IP,
More power to you if you can have your fun in an economically way in Sampa. But do keep in mind that there are people at different stages in their life, at different financial levels as well and that there are no one way to do things. I'm at a stage where I value my time more than money. Money comes and goes and can be made relatively easily speaking, while every minute that passes by is gone for ever and no one, not even the wealthiest person in the universe can buy that minute back again. When I gave that so called high figure, it was based on me or someone like me, wanting to stay in the best part of town, near the action like in Itaim Bibi, Jardims or even Morumbi (in case of SP) and that my friend, is going to cost you accordingly. There is no way in hell you'd be able to find a good crib in these areas under at the very least $2k/month, even more so as a gringo on a short term.
Now, looking back at my initial post in the other thread about having a budget of $5-8k/month in SP to have a good time may have been a bit high for the average reader of this forum. I give you that and I acknowledget that it was a mistake on my part and that I should have given a figure in line with the average poster in here. For the average reader of this forum, I'd guess that a realistic/reasonable budget to have a good time in SP for a month to be at around $2-4K. Sure a Brasilian might need a lot less but as a tourist in town, he'd want to have his fun without worrying too much about spending, hence the $2-4k figure for a younger buck in SP may be a more accurate figure. So my bad.
The example of your friend that you cite is exactly what I'm saying: they are able to get those deals because a) they live there full time and b) perhaps even more importantly, that they're brasilian. Even your own example of getting a good deal in Miami, $500 that's mainly because you live there. Now, try getting a similar deal on a 1 month stint and I'll bet you anything that you or anyone else won't be able to pull that off. Can a foreigner there for a month get the same apart as you who will be commiting to a longer term contract for 500/month? Can you, as a short timer gringo, get a 2 bedroom house 2 blocks from Copacabana beach in Rio like your brasilian friend who lives there full time? for what was it? $400 per month for one month? I highly highly doubt that.
Look, I'm not trying to diss you or anything, absolutely not, and quite the opposite. More power to you once again for getting those deals and for having your fun in an economical way. Can Sampa be done in a cheap way? Absolutely. Can aparts/rooms be found for $1K/month or less? Yes again. Now, will these be in the best areas of town? In 99% of the time, no, unless we're talking about a local who commits to a long term contract, not some joe shmoe gringo who's just passing in town for a couple of weeks or at month a most. This is the point that seems that you're having a hard time grasping and realizing. Also that there are people out there who are willing to pay for the convenience and comfort to be in the best part of town and that will take considerably more than 1k/month. And there is nothing ABSURD about paying fair value/market value for the high end stuff for people who appreciate them, want them and can afford them.
