Martínez
The commercial heart of San Isidro partido: Unicenter and the Santa Fe–Alvear shopping axis, a river edge of clubs and parks, and wide residential streets of houses in between.

Martínez at a glance
Deep lots, old trees and houses with pools behind the walls — this is where a lot of relocating families end up, usually within a few blocks of a school. The center around the station holds the shops, the cafés and the odd bar; past it the streets go quiet by ten. Everyone drives: to school, to the supermarket, to the clubs by the river. It is comfortable and slightly sealed, and that is the point for the people who choose it.
Families who want the house, the garden, the school and the train, and will own a car.
Unicenter and the Panamericana are the other half of the name — malls, traffic, towers — and the family-house stock is thin and listed in dollars.

Good
median barrio
The overall read is an even weighting of the 11 marks we have for this locality — a starting point, not a verdict. Of our six lenses it ranks highest under “With kids”. Safety is not listed: it is not scored outside the city and is left out of fit; the partido comparison is below. Cost value stands on the partido's asking sale price per m², as no rent is quoted for the locality. Culture counts the cultural centres, theatres, museums and cinemas on the national cultural map; the clubs that carry the social life here are listed under Sports clubs, not in this mark. The tick is the median of the 48 barrios. Eight marks are computed from public data and four are our read; what goes into each is on how we score.
What it costs
average asking prices · Aug 2026Asking rents here rose 29.4% year on year in pesos, per the same index. Studios and two-bedrooms are not published for the suburbs; houses, the usual Zona Norte family rental, are listed in dollars and have no index at all. The province allows a tenant-side agency fee (about one month), which the city does not — see below. Figures are averages of asking prices on one listings portal, not of signed contracts — Zonaprop Index (GBA Norte report), from Zonaprop listings, August 2026 (two-ambientes (one-bedroom) apartment, 50 m² covered); the city reference is the Zonaprop Index, CABA report, August 2026. Converted at the Banco Central de la República Argentina (BCRA, Argentina’s central bank) retail seller rate, August 2026 average. The barrio pages use a different series (the city statistics office, 43 m² base), so compare like with like.
Reported robbery & theft · partido level
reported crimes · 202510.2 reported robberies and thefts per 1,000 residents of San Isidro partido — ranked 10 of 24 Greater Buenos Aires partidos, lowest rate first.
The province publishes crime by municipality, not by locality, so this is the figure for the whole of Partido de San Isidro — 1,541 robberies and 1,481 thefts reported in 2025, against 297,282 residents at the 2022census — and blocks within it differ a great deal. Province-wide reporting runs at about a third of the city's per-resident rate, a recording gap as much as a safety gap, so we do not put the suburbs on the barrios' 1–10 safety scale; the rank among the 24 partidos is the like-for-like comparison. Source: the national crime statistics system (SNIC — Sistema Nacional de Información Criminal, the Ministry of Security's yearly panel), whose city total agrees with the city crime map to within 1% — method and sources.
Getting to the city
rail to Retiro · roadThe Panamericana is the fast way to the city and the airports; Libertador is the scenic one.Train times are rounded from the Mitre line's current Retiro–Tigre running time (about 55 minutes for 28 km) and the Belgrano Norte line's slower diesel service, not read from a timetable; peak frequency on the Tigre branch is roughly every 15 minutes. Check the operator (Trenes Argentinos) before you commit to a commute.
Living in the province, not the city
what changes at the General PazIn the city (CABA — Ciudad Autónoma de Buenos Aires, the capital district) a residential tenant lawfully owes the real-estate agency nothing; Ley 5859, the city's fee law, puts the commission on the landlord. In the Province of Buenos Aires (PBA), which includes all of Zona Norte, a tenant-side commission is legal and customary — budget roughly one month's rent on top of the deposit.
The province charges its own stamp tax on the deed (about 2%) and on a taxed boleto (the preliminary sale contract, about 1.2%), and it keeps an inheritance and gift tax that the city does not have — which matters for whose name goes on the deed. Plan on roughly 4–7% of the price in closing costs for a Zona Norte cash purchase.
The belt from La Lucila to Nordelta holds many of the largest English-language and bilingual schools in the country, and the private sanatorios of San Isidro plus the Austral hospital in Pilar serve the whole corridor. Municipal public hospitals (the Hospital Central in San Isidro, for one) replace the city's network.
Where the city has the café, the plaza and the cultural center, Zona Norte has the club: a member-owned sports and social institution — rugby and hockey pitches, boat sheds, tennis, pools, a restaurant — that families join as families and keep for generations. Children's afternoons, the weekend and most adult friendships are organised around it, and for a relocating family it is the main way in that is not the school. The Culture mark counts museums and venues, not clubs; each locality page lists its clubs and how joining works under Sports clubs.
Your address decides which municipal office, provincial registry office and police station you deal with, and which school districts you fall into. Moving across the General Paz mid-residency means re-doing address paperwork — plan the move once.
A locality is half the decision. The other half is the lease or the deed — the agency fee the province allows, the guarantee, the up-front cash, the contract terms — and that part we walk through with you.
