When I lived in the bay area in 2000, it was 250k for a single wide on a lot maybe 10 feet bigger than the trailer. 1200 square foot 3 bedroom ranches on postage stamp lots were 500-600k... efficiency apartments were $1200 a month, and that was 20+ years ago. I wouldn’t even consider a job in Cali or NY if it didn’t come with a 500k a year salary.... cost of living there is a joke.
The people I know out there are all probably $400k/year and north. Cost of living is insane. SF proper for a couple, one right across the bay, one in Redwood City, another in Palo Alto or nearby.
When my daughter was living in SF in 2009 she was paying $1150 a month for a 400-450 sq ft apt (tiny kitchen next to front door, bathroom and bedroom. It was about 4 steps from the kitchen to the bedroom with the bathroom in between) in a house converted to 4 apts.
When she moved here to KY in 2010 she said “I am earning 1/3 of what I was in CA and have more disposable income”.
