All very good advice here -- we did the pros & cons in a notebook for each of our moves.
We've moved three times in the last six years for job "advancement." Even though my husband's career is very good & "advanced," we still took a hit emotionally & financially with every move.
Our children are getting older (eldest is 7), and she never ever wants to move again. Moving is really like divorce or death -- it stresses you out in ways that you don't even realize. (Talk about slipping into a depression!)
Do the pros & cons & never underestimate the value of family. We constantly say we want to be at least 500 miles from our families with all of their "drama" -- but even a drama-filled family is better than having absolutely no family.
Now we refuse to move until the kids are grown & out of h.s.(in 15 years).
Most of our moves were due to economic/career moves -- and we would make the same decisions again given the same circumstances -- just that with each move -- it dawned on us that the grass is not always greener. And whatever you do -- don't buy a house until you are absolutely sure (6 months at least) -- that you want to live there for the next 20 years.
We did that twice -- buying beautiful homes (within weeks of moving to an area) & then deciding to move to a new state in just 3 years. Realtors loved us.
Right now we are leasing a nice home & taking our time to figure out the best neighborhood -- at least we found the right town for us in Florida (That info. only took 2 years to learn.)
Good luck.
p.s.
the mom who said bad memories are like ghosts -- they follow you -- is correct. bad memories are in our brain -- not in places. (Unless something awful happened in your house, then maybe a local move is all that you need -- change the house, not the town or state.)
