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?
