Private Investors- too good to be true or the best path to take?

[Taylor Hughs]

Hey BP community, my name is Taylor, I'm 18 years old and I am a highschooler in Frisco Texas. I am attending college next year at either Baylor, SMU, or Texas A&M. I have been interested in real estate for the past month or a little less and have read 3 books, listened to about a hundred hours of podcasts and videos to learn as much as I can. I just got my first credit card to start building credit for my first loans in college. 

I have recently discovered the scalable strategy of private lending. From what I've researched it almost seems too good to be true. I can't tell if people are trying to sell me on this strategy or if it really is that good. I have figured out that at my age it might be tough to get a private lender, especially without a track record but, after my first couple of deals, it seems like its just perfect to scale at an extremely fast rate. Can someone please give me an insight into this form of scaling and purchasing. 

Pros, cons, how it works, can I scale incredibly fast with it, what can i do to make it easier to obtain lends from private lenders, what loans are good paired with them. And also how it can be used in multifamily properties (ie. what loan should be the other half assuming they only cover the down payment and rehab)

Thank you so much in advance!

Taylor
