San Isidro vs Béccar vs Martínez vs Acassuso

The pick

Who each one is for, and the catch.

San Isidro

Historic town on the bluff

Pick it ifSettlers, not short stays: people who want a real town with a center and plan to stay years.

The catch'San Isidro' in a listing can mean the partido, which runs to the Panamericana; the town on the hill is a few prime blocks and priced like it.

Béccar

Mixed river town

Pick it ifSt. John's families, and buyers who want San Isidro's river side at a step down.

The catchInland near the Panamericana sits La Cava, one of the zone's largest informal settlements; the river side is a different world and the listings know it.

Martínez

Suburban center

Pick it ifFamilies who want the house, the garden, the school and the train, and will own a car.

The catchUnicenter and the Panamericana are the other half of the name — malls, traffic, towers — and the family-house stock is thin and listed in dollars.

Acassuso

Old money, old trees

Pick it ifPeople who want old San Isidro's quiet without its Sunday visitors.

The catchAlmost nothing comes up for rent; what does is a house, in dollars, through a local agent who already knows the family.

Scores run 1 low to 10 high; “data” means derived from a source, “our read” is our considered opinion. Rents are averages of asking prices — the city statistics office for barrios (43 m² one-bedroom), the Zonaprop index for Zona Norte (50 m²) — converted at each table's bank rate. A missing dimension is left out of fit, never counted as neutral. Methods and every source with its date: how we score.
