17 year old looking to get into passive income

[Paige Williams]

Greetings! My name is Paige. I am a 17 year old that is looking to get into rental properties when I graduate college. I would like to have 100K passive income by the time I am 35. I realize that in order to generate passive income it takes a lot of work and time. I am going to college next year and will graduate by the time I am 21. I will have no student debt. As of now, I have 15K saved up. This money will not be touched during college and I will continue to save. With the degree I have chosen, I should come out of college making 55-65K a year.

So my main questions are:

1) What do I need to do to meet my goals?

2) Is it realistically possible?

3) What advice can you give me?
