That on the road part will also work it's way into using my personal unit in the duplex as an Air BnB for extra cash flow as well (250 plus days a year of travel...)

Travel?

Some people offer to do this because they travel often, though you can automate monthly payments through Cozy or ClearNow which I use.

That's prime real estate from a travelers's POV.

Since I am interested about worldwide RE, it is impossible for me to travel to particular location tens of thousands of kilometers away.2.

I have a decent credit score (>750) but my brother has a much lower score (low 600's) due to some medical debt he incurred many years ago.

I joined the school of hard knocks education in rentals and built a great team as I traveled for work in 2009. 

I’ve also worked as a painter for the VA and travelled as a sandblaster/painter/laborer which allowed me to live in different cities for months at a time.

Is it education or medical debts?
