should you buy you´ll probably see a nice capital appreciation within the next 5/10 years
but more than Villa Urquiza, I would choose Saavedra/Coghlan, it is greener and closest to General Paz
Add to this, that it has had the highest construction requests during the last quarter, according to a La Nación article published a fortnight ago.
Irsa, or one of the other argentina megaconstructors has started the construction of what will be the biggest shopping mall in Latam, where the Phillips factory was. That will attract, restaurants, more construction etc.
It has excellent connections to the outskirts and the charm of living in a neighbourhood with low houses and not that busy, I myself was looking for something to buy over there, and should you have the money to invest in plots of land, I myself consider it "the place".
Take a look at Tetris on Toribios Achaval Page, they are selling new PH (WITHOUT EXPENSES THAT ARE GOING TO HELL) that seem quite interesting. They are in fact within the limit within coughlan/Saavedra but this is a nice neighbourhood behind belgrano R
The selling price starts at usd36,000, not bad, if you are planning to stay several years maybe you end up paying sthg similar.
Good luck with your search
