All, please help with this negotiating question.

I'm in the midst of negotiating for a new position. The offer I received came with a salary comparable for someone with no experience (and the person making the offer acknowledged this). Is it obnoxious to come back asking for $12,000 (in hopes of settling at $10,000 more). Otherwise, financially this move may not make sense for me/my family. Help!

DH is resistant to a move right now, particularly with everything going on with the economy. Being an adult is stressful!
