This kind of gentrification is actually pretty awful in my opinion. Pushing out low income people who already live in an area just because you find them "sketchy" is a horrible way to run a city. Why does an area need to be "cleaned up and reclaimed" from the people already living there? Surely they have a right to continue living in the area without being priced out (or evicted, in the case of rooming house tenants)? We have provisions for apartment units to be rebuilt and, if I recall correctly, for the previous tenants to have first dibs on the rebuilt units. The city's poor and precarious should have that right too.
