> Why are prices for an apartment in SF only 3k/mo instead of 30k? Surely under your reasoning a landlord could just wait and get a tenant at any price they set?

No, because local wages cannot sustain those prices

If local wages could sustain those prices, then yes all rents would rise to that new higher local income level

That is (quite self-evidently) prices are so phenomenally high in ultra high-income areas like SF

Every single landlord is setting prices by the same metric: what can the people who would live here be able to afford? Competition between landlords is almost nil, which is why you find almost no "deals" anywhere. The market is totally efficient. Everyone agrees on how to set prices: by local wages.

> Competition between landlords is almost nil

In fact, collusion with the likes of yeildstar is the name of the game. Everyone is setting prices based on what the algorithm tells them to set prices and they all benefit from that uprise in prices because there's basically no competition decreasing the price.

There's also been a steady consolidation of ownership of rental units which also artificially increases prices.

There's a reason nowhere in the country at this point has affordable housing.
