Zillow is an online real estate marketplace matching buyers, sellers, renters, and landlords through a massive platform with personalized search and discovery experiences and simple UI for both buying/renting and selling/listing. The company makes money by charging a fee for sales and additional services like premium agents and mortgage services for buyers.
Origin story
Zillow is an online real estate marketplace founded in 2006 by Rich Barton, Lloyd Frink, Spencer Rascoff, David Beitel, and Kristin Acker.
It was former Microsoft employee and Expedia founder Rich Barton who would have the most profound impact on the formation of the company.
Barton noted that the real estate industry suffered from a high degree of information asymmetry.
Public housing data was difficult to access, locked away in various databases and archives. With this lack of transparency, realtors were able to maximize their profits at the expense of the consumer.
In the following years, Zillow would spend months collecting and digitizing housing data to make it publicly available on its website.
A feature allowing consumers to determine how much a property was worth caused the website to crash during the beta launch, attracting over 2 million hits in the first two days.

Zillow revenue generation

When Zillow launched in 2006, the company collected advertising revenue as the sole source of income.
Since then, Zillow has diversified into many income streams. We will take a look at some of these in more detail below.
Homes
Zillow has data on approximately 86% of the 128.5 million homes in the United States.
This data was incorporated into the Zillow Offers service in 2018. The service allows so-called “iBuyers” (instant buyers) to evaluate complex datasets to make near-instant cash offers to property sellers.
With speed and convenience a priority of most sellers, Zillow often purchases a property below market value. At some future point, it sells the property for a profit.
During the transaction process, Zillow also charges:
- A selling fee of 6% to cover the transactional cost of purchasing the home.
- A closing fee of 1-2% to cover expenses such as transfer tax, escrow, and title.
- An average service charge of 2.5% covering maintenance work, utilities, and so forth.
IMT
IMT is an acronym for Internet, Media, and Technology. To bolster its business model, Zillow offers marketing services and other products for real estate professionals.
IMT can be divided into three core components:
- Premier Agent โ encompassing the two SaaS products in Premier Agent and Premier Broker. These products allow agents and brokers to track leads or advertise their services on the Zillow platform. Here, Zillow makes money on a cost-per-lead basis which is determined by the services offered and the property price.
- Rentals โ where Zillow sell advertising services to landlords and associated rental professionals
- Other โ where Zillow sells similar services to individuals who play a role in the renovation or re-sale process. These include photographers, builders, home improvement professionals, and housing inspectors.
For the Rentals and Other components, Zillow is paid on a per-lead basis.
Mortgages
Through its Zillow Home Loans service, the company also makes money on mortgage interest.
The company also works with more than 50 other lenders who pay Zillow every time a customer is referred to them. This is usually a fixed fee depending on the nature of the agreement between both parties.
Cost structure
The cost structure is primarily skewed toward the resources to make both the desktop and mobile platforms (websites, and mobile applications) run smoothly. Together with part of the acquisition costs, that are critical to sell the homes in the first place (things like repairs and updates.
Cash flow generation

The company generated operating cash flows in 2020 primarily due to “cash received from real estate professionals, rental professionals, mortgage professionals, and brand advertisers, as well as cash received from customers for sales of homes through Zillow Offers and sales of mortgages originated by Zillow Home Loans.”
When it comes to investing activities, the use of cash primarily relates to “purchase and sale or maturity of investments, the purchase of property and equipment and intangible assets and cash paid in connection with acquisitions.
Instead of financing activities, incoming cash resulted from net proceeds from the issuance of convertible notes, net proceeds from and repayments of borrowings on for Zillow Offers, and proceeds from the borrowing of Zillow Home Loans.
Key takeaways:
- Zillow is an online real estate marketplace founded in 2006. Former Microsoft employee Rich Barton created the platform in response to a lack of transparency and disgruntled customers in the real estate sector.
- Zillow began with a simple business model, generating income solely from advertising. With data on 86% of all United States homes, the company has since progressed to allow a free and open transaction experience for buyers and sellers.
