Based on Mr. Lindner's offer to pay Walter and his family not to move, it can be inferred that his motivations stem from a desire to prevent racial integration in his neighborhood. Mr. Lindner's payment can be seen as an attempt to maintain the status quo and uphold segregation by trying to convince the African American family to stay away. This suggests that he values racial homogeneity and is willing to go to lengths, including financial compensation, to preserve it.
