The neighbors must have run into some money, they refinished their apartment and organized resident meetings to make up rules and stuff (because they are importanr people now). They are installing cameras and electric door locks with those wall mounted phones where you can look at the gang of criminal thugs outsife before buzzing them in.
They would be better investing their money into stocks or something. (I read There is a push for exchanges here, but in general Latin American business freak out about selling stock in their companies to non-family and people are paranoid about putting money into companies because it's largely unregulated. That's what I understand)
But i can image i'll be hacking the phone unit and connecting a raspberry pi so i can open the door with my phone. So i dont have to get up and buzz the houskeeper in :) but we'll see. They want everyone to pay for this nonsense.
