## Known Limitations & Future Enhancements

### Current Limitations
1. **is_favorited**: Not implemented (requires authentication)
   - Infrastructure ready: field included in response
   - Implementation needed: User model + favorites table

2. **More Filters**: Hardcoded options
   - Can be made fully editable if needed
   - Currently: amenities, area, developer, completion_year

3. **Explore by City URLs**: Placeholder values
   - Editable in Filament admin
   - Populate with real URLs in admin panel

### Future Enhancements
- [ ] Add is_favorited with Sanctum auth
- [ ] Implement favorite/unfavorite endpoints
- [ ] Add inquiry/contact form submission
- [ ] Email notifications for inquiries
- [ ] Advanced search filters
- [ ] Save search preferences (auth required)
- [ ] Property comparison feature

---

## Performance Metrics

**Caching:**
- Project Data: 1 hour TTL (Goyzer API)
- Developers: 1 hour TTL
- States: Forever (rarely changes)
- Listing Page: Forever (clears on save)

**Response Time:** ~500-800ms (depends on Goyzer API)
**Data Size:** ~50-100KB per request (with 16 properties)
