Actually traffic aside, LA is a more agreeable city than it has been for a long time, with neighborhoods being spruced up everywhere. Housing prices reflect this.
Lol!! Now it's high RE prices indicating that LA is more agreeable than it has been for a long time! That has to qualify for the Dr Pangloss Award, with a Pollyana Cluster.
The lowest interest rates in 30 years, the avoidance of the stock market, and LA being the POE for the highest immigration in a century is what is driving the RE bubble here. It's certainly not that SoCal is more desireable.
