Then why did real estate prices skyrocket only in the last few years? Why do they affect multi-family housing equally? I'm paying nearly USD2000 per month for one apartment in a building with dozens. 15 years ago, I paid only USD725 per month for a larger apartment in the same area.

Land scarcity is not the problem. It's a distraction from the problem, no doubt perpetuated by the people causing the problem. Stop letting them deceive you.

And no, there's nothing comfortable about living under the tyrannical whims of a building manager and not being able to let your pets roam outside. That is a dramatic decrease in quality of life, it is not necessary, and it is not acceptable.
