A small practical point for those paid in dollars: argeiCanuck's 41% on rent is the part nobody controls, but the exchange house you use is something you do control. On 13 Nov the houses listed on ArgHub paid 154,000 to 155,700 pesos for 100 USD in cash, so the best and the eighth house differ by about 1.1%. That is small next to inflation, but it costs nothing to compare quotes before changing, and the final amount is always confirmed by the house itself. Disclosure: I work on ArgHub, which lists these houses.
