In San Diego, and perhaps San Fran at the height of the boom, a person could not and I believe still cannot drive an hour in any direction (aside from TJ) and be able to buy a SFH for under $300k. Am I wrong in this thinking?
You are wrong about the part that says “still cannot…” Below is a map of SFHs listed for less than 300K in the areas you mention.
300-350K can now be found in Clairemont and parts of Mira Mesa. Within the next 9 months I would expect to see plenty of 250-350K houses in Central San Diego.
