earlyretirement, I am gathering from your posts that you are not currently living in SD County.
Can I just ask, if you will be working primarily from your home, why only TWO zip codes on your list? There are MANY zip codes in SD County that have fairly new construction homes with 3500 – 5000 sq feet ranging in price from $600K to $1M. Many of these properties have quite LARGE lots that DON’T suffer from arterial street or highway noise.
Some of these zip codes have homes with NO Mello Roos and NO HOA or LOW Mello Roos and SEVERAL arteries in and out of their respective areas.
Of course, there is nothing wrong with your choices – to each his own – but I’m curious as to how a potential buyer from out-of-county/out-of-state with whom location is really no object becomes fixated on TWO zip codes instead of branching their search out just a bit.
