This is a truly impressive piece of work. I love your thought process and how you used that to drive what you research and how you present it.
There is no “but”, this work stands on its own and deserves kudos.
It is interesting to see how interest rates and inflation can account for darn near everything we see in San Diego housing prices, as your overlays clearly show. As others have pointed out there are other things that influence prices also, but most years that is in the noise while on rare occasion they truly do need to be factored in.
Again, congratulations. We’ll never get house prices down to an exact science because humans are emotional creatures, but it is fascinating to see how you can get into the ballpark by relating a few key facts.
