The next question I have is - is there any difference between buying land with a CDI versus a CUIL with regards to selling it down the line?
I hear it can be quite difficult selling a property as a foreigner. If you have a DNI maybe it's better than having a CDI? And maybe it is even better if you have citizenship?
I wasn't able to do the CDI in the end because my visa is expired. So I'm starting residency process. I am told that at the end of my first appointment with migraciones, after I have presented all the things they need for me to apply for the rentista visa, then they will give me a piece of paper with a CUIL number. And then supposedly in a month I will have a temporary DNI. But that with this CUIL number I get the day of the first appointment, I can use it to buy land.
You either buy property (an apartment, house, or land with or without a dwelling) with a DNI or a CDI. The requirement to have a CUIT or CUIL to buy property may be new, but it can only apply to those who already have a DNI.
Are you sure that if you have a DNI you also need a CUIL to buy property or that you will get the CUIL from migraciones?
If you have residency in Argentina and have a DNI, you will be able to get a CUIL issued by ANSES if you are employed. If you are not employed in Argentina you will be able to get a CUIT issued by AFIP.
Recently someone posted about receiving a CUIM from migraciones but I never heard of it before reading the post. Perhaps that's what you will get the day of the first appointment (as opposed to a CUIL).
If, in the future, your visa expires and you sell as a non resident, you will have to provide documentation which shows how much time you spent in Argentina and, unless the utility consumption (for a property that includes a dwelling) drops to near zero levels when you are out of the country, there will be taxes due on assumed rents (unless you have already declared the rental income and paid taxes on it). If you buy "land" without a dwelling this would obviously not apply unless you build a home on the land.
In short, it really doesn't make much difference if you buy as a resident or not, but it makes a difference when you sell and there shouldn't be any difference between selling property as a resident with a DNI or a citizen.
The first time I bought property in Argentina I had a precaria and a CDI but not CUIT or CUIL. Selling a few years later as a resident was actually quite simple. I welcome corrections and updates to this information as I haven't bought or sold in almost five years, but I have tried to keep up to date as I have land for sale where I now live.
