US President Donald Trump says he will ban large institutional investors from buying single-family homes, according to a Wednesday post to Truth Social. “I am immediately taking steps to ban large institutional investors from buying more single-family homes, and I will be calling on Congress to codify it,” the president said in his post. “People live in homes, not corporations.”

It is unclear if Trump has already received congressional approval to move forward with such an act or if it is an unfulfilled promise. This decision would require a bipartisan vote of approval first. Additionally, the president said he planned to roll out more housing and affordability plans in the coming weeks.

Wall Street institutions, including Blackstone, have bought up thousands of single-family homes since the financial crisis of 2008 led to a wave of home foreclosures. The trend has attracted criticism from housing advocacy groups and lawmakers, including Democrats, who claim institutional landlords have stoked rent inflation. As a result, Trump is looking to end that mass-purchasing pattern to free up more opportunities for families to purchase these homes.

Trump’s plan to ban large investors from buying single-family homes is likely a move to ease concerns over his cost-of-living plan, which is a term he has said “doesn’t exist.” The US President is due to sign more executive orders this week. However, its unspecified if this decision will be a part of those upcoming orders. Real estate giant Blackstone (BX) saw its stock fall 9% after Trump’s announcement.
