The person I responded to was arguing that new “luxury” housing raises rent prices across the board. If we pretend that nonsense is true then isn’t the solution to rising rent prices to stop building “luxury” housing?

My second point (that you misinterpreted) was that if developers were forced to only build affordable housing they would have to do so at a loss because construction costs in our region are too high to support a unit price that would be considered affordable. It’s not even close when you factor in added costs for parking minimums, height and other zoning restrictions, and elevated land costs due to the structure of our real estate taxes.
