Peter Madoff's Old Westbury estate on Long Island has been listed by the U.S. Marshals Service.
Madoff, who pleaded guilty last year to falsifying documents and lying to regulators as part of his brother's Ponzi scheme, was sentenced to 10 years in prison.
He was ordered to forfeit his family's assets as part of the plea deal.
The 1935 mansion has five bedrooms and five bathrooms. The property also boasts a tennis court, swimming pool and pool house.
The U.S. Marshals Service has already sold Peter Madoff's Park Avenue apartment for $4.6 million.
The proceeds are going to victims of the Ponzi scheme.
