Base and Valuación Fiscal — Why the Opening Price Looks Impossible

Argentina (AR) — civil law.

Nothing on this page describes United States practice. There is no certificate sold to an investor, no administrative sale, and no post-sale redemption window in Argentina. If you arrived carrying US assumptions, read falsos-amigos first.

Base and valuación fiscal

The rule

Under CPCCN art. 566, the opening base for real property is two-thirds of the valuación fiscal. Where no valuation exists, the judge appoints an engineer or architect perito to appraise. Provincial codes follow the same architecture with their own numbers.

The valuación fiscal is set by the provincial `Dirección de Catastro`.

Why the number looks wrong

Argentine cadastral valuations have historically sat far below market value, and periods of high inflation between revaluations widen the gap further. A base is therefore often a small fraction of what the property would fetch in a private sale.

Three consequences follow, and all three are routinely misread:

1. A low base is not a discount. It is a statutory formula applied to a stale input. The court is not offering the property cheaply; it is opening the bidding low. Real price discovery happens in the competition.
2. A low base says nothing about encumbrances or occupancy. Cheap and clean are unrelated questions. See ocupantes and expensas-y-el-adquirente-en-subasta.
3. Currency compounds the confusion. Base figures are stated in pesos (ARS), while Argentine residential property is customarily valued and transacted in US dollars. Comparing a peso base to a dollar market value without converting at the right rate, on the right date, produces nonsense. See moneda-y-pago.

Sin base

If nobody bids at the base, the court may order a further auction at a reduced base or sin base — no minimum at all. This is where genuinely low clearing prices occur. How many attempts are allowed, and by what steps the base is reduced, is provincial and needs_verification.

What to do with the number

Treat the base as the entry ticket, and build your own valuation independently: comparable sales in the barrio, the physical condition you were able to observe at the exhibición, the expensas arrears certificate, the occupancy position, and the full cost stack on top of the hammer price.
