Short answer
Many Argentine real estate listings, especially in Buenos Aires and premium lifestyle regions, are quoted in USD. That does not mean every part of the transaction is dollar-based. Taxes, invoices, rental registrations, and registry values can require peso conversion or local reporting.
Why USD matters
US and Canadian buyers compare Argentina against dollar assets. USD pricing helps with underwriting, but buyers should confirm the actual settlement method, where funds are delivered, and how the escritura records the transaction.
Market reference
For Buenos Aires apartments, public market indices such as Zonaprop track average values in USD per square meter. Buyers should still compare micro-location, building age, expenses, and actual closing comparables.
