The story behind Zillow’s success 

The Zillow story began in 2004 when two former top Microsoft managers, Lloyd Frink and Rich Barton, joined forces to launch a website that could estimate a home’s value and rental rates for homes. The following year they launched a website with real estate data from 300 cities. In the first three days, a million users visited the site to “Zestimate” the value of their homes. 

Since its launch, Zillow has become something more than a property listing website since its monetization strategy includes running ads and promoting brokers and agents. As Spencer Rascoff, the CEO of Zillow Group says, “We are a media company. We sell advertising. Having a large audience is critical.” 

How does Zillow make money?

To earn money, Zillow provides users with the following promotion services:

Premier Services for real estate agents who pay the website for running ads and receiving leads. Agents are charged:

  • Cost per ad impression, i.e., the cost per 1000 ads views
  • Cost per lead varies from $20-60.

Selling Promotions aimed at real estate companies. The website charges property management companies cost per lead, cost per click, and cost per lease for running ads within the Zillow Rental Network, which includes AOL Real Estate, Trulia, MyNewPlace, Yahoo! Inc., Hotpads, and MSN Real Estate websites. 

The advertisement sales model includes selling advertising space to lenders, mortgage professionals, and other businesses. The platform charges a cost per lead fee. 

Subscription model for mortgage services, which means the website connects custom quote services and lead management platform.

The website includes unique features and tools that help buyers to find the perfect home,  real estate agents to promote their business. 

Now, let’s dive into the real estate website development process.

How to make a real estate website like Zillow: essential features 

As we can see, Zillow is the industry leader that others are trying to keep up to. However, it is almost impossible to duplicate  Zillow’s feature list without going bankrupt. According to an Aberdeen report, in 2018 alone, Zillow spent $20.8 million on technology. In view of this, we offer you to take you on your own path in the development of your real estate website. Below, we have gathered essential features for a real estate listing website MVP that will save time and stay within budget. 

Property listings and databases

Databases with properties are an essential feature for a real estate marketplace. If your real estate agency already has its database of properties located in your city, region, or country, the web development team will integrate it into the website’s back-end. But, if you have no databases, what should you do? Let’s find out.  

If you want to develop a real estate marketplace in the U.S., you can follow the Zillow example and integrate databases from:

  • National Association of Realtors (NAR)
  • Multiple Listing Service (MLS)

These sources of real estate databases list properties across the U.S., however, this is the most complicated option. You will receive access to MLS and NAR only if you get a real estate license in each U.S. state, which requires both time and money. Are there other ways to integrate property databases to a Zillow type website? Let’s see. 

  • Zillow API

You can integrate Zillow API to your website and get access to homes posted for sale. According to Zillow data and API Terms of use, the company allows integrating its API to websites, but not to mobile apps

  • Post by owners

Since you are going to develop a two-sided marketplace, you can allow landlords to place the information about their real estate for sale. 

  • Listing syndication platforms

You can enter the data-sharing agreement with one of the national real estate companies and list their property directly to your marketplace. To achieve that, you may choose among the following real estate platforms:

Filtering Algorithms

To allow users to find the property they are looking for more conveniently, you need to integrate a filtering algorithm to your marketplace. We suggest you consider the following search parameters:

  • Location 
  • Price

Mapping and geolocation 

Your marketplace users will want to learn about the area they are moving to beforehand. To achieve this, you can integrate Zillow API that contains neighborhood boundaries, and a bunch of other APIs with the neighborhood and geographical information, including:    

  • GeoNames, a dataset that includes over 10 million geographical names
  • Google Places API that provides info about local businesses, such as restaurants, sports clubs, and supermarkets
  • MapBox to build your custom map with property listing, market data, videos, and photos. This tool also allows users to draw a polygon on the map for better search results.

Cloud infrastructure 

Since your real estate marketplace will include a considerable amount of high-quality photos, videos, and even 360° panoramic images, to keep all this data you need powerful hosting. Otherwise, you will face issues with image system scalability, performance, and disaster recovery challenges. 

In this case, the best option is to follow Zillow’s example and integrate a cloud-based infrastructure from the very beginning. As for Zillow, the company uses Amazon Simple Storage Service (Amazon S3) to store over 100TB of data, over 1 billion objects, and 300 million images. “Maintaining an object count in the billions doesn’t work so well on a traditional file system. We would have to split those objects across many file systems, which would be a management nightmare. The scalability of Amazon S3 seemed like the right technology for us,” says Nick Michal, Unix systems engineering manager for Zillow Group.

Since you are now aware of the essential features of a real estate website, let’s find out how much it will cost. 


How much does a real estate website like Zillow cost

The development of a real estate website is a complex project, not only because of API’s integrations, but also because it includes different user roles, such as buyers, sellers, and admin. Therefore, the development team should build your real estate website for three types of users. To save you time and money, we recommend launching such projects as MVP, a website with only the main features. In this way, you can discover whether or not your business idea has to earn potential. Below, we have gathered the main features for building a real estate website MVP.

How to build the real estate marketplace with The App Solutions? 

Before we start making a real estate website MVP, we will launch the discovery (inception) phase, to explore and elaborate on the project idea. Moreover, we will also define the scope of the project and the possible solutions to be implemented. The main goal of the inspection phase is to identify the project’s scope and the requirements and create an Inception Technical Documentation, which may cost from $4000. 

Next, using technical documentation, the team will compose a list of requirements of MVP (Minimum Viable Product) features in the form of User Stories. The business analyst will clarify User Stories by splitting them into Use Cases Investigation and analysis of third-party system integrations. Then, we will start planning and projecting the future project MVP server architecture. When all these documents are ready, our team will launch the MVP development stage. 

The cost to create a real estate website MVP starts from $45,000, while the cost to build a real estate website with an integrated calendar, payment gateway, and other bells and whistles will cost from $100,000 to $200,000. 

However, the costs to develop a real estate app like Zillow are only approximate, because the final estimation of the real estate website will depend on website requirements and the number of features.
