Small Multifamily buildings

[Wilder Omeri yasci]

Hello everybody!! I am Wilder from Argentina.
I’ve been studying this asset class for more than a year now and I am ready to do my move for my first deal.
One thing that still worries me is that I keep listening from people that have been on this business for a long time (experienced investors) that it is not good (not profitable/too risky?) to buy buildings with less than X amount of doors (my goal is to buy my first building with around 10 to 15 doors).
Please let me know your thoughts.
My strategy (I live in Argentina and would buy in south Florida) is buy and hold stabilized or ligh value add buildings.
