A few thoughts . . .
If you are making it financially, happy as a family and content in your community, what could more money do for you? Probably nothing. It might cause problems. As the saying goes "Money can't buy happiness." If you aren't content, happy, etc where you are, more money will not change a thing.
If you see your new community as not having a "family feel", you likely won't look for it anyway and will miss opportunities.
We've moved a lot and I've found that unless your school is profoundly lacking, your involvement as a parent in your school will MAKE the school a good fit for your family. Otherwise, there may also be other options such as private school and charter school.
Consider which job has better job security.
Is it REALLY better pay? We had a move once where my husband's pay increase was quickly eaten up by a higher cost of living, higher home prices, higher insurance and we had to drive further for everything and spent much more on gas.
What about extended family? Do you have the opportunity to be near extended family in either place? Is that important to you?
Do you have a church family/friends that are important to you where you are? People that are like-minded in belief are harder to find. As an example, we won't move to a community that doesn't have a Lutheran Church, because that's where our religious beliefs line up and if we don't have a good church family the rest of our life will be sorely affected.
Also think about the schools your kids WILL go to. If your kids are still in grade school, consider middle school and high school. They will be there before you know it.
Whatever you and your family decide, talk frankly with everyone in the family about the decision. Specifically that whatever you decide there's no looking back or "what-ifs". Those thoughts will quickly turn to regret and will pit family members against each other. You and your husband especially MUST completely agree on the decision.
We make 4 lists when faced with a move:
Reasons to stay
Reasons not to stay
Reasons to go
Reasons not to go
At first glance it seems like redundancy, but give it a try and you'll come up with some pros and cons that you never thought of, or how those pros and cons really will affect your life.
Good luck!
