Hey Fernando: the risk of fire, paper thin walls, neighbours who may disappear at anytime with your stuff... there s a long list that someone could go on and on about. One point I would like to make is, why throw your money away? I know people who rented for over 25 years. Even at five hundred dollars a month, that s one hundred and fifty thousand dollars. ($150,000) What do you want to do? Make a hotel owner rich? I think there are many alternatives. Your question is too short to know anything else about you, but one thing I notice in the help wanted ads is that there seem to be a lot of ads for Superintendents and handy types for apartment buildings. A free apartment and a salary are included. Good luck.
It is outrageously expensive unless you get a real fleabag, and even then it will be expensive compared to a similarly fleabag apartment.
its a good idea, dont have to worry about maintaining house, only downside is that it will be small
