La Jolla Farms might be out of the OP’s price range, but I don’t know for sure. They should also look at stuff around La Jolla Scenic Drive. That’s where my former UCSD boss (prof) lives.
Re:56 corridor – there is a price difference between Carmel valley/DelMar and PQ/4S/SabreSprings/Carmel Mtn Ranch. The latter is very attractive for worker bees that don’t have super high salaries and that have to commute to Sorrento area (or La Jolla like us). For those, yea, it’s a prime destination. But those are but a (smallish) segment of the RE buyers out there, and it’s driven a lot by the commute to one or two workplaces and somewhat by schools. If you work downtown 56 corridor is not a prime location. The buyers in the eastern part of 56 corridor area buying SFRs have probably incomes between 150 and 200K on average (not the current homeowners, who may have bought long time ago).
