The White House is outlining its plans to make housing more affordable for renters and to restore 2 million homes as housing prices climb higher.

Millions of Americans are getting priced out of homeownership or are stuck paying rent because they do not have enough money saved up to put a down payment on a home. The S&P CoreLogic Case-Shiller reported this week that housing prices rose 19.1% year-to-year in June as highly-priced homes at low-interest rates are being purchased by affluent buyers.

The jump threatens Biden’s ambitions to center the U.S. economy around the middle class as part of his major campaign promises. Two key victories Biden had in his 2020 campaign were in Arizona and Georgia, two states with increasing populations through new homes being constructed.

The White House Council of Economic Advisors posted its analysis of the nation’s housing affordability problem, highlighting issues such as housing supply not being able to keep pace with population growth, zoning restrictions and a supply shortage for renters. The White House reports that 1 in 4 renters spend half of their income on rent and 47% of renters spend more than the recommended 30%. Public housing has also experienced a supply shortage as nearly 2 million people live in public housing including children, the elderly, and the disabled.

Researchers at the mortgage buyer Freddie Mac estimate the U.S. is 3.8 million homes short of meeting the necessary demand. To increase home construction, the Biden team is proposing two major policy changes.

First, the administration intends to build 100,000 homes in three years and will increase mortgage availability through Freddie Mac and Fannie Mae for manufactured houses and buildings with two to four units. The government also plans to make it easier for would-be homeowners and nonprofits to buy homes that failed to sell in foreclosure auctions.

The government will also increase financing opinions for apartments via tax credits, loans, and grants.

Secondly, the Biden administration plans to renovate 2 million homes. This includes using federal subsidies, the low-income housing tax credit, a new tax credit for construction in economically disadvantaged neighborhoods, and incentives to remove exclusionary zoning and land use policies by local and state governments that limit new construction.

The White House warns the supply shortage could linger.
