Making sure that families remain housed during the pandemic and related economic downtown is critical. But longer-term effects could reduce the supply of rental units affordable to people earning low incomes and prevent additional affordable units from coming online. Our patchwork system for preserving and expanding the affordable rental housing supply is inefficient. Improving it will take more capital and accelerated production facilitated by reforming policies and practices. We offer recommendations to improve the effective use of capital, to expand capacity (including supporting mission-driven owners), and to streamline and coordinate activity across government agencies and stakeholders. We also suggest ways to build trust among market actors to improve how the entire system functions.
