Lost with a lot of information

[Account Closed]

I have been studying about investing in real estate and i came to realize that there is so many routes one can take about starting. 

I think that i am overloaded with so much information that i do not know clearly on what i want. 

I know so far that i want to obtain units so i can hold them for cash flow. But ive been talking to a few people that is around me in my daily life and they are telling me its a bad idea to do so especially if i do not have a lot of money on my own. 

I then realized that i could build capital by using wholeselling as a niche and then venture off with obtaining properties for my own. But the thing is that i just dont know exactly where to start. 

I have another problem because i do not know on what could be a realistic obtainable goal with investing in this business. 

Long story short i have a lot of questions and just need answers lol.
