How early is to early to invest?

[Carson Scott]

I'm 17 currently and my goal is to invest into a rental property by the time I am 21. Does anyone think I can make that I have $3,000 saved right now and i'm very good at not spending any money and living frugally. Does anyone think I can invest at an early age? any good ways to speed the process up? Can I even get a get a loan from the bank or a private investor that young?

Stop using words like, "speed the process up".  That will lead to you making bad decisions based on time if/when you start getting close to some arbitrary timeline and you haven't reached your goal yet.
