Inspiration
The 2008 housing crisis is often oversimplified. We wanted to use real data to understand what actually happened, when recovery truly began, and whether all regions experienced it the same way.
What it does
Our project is an interactive Tableau dashboard that visualizes the collapse and recovery of the U.S. housing market from 2007–2017, highlighting lending trends, borrower behavior, and regional differences.
How we built it
We analyzed 13 million HMDA mortgage records across four states and used Tableau to create visualizations, including maps, time-series trends, loan composition charts, and a recovery index.
Challenges we ran into
We worked with large, complex datasets, cleaned and structured raw HMDA data, ensured performance in Tableau, and designed visuals that were both clear and insightful.
Accomplishments that we're proud of
We uncovered that the crisis lasted longer than commonly believed, showed how recovery varied across states, and built a compelling, easy-to-use dashboard that tells a complete data-driven story.
What we learned
We learned how critical data preparation is, how policy decisions impact market stability, and how powerful data visualization can be in challenging common narratives.
What's next for U.S. Mortgage Market: Collapse & Recovery 2007-2017
We plan to expand this project by including more states, integrating additional economic indicators, and enhancing predictive insights to help guide future lending strategies.
