Without going into a discussion on if buying RE in Argentina is a good investment or not... I think its pertinent to state that this article is a sales pitch from a person that has a Real Estate Consultancy Service.

Yes, this is a turn-key sort of option to purchase real estate here... but make sure to read the fine print and figure out what your transaction costs will be. Transaction costs in Argentina are not small... and foreign based buyers are easy targets for over-priced services and expenses related to an apartment purchase.

I dont know the company mentioned in this article and am in no way passing judgement on their services, but I will say that its wise to shop around, ask for detailed estimates and be well informed of the different options you have before you decide to pull the trigger.
