The Open Rent Initiative

A public good that addresses the lack of accessible, granular and timely rental market data for researchers, policymakers and the public.

Imagine visiting a doctor due to an ailment. To diagnose the issue, the doctor requires your blood work.

Instead of performing specific blood tests tailored to you, the doctor consults a tattered tome from their shelf. This book contains blood work statistics, gathered 3-5 years prior, from a bunch of other people. The doctor finds data based on profiles matching your age, race, gender, and perhaps a couple of other characteristics.

Based on this information, the doctor provides you a diagnosis of your likely illness and prescribes some medication to address it. 

Would you take those drugs? Neither would I. 

And yet, this is essentially what is happening across the US on rental housing policy. 

Talk to anyone working with rental data and they’ll tell you the same thing: the data we use to make critical decisions about rental housing markets is wholly inadequate. While we debate housing affordability and craft policy, we’re operating with a patchwork of incomplete, outdated, and inaccessible information, making poorly informed decisions that affect more than $100 billion of public resources. 

You can read more about this problem in our Rent Madness report. 

Introducing The Open Rent Initiative

The Open Rent Initiative, a collaborative effort to build a public good to address this problem, is a follow-up to that report. The initiative consists of three core elements: 

  1. Data Platform: At the heart of the initiative is an open data platform that will collect, clean, standardize, and integrate disparate rent and rent-relevant datasets into a single, reliable platform (e.g., parcel, rent registry, rental listings, modeled/estimated, Census, data partnerships). 
  2. Partnerships: Collaborative framework that enables open source collaboration and coordination with local and regional organizations and experts.
  3. Analysis and Data Tools: Production of analytical and data tools built with the outputs of the data platform, designed to meet the needs of researchers, government officials, policymakers, advocacy organizations and entrepreneurs. 

Through this initiative, the Open Rent Initiative aspires to: 

  • Enable New Avenues of Research. The platform enables study of complex longitudinal questions about neighborhood change, economic health, and housing stability that are currently difficult or impossible to study.
  • Streamline and Reduce Costs of Research. As a centralized repository, it eliminates redundant and costly data collection efforts undertaken by individual researchers and organizations that lack resources. 
  • Democratize Access to Rent Information. By lowering technical and financial barriers, the platform empowers a wider range of stakeholders to conduct data-informed research and advocacy.
  • Support More Effective Resource Allocation. By providing timely and granular rent data, the platform enables public and philanthropic funds to be targeted with greater precision.  

Working Together Towards Data Transparency

Already, our team has made important progress laying the foundation for the data platform, including creating standardized schemas and addressing geospatial unification across disparate data sets. 

We have also established important philanthropic and non-profit partnerships to begin work on our pilot locations in the coming months. Stay tuned for these announcements and more over the next several weeks!  

The lack of national rental data is too big a problem for any of us to tackle in isolation. We’re building the Open Rent Initiative as a collective effort, and we invite you to join us in creating the transparent, accessible rental data our communities deserve.
