Every older neighborhood in the country has people living there since the 50’s 60’s etc. Clairemont is no different! In fact if you drill into the zip code demographics. The median age is exactly the same! 39 years old. So I am going to have to call bullshit on this argument.
My point is that if that zip code has a lot of old people move in after they retired then the data is skewed with a lower median income with respect to home price. But there is no reason to suspect that given the median age.
