How to Make an App/Website like Zillow and Opendoor

08 February 2023 • 23 min read

The United States’ real estate earnings will surpass $395 billion in 2023, making the country no. 1 in the global real estate market. Since market revenue is expected to increase by 2.15% per year from 2023 to 2025, several businesses want to develop an app like Zillow. The latter is a service leading in America’s digital real estate, with $9.63 billion in income and 236 million users.

Americans today are more dependent on digital tools than ever before, in addition to traditional methods of buying and selling homes. In 2020, more than 60% of home buyers and sellers used electronic document signing, and in 2021, 79% of Americans showed interest in 3D virtual tours and digital floor plans. According to the 2022 report, 60% of sellers stated that including a virtual tour in their home listing is very or extremely important. An even larger share of 76% said that including a floor plan in their home listing was a highly important listing characteristic. With technology-friendly millennials entering the real estate market, digital tools are needed more than ever.

Today Zillow and Trulia, two of the most popular real estate apps, are moving quickly to meet this growing demand — and so are many entrepreneurs.

But how do you create your own marketplace app like Zillow? Or develop a real estate web platform like Trulia or Zillow?

The Softermii team has lots of cases developing such platforms in our portfolio. We know exactly how to build a real estate website, or develop a marketplace application like Opendoor, Trulia, or Zillow, quickly, efficiently, and professionally. This article covers this growing digital marketplace and shows how you can build a real estate listing app.

We’ll also look at how much it might cost to develop an app like Zillow or Opendoor and how long it might take.

Millennials Are Driving the Real Estate Market

Before we learn how to build a website like Zillow, it’s worth talking about who drives the market. Today, millennials represent the largest generational group in the United States. According to Opendoor, they’re quickly becoming the newest generation of home buyers.

Statistics of buying houses using an online app service

According to Opendoor’s research, 83% of millennials are more likely to purchase a house using an online app or service.

Typical age of current homebuyers

Zillow’s research predicts that 6.4 million new residential homes will be on the market by 2025 to accommodate the surge of millennial buyers. As a result, real estate technology will be used more than ever.

According to the same research, millennials are comfortable making large purchases over a digital platform. Nearly 60% of millennials are confident enough to buy a home they’ve only virtually seen. Almost 40% are completely comfortable buying a house online.

Time-saving digital tools will allow first-time buyers to reach their goals in a highly competitive and fast-paced industry. It will also allow sellers to sell their homes faster than ever. Based on Zillow’s data, homes with a 3D tour got 29% more views, were favored 32% more often, and sold 10% faster than homes without a virtual tour.

As millennials want more digital shopping tools for their real estate experiences, the demand grows, and the market becomes more profitable.

Real Estate Website, Application, or Both?

What’s the best platform to promote your business: an application, a website, or both? Let’s find out.

So, you have decided to build a real estate website like Zillow. What are the benefits for your buyers and sellers?

  • Loyal target audience
  • Convenient system to find clients and properties
  • Opportunities for better targeting
  • Interaction between buyer and seller is convenient without intermediaries
  • Search by geolocation for a better real estate search
  • Review and rating system to help you choose your agent or seller

Real estate search websites like Zillow also benefit real estate agents. Such sites simplify the work of realtors and give access to advanced analytics and better targeting. In addition, the sites’ marketing tools help agents market their services effectively.

A good real estate site also protects all parties from fraud. That’s because properties are heavily moderated.

Another reason users choose real estate websites is convenience. You don’t have to install multiple apps on your smartphone to use them to compare offers.

A real estate app presents all the same benefits as a website. However, the app’s architecture allows for a more thoughtful design, notifications of hot deals, and messages. Sellers and buyers are more comfortable chatting in the app than constantly updating the website. Therefore, when answering the question of how to build a real estate app or a website, it is difficult to choose.

When deciding between a website and an app, base your choice on the needs of your target audience, available resources, and finances. If you have an unlimited amount of money, it’s ideal to use both: the app and the website.

Zillow and Trulia’s New Features

Zillow and Trulia have been quickly working to accommodate the millennial market. In 2020 and 2021, they implemented the following features:


This feature allows for the automation of the showing, scheduling, and managing real estate process for realtors. Buying agents can book viewings faster than ever, and listing agents can easily approve scheduling requests over Zillow. With ShowingTime, it creates a seamless and simple transaction that is both efficient and easy.

