Hi J.!
How exciting!
There are several wonderful school districts. My absolute favorite (because I went there) ;o) would be Alamo Heights. AH is an excellent College Prep school. Second, would be the Schertz/Cibolo, Clemens High School, area. Not far from Clemens is the new Steele High School area. If your Husband is willing to commute, if he will be working in San Antonio, is New Braunfels. There are two high schools in NB; New Braunfels and New Braunfels, Canyon. Both are excellent schools. In my opinion, the best elementary school would be Hoffman Lane Elem.
You'll also find great housing in the Stone Oak area but the traffic in that area is Horrible! I find it a lovely place but very stressful.

Not sure what price range in housing you are looking for but Olmos Park in AH is awesome. They are older and some historical homes. There are a few new home communities in Lincoln Heights off of Broadway, in AH.
In Schertz, you can find many new home communities off of FM3009/Roy Richard Drive.
In the Steele area, you can find many new home communities off of FM1103 right off of IH35N.
New Braunfels has beautiful communities spread out all over. River Chase is gorgeous. You should take a drive through Gruene off of FM306; exit 191 North. You might also want to take a drive up FM306 and drive down Hoffman Lane and past Hoffman Lane, where you'll find River Oak and River Chase. There are two new home communities off of exit 193 that are very close to the highway for easy commute.
