If you search for "quintas" ("residential farms" in English) you will find many others.
Here's one EN EXALTACIÓN DE LA CRUZ, PARADA ROBLES, BARRIO EL ZORZAL with almost 3000 metes sq. for exactly $100,000.

It was included in a search for quintas in Gran Buenos Aires - Zona Norte.
I am not familiar with the Barrio El Zorzal. Pilar is probably more desirable.
Either way, you run the risk of being surrounded by Christians.
