San Francisco has the worst housing affordability of any major US city. Even Google engineers earning $175K can only afford 18% of local homes. Teachers and nurses are effectively priced out.
At today's 6.7% mortgage rate with 20% down, the monthly PITI on San Francisco's median home is $7,744. To keep housing under 36% of gross income (the back-end DTI threshold most lenders use), you need $278,000/year — 242% of the city's median income.
The local median income of $115,000 leaves a gap of $163,000/year. This means the median household needs to earn 142% more to comfortably qualify for the median home.
These are market averages. Your situation depends on your income, debts, and credit.
