Serious question. I understand if you cannot afford a single unit, sure. But why would anyone actually want a multi-unit?
People are noisy, smell on occasion, etc. if a city is too crowded, find somewhere else. You’ll be better for moving where you can afford. Moving somewhere just to be in the “hot spot” or something is silly. Go move to a single family residential neighborhood and you’ll be far happier. You can have a garden, put a hole in the wall and expand a room, get a dog.
Beyond personally never wanting to live that he’ll again; I personally would never want a multi-unit home in my neighborhood. I don’t want the density of people. Don’t need the problems that entails, don’t need lower property value. It makes a worse quality of life, that’s why the value drops.
People who want these units want to live in a particular location, but don’t want to pay prices. And the location is more important to them. I get it. That location will be ruined by those homes; at least it will change the dynamics. That’s the unfortunate part.
