Foutain Hills is located north and east of Scottsdale. If you are looking at a big map of the area, look for Shea Blvd., then head out east to about 165th Street. It is completely different fron the Chandler, Gilbert. It is north of Meas on the Beeline Highway.
My suggestion would be to check out hospitals first, things that you might like, then look for housing near there. Traffic can be terrible, especially at rush hour time on the freeways.
Be aware that Fountain Hills doesn't have a hopsital, the closest thing is Mayo Clinic's clinic facility on Shea and 135th street. The closest hospital would be Scottsdale North at 90th street and Shea.
Hope that this helps...................
