The 'I'm Every Woman' singer - who is currently divorcing husband Bobby Brown after 14 years of marriage - still has the huge sum to pay off on her $5.6 million New York home.
Mortgage Electronic Registration systems, which hold the signer's mortgage, have said the payment is likely to come from a sale rather than a foreclosure.
A spokesman for the company told the New York Post newspaper: "There are people interested." Whitney - who has overcome her addictions to drink and drugs - has not commented on the possible sale yet.
She filed for divorce on October 16 and has requested custody of the couple's daughter Bobbi Kristina, 13.
Whitney has also asked for any property litigation to be postponed until a later date.
