Well, since I already own a place in Buenos Aires, and have no intention of selling in the next 10 to 15 years, some of this is less relevant to me-
But-
A "bargain" in real estate is, for most of us, kind of meaningless.
Unless you are Ted Turner, and frequently buy 10,000 acre ranches, most of us will buy one or two pieces of real estate in any given ten year period- so shopping for bargains in suburban Atlanta, or how cheap a concrete block tract house is in Kendall Florida is, this is irrelevant to most people.
If you want to live in Athens or Kendall, then, shopping for bargains there is great. But I assume most of the people who post and read here do so because they want to live in Buenos Aires, Argentina.
Not because they are constantly flitting around the globe, snapping up "bargains" in real estate wherever and whenever one occurs.
Me, I would rather spend the next ten years in a dentist's chair than live in rural Georgia or Alabama. So whether there are bargains there is about as irrelevant to my life as you can possibly get.
I give the posters here the benefit of the doubt- and assume if they are hip, knowledgable, and discerning enough to realize what a great city Buenos Aires is, they would want to live in similar cities in the USA, or Europe, or Asia- not in one horse redneck towns in the south, or in Albania, or Kinshasha, both of which I hear are full of great bargains.
And right now, in the USA, in cities that are comparable to Buenos Aires in size, culture, charm, and interest, like San Francisco, Seattle, Austin, Boston, NYC, or in cities in Europe like Barcelona, Torino, Brussels, or Berlin- prices in all those places, for equivalent, apples to apples apartments, are all still way higher than in Recoleta or even Chacarita.
Sure, if you want to compare an art deco mansion off Riviadavia like the one some friends of mine bought a couple years ago for under 200k, with a particle board double wide in east Texas, it costs more. Now compare that same house to a similar age, quality, and style one in Brussels.
Frankly, it is to laugh.
Absolutely, prices are down a bit. Absolutely, the manic expat buying boom of two years ago has slacked off. And, Absolutely, Buenos Aires in NOT Barcelona or Paris. But its still about 1/3 or less of the price for real equivalent housing.
