At the beginning of 2018, many sources simultaneously announced an increase in property prices in the US. In particular, this applies to such regions as Tacoma, Everett, and Bellevue, San Jose, California, and Raleigh, North Carolina. It is assumed that, on average, the purchase price of real estate will increase by 5.4 percent, while rent will rise in price by 3.5 percent. Rapid growth in the value of the real estate was observed already in 2017 and the trend persisted in 2018.

The fact that real estate is one of the most promising areas of business development, is evidenced by other data. For example, the growth of the average sales price of new homes sold in the U.S:

average sales price of new homes sold in the U.S 1965-2017

The growing number of new house sales and stable growth of rentals are also worth paying attention In the past few years, we have faced a worldwide trend in the digitalization of the real estate market. This trend sets certain rules that you need to follow if you want to make a profit.

One of the main trends is realtor app development. The pioneers in this area are Zillow and Trulia, which are among the largest players on the market today.

Why does a real estate business need an application?

Why does Zillow Group so popular in the Real Estate market?

Comparison of Real Estate Apps (Statistics)

As can be seen from the chart above, and the previously mentioned statistics, the undisputed leader among real estate applications is Zillow. It is slightly inferior to Trulia, which was bought by Zillow Group in February 2015 for $ 2.5 billion.

So what are the main reasons for the popularity of this application?

The convenience of use has great importance in promoting the application on the market.

Thanks to the search and filters, homebuyers can find a real estate object that perfectly matches their needs.

A map showing the location of the listings is a great way to give the user exhaustive information about the property of interest.

A better connection with potential buyers.

Zillow provides users with an excellent opportunity to contact the agent at any time to schedule showings. And also to leave feedback about cooperation with the agent, after the buying process is completed.

What are the main steps in a real estate application development

After you have chosen the functionality, it's time to start developing your future application. But do not forget about the pitfalls that may occur along your path.

Step 1: Multiple listing service database

According to US law, all public information about real estate must comply with certain canons. They are approved by the National Association of Realtors (NAR). This information is stored in the multiple listing service. MLS is a system in which brokers enter information about a real estate object and make a professional assessment of it to determine the actual value. A multiple listing service database does not have a public API, this information can not be accessed by an ordinary user or a person who wants to sell his house. Only brokers and listing agents have access. 

But nevertheless, NAR allows brokers to display limited information about real estate objects on their websites thanks to the system known as IDX or Internet Data Exchange.

MLS Database

IDX allows you to upload information such as price, property features, type of property. The downside is the fact that this system is practically not customizable. For example, if you want to change the design of the real estate catalog to fit your website, it will be almost impossible.

As you understand, in order to create a competitive position in the real estate market, you need to take care of where you will get the actual information about the listings. For today in the US, there is no single national MLS, instead, there are about 600 local systems.

You will ask: where do the big market players take the listings from? Some of them conclude an agreement with each MLS directly. Based on our experience, we advise startups to get access to the most extensive databases. For example, the California Regional Multiple Listing Service (CRMLS), the Arizona Regional Multiple Listing Service (ARMLS), and the North Texas Information (NTREIS). This will give you access to more than 100K listings and allow you to quickly enter the market.

Step 2: Advanced property search & filter

Creating a new real estate application is in a highly competitive environment, so we strongly recommend you make it as convenient and useful to the user as possible. If you have already completed the first step of our guide and determined what MLS you are going to cooperate with, then the list of properties in your database is huge. To help the user not to get lost in such a variety of houses, your application needs to contain a convenient and detailed search for real estate objects.

Property search on Trulia

The filter can be divided into:

Geographical feature

  • Index;
  • City;
  • State;

By price

  • Minimum price;
  • Maximum price;

By property type

  • Apartment;
  • Condo;
  • Multi-Family Home;
  • Single-Family Home;
  • Townhouse, etc;

By home features

  • Number of bathrooms;
  • Number of bedrooms;
  • Square feet;
  • Lot size;
  • Year of built.

