Yes it is all related but not on a 1 to 1 basis or as simply as Cow or PD tries to make it sound. Trying to compare El Cajon and La Jolla really shows how clueless Cow is. They just dont understand how RE works. For current SD residents they tend to be more likely to evaluate one community against the next but relocation buyers tend to think very differently. Here are a couple examples.
A past buyer of mine not satisfied where they were living decided to move. The father’s career allows him to live anywhere within 30 minutes of an airport. The family pulled out a map of the US and identified 3 places they would live of which North San Diego County was one of them. After spending a couple days here the choice was Encinitas/South Carlsbad. They also visited the other places on their list on the west coast. Ultimately they were comparing Encinitas with communities near Portland and Seattle.
A current client of mine works from home and can live anywhere. His wife works in the jewelry business and can work anywhere she wants. They are evaluating portions of Orange County (closer to family) with Encinitas/Carlsbad (more affordable, nicer and close to GIA).
Past client relocated here from East Coast and moved his business here. Because of climate, type of community they were looking for and schools they only considered Encinitas area or Carmel Valley.
Relocation buyer considering two job opportuniteis with same multi-national corporation. Was looking at Carlsbad/Encinitas vs. Beach areas south of El Segundo in LA (Manahattan beach, Redondo, Hermosa etc.). Liked SD area better but ultimately chose LA because of job opportunity.
None of these buyers were evaluating communities relative to other parts of SD. They were comparing them to other parts of the country, which are more expensive or which they ultimately found less desirable.
