that's only true in the US though. most other countries have better renter protection. my point was that it's not just renting that forces you to move. you moved yourself because of a job. if you had owned a house you would have had to sell it at that point.
Well for one, I am in the US. Secondly if you owned a house you can rent it out - you don’t have to sell it. It’s a better deal especially in the Bay Area since property taxes are capped.
Thirdly, I move to find better deals on rent - many places I’ve lived don’t have rent control so moving is really the only option to keep costs as low as possible. I moved states because of a job, but within the Bay Area it’s the only way to keep up a desirable savings rate.
Also, try commuting from SF to SJ every day. It’s an incredible waste of time, particularly if you don’t live near the Caltrain (and now BART) corridor.
