The real reason I see for you to sell is that you do not plan to be in the house for anything more than a year or two. In that time it is doubtful you will get a cent more than yesterday, but rather possible you will get less.
I know you have already accepted an offer and all, but with our economy looking like it is gonna be hurting for a while, just reasses that new job possibility. If you realize that you are not going anywhere for a very long time (since you love your house) and are gonna keep your current job, then stay. If you are still planning on bailing out in a year or two, then sell and save that difference in rent for whereever you are going.
Best of luck to you.
