The problem with this scenario is that there is an established market price for property. In the neighborhoods of Recoleta and the Palermos apartment selling price ranges from U$2400 to U$3000 / m2 depending on building amenities, view, location within these neighborhoods, property expenses, etc. The very nicest buildings might get a bit more. The sellers who price their property above this (and who are not willing to negotiate to the real price) are not selling. Buyers are not stupid.
