## Installation

```bash
pip install homeharvest
```
  _Python version >= [3.10](https://www.python.org/downloads/release/python-3100/) required_ 

## Usage

### CLI 

```bash
homeharvest "San Francisco, CA" -s zillow realtor.com redfin -l for_rent -o excel -f HomeHarvest
```

This will scrape properties from the specified sites for the given location and listing type, and save the results to an Excel file named `HomeHarvest.xlsx`.

By default:
- If `-s` or `--site_name` is not provided, it will scrape from all available sites.
- If `-l` or `--listing_type` is left blank, the default is `for_sale`. Other options are `for_rent` or `sold`.
- The `-o` or `--output` default format is `excel`. Options are `csv` or `excel`.
- If `-f` or `--filename` is left blank, the default is `HomeHarvest_<current_timestamp>`.
- If `-p` or `--proxy` is not provided, the scraper uses the local IP.
### Python 

```py
from homeharvest import scrape_property
import pandas as pd

properties: pd.DataFrame = scrape_property(
    site_name=["zillow", "realtor.com", "redfin"],
    location="85281",
    listing_type="for_rent" # for_sale / sold
)

#: Note, to export to CSV or Excel, use properties.to_csv() or properties.to_excel().
print(properties)
```

## Output
```py
>>> properties.head()

## 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.
