What other industry dealing with hundreds of thousands of dollars of people's money lets people become licensed in three weeks and no formal education? 

A lot of people seem to think it can be a side hustle.

There should be an amortization schedule created prior to contract signing so people understand what the payments should be on a monthly basis with no confusion.

Learn from people with 30+ years of experience, not the YouTube gurus that bought all their investments in an ideal market.1.

So many people get suckered into these "deals". 

People get busy and forget.

If I was your brother getting my REI portfolio started, is there any advice, strategies, links, literature, articles, or people to follow that you would recommend for someone extremely leery of financial risk?

I would also love any advice people have from working with creative financing in similar situations. 

Just was curious of other people’s experiences.

Looking forward to meet like-minded people.
