The low stress Irish life seems attractive. Hope the family will be able to increase their income without too much stress. They rented a $6000 Saratoga house for 11 years, missed an opportunity to buy a home during the downturn. From their spending, they must have been making really good income, at least 300k a year.
High stress level is what I do not like about Bay Area. When you achieve financial independence, you can quit your job. Is the life going to be a lot better in Bay Area when you do not need to work?
Once your passive rental income is enough to sustain your life, you can quit your high stress and high income job, but instead working on a self employed job such as a realtor, or a hobby real estate investor like wuqijun. Is that going to be a better life than working your current job? You just work as much as you want, and have no pressure to work when you do not feel like.
