Portal Lead Costs
What a Portal Referral Fee Takes From One Closing
Updated
Bottom line: Zillow's Flex success fee runs 35 to 40 percent of the commission, per Mike DelPrete in February 2026, and Zillow says it is owed only after a Zillow lead closes.
What share of one commission does a Flex success fee take?
In February 2026, Mike DelPrete reported that Zillow's Flex success fee rose from 35 percent to 40 percent of the commission in six markets. Mike DelPrete notes the fee had held at 35 percent for years before that change.
Mike DelPrete writes that the fee follows a graduated band, and in all but two markets Zillow's average home value sits in its highest band, 40 percent.
Across programs, Real Estate News reported in February 2026 on a Consumer Policy Center report putting commission-based referral fees at 30 to 40 percent at closing. Read your own Flex terms for the band that applies to your market.
When is a portal's share owed, and what is paid before then?
Zillow's shareholder letter for the third quarter of 2019 describes Flex this way: the agent pays the success fee only after the deal with that lead closes.
HousingWire reported in October 2025 that Flex leads reach teams and agents with no upfront cost.
Real Estate News carried Zillow's reply to the report, which says agents in its Preferred program pay nothing unless they have helped a client buy or sell.
The cost lands on the closing itself, as a share of that one commission.
How do you set one closing's cost from each lead source side by side?
Start with the gross commission on a single closing, then take off each source's share as a percentage. For a Flex lead in a market at the top of the band, that share is 40 percent, using Mike DelPrete's figures.
For a team lead, ask for the team's split in writing and set it on the same line. Then list what each share pays for, side by side.
On our team, the leads come from the team's own AI, SEO and marketing work, at 525+ a month as of October 2026. ISAs qualify those leads, set the appointments and introduce you to the client. On the plan for experienced agents, ISA appointments open after your first 30 days.
The support team also handles transaction coordination and compliance: timelines, inspections and appraisals, title and lender contact, and closing documents. Weigh each source's list against its percentage.

Questions & answers
What do Houston agents ask about this?
Do portal referral fees keep commission rates high?
The two sides disagree. Real Estate News reported in February 2026 that Consumer Policy Center researchers say 30 to 40 percent referral fees keep rates high, because agents have less reason to negotiate. Zillow answered, per Real Estate News, that its internal analysis showed no statistically significant gap in 2025 commission rates between its Preferred agents and other agents.
Zillow also told Real Estate News that 85 percent of buyers and sellers it surveyed called their agent's commission fair or even too low. The researchers' argument and the company's survey answer different questions. For one closing, the figure you can work with is the percentage the source takes.
Do Zillow Flex leads come with a loan preapproval requirement?
HousingWire reported in October 2025 that an agent in Texas told The Capitol Forum roughly 10 percent of Flex leads must receive a loan preapproval. HousingWire presents that figure as one agent's account of the program. Ask for Zillow's written Flex terms before you count on any lender requirement, in either direction.
HousingWire's report rests on agents' accounts of Flex requirements, so read it as reporting from the field. Set any lender terms down beside the success fee when you compare sources.
When did Zillow start testing Flex, and in which markets?
Zillow's shareholder letter for the third quarter of 2019 says four markets in Connecticut and Colorado converted to Flex earlier that year. Phoenix and Atlanta made the move in the fourth quarter. Zillow estimated those Flex tests at roughly 5 percent of total Premier Agent MRR as it left 2019.
In that same letter, Zillow set out the core term: the success fee comes due after closing. For the band and terms in your own market, ask Zillow for its current Flex agreement in writing.
