I just got done with the process of buying an apartment there. I had the same frustrating experience. What you have to do is stop comparing the experience to the USA. Once I figured out that it is NOTHING like the USA it was much easier. I initially used a realtor that I met from seeing a listing with Zonaprop. She was ok at first but then just seemed to get frustrated with me.
It seems like the realtors here don't have much hustle. They are happy if you know exactly what you're looking for or are just contacting them about a specific listing but I had a falling out with that realtor after I switched the search from older properties to new construction. She got angry because some developers only shared 1% of the commission and she wanted me to make up the difference. I didn't think I should have to do that as the developers were still charging me 4%.
I ended up doing a consultation with Buysellba. That was very helpful! They explained the process in detail over almost 2 hours. They also referred me to a great realtor, Pablo that helped us find a new construction near Palermo Soho. The building is almost finished. He was very patient with us. His English was good enough for us but he was not fluent.
I didn't need to fully retain the company as I am down here and could sign the closing myself. Like
@Johnny I used their Escribano and she was terrific! Her name was Angie and she got our CDI tax identification number for me. I also got a referral to a private money transfer firm that helped us transfer some funds down here that we needed for the initial offer. All the contacts that we got were great.
When buying here you simply can't compare the experience to the US or you will go crazy. We initially were going to buy something that was older but we used another company that Buysellba recommended for an inspection and they said that the pipes and electrical wiring in the building were very old and would eventually need to be replaced. We loved the older architectural but didn't want the hassles of having to deal with issues later.
