re: Here's a budget breakdown of a couple that makes $200,000 a year and yet is scraping by

That house is more like 700 sq. Ft. Or it's a crack house. To buy anything ok to inhabit in SF over 800sq. Ft now will prob cost near 1mill. Plus don't even think about getting a house. We are talking near efficiency level condos. Traveling south price hangs around 1 mil until San Jose. That is about an hour and a half commute by train. Each way. 3 hours a day lost right there. So now how do you find time to cook if you are working 10 hours plus a day with 3 hours commute. So 1k for food budget seems good.
Average rent for one bedroom in SF is about 3500. Oakland is rising and I think it is north of 2k now for one bedroom..

Plus food is Def more expensive in SF. Sandwiches for lunch in the city are more than 10 dollars. Not exactly full of fast food options either.

If you are driving into City, parking will get ya. I think a space runs about 300 a month or 15 to 30 dollars a day.
