Congrats on the prospective career opportunity.Needless to say , the realtor may be somewhat disappointed if you end up moving out of state. BUT, she will want you to do what is best for you.Do the right thing, tell her now and share what is good news. Be respectful of everyone's time and put the search on hold.As stated by others, give her the opportunity to refer you to another REALTOR out of state. This will be of benefit to all. Let her know how much you appreciate her time by remembering her to friends, family and colleagues. Others have already said this, but truly is the best thing you can do.Best of luck!