Zillow Surfing 2.0

Zillow updated its virtual tour experience and created a more authentic showing by combining different media content and technologies. Interested home buyers can now view specific room dimensions and the camera’s exact location on an interactive floor plan and get a more in-depth tour.

Surfing feature in Zillow-like app

New Search Filters

Trulia understands that an advanced search engine is essential to a real estate application, so it recently added new filters. Users can now conduct more detailed searches and receive a simple list of apartment types that meet their categories.

Faster Contact

In an overly competitive market like real estate, sending and receiving time-sensitive messages can make or break a deal. As a result, Trulia has simplified its contact forms, so interested users can quickly connect with listing agents.

Hide Homes

Zillow implemented this feature at the request of its customers. This functionality helps significantly speed up the housing search, as users can prevent excluded houses from showing up in their future search results.

Is It Worth Completely Copying Features of Zillow or Opendoor?

Our article is not intended to encourage you to copy the features of real estate apps like Zillow completely. This platform is just a great example of where to get inspiration from, just like Opendoor. Nevertheless, you shouldn’t limit yourself to these two real estate applications while generating concepts for your own software solution.

You can explore the features of other popular Zillow’s competitors. In particular, these are such real estate platforms as LoopNet,, and Zumper.

Remember that duplicating an already viable product is not your way to success. Here, a profound grasp of your target audience and providing exceptional or better features that your competitors lack are crucial.

As for the basic features of real estate applications, they are usually the same across all platforms. Read on to learn more about them.

Must-Have Features for a Real Estate App like Zillow

Let’s see what fundamental features you require to make an app like Zillow.

Expansive Database

It is crucial for real estate apps and websites to have a database that is large enough to store thousands — even millions — of listings. For example, Zillow’s database has over 110 million listings in the United States, which translates to over 110 million potential business deals.

Your database will depend on the MLS system for listings, but you can also allow user contributions. To accept independent listings, you should have a basic form to gather information about the property, such as photos, descriptions, and price.

Advanced Search Functionality

Users should be able to search for listings that fit their criteria. Some must-need filters should include location, property type, price range, and square footage. It is recommended that you also implement the ability for users to save their searches and properties of interest. Not only would this retain users, but it can also benefit realtors, who could suggest listings similar to the user’s interest.

It is also advisable to integrate analytics to gather information on the most popular filters and search trends.

Informative and Attractive Listing Pages

To make an app like Zillow

Listings should use a combination of text and pictures. You will want to avoid long paragraphs and use graphs or photos to hold the user’s attention. Information such as a monthly mortgage breakdown, home values, and maps should be done visually.

Interactive Neighborhood Maps

A neighborhood map should display information based on important criteria, such as the availability of schools, stores, or other points of interest. It is highly recommended to incorporate a GPS into the app so users can also determine travel times between the listed home and important destinations, such as work, daycare, and family.

Virtual Tours

Build a website better than Zillow

Virtual tours are beneficial for both potential homebuyers and agents. Users can view homes whenever and wherever they want, while realtors can avoid hectic schedules. It is also useful for international users who cannot physically see the property in person.

Video Tours

Video tours are similar to virtual tours but are done in real time. An agent can walk through the home and give a more personalized tour. They can also answer questions and accommodate requests that cannot be done over a virtual tour.

Match Users and Agents

Potential buyers and sellers should be able to match with a real estate agent who fits their needs. It can be done with users reaching out to agents or vice versa.

Real-Time Messaging

Real estate apps like Zillow

Allowing users and agents to communicate with each other will increase engagement and the continued use of your app. Your app should, at the very least, have text messaging, but it is recommended that you also implement voice and/or video chat.

Features for Real Estate Websites like Zillow and Opendoor

Zillow, Trulia, and Opendoor have become market leaders in real estate thanks to features that make it easy to find and buy property. If you want to develop a real estate web platform like Trulia or Zillow, check out the following features:

  • Authorization
  • Listing page
  • Easy search
  • Quick view
  • 360-degree online tours
  • Online chat
  • Search properties by geolocation
  • Instant purchases

Convenient and Fast Login

Zillow allows you to register via Facebook or Google, which speeds up logging in many times. It’s incredibly convenient for building a real estate marketplace like Zillow. Users today don’t want to waste time registering and making up passwords.

