That article you posted uses a set of maps as its source, but if you go to the maps they refer to, a lot of cities have changed drastically where there was redlining. Atlanta may not have changed much from the redlined map, but Los Angeles and San Francisco definitely have, and those were the only ones I looked at. Many of the areas that were redlined are full of multimillion dollar SFRs and lots of great shops and commercial properties.
