The real estate field is one of the most rapidly growing ones. Tech startups have changed the way consumers used to buy and sell a property. Their influence is obvious, 51% of homebuyers in 2017 purchased the house they found on the Internet. What does it mean for developers? As competition is on the rise, you have to be ready for delivering more complicated products in tight time frames using real estate API and other related tools. 

The following housing data API and tools can assist you in solving most of the technical problems:

  • Rets.ly
  • SimplyRETS
  • Data Rabbit API (Rets Rabbit)
  • Zillow
  • Realtors Property Resource API
  • Data.gov
  • Points of Interest API
  • Walk Score
  • SchoolDigger API
  • Google Maps API
  • Yelp Fusion
  • Zillow Mortgages APIs
  • DataNerds Property API

The above realestate API list comes to the rescue to save your time and help you meet those deadlines! In this article, we list the most useful of them and shed some light on how to deal with real estate databases. Moreover, you'll find out more about what is API in real estate.

What is API in Real Estate: Essence and Benefits

To dig deeper into the subject, let's clarify, what is the API, and how it'll help you in building the digital solutions that will simplify your real estate business activities.

Application Programming Interface (or the API in short) serves as the software mediator enabling two applications contact each other. It typically contains protocols and terms which help the developers create software and integrate it with one another.

The most distinctive feature of APIs is clarity. James Gosling emphasizes it in the following manner:

An API that isn't comprehensible, isn't usable.

Let's consider the APIs' other features in details as well as the notion of the real estate API.

API discoverability means that the user may learn how to use it naturally. It's also crucial for developers to figure out which of your API services they require.

Consistency is also critical for API , as you'll be able to streamline your development processes, lowering the risk of developing and deploying APIs by ensuring this feature.

Documentation. Someone newcomer will need to examine and work with your API. You'll want to make sure it's recorded in a consistent and easy-to-understand manner.

Accessibility. APIs must be developed in a way that encourages users to engage with them. A simple API with fewer features will be more successful than a complex one with more features.

After we checked the crucial features the efficient API should have, let's narrow our research and find out what is API used for in real estate. Let's get acquainted with the following definition:

A rental property API transports property listing data from the Multiple Listing Service (MLS) to an agent website or real estate application. Real estate APIs are efficient and quick, obtaining data as needed and saving money on hosting.

Property Data API: It All Starts With Information

Before we continue talking about APIs, we should mention that much of the article rather covers the US housing market (API sets are also offered for this country), but it's still useful for software developers working on real estate projects with the focus on any country in the world.

Where Does Real Estate Data Come From?

Before you begin designing a product, you should first evaluate the data source. As with any real estate application or website, certain types of information are required, varying from a set of possible properties for sale or rent to neighbourhood data, you should definitely answer the question 'Where can I get that data from?' We're here to help you, though, offering real estate search API lists at your service further. However, the answer is dependent on how you or your customer intends to promote the product: locally or globally.

Such US business as Zillow gets the data from various feed sources which you can see below:

  • Listings manually posted by users and marked as 'For sale by owner'.
  • Listings manually posted by agents.
  • Zillow gets listings directly from an MLS in some cases.

There are some more variants when listings are sent directly to Zillow by:

  • Partners;
  • Brokers (Realtors);
  • Agents;
  • Third-party 'feed' providers (as the company calls them). 

Let's stop on MLS for now. This acronym stands for Multiple Listing Service. A community of realtors uses it to look at each other's available property listings. Realtors gain from providing this information since they receive not just the commision but also valuable information.

As you understand, MLSs are a valuable source of information. With their help, the solution you develop will have something to offer to customers right off the launch. The challenge is that they can be difficult to find, even though some MLSs allow large real estate portals to republish their feeds, such as the referenced Zillow. Fortunately, we've discovered different real estate listings APIs that may be able to assist you in resolving this issue, which we'll go over in more detail later.

What about other countries except for the US? You're likely to face the same options for accessing the real property data (through API for real estate listings as well). Additionally, you might have to work with legal institutions in some regions.

However, MLSs seem the most convenient option as they are present in some European countries like Germany (e.g. Immowelt, Immobilienscout 24).

How to Implement MLS Into Your Product?

You must first establish the Internet Data Exchange before you can perform a data exchange between your product and the MLS. There are a few options for doing so:

How MLS integration works without API realty

How MLS integration works

FTP Protocol Goes First

Use the FTP protocol. This is a very inefficient approach which requires transferring complete datasets. In other words, the entire set of data has to be downloaded and then compared with a local duplicate to generate a certain query.

The Necessity of Real Estate Transaction Standard

Apply to the Real Estate Transaction Standard. This is a framework created to make the sharing of MLS data easier. Unlike FTP, REST is a more effective and convenient option that comes with a range of open-source tools that support a number of languages, which is a significant benefit for software developers.

Think About The Third-Party Services to Integrate

Use third-party services like real estate MLS APIs and plugins that can help your product normally interact with listing services. As we'll discuss real estate APIs a bit later, here are a couple of WordPress plugins you can use for a website: WordPress IDX ($39-$69 a month + $99 for a setup), IDX Broker ($39-$69 a month + $99 for a setup).

Remember, you'll need a strong server-side for your software solution to manage this data and provide stable work. That's why consider hiring a dedicated software developer to your team in case you don't have one yet.