In addition to a detailed filter, it is important to give users the ability to sort information by novelty (for example, from old listings to new ones), price (from low to high, and vice versa), by the number of rooms, lot size and so on.

Step 3: Detailed apartment features

Detailed information about the property will be no less important for the user's convenience. As we said earlier, certain information that has public access is uploaded from MLS.

But apart from this information, additional details are also important to users. For this, you can allow the listing agents to edit information about the property. It is also worth noting that the list of houses is not the only database that is used by traffic leaders in the real estate market. For example, Trulia provides information about the level of crime in the neighborhood. Crime Data can be obtained by API from a number of sources, for example from

Crime Data on Trulia

Zillow provides information about schools located in the neighborhood. This data is also pulled from the GreatSchools database.

Step 4: Interactive map

A common standard for real estate applications is the availability of an interactive map on which the user can get acquainted with the location of the listings. Objects on the map are marked with an icon. Clicking on it the visitor can see detailed information and a photo of the house. Such functionality is not only convenient but also allows to increase the user's involvement.

Interactive map on Zillow

For example, Trulia uses Google Maps API to easily and conveniently visualize important information for users, which they take into account when buying real estate. With the help of the map, visitors can see who lives next door, where the nearest park or mall is located. With the help of an experienced developer, you can add data on schools, public transit, nightlife, environmental and natural disaster risks, property valuations, and sales trends.

In addition, Map APIs will allow your application to work productively on all types of mobile devices and correctly displayed in the web version.

Step 5: Choose a model for monetizing your application in advance

We started this article with the fact that real estate in the US is a promising business nowadays. But in order to make the fastest possible profit from your application, we recommend you to think about the ways you are going to earn money in advance. Because it will influence the functional and technical characteristics of your future application.

There are several common models for monetizing a real estate application:

Special plans for listing agents and brokers

For this, your application must contain different user roles with different functionality. Brokers and listing agents will be interested in an extended profile with contact information, rating, and feedback from their customers.

Premium profile of listing agent

Advertising functions

The presence of an internal advertising cabinet is a challenge that requires a detailed approach in the development. Nevertheless, this is one of the most effective methods of promotion in the real estate market. Mortgage brokers will be interested in promoting their services, and listing agents will be happy to advertise a house that has been on the market for a long time.

Fee for additional features

A spread practice is to provide advanced functionality to users for a fee. Perhaps the broker will be interested to have a page with a unique template and description of services.

Detailed business analysis and quality development will help you determine the most effective monetization model, which will suit your business needs.

Step 6: Choose the right development technologies

Having thought about all the functionality and having determined the sources of databases, you come to the most interesting and the most difficult stage in the process of developing a real estate application: what technology stack to choose?

Speaking about the technologies used in the development of Zillow and Trulia, we can distinguish the following:

  1. Postgress, PostGIS SQL databases to handle a huge number of MLSs.
  2. Different APIs, such as SimplyRets, iHomeFinder, Spark APIs
  3. Facebook SDK - to log in using your account on the social network.
  4. MapKit - to create an interactive map that is customizable for your business needs.
  5. Firebase SDK and Apple Push Notifications Service for correct work of push-notifications.

The whole technology profile you can find on BuiltWith.

We would like to draw your attention to the fact that the target audience in the sphere of real estate is quite extensive. And in order to cover all its segments, we strongly recommend conducting multi-platform development.

Therefore, speaking of technologies, it can be mentioned that for the frontend it's best to use HTML5 and a JavaScript framework. JavaScript has a huge number of geo-focused libraries, such as Leaflet, which can greatly facilitate the development task. To customize advanced filters and sorts you need to implement JQuery.

We do not recommend using multiple database paradigms. The most effective way to store and manage property data and MLS data is to apply MongoDB. But MySQL / Postgres is also suitable for these purposes.
