## Frequently Asked Questions

---

**Q: Encountering issues with your queries?**  
**A:** Try a single site and/or broaden the location. If problems persist, [submit an issue](https://github.com/ZacharyHampton/HomeHarvest/issues).

---

**Q: Received a Forbidden 403 response code?**  
**A:** This indicates that you have been blocked by the real estate site for sending too many requests. Currently, **Zillow** is particularly aggressive with blocking. We recommend:

- Waiting a few seconds between requests.
- Trying a VPN to change your IP address.
