How different are the expenses there compared to Ohio for the cost of living/etc? Would you two be more financially secure if he took the job down there or if you stayed?
What's the housing market like there? (I believe it's a buyer's market now (my sister's looking around here for a home). What are your plans if you're able to buy a home there but it takes a while to sell yours here? Maybe you could talk with a realator/research online and just check things out?
Will you need to work if you two move to Az? Will you be able to find a job in the field you like working in?
I would take a little while to sit down with Jerry and talk over some of the important questions ya'll need to address about moving out of state/etc.
And most importantly- are you going to be happy if you move? Are you going to be ok moving away from your family and just visiting? I know for me- part of the reason i refuse to move anywhere out of state from where i live now is i am SOOOOOOOO darn close to my family- for me i'd be miserable without them. I see them just about every day. So for me personally- i would have attachment issues about leaving. BUT for many people- moving is just the thing they need to jumpstart their new lives/careers!
It can be a very positive thing for people- exploring a new city, having a fresh start,etc- there are definitely pros and cons....i would just make sure you both agree on the move and research!
Good luck whatever you decide!
