Offerpad, Zillow and Opendoor are turning the screws on startups that offer price comparisons and claim to help consumers secure the best offer.

On the heels of our first-ever Agent Appreciation month, Inman is leaping into February with our Residential Finance theme month. Join us as we investigate how buying and selling a home is changing, from companies backing consumers in new ways to integrated services that handle the entire transaction.

Dave McLennan received the cease and desist letter from Offerpad, an iBuyer that uses technology to quickly buy and resell homes, on a rainy December day in 2018. At the time, McLennan was living in an RV in Orlando with his wife and five kids while he traveled across the country trying to build his so-called “Kayak for iBuyers,” which he had named ExitNest.

The startup is one of at least 10 new iBuyer aggregators that have popped up in the past two years to help homeowners secure the best offer from iBuyers by providing price comparisons for many of the leading iBuyers.  

Staring at the letter in disbelief, McLennan’s throat went dry and his pulse quickened. It threatened him with a lawsuit for using Offerpad’s trademark on ExitNest’s website to allegedly mislead consumers into believing that “you either engage in business with or obtain quotes from Offerpad, neither of which is true.” 

The letter dropped from his hand.

“I felt like I was going to die or have a heart attack,” McLennan said. But then he had a realization: “Wow! I’m getting close!” he thought. “We made it, we are on the radar, and we are disrupting successfully, although not as planned.” 

McLennan would later also receive similar warnings from Zillow and Opendoor. ExitNest has responded to the pushback with some cosmetic design changes, but the startup is still finagling bids out of all three iBuyers – sometimes without their knowledge, according to McLennan. 

At least two other iBuyer aggregators – Zavvie and – have also been slapped with cease and desist letters by iBuyers, and since then have made more significant adjustments to their services than ExitNest. 

The pressure underlines a behind-the-scenes grappling match that has been playing out between iBuyers and a rapidly growing number of iBuyer aggregators. Resistance from Zillow, Opendoor and Offerpad is complicating the ability of these upstarts to help homeowners shop around for the best iBuyer offer. Some of these startups were conceived as full-blown iBuyer marketplaces for consumers, but amid iBuyer hostility, have retreated to providing more discrete aggregation tools for real estate brokers. Indeed, agents are woven deeply into the business models of nearly all of these infant aggregators and may be poised to benefit from the conflict.

As an aggregator of listing data, Zillow’s opposition to iBuyer aggregators is particularly intuitive, as well as ironic.

“Just like aggregation of listings made sense to consumers, aggregation of iBuyers will make sense to consumers,” said Russ Cofano, a Seattle-based broker who once served as vice president of industry relations at “The [iBuyer] aggregators are trying to do to Zillow what Zillow did to individual brokers and agents, which is to step upstream to the consumer.”

“Nobody,” he added, “wants to be leveraged by an upstream gatekeeper.”

The brief life of Zillow’s iBuyer aggregator

The story begins in May 2017, when Zillow debuted the first well-known iBuyer aggregator. A consumer-facing marketplace called Instant Offers, it let homeowners obtain and compare bids from multiple iBuyers alongside an estimate of what a Zillow partner agent could sell the home for. Then in April 2018, the company announced it would begin bidding on homes itself through the same marketplace. 

Errol Samuelson, chief industry development officer for Zillow, told Inman in an interview at the time that Zillow believed “there’s value in having a marketplace model where the consumer can not only see an offer from Zillow but can also see an offer from our [investor] partners.”

Ambushed by the shift into iBuying, however, Offerpad quickly exited the marketplace. (Opendoor never joined it in the first place.) Then Zillow quietly shut down its iBuyer aggregator just a month later. 

“We decided that the best way to ensure home sellers received the convenience, control and certainty they deserve when working with Zillow Offers was for them (or their agent) to work directly with us and our broker partner – as opposed to third parties — to sell their home,” Zillow said about the decision in a statement.

The ‘need’ for iBuyer aggregators

But many industry observers still believe Samuelson’s original assessment was correct: that an iBuyer marketplace would benefit consumers.   

For one, consumers often aren’t aware of all their options: They include not just big-name iBuyers, such as Zillow Offers, Opendoor, Offerpad and RedfinNow, but also smaller imitators and variants, such as Sundae, Sparrow and EasyKnock. Private equity firms, such as Invitation Homes, and local investors are also in the hunt.  

