The Tech Worker’s Guide to San Francisco Housing Decisions
About this Capsule
Deciding whether to buy or rent in the San Francisco Bay Area on a tech salary involves weighing high ownership costs against renting savings and long-term financial assumptions.

“The hidden story is this: you are not just “bad at searching.” A lot of Bay Area housing material is now sitting behind anti-bot walls built to stop mass AI scraping. Reddit pages in this research lane commonly return HTTP 403 with “You’ve been blocked by network security.” Academic repositories can be protected by Anubis, specifically to defend against aggressive AI-company scraping.
