Well I feel there is some kind of safety net meeting in a person's home because a title company/vendor company knows where your going, what time you are suppose to be there, etc. - if you turn up dead or missing or hurt don't you think they would know who did it.  That is why I think it is safe - most people don't hurt people that several others know exactly where they are down to the actual address.  As far as mileage, I limit mine to 25 miles, unless an instance that has happened before where it is at a bank and a commercial closing - I have been asked to do that when the loan officer was on vacation but I, like Kevin, charge a premium price for that.
