Peter Schiff called the 2008 housing market crash — now he warns a 'housing emergency' is coming. Are you ready?

Economist Peter Schiff made his name by predicting the 2008 housing crash. Now he's ringing the bell for another potential crisis in America's housing market — and it could see a wave of homeowners mailing back their keys.

"Why are housing prices so high?" Schiff asked in a YouTube Short last September (1). "Because for a long time, the Fed kept interest rates at zero, and so a lot of people were able to get really low mortgages, 3% mortgages, 4% mortgages."

"And because homes are bought — not based on what the home cost — but based on the monthly payment, the lower the monthly payment, the more somebody could pay for a house. Now you have a problem where housing prices went way up, but then mortgage rates went way up, and home prices never came back down to levels consistent with more expensive mortgages."

Schiff believes prices will "eventually" fall to match today's higher rates — a painful adjustment that, he warns, could trigger "a housing emergency."

"It's going to create a bunch of defaults and a lot of people are going to walk away and mail in their keys because they can't sell their houses for more than they owe," he said.

Here's a closer look at what he's saying — and how you can protect yourself against any potential market shocks.

Schiff is right about one thing: Mortgage rates have indeed surged. The average rate on a 30-year fixed mortgage has climbed from a low of 2.65% in January 2021 to a peak of 7.79% in October 2023, before falling to about 6.55% as of July 2026 (2).

Normally, higher borrowing costs can cool down the market, but prices remain stubbornly high, with the median price of a new home above $405,300 (3).

According to Schiff, these conditions could cause a cascade of defaults if house prices adjust suddenly and owners are left owing more than their homes are worth. It could even trigger another housing crash like the one in 2008, when many underwater homeowners simply mailed their keys to the lender and walked away.

But today's market is also different. Lending standards are tighter than during the subprime mortgage era, making widespread negative equity less common. Supply constraints are also a factor: Realtor.com estimates that the deficit in housing widened from an estimated 3.8 million homes in 2024 to 4.03 million in 2025 (4).

Either way, other real estate gurus are still warning potential homebuyers to stay away in this tough market. In an interview posted on his social media in March 2026, billionaire Grant Cardone said, "Homes, going forward over the next 30 years, will prove to be an even worse investment than the last 30 years (5)."

"My advice to all young people: Never buy a home until you're super wealthy."

While Cardone doesn't advocate buying a single home as an investment, he is a titan of real estate: He claims to own $4 billion in real estate assets, including several apartment and office complexes in Florida, where he is primarily based (6).
