Facing staffing shortages and supply chain problems, Zillow says its Zillow Offers iBuyer service won’t sign any new contracts to buy homes through the end of the year.

The aim, the company said in an announcement yesterday, is to work through its backlog of already-signed homes yet to close, reducing its renovation pipeline. The company will continue to market and sell homes through Zillow Offers, however.

“We’re operating within a labor- and supply-constrained economy inside a competitive real estate market, especially in the construction, renovation and closing spaces,” company COO Jeremy Wacksman said in a statement. “We have not been exempt from these market and capacity issues and we now have an operational backlog for renovations and closings. Pausing new contracts will enable us to focus on sellers already under contract with us and our current home inventory.”

Zillow Offers is a service to homeowners to sell without having to coordinate repairs or host open houses or showings. After buying a home, Zillow prepares it for sale by doing the same type of projects a typical seller would, then lists it on the open market.

Real estate industry analyst Mike DelPrete wrote in a note to subscribers that Zillow also appears to be a victim of cooling market conditions in iBuyer hot spots like Phoenix, Arizona over the summer.

“The current problem seems to be unique to Zillow. The other iBuyers saw the signs and made strategic adjustments months in advance. Zillow either missed the signs, or decided to proceed despite them,” he wrote.
