You've put me on the hot seat.
I say it would be things that will bring multiple results at the same time. One of the things around co-op housing is not only that you get people housed but that they also get some involvement in running the housing and learning about democratic decision-making. With co-ops, you also get people creating jobs and getting the services, and you learn business skills and how to run something. Things that will have multiple results are very effective right now.
