O tomto rozšíření

See EPA hazard sites and FEMA flood zones on every listing — before you make an offer.

Deal Finder adds a small data panel to property listing pages on Zillow, Redfin, and Realtor.com. When you open any listing, it automatically checks two public government databases and shows you the results right on the page.

WHAT IT SHOWS
☢️ EPA Superfund & Hazard Sites — checks the EPA ECHO database for regulated industrial and hazardous facilities within 1 mile of the property address.
🌊 FEMA Flood Zone — retrieves the official FEMA National Flood Hazard Layer designation for the exact property location.

WHY THIS MATTERS
Most listing pages only show what the agent wants you to see. Deal Finder surfaces facts that are public record but hard to find:

A nearby industrial cleanup site can affect property value, air quality, and resale potential. A high-risk FEMA flood zone can mean mandatory flood insurance of $2,000–$5,000 per year on top of your mortgage — a cost that listings never mention.

Knowing these things before your showing — not after your offer — changes everything.

HOW IT WORKS
1. Install the extension
2. Go to any listing on Zillow, Redfin, or Realtor.com
3. A compact panel appears automatically in the corner
4. EPA and FEMA data loads within seconds

No account needed. No setup. Just install and go.

DATA SOURCES
All data comes directly from official US government APIs:
• EPA ECHO — Environmental Protection Agency facility and hazard data
• FEMA NFHL — National Flood Hazard Layer (official flood zone maps)
• OpenStreetMap Nominatim — open-source geocoding to locate the property

PRIVACY
Deal Finder does not collect, store, or transmit any personal data. The only information sent over the network is the property address (to geocode it) and the resulting coordinates (to query EPA and FEMA). No analytics. No tracking. No third-party ad networks.

SETTINGS
You can toggle EPA and flood data independently, set a default collapsed state for the panel, and optionally connect your Deal Finder account for future premium features.

/*
* Zillow Deal Finder
* ------------------
* Purpose:
* This feature helps identify real estate listings that may be priced below market value
* by comparing list price, estimated value, price history, days on market, and local comps.
*
* Core Logic:
* 1. Pull listing data from the source.
* 2. Normalize values like price, sqft, beds, baths, and location.
* 3. Compare each property against similar nearby homes.
* 4. Calculate a deal score based on discount, time on market, and resale/rental potential.
* 5. Return the strongest opportunities ranked from best to worst.
*
* Key Metrics:
* - List Price
* - Zestimate / estimated market value
* - Price per sqft
* - Days on market
* - Price history / reductions
* - Comparable nearby sales
* - Estimated cash flow or flip margin
*
* Assumptions:
* - Source data is reasonably accurate but may be delayed or incomplete.
* - A "deal" does not guarantee profit; users should always verify comps and repair costs.
* - Market conditions can change quickly, so results should be treated as leads, not final decisions.
*
* Risks / Limitations:
* - Zestimate and automated estimates may be off in some neighborhoods.
* - Missing repair cost data can make a property appear better than it is.
* - Comparable sales quality depends on distance, recency, and similarity of homes.
* - Some listings may already be under contract or outdated.
*
* Future Improvements:
* - Add filters for investor strategy: flip, rental, house hack, BRRRR.
* - Add neighborhood trend scoring.
* - Include rehab cost estimator.
* - Add mortgage, tax, insurance, and rent estimate modeling.
* - Save favorite deals and send alerts for new matches.
