Interesting topic and relevant to SF for a non-obvious reason. Most people don't know this, but if you earn between 70% and 90% of the SF median income, you are eligible for below market rate housing in the city. This means you can buy a apt in a brand new building for far about 1/3 of market rate. i.e. a $900k 2 bedroom in Hayes Valley would be around $300k BMR. Why do I bring this up? Because if you aren't in that narrow range, then you need to earn like 3-4x or more of the median income in SF to afford a house otherwise. This leaves an entire chunk of the market without any options for purchasing a house. I find it strange that the city feels that a solution like this that favors one small group and ignores everyone else is an acceptable solution to the problem. Programs like BMR need to be replaced in favor of permitting enough housing permits to satisfy demand so that housing is accessible to people earning the median income and above.
