 President Joe Biden is working to set up a federal cap on rent prices. He'll unveil details soon in Nevada, a state that's seen one of the biggest increases in housing costs nationwide. Biden's plan would eliminate a tax benefit for landlords who increase their tenants' rents more than 5% a year. It would only impact landlords who own more than 50 units, which represents about half of all rental properties. It would not apply to units that haven't been built yet.
