Hello, expats!

I am planning a move to Buenos Aires within the next year or so. I'm planning on making this temporary - 6 months or so, and we'll see where it goes after that.

My plan is to stay put in BA for about 6 months, and then spend a month or so travelling to a few other countries in South America.

I've read that tourist visas can be renewed after 90 days, purely by leaving the country and re-entering. Is this true? Also, can anyone give me any advice on living costs in Buenos Aires? What to expect in terms of costs of apartments, general living expenses, etc?

I have so, so many questions, and am looking forward to all the advice folks are willing to give. Thanks!!
