Well, this proves something. It's not a matter of money. It never was. I once ran the numbers what it would take to successfully upzone a 2 million dollar house so that the resulting rent would be reasonable. The goal was $3k/month for 700sqft which is well below $61k/year. The minimum upzoning needed would involve a 2 story building with 6 apartments in total. At $5k per month one could probably get away with a triplex that would even fit in with the rest of the neighborhood and by fit in I mean it would be indistinguishable from every other house.

It's not the money. It's that doing the right thing is illegal.
