Sellers in some US metros are growing so frustrated with the state of the housing market they are de-listing their homes at an alarming rate.

Beyond slowing sales and flat prices, de-listings have become a defining feature of this summer's housing market.

Nationally, de-listings rose 57 percent in July compared to the same time last year, reports Realtor.com.

This continues a sharp upward trend.

On a year-to-date basis, de-listings are up 41 percent.

The ratio of de-listings to new listings — a metric that captures the flow of homes in and out of the for-sale market — climbed to 0.24 in July.

This means that for every 100 new listings that came onto the market, 24 previously listed homes were removed without selling. By comparison, the ratio was just 0.17 a year ago.

Miami is ground zero for this concerning trend. The Florida city saw 57 de-listings per 100 new listings in July.

Following Miami, Phoenix AZ, saw 45 de-listings per 100 new listings.

Then Riverside, CA, which had 34 de-listings per every 100 new listings, then Tucson, AZ, with 33 de-listings per every 100 new listings.

The staggering delisting rate suggests that sellers are increasingly unwilling to accept current market prices or conditions, and are choosing to pull their homes from the market instead.

This pullback could put downward pressure on inventory later in the year, reducing buyer choice even as market momentum slows.

Another contributor is that homes are currently taking longer to sell.

The typical home spent 60 days on the market in August, seven days longer than last year and now above pre-pandemic norms for the second consecutive month.

This was the 17th straight month of year-over-year increases in time on market.

'The takeaway for buyers and sellers alike is that local conditions, not national headlines, are what matter most for pricing, competition, and timing,' said Danielle Hale, chief economist at Realtor.com.

It is not just de-listings that are alarming Americans. 

The housing market across most of the US experienced what experts are dubbing a 'cruel summer.'

Homebuilders felt the pinch too, slowing construction as the market stalled.

'It's the Anna Karenina housing market: Everyone is unhappy, but each in their own way,' said Realtor.com senior economist Jake Krimmel.

Buyers, sellers, and builders each face unique challenges, yet the result is widespread dissatisfaction across the market.

As a result, the market was 'grinding through a cruel summer,' Kimmel said.

'Buyers face steep affordability barriers. Sellers are losing market power but are futilely resisting. 

'And builders are now pulling back even as the nation remains short of four million homes. And regional markets are dysfunctional in their own unique ways.'
