These are professionals with additional training and a stricter code of ethics.

Being in the right area, especially near a popular train/subway station, makes a huge difference in the value of a property.

Would you share 3 specific things I should do during my "training period" (if it includes a book, which one)?

Property Managers:While realtors are great at buying and selling homes, most aren’t trained in the intricacies of tenant screening.

During this time, I found myself unemployed and having difficulty finding a new job due to not completing my degree or having formal training beyond high school or military.

However, I have found trails of information on the internet and FHA-type websites indicating if you relocate due to work, that you are not bound by the 1-year rule once you begin at your new place of employment.

I think investing from Internet is pretty tough right now. 

I do not wish to waste my time watching videos,searching the internet for how tos and what I should be doing.

Highly suggest some YT videos for training / help on the platform.

So, many landlords legally "bribe" these S8 tenants to move into these Neighborhoods/Properties with free appliances, TVs and internet.
