Data Quality

The Data Quality Dashboard provides real-time insights into the coverage and completeness of mortgage and real estate listings data across the United States, empowering members to make informed decisions based on actual data quality metrics rather than assumptions about market coverage.

High-Level Data Quality Metrics

Select Mortgage Coverage or Real Estate Listing Coverage to see that data and map change in real-time. 

The dashboard's overview section delivers four critical performance indicators:

• Population Covered – Percentage of the U.S. population residing in counties with comprehensive mortgage or listings data coverage
• 12-Month Record Count – Total volume of mortgage and real estate transactions captured across all counties over the past year
• Average County Lag – Typical delay in days between when activity occurs and when data becomes available in the system
• Overall Status – Simplified health scorecard using categories like "Excellent," "Good," or "Needs Attention"

Interactive U.S. Coverage Map

The visual centerpiece features an interactive map with several key capabilities:

• Color-coded display at the county level (green = strong coverage, red = weak/missing coverage)
• Hover functionality to view detailed metrics for specific areas
• Zoom capabilities for exploring regions in detail
• Quick visual identification of market opportunities and coverage blind spots
• Toggle between Coverage vs Lag views to show either data completeness or timeliness

Coverage Data Table

The data table provides granular insights with the following metrics:

• Mortgage Count – Total number of mortgage transactions recorded for each geographic area
• Coverage Percentage – Portion of expected market activity captured, typically measured against FDIC reported loans
• Lag (in days) – Time elapsed since the last recorded transaction for each area
• Status – Quality categories like "Excellent" or "Poor" for easy prioritization
• Toggle functionality – Switch between County vs. State views for different analysis granularity
• Filters and search options – Quick location of specific markets and pattern identification

Listings vs Originations vs 30-Year Rate Trend

This integrated time-series chart displays three critical market indicators:

• New Real Estate Listings – Tracks market supply side activity
• Mortgage Originations – Represents actual lending activity and demand
• 30-Year Fixed Mortgage Rate – Shows correlation between interest rates and market activity
• Trend analysis – Enables identification of market cycles, seasonal patterns, and rate impact
• Campaign timing insights – Helps optimize marketing efforts based on market conditions

FAQ

Q: Why don't I see real-time data for all counties? 
A: Some MLS boards and counties have policy or legal restrictions that prevent real-time reporting. Data availability depends on local regulations and the specific agreements we have with each data source.

Q: Why does coverage vary so much between different regions? 
A: Coverage percentages are influenced by regional data availability and partnerships. As we continue onboarding new data feeds and establishing relationships with additional sources, coverage will improve over time in underserved areas.

Q: The recent weeks in my charts look incomplete. Is this a system issue? 
A: This is normal behavior. Recent weeks may appear incomplete because records are still being received and processed from various sources. Data typically stabilizes and becomes more complete 2-3 weeks after the activity period.

Q: I'm seeing uniform values for Buyside/Listside coverage. Is this accurate? 
A: We've identified this as a potential bug and are currently investigating the issue. This should not reflect actual coverage variations and will be addressed in an upcoming update.

Q: How often is the dashboard data updated? 
A: The dashboard provides real-time visibility, with data refreshed continuously as new records are received from our various data sources.

Q: What does "Coverage Percentage" actually measure? 
A: Coverage percentage represents the portion of expected market activity we capture compared to benchmark sources like FDIC reported loans. A 100% coverage rate means we're capturing all expected activity for that area.

Q: If I see poor coverage in my market, what should I do? 
A: Contact your customer success representative to discuss potential data enhancement options for your specific market. We're continuously working to expand coverage and may have solutions in development for your area.

Q: How should I interpret the "Average County Lag" metric? 
A: This shows the typical delay between when mortgage or real estate activity occurs and when it appears in our system. Lower numbers indicate fresher data, which is generally better for prospecting and market analysis.
