How on earth did you pull that off?
Assuming you're not buying high end vacuums and bespoke suits, the rent alone would be almost half that $100K, and that's for a ONE bedroom apartment!

lol. San Francisco. You know as well as I do how large the Bay Area is.
wtf would I live in SF? (it's probably the shittiest big city in the US, imo).
My rent for 1 BR was between 1100-1200 living in Berkeley and Albany in that time. And yes--I know that while Oakland through El Cerrito were some of the last holdouts in the entire Bay Area, the rents there have now caught up and skyrocketed during the time I was still paying ~2010 rent in 2015.
When I left my last place, my 1180 rent was re-offered for $1500. According to that landlord, the first applicant was (no surprise) a silicon valley jerk that scoffed at the price and requested to pay $1800....wtf.
The temporary place I was living the few months before moving out here was $1200 (sorta took over that lease) and walking distance to campus--way undervalued even for when that lease was signed several years earlier. Landlord supposedly rented that out for $1400 after I left (it was the advertised CL rent). That landlord was also super sketchy and turned out to be real scummy. Tried to scam my GF out of her security deposit by making some bullshit up after I was gone (We did a walkaround on move out and everything was great--I even had a witness), so that oddball rent makes sense.
Anyway, SF is the absolute last place I would live in the Bay Area.
But rent, although large, is one piece of the puzzle. Where one chooses to live and how much to spend on that living really depends on where they work. How much does it cost to get to work and back every day? That's a huge cost that most ignore. If it works out that I happened to work in SF with x salary and rent + getting to work is cheaper than living across the Bay or southbay, then I would do it. BART is pretty poor with monthly, work-based passes though. I recall the minimum expense for monthly BART commuting to be about $120 (and this is only taking it a few stops). I happened to either be able to walk to work and back every day (can't beat that), or take AC Transit bus for $30/month.
