This is a topic that has various points of views but from one that works in the business I can say categorically that being a good realtor or real estate agent is a difficult job in Buenos Aires with very long hours, high expenses, and a predatory market that makes our job doubly hard.
A good realtor will take exclusive listings, priced correctly to the market, qualify and market the property to find the right buyer who matches the apartment. It is not easy to sell a listing to the suprise of many and most realtors are lucky if they sell one property a month. If you are an independent agent on commission basis your charges will exceed US 1000 per month most months and you can have dry spells where you are working 80 hour weeks with no incomes coming in for prolonged periods.
The most important key to success in this field is dedication and belief combined with knowledge of the market . Many excellent properties are not sold because the agency did not dedicate themselves to the product to the detriment of the seller.
I can think of three properties that I sold within 6 weeks that were listed with other well known companies for more than 12 months.
When I investigated the non sale there were many reasons but the most obvious one were very few showings, and a disinterested sellers agent who had no love nor knowledge of the listed property . For me I will not take a property listing if I cannot give my full commitment to the sale . This is paramount to being successful.
In regards to buying directly I have rarely seen a non agency listing that was better priced and in many cases they had legal issues with declaration of metres and selling price making them a unattractive investment. There is a lot that goes into buying and selling a property that many do not understand . The legalities of transactions and requirements set by laws are paramount to create a successful sale.
When one takes a listing with good intent and invests his time and his monies for a prolonged period it is a travesty that some will try to take the contact from you making a appointment to view the property and then with all the information at hand go directly to the apartment trying to bypass the listing agent.
When buying property make sure that you study the market first and do not buy a property impulsively but from the head . Location is most important combined with quality of construction and price. Make a calculated risk with your purchase as this will be a long term investment for 7 years minimum . In my opinion the better areas for investment in Buenos Aires are Congreso, Almagro, Balvanera, San Cristobal and Colegiales. Recoleta , Barrio Norte, Palermo , and Belgrano are good investments as well but make sure that you are paying the right price for the listing as there is a huge difference in prices for quality .
There are many gems out there for US $ 1000 a metre in great neighbourhoods that require little work . Good luck with your search.
