Toni Braxton's Foreclosed Mansion Up For Sale

Braxton took out a loan for the Duluth, GA home back in 2004 for $1.5 million -- but according to the bank, she failed to make at least 10 monthly payment between 2004 and 2010.

As TMZ first reported, the singer filed for Chapter 7 bankruptcy in 2010 -- during which time she tried to save the home from being sold off. It didn't work,

Here's what she's losing ... 11,400 square feet, 6-bedrooms, 6-baths, an acre of land, jacuzzi tub, gourmet kitchen and a library.
