The issue is not really the DNI. Renters must have guarantors - similar to co-signers only the guarantors have tremendous responsibilty. If the renter does not pay the guarantors must pay the rent plus court costs etc. Few foreigners can find guarantors unless they have close friends or employers who will sponsor them. Also leases are for 2 years, no less. I disagree that a 500 dollar rent would necessarily be 500 pesos for an Argentine with good guarantors. Rents in good areas have increased dramatically. As a result, the gap has narrowed. Yes, a foreigner will pay more but not always 3 x more. Also keep in mind if you are a local renter paying in pesos you usually pay all expenses: condo fee, gas, water, electricity and taxes. Not so with temporary rentals. Rosario may have better pensions. What I have seen here is not good - and not always so safe. I agree that you might find cheaper housing in areas farther from the center, Recoleta, Palermo etc. Even in these areas, however, owners will want guarantors. Sometimes, however, you can make a deal and pay the rent in advance for several months or a year without all the legal requirements.
