Honestly, I would pick the home you love where the neighbors look nice. You have 4-5 years to worry about school. Schools can change a lot by then (even the best ones) and your situation may be entirely different. Kids will make it wherever with the right parental support. You will be a great mom, so live where you are happy and the rest will be okay. Of course, that doesn't mean move to inner city D.C. and really stack the odds in the wrong column.
If the school is a problem in 5 years, you can worry about it then. Elementary is mostly the same. The real differences at that level are between the teachers and not the entire schools. The major differences between schools are more apparent at middle school and high school. So, pick your house. If the elementary teachers your kids get are a problem, you can ask to have a different one. At that rate, you got 8-10 years to worry about moving to a good school.
Just MHO.
