One rule of thumb in Clairemont I have is that anything with a 1-car garage is in a crappy neighborhood. I have found few exceptions, though the 1-car garages near the transition to the better neighborhoods are a little better.
Another rule of thumb is – a house on a canyon lot will cost about $40-$50K more than exact same house on a non-canyon lot across the street.
The links above all represent the low end of Clairemont, though it appears the corn is finally starting to pop in the lower end of Clairemont. I would almost classify them as condos.