But analysts say the biggest argument for iBuyer aggregators is that top-line offers, service fees and hidden costs, such as the high repair cost credits that iBuyers tend to charge, can vary widely from investor to investor. Some iBuyers also offer special perks. For example, Offerpad offers a free moving service, while Zillow always covers all closing costs, according to Stefan Peterson, co-founder of iBuyer offer aggregator Zavvie. 

In fact, compared to aggregators such as Kayak for travel services and Grubhub for food delivery, “There might be an even higher need for a [iBuyer] comparison site because the real estate transaction is trickier,” Peterson reckons. 

The iBuyer aggregators that have popped up since Zillow’s departure can be lumped into three categories.

The first applies to ExitNest. It’s a standalone aggregator for consumers — an aspiring “marketplace” — that launched in May 2018, the same month Zillow announced it had begun purchasing homes. A former home flipper and “wholesaler” who matched sellers with cash buyers, McLennan launched the site after meeting with many homeowners who were confused by, or unaware of, their options.

“They would pull out all their notes from meeting with multiple cash buyers, plus several iBuyers. They would basically ask me to … help them sort and sift,” he said. “I thought to myself: ‘This is like trying to book a flight without a travel agent 20 years ago. The consumer is begging for a search engine.”

A net sheet of iBuyer offers that ExitNest presented to a seller, and that McLennan said converted into a sale to Zillow Offers. (The net sheet estimated that repair cost credits charged by iBuyers would be $0 because the home was in pristine condition, but Zillow ultimately negotiated a $6,500 repair cost credit, McLennan said.)

ExitNest, which is only fully operational in Phoenix, hawks the come-on: “Submit once, get dozens of offers on your home with the press of a button.” But the process is not that simple.

On ExitNest, homeowners fill out a detailed questionnaire and then receive a net sheet with estimates of bids from iBuyers, not actual offers. The homeowner can then select the estimates that they like and receive real offers that can be presented in a side-by-side comparison. If the seller wants to accept one of the offers, ExitNest facilitates the transaction, sometimes through a partner agent. ExitNest looks to collect a 1 percent referral fee from iBuyers. (Offervana is another even newer standalone aggregator.) 

Zavvie is an example of a second type of iBuyer aggregator, one specifically for real estate agents. It collects real offers from iBuyers for agents to show sellers what they could net from each company, as well as what they could net by selling with an agent on the open market. Zavvie also powers a web page for brokerage sites that allows consumers to request offers.

The Zavvie team.

About 15,000 agents have access to Zavvie through their brokerages, according to Peterson; the company covers 17 markets and requested about 2,500 offers from 20 investors in November 2019. — which claims it is the second-highest search result for “iBuyer” after Opendoor’s website — exemplifies a third type of iBuyer aggregator: the matchmaker. Homeowners specify their priorities, such as speed or maximum price, and then are connected to a single iBuyer (or low-fee brokerage) that “best suits your needs.” Matchmakers, which also include HomeLight, tend to avoid pitting iBuyers against each other.

“That’s not what those companies want right now, and so that’s not what we’re going to do,” said Dolf Kahle, head of corporate development at  

Other aggregators are similarly sensitive to the preferences of iBuyers, and have tended to shift their services under pressure from them. 

Not ExitNest.  

In addition to the Offerpad cease and desist letter, ExitNest received “official notice” in a May 2019 email from Tyler Hixson, Opendoor’s head of industry relations, that Opendoor did not want to be included as an iBuyer on ExitNest, according to an email provided to Inman by McLennan. (Opendoor would not comment on the authenticity of the email.)

McLennan says this is an email that Opendoor’s Tyler Hixson sent to an Exitnest representative after the representative asked about offer requests he had submitted to Opendoor. The email says it is ‘official notice’ that Opendoor does not wish to included or considered as one of your investor Buyer options.’ Opendoor would not comment on the email’s authenticity.

Zillow, meanwhile, slapped ExitNest with a cease and desist letter in October 2019 for, among other things, “including Zillow on your list of iBuyers, and thus, misleading consumers into believing that you can obtain a Zillow Offer on their behalf.”

McLennan has stopped displaying iBuyer logos, but he hasn’t stopped obtaining offers from any iBuyers.

“We have some proprietary workarounds to navigate and counter the restrictions the iBuyers are giving us that I obviously can’t elaborate on,” he said. “The reality is once we get to settlement, they buy the house if it fits their buy box.”

