The sad thing is that individual landlords are among the most responsive to tenant needs, while corporate landlords often are sons of Hell who should be Thanos-snapped out of existence.
This is extremely dependent on a lot of factors. When you are an upper-middle class tech worker renting a luxury condo, your landlord will absolutely be responsive and helpful. I've been in those condos and they're great.
But I wasn't always able to afford to live in nice condos. When I lived in a cheap ground-floor unit and my bathroom started spewing feces out of the toilet and bathtub because the building's main sewer line was clogged due to the individual landlord fucking up a DIY fix, my individual landlord decided to ignore my calls because I was being annoying, and then I had to fight them through my local tenancy dispute board to reclaim the money I spent on hiring a plumber over a holiday weekend.
So yeah... it depends.
In my own experience: For corporate landlords, being a poor grad student or a tech worker didn't seem to make a difference; I was still treated like I didn't exist. In several instances there were serious issues with my unit that were affecting my health, and they were ignored. Individual landlords were awesome people -- fast and responsive to issues big and small, and even did things to make my stay better.
Seems that many results vary, but I suspect that when there's no human connection, you'll get a lot of bad stuff going on
Turned our cap for gas was just sitting on pipe. All the gas pipes were hand done (badly) and against code.
So permanent brain and nerve injuries for while family and hundreds of thousands in hospital bills.
Screw them.
Unless you're saying all the plumbing was only finger tight and they never used a wrench, which is just so wrong it didn't even originally cross my mind as what you're saying as done by hand. You're gonna need a good pipe wrench to get your gas connections tight.
