Usher is finally making good on his threats to evict ex-wife Tameka Raymond from the house she still calls home ... officially listing his Georgia mansion for a cool $3.2 million.
Usher bought the 12,544 square-foot pad in 2007 -- while still married to Tameka -- for $3 million. He officially listed the digs last week.
TMZ broke the story ... Usher's ex has continued to live in the house as part of their 2009 divorce agreement -- but in September, Usher made it clear he was planning to sell ... and Tameka would be kicked to the curb.
As for the house, it's pretty huge ... 6 bedrooms, 7 baths, 10-foot ceilings, massive pool, in-home gym, 4 fireplaces, a library, and a NASA launch pad. Kidding ... NASA doesn't have funding for this place.
