The majority of housing is in the private sector. And the loss of existing affordable housing is happening in the private market. If we continue losing less expensive rentals in the private market at a higher rate than we can build in the non profit market, this will not solve the crisis.
Creating more supply in the private market without serious affordability requirements, unfortunately, will not improve affordability.
We need regulation to stabilize affordable rental in the private market, AND more new non-profit supply.
