How do you reduce investment risk outside of your area?

[Hideyuki Gojima]

I am interested in investing in areas outside of my area. My area means, I have some brokers that I personally know are there.

BP or Roofstock show some investments that interest me but how can I know know if what it says is actually true?

Of course I will do all the due diligence as much as I can by myself but I will appreciate if anyone in BP community can share some tips. 

Some good stories and bad stories? What to avoid?

Thank you,
