How often to visit out of state investments when purchasing

[Kenny Shiozaki]

So for the average person I always hear you should go visit the place which is obvious however the dilemma that I'm coming to is should you go to the area to get a general sense and then return home then schedule a few viewings then come back again or should you just bid on a house then if they accept it come only once? 

I'm curious to know as how many times or where in the process do most people go view the property, if at all.

Thanks!
