18. Moved back in later on (22?) for about a year before moving out for good at 23 or 24.

19 pretty much. I left to go on an lds mission and I technically moved home for like month when I got home... but then I moved out to go to school after 1 month... so I guess you could say 21... but i would say 19.

Comparing  prices with developed countries, yes. But our country has a much smaller average income, what makes housing here proportionally more costly. The average  salary in Brazil last year, was  R$ 2480,00 ( USD 703), while the average rent in a city like São Paulo was R$ 1750,00 ( USD 512 ) and the cheapest apartments in the same city - located on the farthest districts, cost around R$ 140.000 (USD 42.000). Ouch!

Of course, prices may vary a lot depending where you live. In smaller cities, houses are cheaper. I could by a house in a small city for  half the price of my apartment, but I´d have to quit my job and I would never find another one with a similar salary in that city. Most people do that with a plan of opening a small business in mind, but that also requires a lot of money. I personally don´t want to move so far from the state capital yet. Maybe when I´m older and closer to jubilating. 

very late, i were 28, but it was o.k. for me😉

Sadly culturally the family structure of my family (If I wasn't only child or the oldest, I could have branched out), the family stays together (which to be fair I understand in principal, but do not like in practice.)

I might start applying to work outside of this city, so I could be on my own for a bit (Lets say Montreal or Calgary). 

On the bright side, my savings will just get bigger and bigger with only dealing with my own bills.

I moved in with my partner last december at the age of 21 :)

I'm turning 20 next month and I still live with my parents. No big deal for me since I'm still in college, but I plan on moving out once I graduate (I want to work overseas).

Techincally 17, but:
A) I moved in with my sister in Canada (tho she moves out in 2 days!)
B) I still mostly use my parents money (mostly. Outside of school and travel, I think I can pay for everything out of my own pocket)
So not completely independent yet. I'm 20 now btw
