Washington (CNN) Paul Manafort and Rick Gates will stay under house arrest and GPS monitoring for the time being, a federal judge said Monday.

At a hearing in Washington, Judge Amy Berman Jackson said she won't make a decision on both defendants' bail until she receives more information on their financial situation. Once that information is filed, she proposed that pair remain under GPS monitoring, but be allowed to travel in their local area -- the Washington area for Manafort and Richmond, Virginia, for Gates.

Additionally, she proposed they will be prohibited from being near airports and train stations, and will have evening curfews.

Manafort and Gates will next appear in court on December to discuss a trial date. Jackson has previously proposed May 7, 2018 for the trial to start.

The judge's bond ruling is expected before the December court date.

Federal prosecutors from special counsel Robert Mueller's office and Manafort's lawyers tangled throughout the weekend over the former Trump campaign chairman's bail as he awaits a trial on white-collar criminal charges.

Mueller's lawyers also contested whether Manafort's properties are worth what he says they are.

On Saturday, Manafort's lawyers proposed that he be allowed to travel in those three states and Washington and pledged as collateral his properties at Trump Tower and on Baxter Street in New York City and in Palm Beach Gardens, Florida, and $4.5 million in life insurance policies.

In the court filing, Manafort's lawyers estimated that real estate to be worth $8 million, meaning he would be on the hook for $12.5 million in assets if he violated his bail.

The federal prosecutors, however, said they can't tell the properties' actual values, and his Palm Beach Gardens home could be worth a quarter-million dollars less than Manafort claims.

The value of the Trump Tower condo on Fifth Avenue in New York is also a question mark, the federal authorities said. Manafort's lawyers say it's worth $6 million and he has a $3 million mortgage on it. But the government lawyers say they haven't seen a real estimate of the property's value and believe it may be worth only $2.5 million or $2.7 million.

They still contend he's a flight risk, and say his total net worth — which Manafort claims is $28 million — is unclear until he gives them more details.
