I've been watching the prices of various apartments for years; one down in Villa Crespo has been listed at the exact same price for over seven years. And it's not like it's some kooky dueno listing it; it's through a big RE company here. At some point, wouldn't the agent drop the listing if the seller won't lower the price?
Meanwhile, the place I had my eye on disappeared from zonaprop, but the sign on the balcony stayed up. I discovered the price was raised by the agent from $125 to $170. It had been listed for the lower price for months without selling, then they raise the price 40%? It's a real head-scratcher.
