25 | _Python version >= [3.9](https://www.python.org/downloads/release/python-3100/) required_ 26 | 27 | ## Usage 28 | 29 | ### Python 30 | 31 | ```py 32 | from homeharvest import scrape_property 33 | 34 | properties = scrape_property( 35 | location="San Diego, CA", 36 | listing_type="sold", # for_sale, for_rent, pending 37 | past_days=30 38 | ) 39 | 40 | properties.to_csv("results.csv", index=False) 41 | print(f"Found {len(properties)} properties") 42 | ``` 43 | 44 | ### Flexible Location Formats 45 | ```py 46 | # Accepts: zip code, city, "city, state", full address, etc. 47 | properties = scrape_property( 48 | location="San Diego, CA", # or "92104", "San Diego", "1234 Main St, San Diego, CA 92104" 49 | radius=5.0 # Optional: search within radius (miles) of address 50 | ) 51 | ``` 52 | 53 | ### Advanced Filtering Examples 54 | 55 | #### Time-Based Filtering 56 | ```py 57 | from datetime import datetime, timedelta 58 | 59 | # Filter by hours or use datetime/timedelta objects 60 | properties = scrape_property( 61 | location="Austin, TX", 62 | listing_type="for_sale", 63 | past_hours=24, # or timedelta(hours=24) for Pythonic approach 64 | # date_from=datetime.now() - timedelta(days=7), # Alternative: datetime objects 65 | # date_to=datetime.now(), # Automatic hour precision detection 66 | ) 67 | ``` 68 | 69 | #### Property Filters 70 | ```py 71 | # Combine any filters: beds, baths, sqft, price, lot_sqft, year_built 72 | properties = scrape_property( 73 | location="San Francisco, CA", 74 | listing_type="for_sale", 75 | beds_min=3, beds_max=5, 76 | baths_min=2.0, 77 | sqft_min=1500, sqft_max=3000, 78 | price_min=300000, price_max=800000, 79 | year_built_min=2000, 80 | lot_sqft_min=5000 81 | ) 82 | ``` 83 | 84 | #### Sorting & Listing Types 85 | ```py 86 | # Sort options: list_price, list_date, sqft, beds, baths, last_update_date 87 | # Listing types: "for_sale", "for_rent", "sold", "pending", "off_market", list, or None (common types) 88 | properties = scrape_property( 89 | location="Miami, FL", 90 | listing_type=["for_sale", "pending"], # Single string, list, or None 91 | sort_by="list_price", # Sort field 92 | sort_direction="asc", # "asc" or "desc" 93 | limit=100 94 | ) 95 | ``` 96 | 97 | #### Pagination Control 98 | ```py 99 | # Sequential mode with early termination (more efficient for narrow filters) 100 | properties = scrape_property( 101 | location="Los Angeles, CA", 102 | listing_type="for_sale", 103 | updated_in_past_hours=2, # Narrow time window 104 | parallel=False # Fetch pages sequentially, stop when filters no longer match 105 | ) 106 | ``` 107 | 108 | ## Output 109 | ```plaintext 110 | >>> properties.head() 111 | MLS MLS # Status Style ...
