Good afternoon Suzanna,
Welcome to San Antonio! You are going to love it. Are you moving because of a military relocation? San Antonio is comprised of a ton of military relocations.
As for Hollywood park, it is very centrally located and is a very high desired area. Hollywood Park is very well protected and they do a great job to make sure it retains it's HIGH desirability. Currently, prices range from $229k to $975k. For your high schooler, if you live in Hollywood Park, Churchill would be the highschool that he/she would be attending. Hope that all helps. Let us know if you need more!
Best of luck on the move!
