Look at the State tax schemes in every state you might move to.

As a really good realtor for their suggestions. Likewise a good tax/inheritance attorney -- and also a expert stockbroker to put together a suggested varied, balanced and robust yet safe stock portfolio for you for what does not get spent on a new home.

And for that move, you need to decide whether to buy the new home for cash, or with a down payment and whether or not it would be worth it to rent out or simply sell off the residences; if you rent, a bad renter can drag out the eviction (and make you go to court) for 6 months; and trash the property during that time; to avoid the "broken toilet at midnight" calls, you will need to hire a management company for that stuff; for which you need to pay (typically) about 10-20% a month of the rental, often times.

I hope you choose well. Go with your wife and actually visit where you might move and talk to some locals. Perhaps a connection can be found in your church denomination near or in, your new possible hometown?
