Kim Zolciak's kiddos are denying the family's Georgia mansion is in foreclosure and heading to the auction block ... claiming it's all a misunderstanding.
The "Real Housewives of Atlanta" star's daughters, Brielle and Ariana Biermann, tried to clear the air Wednesday ... telling photogs at LAX the family is still living in their Alpharetta estate with no plans on moving out.
Brielle and Ariana say all the family's belongings are still in the home and they're not concerned about losing the house ... saying they even slept there before traveling across the country.
