26 after i finished uni and moved interstate.

23 when I left for university, though by that point I had already been working for a few years as a school assistant and a substitute teacher.

18, when I left for university in another city. I still went home for the weekends for a couple years yet I stayed there when I started working.

My sister moved out when she was 16 or 17 to live with a few friends in a house they rented in my home town.

My parents moved out from our home when I was 21 so technically I didn't move out and the cool thing is that I had to pay no rent.

Still live with my folks, should be moving out soon after I graduate university this semester. So...21 in the future!

18, it was a rough period for various reasons. Silver lining is made me independent person I am today.

I know it will feels weird but I left my family´s home at 35. But there´s a good reason for that:

In my country, most people only leave their family´s home when they get married OR if they need to move to a different town/city for a good job.

The reason is that housing is extremely expensive in my country, so instead of spending our hard-earned low money on rents, people prefer just to stick to their families and use that money to provide a less strict life for everyone.  Also, culturally we are alwaysvery  close to our families.

Buying a house or apartment here may demand 20+ years debt, and only if you are able to get a job that pays about 50%+ above the average income. This is a little less hard if you get into that as a couple, so most people are only able to get their own houses after marrying. Many couples, sadly, are not able to do that and may forever live paying rents, due to the costs of the city where they live in. 

I never got married and I did not wanted to waste money on rents, so I stayed with my family until I could get a job with a salary good enough to get into that debt alone and then finally, buy an apartment. I´m still a looooong way to finish the debt, though.

Good thing is, during this time, I could help my family a lot, as we shared all bills and expenses, everyone was able to save some money.

18 when I was out of the country for a couple years. Moved back in for 6 months when I was let go at work. Moved back out on my own at 26 once I found new stable employment

I was 28. Moved out when got married.

I dont think houses are that expensive in Brazil as an average. The problem is that salaries are low and interest rates for morgages are very high.
