> how many drunken ragers can a 1 bedroom apartment really handle?

Depends on how they were built. For some college halls in the UK, maybe a few hundred years worth?

They aren’t failing structurally, they are just in a perpetually ugly state because a landlord doesn’t care about keeping a property attractive that students will abuse.

So you end up with worn out carpet, paint flaking, broken door handles, etc etc.

That’s why there is a different much smaller but much better pool of properties for people willing to do an 18+ month lease.
