Racial segregation in neighborhoods and housing started to become a real problem during the 1920s and realtors contributed to that.
Some realtors during this time wanted to keep blacks and whites in separate neighborhoods, as some were racist and wanted to continue racial segregation. Some would create high prices so African Americans would not be able to afford homes or purposely sell homes to just white people.
Blockbusting is another way that realtors during the 1920s continued racial segregation in housing and neighborhoods. This was where they would tell white homeowners that minorities would be moving into the neighborhood. This would cause many white homeowners to panic and sell their homes at a low price.
