I got them by running 2000-2250 homes with a cap of $500K in 92126 and then zooming in on the number closest to your neighborhood until detail popped up (this varies by window size). It mostly includes houses between the major roads to the north, west and east of you.
Interest rates in 2000 were 8%, and 7% in 2001. Also turns out I was wrong on 1990 as interest rates were just a little higher than 10%. By ’91, there were 9.25% and got lower from there. 2000 was actually a bad year. The peak was 1981 at 18.46% (and 2.3 points!)
