6 Useful APIs to Find Data for Real Estate Platforms

The real estate market is evolving in leaps and bounds and willingly introducing innovative solutions. Among others, the time has come for its digitalization, which implies building web and mobile platforms allowing you to deal with a property online: sell it, rent it out, buy it, analyze it and even invest in it.

If you, too, want to contribute to this trend and create a similar platform, you have to find your own way to obtain the most relevant real property data. There are a lot of suitable options to achieve the goal but the smartest thing to do is to use special real estate data APIs.

Interested? Then we think it would be appropriate to delve into the issue and investigate it properly, point by point.

Why do we need access to real estate databases?

Before we figure out how to integrate real estate APIs or data into our mobile or web platform, let's discuss why property information is needed at all. How can you use it, to begin with?

The answer, in fact, is obvious: real property data would come in handy if you intend to build an advanced resource aimed at a few target groups (take a look at the picture below!).

real estate data APIs

All these users would resort to real estate portals if they need help in such areas as:

  • Learning detailed data on a specific property. That is, if a real estate agent (or a future tenant) wants to find out all the details about a particular object, he can take advantage of the services of a special property resource and get the following information:

    • The characteristic of the city block in which the property of interest to the user is located: the risk potential of natural perils, the type of schools nearby, the level of criminality, etc.

    • Information about the object itself, such as date of construction, market value, condition of the property, etc.

    • Ownership data.

  • In-depth analysis of the real estate industry. People who buy, rent, or sell housing will be satisfied with the information on a property, but this is not enough for investors. They should know the state of the modern property market and be able to predict its most probable development. Only in such a case, the investments made by them will pay off. Fortunately, the platforms we’re talking about can help investors conduct a study of the market situation, compare various property objects, and make a full analysis.

  • Effective marketing. Lastly, real estate databases are especially good at bettering marketing techniques. It’s quite understandable: with access to the latest information on market conditions and customer preferences, property companies can develop the most effective strategy.

Where to find real property data?

Now it's time to proceed to a more pressing question, namely: what is needed to make these resources work efficiently? Surely, first of all, the most accurate, most relevant real property data are required. But where to get this information?

Start by deciding how far you intend to go with your site, how big your plans are: will your platform be limited to only one country or will it be available in different parts of the world? 

The first option, of course, is easier to implement. And if you aim to cover the whole world, then the task becomes more complicated.

web development
If you're interested in building the real estate property listing management system, you have to hire a highly qualified team with huge experience in web development. Click here to learn more.

Typically, information about the property is being obtained from various online lists published by real estate agents or proprietors themselves (if they’re willing to sell or rent out their apartment). Each country has its own list of this kind.

In the United States and some European countries, Multiple Listing Service (commonly known as MLS) is particularly popular. Using Multiple Listing Service, real estate agents share with each other important information on property objects (those that are currently available). And more to the point, developers are welcome to integrate MLS Databases into their resources... it's now so easy to do but there are a few ways to simplify the whole process. Of course, we mean the possibility to resort to real estate data APIs.

What is API, to begin with?

To begin with, we'd like to sort out the concept of API (which means Application Programming Interface). What it is? Why do we need it?

As the name says, the API is a special interface providing developers with the opportunity to significantly simplify their work of creating applications and sites. The simplification of the development process is due to the fact that the API allows using ready-made blocks of code (sets of classes, procedures, functions, etc.).

Many large resources (the same Facebook, Google Maps, PayPal, and so on) open access to some of their services and databases, and they do this by providing API keys (such access can be either paid or free).

These are the so-called third-party APIs. Among the instances are the following options:

  • logging in with your personal Facebook account;

  • displaying a Twitter feed on your blog;

  • the display of custom maps on web pages (here we’re dealing with Google Maps APIs or another similar service). 

If we’re talking about the property market, then the API opens access to large real estate databases. Typically, these bases are formed by market giants who are ready to share the information collected with developers (on paid or free terms).

Just imagine: a certain user is trying to find an apartment, and he has requirements for the future home he wants to rent or purchase. He opens the property website and enters the search criteria: the price of the apartment, the area of ​​its location, and so on. The web resource accesses third-party databases through the real estate APIs feature, receives the result, and passes it to the user. Everyone is happy!

developing a financial digital platform
Thinking of developing a financial digital platform? Pay attention to these useful finance APIs, which we describe in our article.

Okay, the reasons explaining why real estate APIs are so popular are clear: these solutions greatly speed up the work of developers. However, what to choose to create your platform? What options are there?
