Making offers?

[Junior Salters]

Is it not just plain dumb to make an offer on a house that you haven't seen the inside of completely? Or is it common? I see alot of these "we by houses nationally" do it and I assume they can't see majority of these houses? I'm asking because I got a call back from a absentee owner who seems decently motivated. I know this may not be a capture, but for future reference should I make sure to see the house before with a contractor or just learn to estimate repair?
