Argentina regularly prevents US dollars from leaving the country so you might not be able to get your money out if you sell.Because of this, very few international investors buy in Argentina and only the wealthy (the minority) can afford to buy nice properties, so your odds at a capital gain are much lower than normal and you might have an issue selling at any decent price, let alone getting the dollars out of the country.And yes, sadly, the economy is a basket case and corruption is very high.There are so many other great countries in Latin America where you can make a smart real estate investment.

If it's a high-end wealthy neighborhood (think Los Altos, Menlo Park, Palo Alto) where all the main houses are giant, maybe the potential buyers would just think of an ADU as a bonus, but not as something they want to pay a lot of $$ for, since they are most likely not going to use the ADU as a rental, but more like a guest house or an office.However, if it's in a neighborhood where most buyers are younger folks who have young kids and elderly parents (think Santa Clara, San Jose, Fremont, etc.), then ADU is very appropriate as child care and caring for elderly parents are big & real needs among this demographic.
