President Joe Biden has proposed a two-year 5% rent cap on corporate landlords owning more than 50 units, affecting approximately 20 million rental units across the U.S. This plan, which aims to ease housing costs for Americans, would remove federal tax breaks for landlords exceeding the cap. The proposal includes exceptions for new construction and substantial renovations to encourage housing supply growth. While the administration is also repurposing federal land for affordable housing, the plan faces significant challenges in a divided Congress. Analysts suggest this measure may be more political posturing rather than a feasible policy, given historical difficulties in passing rent control legislation. The proposal highlights Biden's efforts to contrast his administration's housing policies with those of the previous administration.
