Generally real estate closings take place in either a bank, or a hired room at the colegio de escribanos (kind of the notary society).
Wired money from the USA to a bank will be rolled out on a cart in US dollars, run thru a counting machine, then placed on the table and divided into various stacks, which then get shoved, like poker chips, to the various players. If there is a realtor, they will get one stack. Your escribano will usually get one stack for their fee, the sellers representative will get one stack for unpaid taxes and utilities, and, occasionally a loan, and then, the seller will get a stack.
At this point, its not uncommon for the seller to want pesos for some or all of their payment- another run thru the counting machine, another bigger stack of bills.
It is, literally, Napoleanic.
I would not count on election results to alter Argentines basic feelings about real estate.
With no mortgages, and no real way to seize property for lack of payment of taxes or utilities, there is no motivation for Argentines to lower real estate prices, regardless of the economy. Contrary to many societies, Argentinians often will take properties off the market if prices fall too much, and just wait it out, sometimes for generations.
To own property in Argentina, you have to WANT to be here, or else the vagaries and complications are probably too much. Its not easy. It can be quite fufilling to live here, but its not for the quick speculator, or the weak of heart.
Generally transaction costs of buying and selling are higher than in the US or other countries, but because ownership can often be over multiple generations, the amortisation times are assumed to be longer.
I know many people who live in apartments their grandparents bought, or who live off rents from properties inherited from relatives long dead.
