From a guy who rented in Vista for 3 years: If it’s not Shadowridge *West of Melrose* avoid it like the plague. Of course North Vista has some exclusive homes, but they are in the 1 million range. You have to drive through the crappiest parts of Vista to get to the house you indicated.
West of Melrose and Shadowridge in Vista kids go to Lake elementary and Madison, which are pretty good. All other schools pretty much suck in Vista.
San Elijo is getting hit a little hard probably because of all the new developments, and also the lots tend to be a little smaller than Vista. Also more flippers bought into the new developments there. Rancho carillo elementary and San Elijo middle are quite good – much better than the Vista schools.
