Is it too risky to invest in rental units far from your city of resident?

[Soroush Mir Seraji]

Hello

I am from Vancouver BC but the market here is extremely over priced and chances of finding rental properties with decent cash flow are not that high.

Recently I have been thinking of exploring other cities far from here.  Possibly fourplex or something and then hiring a property manager to take care of my rental units. 

Is that too risky?  Does anyone have experience doing this?
