Will you be willing to relocate if a higher salary is offered?

If the higher salary comes along with a challenging job, then surely yes.

yes I will accept

NO I AM NOT WILLING TO RELOCATE

yes of course

No.
I admit that higher salary attraction is the most attractive tools but I will consider other things too.

I will relocate if I'm sure that I'll go forward in this job and I'm not going into a dark tunnel.

No , if I m fine good company

Should estimate either experiencing in following job will be developed more adjusting own self for smooth function or giving priority to aquire higher salary not to consider merit or demerits.
Adopting in suitable job for next higher job grade is more expected rather then maximising salary

A more sincere sounding answer that still doesn’t commit you might sound more like, “I am very interested in advancing my career, and if relocating is a part of that, I would certainly consider it.”

Many workers feel satisfied and motivated in their current position , so they don't think about relocation if a good salary is offered to them because they are believer and calm minded.Others are be willing to relocate if they have financial problems , ambitious or need to have many experience in different company with different culture.So it is necessary to be sure that this post is better and has advantages.

For better career opportunities, it will be yes
