Does anyone actually use public data to find markets before they move?

[Hassan Rashid]

Permits. Zoning applications. Transit announcements.Census migration data.All public. All free. All updated regularly. In my testing across Austin and Chicago, zip codes with 3+ of these signals firing in the same quarter appreciated ~28% over 18 months vs ~9% for those with none. I'm building a tool that scores every US zip code automatically based on these signals. Think Zillow Heat Map but 18 months earlier.Before I go further — does this solve a real problem for how you actually invest? Or do you already have a system that works? Brutal honesty appreciated.
