MLS Data Standardization

Normalized MLS data to drive your real estate technology.
Standardized. Hosted. Served.

WolfNet accesses MLS listing data from over 600 MLSs, standardizes the data and then provides it to approved real estate technology companies for use within their products. With coverage in all 50 states and 97% of all active listings, we’ve got the data you’re looking for.

Need a Data Partner? We've Got What You Need.

Any real estate company accessing data from multiple MLSs faces a flood of challenges in standardizing and maintaining data and photos. There is little consistency with data schema, format, delivery, updates and photos. What many technology providers don’t realize is the contracting process to get this data from the MLSs can be just as daunting.

We manage the data and process, so you don’t have to. By doing this, we warp speed your time to market while saving you valuable IT resources.

The Data Access Pipeline

How we do it: First we access the MLS data via RETS, FTP Pull, FTP PUSH and direct database access. We then standardize the data by placing each characteristic into one of more than 400 standardized fields. Finally, we refresh the data throughout the day providing one of the most accurate and up-to-date MLS data sets in the world.

Photos are far and away the stickiest wicket for companies accessing MLS data. Bandwidth and the resources required to download, manage, and store photos strains IT – but not with WolfNet Data Services. There’s no need to download photos. Instead, you’re able to access photos via media servers in the cloud through URLs. We use a CDN which caches every photo to the location nearest to you for incredible speed and performance (we serve up well over 10M photos daily). But of course if you need to download photos, that option is available too. We always offer the highest resolution photos available. And we make it even more convenient by generating and providing thumbnail images that are perfect for results pages, mobile views and more.

How you do it: You have 24/7 access to the most updated MLS data available by direct database access or via API. Either way, you can easily automate your updates to keep your data as fresh as you like.

What Our Customers Are Saying

  • Ben Kinney

    “When you’re providing a solution to tens of thousands of agents, you need to have a company that’s always up, that doesn’t have down time, and that’s available to handle the issues that happen in technology so that the agents can keep doing their job, which is selling real estate.”

  • Victor Lund

    “A lot of people can provide IDX data services to real estate brokers, but very few can normalize that data across multiple markets and deliver it consistently. You have to have a reliable service that’s delivered to agents and that agents can use to service their customers. You need a company that’s going to do it every day all day long and never break.”

  • Lanny Baker

    “WolfNet plays a key role in our overall equation. We pride ourselves on having really accurate, timely and complete information about real estate listings and WolfNet is the keystone in the data arch getting the info from the MLS dropped into our consumer experiences on the web.”

  • Brad Blumberg

    “Data Provisioning services from WofNet have allowed Smarter Agent to provide cutting edge mobile technology in markets we could not otherwise access in a timely basis.”
