I found a website that says average cost of living in New York (for 1 person) is $3200/month. That's around 40,000 per year. If the electrician is making 80k, that would mean they could save 25k/year after taxes and living expenses. 8 years of work and they would have 200k, enough for a down payment right? And this is assuming they live in new york, one of the most expensive places in the world
