 The plan proposed by President Biden would include a measure aimed at corporate landlords that would take away their federal tax breaks if they don't cap rent increases at 5% for existing units. That would apply to landlords who have 50 or more units, which, according to the White House, would account for about 20 million rental units nationwide. The plan also includes repurposing public land to build affordable housing. That's Fox's Tanya J. Powers. The proposals would need congressional approval.
