Ever wonder why all the websites like Zillow, Trulia, Redfin, Realtor.com has the same property details? To get the information about all the properties we have to find a platform that provides the database for all the properties. We figured out that these data for the real estate market in the USA come from the different MLS (Multiple Listing Service) services. All these different MLS have their different data points and different ways to provide the data. Only with the approved license, one can ask for this data, and to get the license is not the problem. The challenging part is to exchange this data between the MLS database and your website, for which one has to implement the IDX (Internet Data Exchange) within its rules and regulations. To fetch the data from MLS and display it on the website, we implemented it with RETS, the XML based framework is used to access the data. With this, we can create the database and map the property fields from all different MLS services.

Property Data from Different MLS

All different MLS has its own method and way to provide the data exchange with the IDX rules and regulations. Fetch this large amount of data. When I’m saying large data, we’re talking in millions. Process the images and update the properties in no time when the agent updates this in MLS.

Property Data Mapping

All the states/ counties use the MLS as a real estate listing service but the different MLS are the different data types are there to match them for the database and later via data exchange display it on the website. Data points like property details, utilities information, 3rd party information against the property, images, routing and geo locating on Map.

Schedule Tour and Contact

The HouzQuest platform is not just only about displaying properties and their details, we needed to provide easy contact to local real estate experts and the functionality to schedule the tour of any property users liked with min response time and surety.

Advance Search

The challenge is to create an effective advance search that should let users quickly get the most relevant results quickly either they search for home address, street address, city, county or state.

Mobile Responsive

With the study for other business & relevant websites and as per the National Association of Realtors (NAR) 73% of users are from the mobile device, we knew that we needed the prominent solution to stand out in business with mobile responsive layout which should be fast, reliable and and should work with poor internet connectivity as well.

Image Processing

The main concern was to build a system that is fast, reliable and robust. With all the large images and millions of data we needed to find a way that system should load fast in any type of internet connectivity or even find a way to work offline.



To overcome the above challenges we made sure we’re building the system with latest and reliable technologies and created the decoupled server architecture so the components and instances are not dependent on each other and the system can work flawlessly in any situation. This helped us with the downtime as well. Because now if we make any major changes in the system/ add new modules or change in the database. There won’t be any downtime.

With custom development of a completely separate project of MLS using the RETS APIs and MongoDB we are able to add any new MLS with data mapping very seamlessly. The different AWS services like ElasticSearch, Redis Database the result to display when user search for the property or location became very efficient.

The all hardwork and dedication to develop the system that is user friendly and loads fast for desktop and mobile applications was alright and on the plan, but for mobile responsive usage we found an even better solution with developing the website as progressive web application using the advanced techstack.
