+## PropertyMap (high-level SDK component) ✅
+
+`PropertyMap` is a ready-made map screen for property searches — it includes a search bar, clustering support, polygon rendering and a bottom property card. It's ideal to embed in apps that want a turn-key property map.
+
+Install the extra peer deps in your app:
+
+```bash
+npm install react-native-map-clustering @react-native-community/geolocation
+# and make sure react-native-maps is installed and configured
+```
+
+Basic usage:
+
+```tsx
+import React from 'react';
+import { PropertyMap } from '@lynkedup/map-sdk';
+
+export default function PropertiesScreen() {
+  return (
+    <PropertyMap
+      apiUrl="https://your-api/property-search"
+      initialRegion={{ latitude: 25.48, longitude: 81.85, latitudeDelta: 0.02, longitudeDelta: 0.02 }}
+      showSearch
+      radius={500}
+      onSelectProperty={(item) => console.log('selected', item)}
+    />
+  );
+}
+```
+
+Props summary:
+
+- `apiUrl?: string` — POST endpoint used for property searches (defaults to the demo host).
+- `initialRegion?: Region` — starting region.
+- `radius?: number` — search radius in meters (default: 500).
+- `showSearch?: boolean` — render search bar (default: true).
+- `onSelectProperty?: (item) => void` — callback for property selection.
