I think the preferred approach these days is create lots of high-paying jobs in close proximity to the slums and wait for gentrification to happen. Makes a bunch of yuppies do the dirty work and take all the risk of displacing communities as tenants while the rents skyrocket. Then when they finally reach the point where they can afford to buy, they'll apply for huge mortgages to buy in the slum they effectively converted into a desirable place. Profit. This is what seemed to play out in The Mission district of SF over the past decade or so.
