I wrote a blog here on Trulia back in March about this very topic. You can read it here:
The Nampa school district has a pretty good website that you can use to double check any home to see what schools are associated with each home.
Since you are targeting a certain type of property, it is important to work with a Realtor that understands how to use today's technology to help you find it. What I mean is that a Realtor (like me) that understands how to use the MLS as a database can have it search daily specifically on your behalf for your specific homes meeting YOUR criteria and push an email to you with any new matches or listing changes (if homes you looked at sold, have offers, price reduced, etc.)
For example, there are currently 23 homes listed for sale in our MLS for Desert Springs Elementary School. Seven of those already have contingent offers so that leaves 16 readily available. Some are brand new homes that are just priced out and not built yet while others are completed new homes. There are also some great deals on some bank owned (foreclosed) homes in that school district including a great 3 bedroom 2 bath home with a 2 car garage that is a five year old single level home with 1,239 sq. ft. for only $78,500!
Hope this helps! If so, give me a "thumbs up". Feel free to call with any other questions!
