Another LL (of one property) here. Don't think I'll be converting anyone to my LLing ways, but do want to weigh in as the aggro towards Nutella particularly seems to warrant a response.
"It is about working smart. It's also about saying no to holidays and smart phones and going out when your young. It's about being 18 and saying no, I won't go out, I'll save this £30 and it will go towards a deposit when I'm 30."
^^ This sums it up for me.
Like most people, I didn't wake up one day to find a deposit for my home/BTL in my bank account. I lived in a dodgy shared flat for four years with the aim of saving most of my salary, took plenty of overtime at work, took a job that was more "City" than I would have liked, delayed having children. When I bought my flat it didn't tick many boxes of garden/room size/ceiling height/city centre - it was good enough, and I was realistic about how far my money would stretch.
I was able to buy at 29, in SE London. (No parental help, no lottery win, no conveniently deceased rellies.) Most of my work colleagues were pissing their salaries away down the pub and on fancy holidays.
If you wake up aged 30, with a couple of kids, in a low-paying job, and think, "Gee, better buy my own place!" then, yes, it will take a good long while to save up. That would be the case even if the property market in the UK was regulated more heavily.
