Don't buy real estate in Buenos Aires without knowing all of the laws, ins and outs and all the possible pitfalls.

It will describe the process to buy. I hired
@BuySellBA to help me purchase an apartment in Buenos Aires. I looked at possibly getting a used apartment but everything I looked at needed to be gutted. Almost all the properties unless you are buying a relatively newer apartment needs new kitchen or bathroom. I did not want to go through that process. I bought a penthouse apartment in this
building. My apartment is almost done. The building is all up but they are finishing up with lobby and some of the units.
I used the real price. I looked at some new construction and all of them used the true prices. I also did not have to wire any cash besides the initial offer but that was only $2,000 dollars.
@BuySellBA helped set up so I could just wire in US dollars to a US dollar account and I did not have to deal with cash. On other developments they did not have that structure in place and I would have had to wire in but it was more complicated with capital controls in place by the government. Be careful. As it was explained to me by the company that I hired that it isn't technically legal to wire in cash with cuevas. This government might not care but the next one might. Kind of crazy the capital controls in place so it is a good idea to understand that.
Many sellers are doing this not just to pay less taxes for the sale but most are very private and don't want the government to know what they are doing with their money and also Argentina has wealth taxes on assets you have. Many prefer to just have cash set aside and not have the government know what they have.
Probably a good idea for you to research more. It is much different buying here compared to back home. No you can't open up a bank account here easily. I tried when I was in BA.
@BuySellBA got my CDI number which is a tax ID number that you must have to buy real estate but the bank didn't let me open a bank account with that. They said I needed to have a DNI. I read some reports of people opening an account with CDI but that was after I was there last year. Maybe it is easier now.
