    The Holy Grail Takes Shape at Redfin and Zillow

    While major U.S. portals Redfin and Zillow are busily competing on unique inventory, they're also starting to pay buyers to bundle a partner agent with their own mortgage.

    Why it matters: This is the Holy Grail in action (search + brokerage + mortgage), and it’s zero sum – every transaction a portal bundles is one that doesn't reach the rest of the industry.

    • It all starts at the top of the funnel, with Redfin now running a popup on its site claiming the “largest home inventory” in Chicago.

    Both portals are offering "bundle and save" programs that discount the transaction for buyers who combine a partner agent with the portal's mortgage offering.

    • Rocket pays a lender credit of 0.75 percent of the loan, up to $6,000, to buyers using a Redfin, Redfin partner, or Compass agent, rising to $12,000 if they sell with Redfin too.

    • Zillow just started offering a flat $4,000 to buyers in Colorado and Michigan who bundle a Zillow partner agent with Zillow Home Loans, which is the larger offer for any loan under about $533,000.

    Rocket launched its offer in May and Zillow followed seven weeks later.

    • Opendoor ran a similar play in 2021, lifting its Arizona mortgage attach rate from about 2 percent to 12 percent by offering a 2 percent discount that consumed its entire $5,000 target margin on the loan.

    Zillow's lead form is where both halves of that bundle get collected, and it has been rewritten over the past year — changing the agent language and the mortgage checkbox, two things at issue in Taylor v. Zillow, a class action brought by homebuyers.

    • "Contact agent" became "Contact a buyer's agent," and the tour flow now tells buyers the agent "advertises on Zillow."

    • The mortgage checkbox went from "I want pre-approval information from Zillow Home Loans" to a generic "I want financing information," and as of today, only appears on some listings in some markets.

    Zillow submitted a screenshot of its lead form as evidence in the Taylor case back in February, to show what it discloses to buyers.

    • Zillow's February court filing shows the checkbox unchecked, but on every listing where it appears today that I found, it is checked by default so the buyer has to opt out of the mortgage pitch.

    • A federal judge dismissed the class action on July 27 with leave to amend, finding claims of inadequate notice "implausible given Zillow's express, repeated disclosures."

    The bottom line: The high-level strategy has been known for a year, and the tactics emerging now reveal where each portal is placing its bets.

    • These are the industry’s Holy Grail heavyweights, hoping to grow revenue by investing billions into their visions for the end-to-end ecosystem.

    • Unique inventory decides which portal gets the buyer, and now the mortgage bundle decides what that buyer is worth.
