What evidence do you have that it won't?
Listen, I base my concerns on human nature. Not some rendering or blueprint where everything is perfect. How much do you wanna bet than when this building was built:

that they envisioned a cool urban place to live, great for up and comers. Yeah, so how did it turn out in reality?!
There's nothing inherently wrong with an 8 plex. But an 8 plex, in a neighbourhood with schools and amenities for families should at least have 4 of those units at 3 bed, two bath. And the 8 plex itself should NOT be on a lot where it barely fits, forcing homes to be so tiny, it makes it so people (who have the means) to want to eventually leave for something bigger, leaving the small, tiny apartments, clad in cheap plastic siding to people without the means. So, in 40 years, as the eigh-plex starts to age, it will be more disadvantaged that will take up residence, turning it into a rooming house.
