How to Filter Out Properties from Other Countries Using Geographic Boundaries

Why Am I Seeing Properties from Other Countries?

If you're noticing properties from other countries appearing in your API responses, this is actually normal behavior. MLS® Systems don't have built-in geographic restrictions, which means agents can and often do list properties "out of area." This practice is quite common in the real estate industry.

The Solution: Geographic Boundary Filtering

The most effective way to keep your search results local and confined to your desired geography is to create a boundary using our map parameter with GeoJSON boundary support.

How It Works

When you define a geographic boundary in addition to your other search filters, our system will automatically exclude any properties that fall outside that boundary from your search results. This ensures that only properties within your specified area are returned.

Implementation

To implement geographic filtering:

1. Define your boundary using GeoJSON format
2. Include the map parameter in your API requests
3. Combine with other filters as needed for your specific search criteria

Benefits of Using Geographic Boundaries

• Keeps results local to your target market
• Eliminates irrelevant listings from other countries or regions
• Improves user experience by showing only relevant properties
