people saw her – I think most assumed she was a celebrity, as she was very low-key.
"She had the means to buy the house and not go outside very often.
"She seemed to have at least one person in particular who would do things for her. We would see him driving about."
The secluded home is described in a listing as an "amazing retreat for the nature lover who also wants total privacy".
It has features including a floor-to-ceiling fireplace, a "spectacular chandelier" and a "large master bath with soaking tub".
A British man had approached real estate agents about the property, saying he had recently sold his tech company and was looking for a new place in the US.
One of the brokers told the Daily Beast: "They said they didn't want her name known, so I thought it must be a movie star.
"She wanted to know what the flight patterns were over the house, which was very strange."
Details of Maxwell's wealthy lifestyle were laid out in a 10-page detention memo after she was arrested and taken to jail.
Prosecutors claimed her huge fortune gave her an "extraordinary incentive to flee" as well as the means and money to do so.
She had made at least 15 international flights in the past three years to locations including the UK, Japan, and Qatar, the court papers claimed.
Investigators linked 15 different bank accounts to Maxwell, with balances of up to a total of $28 million, with other accounts in foreign countries containing more than $1.44 million.
Money frequently flowed in and out of her accounts and the current balance is not stated in court papers.
Maxwell is also said to have pocketed around $21 million on a sale of an unidentified residence in New York City in 2016.
Prosecutors said Maxwell had gone to great lengths to conceal her whereabouts and had been hiding out mostly in New England, in the US.
Court documents said: "In particular, the defendant has effectively been in hiding for approximately a year, since an indictment against Epstein was unsealed in July 2019."
She has also moved locations at least twice, switched her phone number - registered under the name "G Max" - and email address and ordered packages under a different name.
The court papers add: "She has no children, does not reside with any immediate family members, and does not appear to have any employment that would require her to remain in the United States.
"Nor does she appear to have any permanent ties to any particular location in the United States."
Her 156-acre property was bought all in cash in December 2019 by Granite Realty LLC – a secretive firm set up specifically for the purchase.
According to official documents, the manager of Granite is top Boston lawyer Jeffrey W Roberts.
