Wow, this thread really attracted a lot of attention! I guess that shows how important parking spaces are to people, even if they don't use them. Which is relevant to my scheme, such as it was.
Lots of food for thought here especially people saying I could lose my tenancy. Obviously I don't want to do that.
It's taken quite a lot of effort to work out which spaces are unused but I guess I'm reaping the benefits of that work by finding places to park. Appreciate that the owners of the spaces may well be aware I'm using them but know I'm a resident so aren't challenging me. It doesn't mean they don't care about the spaces at all.
I've decided against this anyway, I don't want to threaten my tenancy.
For those saying get a second job, I would, but it's complicated (isn't it always haha 😥) I work full time but I don't earn much and my daughter is leaving education this year so my universal credit top up stops plus I'll have to find another 25% council tax (out of my arse??) once she's classed as a second adult. Obviously the ideal is to earn enough working full time that I don't need universal credit but well my wage is low. I am shitting myself.
I can't take on a second job because my mum's got dementia so I need to spend the time when I'm not working looking after her. I was just trying to think of ways to earn money that don't involve spending time so I came up with this parking wheeze. But obviously it's pie in the sky and wouldn't work. So back to the drawing board for me.
Thanks everyone for your thoughts.
