i went to an auction (remate) to check out an apartment being sold in Alto palermo, its crazy when you get there, its like a mafia movie. full of super cheesy, greasy looking men. when u sit down they come and sit on each side of you with their business card and they tell you to talk to them after the auction. You have no chance of even trying to make an offer. they are all working together and after the auction is done they all come up to anyone that isn't part of their mafia and tell you to call them if you want to buy the apartment off of them.
one guy told me, that he handles the apartments, his brother used cars and his uncle, the houses.
100% mafia owned business unfortunately!