Pivoting under pressure

Zavvie finessed the situation differently. It originally launched a standalone aggregator in March 2019, but by July, it had taken the site down and switched to providing an aggregation service for brokerages. This service initially included a consumer-facing website tool that would predict offers from Opendoor, Zillow and Offerpad — a practice that is particularly irksome to iBuyers.

But Zavvie ended public access to the tool in October, according to Peterson. However, it remains publicly accessible through the website of at least one brokerage, Better Homes and Gardens Real Estate Metro Brokers.

IBuyers had told Zavvie in meetings that they wished “you wouldn’t exist at all,” Peterson said. And Offerpad had sent a trademark-infringement cease and desist letter that led Zavvie to stop displaying Offerpad’s logo.

But the primary reason Zavvie — which was spun out of the Boulder, Colorado-based brokerage 8z Real Estate — scrapped its standalone site was to focus on catering to agents, he said.

He emphasized that Zavvie has working relationships with iBuyers. But Dan Noma, a broker with close ties to Opendoor who co-created the iBuyer training program iReal Estate Pro, claims Zavvie has long been Opendoor’s “biggest arch enemy.” (Opendoor, Offerpad and Zillow all said they do not partner with Zavvie.)

In late January, Inman viewed this net sheet of iBuyer offer estimates generated by Zavvie for a home on the website of Atlanta-based Better Homes and Gardens Real Estate Metro Brokers. The address that Inman entered to see the net sheet for is a home owned by Zillow. It had a Zestimate of $239,051 on Feb. 11. Zavvie says it has removed its consumer-facing estimator, but the estimator is still publicly accessible through a link on Metro Brokers’ website.  

IBuyers can also influence aggregators without threatening them. Take OfferBarn, a Zavvie-like service.  

The startup’s creators briefly aspired to build a standalone aggregator, but they quickly scrapped the idea after realizing that iBuyers would balk, according to Scott Martineau, CEO of OfferBarn and a broker-owner of Atlanta-based Red Barn Real Estate.

Instead, they built a prototype that aggregates offers on behalf of agents behind the scenes. They then tweaked this prototype after Offerpad began significantly delaying its delivery of offers, according to Martineau. Rather than send offer requests for agents through the same email address to Offerpad, they switched to sending such requests from the agents’ individual email addresses– an arrangement that Offerpad seems to prefer.

When asked about this, Offerpad said in a statement that “we may not accept requests from an agent if we determine that it may result in increased fees, unnecessary delays, or other disadvantages to the home seller.” 

A sample OfferBarn net sheet of iBuyer offers. (These offers were not real offers.), the matchmaker site, has also felt the heat. It decided to dissociate itself from Zillow after receiving a letter from the company demanding changes to’s display of Zestimates, according to Kahle.

Now it only displays an estimate of what a generic iBuyer will pay for a seller’s home, called an iValuation. And it never directs consumers to Zillow Offers.

“I would love to do business with Zillow, but I haven’t had the energy to try to bridge that alliance,” Kahle said. displays a generic iBuyer offer estimate — called an ‘iValuation’ — with a button users can click to connect with a single iBuyer. does direct users to connect with multiple iBuyers out of sensitivity to their preferences.

The hostility from iBuyers is making it difficult for aggregators to actually connect consumers with the “best” iBuyer offer — even though that is sometimes their pitch., another matchmaker service, would like to present multiple iBuyer bids to consumers in side-by-side comparisons, similar to how it presents multiple agents to consumers. But it was only able to secure partnerships with iBuyers by promising to only deliver one iBuyer bid at a time, according to president Matt Woods.

“[Real estate agents] are all like, ‘Sweet let’s do this. We feel like we can compete.’ Then you talk to the iBuyer, and they’re like, ‘Nope, we do not want to go head to head,’” he said. That’s because, unlike with agents,“It’s all about price” when it comes to iBuyers.

When matching with agents, the site recommends multiple agents.

But when matching sellers with iBuyers, it only recommends and requests an offer from a single iBuyer at a time out of sensitivity to their preferences.

Why iBuyers don’t like iBuyer aggregators

IBuyers generally aren’t eager to discuss iBuyer aggregators. But when pressed, they tend to emphasize that homeowners receive a better experience by engaging an iBuyer directly.    

