I'm a REI newbie, but just from a personal finance point of view $500k income + "Wouldn't mind becoming a millionaire from this as well...." is a red flag.

What are some rental property green flags you've seen that scream buy? 

Any GC that does not work like this is a huge Red Flag and you should run away.2) Also any experienced GC should have theur own state-legal contract that spells out terms clearly and protects both of you.

Qualify the contractor and highlight the benefits of working together which would include consistent work for them and regular paycheck.Personally, I'd buy the materials and never pay any money upfront, a "red flag" on its own.

.: I'm an American living and working overseas.

BAM's 14 years of experience began in 2010 - their "experience" is wholly contained within one of the craziest boom real estate markets in American history.

A whopping 98% of participants agreed.A Deloitte survey of 2,000 American consumers found that 91% of people consent to legal terms and services conditions without reading them.

Wouldn’t call it a red flag. 

Because that can be a red flag.  

I'm of the idea though that now is a great time for Americans investing internationally (because of our inflated US dollar).I know I'll be giving $10K to FIRB.
