This is a tough question because relocating means moving to a completely new area. It might be ok to answer with a no, but I would answer with a maybe. Here is an example.
I guess it would depend on the location and the pay. If everything is the same, I would rather stay here because this is where I grew up. But I would be willing to consider it.
This answer is not saying yes or no. This is saying maybe in a polite way. Don't answer with a direct maybe. That is bad. Instead use something similar to my example. If you are willing to relocate, it is an easy answer.
I love change and I'd definitely be willing to relocate.
