Facepalm

They're supposed to suck it up, take the first and worst job they manage to plead and grovel for, and stick with it no matter how many health and safety violations you have to ignore, no matter how hard, painful, or tiring it is. If you'd rather die than keep working there, then go die.

If you don't, if you stick to it, if you get enough money to start renting some place, then you suck it up and live in the cheapest dump if you have to, show your gratitude to God, and you do everything in your power to fix it up and make it nice.

And it doesn't matter what state it's in, doesn't matter what needs to be done, doesn't matter what you've been taught or not. Just do the thing. If you prove to be bad at whatever it is, then that's what you are. And if the landlord won't let you do anything? Landlord who? Still your fault. Maybe you shouldn't allow yourself to give off the impression that you're an incompetent craftsman when you ask permission for something so crucial. It is shameful to live in a home out of order and in disrepair. So that's the next step, be ashamed of your condition, until you can afford to be a chooser. Maybe. Unless you'll never earn enough to live somewhere better. Then just stick with it. Live and work in shame of your incompetence.
