Yes. Through the national housing strategy, create more non-profits and housing co-ops and more non-market housing, as well as an acquisition fund. An acquisition fund for non-market actors will take housing that is existing and affordable and keep it affordable in perpetuity, as opposed to having it fall into the hands of financialized actors, which have been shown to compromise the affordability.
Once that affordability is lost, we can't ever get it back, so now is the moment to act.
