I agree. Usually when you travel and spend times with a company, you learn the town and the people. You might relocate 1-3yrs later. But usually just out of the gate with a family and children who have school and friends - is difficult sell… Unless its like 375K salary 
and a key position to lead a plant, not just be an analyst.
I work in the middle of no-where. If I had to relocate today, after spending 2yrs in the middle of no-where. I would be okay with it now. People know me there, I know people, I have friends, I know the stores and the restaurants.
I know which Police officer will give me a ticket and which one wont. Usually this type of haircut is Garuanteed Ticket.
But Most Importantly! You find out if the Company is truly a fit, what if you relocate and 6mo later you simply don’t like Joe the Supervisor who doesnt understand code and nit-picks everything and constantly uses the phrase “Back in my days when FORTRAN was around we did it this way” and Joe is the CEO’s Son in Law… What If the Company doesn’t like you. What if.