Offerpad said in a statement that it has not formed a relationship with any aggregators because none “produces a better experience for buyers, sellers, and agents than that found when they come directly to Offerpad.” At the same time, the company said it would “welcome” a standalone aggregator that lets consumers independently obtain and compare bids from multiple iBuyers in side-by-side comparisons similar to Zillow’s now-shuttered Instant Offers – “if such a service existed.”

Opendoor declined an interview for this story but did note in a statement that it had “agreements with certain service providers that feature our offers exclusively or on a preferred basis.” These providers include, as well as Redfin, iBuyerConnect and MoxiWorks – all of which let agents present Opendoor offers alongside comparative market analysis in listing appointments.

Zillow spokesman Viet Shelton said that Zillow does not provide offers to third-party aggregators because Zillow Offers is not meant to be a “source of lead generation,” a reference to the tendency of many aggregators to convert iBuyer inquiries into traditional listings. He also said that working with a seller directly from the get-go was the best way to deliver “the best consumer experience and transaction possible.”  

“You shouldn’t be able to make the claim of another company’s offer if you don’t actually know what the offer is going to be,” he added, referring to the iBuyer offer estimates generated by some iBuyer aggregators.

But estimating how much a specific buyer would pay for a home, some industry observers point out, is not so different from estimating what a home would sell for on the open market — which is what Zillow does with its Zestimates. 

Mike DelPrete, a real estate tech consultant who recently joined Zavvie’s board, compares iBuyer offer estimates to “the Zestimate 10 years ago.”

 “It’s an interesting starting point, but it shouldn’t be taken for a serious offer on your house,” he said. 

Offerpad also expressed a similar concern to Zillow: that “so-called comparison services” would represent their estimates of iBuyer offers as real offers while falsely “implying a partnership or endorsement with Offerpad exists.”

DelPrete also noted that iBuyers want to avoid paying for access to customers that they could otherwise attract directly. Standalone iBuyer aggregators “either would dilute the offer price the seller is going to net, or it’s going to cost the iBuyer more money,” with the aggregator charging a fee, added Noma, the broker and co-creator of iReal Estate Pro.  

The certainty that iBuyer marketplaces would drive even more pricing competition, particularly those that present iBuyer offers side by side, is another reason iBuyers are leery of aggregators, according to Woods, the CEO.

“They’re trying to make it ambiguous, so that there’s confusion, so that there’s a level of salesmanship where they can just lure you in, even if their bottom line isn’t quite as good as the next guy’s,” he added about iBuyers. 

Another source of tension is that iBuyer aggregators can undercut iBuyers’ “one-stop shop” strategy of providing ancillary services such as mortgage and title services. 

“If you’re not the first place a consumer goes, you lose that,” DelPrete said.

The one aggregator iBuyers are cool with

Despite all of this, iBuyers are comfortable with one form of aggregator who often does grab and present their offers in side-by-side comparisons: the real estate agent. 

One reason for this is that agents submit offer requests with more accurate property details. This limits the need for follow-up communication and tends to lower the repair cost credits that the iBuyer requests from the homeowner, according to Noma. This, in turn, can help iBuyers fight the perception that they bait and switch consumers, he said.

Another reason is that agents are a big source of direct revenue for iBuyers. iBuyers connect with many sellers whose homes are outside their “buy box” or who reject their offers. iBuyers can earn tons of referral fees by pairing these sellers with partner agents.

“They still need agents today, and agents are part of the economic engine that powers the iBuyers and the seller lead gen and the buyer lead gen,” said Cofano, the Seattle-based broker. “It’s not that [iBuyers] want them to be doing [aggregation], but I think they don’t fear [agents] because they’ll never aggregate at scale, and that’s the biggest risk.”

But if popular standalone aggregators do emerge, agents and brokerages will likely play a key role in their operation, according to insiders. Some, such as Zavvie, have shifted to providing back-end tools for agents. But it’s not difficult to imagine such services launching standalone websites for consumers.  

“I absolutely believe that an industry player will try to build iBuyer aggregation, whether that’s purely through their individual agents or through relationships with iBuyers,” Cofano said.

In the meantime, McLennan says that ExitNest will try to bob and weave its way to success, in spite of the iBuyers’ efforts to thwart the company. 

“As more iBuyers enter the market, they are anxious to work with aggregators to take market share from the Big 3 [Zillow, Opendoor and Offerpad],” he said. “As they gain traction, I imagine the larger iBuyers will feel the FOMO effect and get on board.”