Property Listings

This feature helps you quickly and conveniently filter and see all the objects of interest by price, location, etc. To build your own real estate app similar to Zillow, include this feature in your project.

Convenient Search

Websites like Zillow, Trulia, and Opendoor have a robust search system with multiple filters. This solution allows the buyer to maximize the search customization and find the property of their dreams without difficulty.

Fast Property Viewing

How to create a website like Zillow

Thanks to this feature, there is no need to spend hours and days personally seeing all the properties of interest. In just a couple of clicks, the user can study a detailed property description, see photos, and decide about the purchase.

View the Property Using AR Technology

A customer can take an online tour using 360-degree videos if photos aren’t enough. This solution gives an advantage over competitors and increases the chances of a successful deal.

Online Chat

Instant messaging lets buyers and sellers quickly get additional information on a property.

Map Integration

Searching for homes by geolocation allows you to choose the perfect home in the ideal location. It’s beneficial in densely populated areas when there are too many offers.

Instant Buying

Before building a real estate website like Zillow, note that Zillow experienced troubles with their property purchase solution. And Opendoor has benefited from it. The company recently introduced a new feature, iBuying, which has left Zillow behind.

Unfortunately, Zillow’s algorithms allow closing only through extended bidding, selling, and closing processes. Opendoor, on the other hand, offers property owners the ability to sell houses and apartments for cash online immediately. Keep it in mind if you build a website for real estate like Opendoor.

The Tech Stack You Will Need

When developing real estate websites similar to Zillow, you cannot ignore the tech stack. Creating a real estate listings website from scratch is not simple. To manage large amounts of data, you will need a robust backend. We recommend the following tech stack for building a real estate marketplace like Zillow:

  • Development Language: Java and Python
  • Cloud Hosting: Amazon EC2
  • Cloud Storage: Amazon S3
  • Version Control: Jenkins
  • Data Management: Real and CoreData

For the client side, you will have to determine which platform you will use for your app. For Android, you can use Kotlin or Java; for iOS, you can use either Swift or Objective C.

Additional APIs that you will need to provide geographical and neighborhood information to your users will be Google Places, SimplyRets, CoreLocation, MapBox, and CoreData or Mapkit.

And to build your own real estate website like Zillow with trending features, you might want to use the Facebook SDK (social media sharing capability). You can connect Firebase SDK and Apple Push Notification for the push notifications feature.

Tech Trends to Make the App Better Than Zillow

Learning how to create a website like Zillow is one thing. Making your real estate platform unique is quite another. So what can you do to build a website better than Zillow? Consider these latest technologies for your software solution:

Virtual Reality

Make real estate property tours even more immersive using virtual reality technology. You can enable realtors to sell houses remotely, and buyers, in turn, visit their dream home in a virtual environment and view it in great detail.


While blockchain is associated with cryptocurrency for many, that’s not the only use case of this technology. It actually has a lot to do with real estate. This tech can secure and verify transactions and help with safe property data storage and exchange.

Digital Twins

Imagine that a tenant or a homebuyer can explore the property in subtle detail just from their laptop or smartphone. It becomes possible with digital twin technology, which involves the creation of exact digital 3D copies of real housing.

How Much Will It Cost to Build an App/Website like Zillow?

The process of developing a real estate website is complex and costly. It is not only because of the different APIs you have to integrate. To build a real estate listings app/site like Zillow, the development team must consider all the user groups: buyers, sellers, and realtors. Think about which features your service exactly needs so that you can save time and money.

How much will it cost to build a real estate website like Opendoor? What will it cost to build a website like Zillow? And what will it cost to create a real estate app like Trulia?

The final costs of a real estate app development can depend on various factors, such as product complexity and the number of overall features.

Furthermore, the size of your development team can also influence the price. However, the typical employees and factors that will determine the final costs are:

  • Project Manager
  • UI/UX Designer(s)
  • Frontend Developer(s)
  • Backend Developer(s)
  • Android/iOS Developer(s)
  • Business Analysis
  • Quality Control
  • Post-Release Maintenance

A basic and simple solution can be priced from $25,000 to $45,000. However, more complex real estate apps, such as those above, can cost upwards of $70,000. Let’s summarize the price in the table below.
