It is perfectly reasonable. But you still have to have sales or other good contact on the ground in big city. Because if in walking distance you have 100 customers you can maintain connection with people working there. If you will move to small town where you don't have customers and you have to rely on your contacts over the internet then you might get burned when your contacts switch jobs or whatever happens.
