Clarifying Questions

• Looking at the current market dynamics, I'm thinking about the specific challenges in rapidly changing markets. Could you provide more context on what types of market changes we're seeing that are impacting Zestimate accuracy?

Why it matters: Determines if we need to focus on short-term price fluctuations or long-term trend shifts. Expected answer: Rapid price changes due to factors like sudden inventory shortages or economic shifts. Impact on approach: Would prioritize real-time data integration and more frequent updates.

• Considering Zillow's position in the market, I'm curious about the current perception of Zestimate accuracy. Do we have data on user trust levels or how often Zestimates are challenged by homeowners or real estate professionals?

Expected answer: Mixed perception, with some markets showing high trust and others showing skepticism. Impact on approach: Would influence whether to prioritize algorithm improvements or transparency and education.

• Thinking about Zillow's data sources, I'm wondering about the current lag time between market changes and Zestimate updates. How frequently is the algorithm currently updated with new data, and what are our primary data sources?

Why it matters: Identifies potential bottlenecks in data freshness and processing. Expected answer: Updates occur weekly, with data from MLS, public records, and user-submitted information. Impact on approach: Would guide decisions on increasing update frequency or expanding data sources.

• Considering the broader Zillow ecosystem, how does Zestimate accuracy impact other Zillow products or services, such as Zillow Offers or Premier Agent?

Why it matters: Helps understand the ripple effects of Zestimate improvements across Zillow's business model. Expected answer: High impact, particularly on Zillow Offers pricing decisions and agent-homeowner relationships. Impact on approach: Would influence the prioritization of improvements and potential integration with other Zillow services.
