I was not referring to the overall cost of the real estate- but to the cost of the transaction, including taxes, fees, and so on. I have found that in the USA, my cost, as a percentage of the sales price, is less to close than in Argentina. In my state in the USA, we use an escrow company, no lawyer, and the total additional cost above real estate agent commission is not a lot.
I have purchased a couple of properties in Buenos Aires, and there never was a 21% VAT tax on the total sales price. Most recent was in 2019.
I dont remember what the total cost to buy was, but I know it was under ten percent of total, but a couple of points higher than it was for previous deals in the USA.
