Fix timezone handling for all date parameters

- Treat naive datetimes as local time and convert to UTC automatically
- Support both naive and timezone-aware datetimes for updated_since, date_from, date_to
- Fix timezone comparison bug that caused incorrect filtering with naive datetimes
- Update documentation with clear timezone handling examples
- Add comprehensive timezone tests for naive and aware datetimes
- Bump version to 0.8.3

-**HomeHarvest** aims to be the top Python real estate scraping library.
+**HomeHarvest** is a real estate scraping library that extracts and formats data in the style of MLS listings.
 
-## RoadMap
+- 🚀 [HomeHarvest MCP](https://smithery.ai/server/@ZacharyHampton/homeharvest-mcp) - Easily get property data in your agent.
+- 🏠 [Zillow API](https://rapidapi.com/zachary-l1izVlvs2/api/zillow-com9) - Get Zillow data with ease.
 
-- **Supported Sites**: Currently, we support scraping from sites such as `Zillow` and `RedFin`.
-- **Output**: Provides the option to return the scraped data as a Pandas dataframe.
-- **Under Consideration**: We're looking into the possibility of an Excel plugin to cater to a broader audience.
+## HomeHarvest Features
 
-## Site Name Options
+- **Source**: Fetches properties directly from **Realtor.com**
+- **Data Format**: Structures data to resemble MLS listings
+- **Export Options**: Save as CSV, Excel, or return as Pandas/Pydantic/Raw
+- **Flexible Filtering**: Filter by beds, baths, price, sqft, lot size, year built
+- **Time-Based Queries**: Search by hours, days, or specific date ranges
+- **Multiple Listing Types**: Query for_sale, for_rent, sold, pending, or all at once
+- **Sorting**: Sort results by price, date, size, or last update

-### Installation
+## Installation
 
 ```bash
-pip install --upgrade homeharvest
+pip install -U homeharvest
 ```
+  _Python version >= [3.9](https://www.python.org/downloads/release/python-3100/) required_
 
-### Example Usage
-```
+## Usage
+
+### Python
+
+```py
 from homeharvest import scrape_property
 
 properties = scrape_property(
-    location="85281", site_name="zillow", listing_type="for_rent"
+    location="San Diego, CA",
+    listing_type="sold",  # for_sale, for_rent, pending
+    past_days=30
 )
-print(properties)
+
+properties.to_csv("results.csv", index=False)
+print(f"Found {len(properties)} properties")
 ```
+
+### Flexible Location Formats
+```py
+# Accepts: zip code, city, "city, state", full address, etc.
+properties = scrape_property(
+    location="San Diego, CA",  # or "92104", "San Diego", "1234 Main St, San Diego, CA 92104"
+    radius=5.0  # Optional: search within radius (miles) of address
+)
+```
+
+### Advanced Filtering Examples
+
+#### Time-Based Filtering
+```py
+from datetime import datetime, timedelta
+
+# Filter by hours or use datetime/timedelta objects
+properties = scrape_property(
+    location="Austin, TX",
+    listing_type="for_sale",
+    past_hours=24,  # or timedelta(hours=24) for Pythonic approach
+    # date_from=datetime.now() - timedelta(days=7),  # Alternative: datetime objects
+    # date_to=datetime.now(),  # Automatic hour precision detection
+)
+```
+
+#### Property Filters
+```py
+# Combine any filters: beds, baths, sqft, price, lot_sqft, year_built
+properties = scrape_property(
+    location="San Francisco, CA",
+    listing_type="for_sale",
+    beds_min=3, beds_max=5,
+    baths_min=2.0,
+    sqft_min=1500, sqft_max=3000,
+    price_min=300000, price_max=800000,
+    year_built_min=2000,
+    lot_sqft_min=5000
+)
+```
+
+#### Sorting & Listing Types
+```py
+# Sort options: list_price, list_date, sqft, beds, baths, last_update_date
+# Listing types: "for_sale", "for_rent", "sold", "pending", list, or None (all)
+properties = scrape_property(
+    location="Miami, FL",
+    listing_type=["for_sale", "pending"],  # Single string, list, or None
+    sort_by="list_price",  # Sort field
+    sort_direction="asc",  # "asc" or "desc"
+    limit=100
+)
+```
+
+## Output
+```plaintext
+>>> properties.head()
+    MLS       MLS # Status          Style  ...     COEDate LotSFApx PrcSqft Stories
+0  SDCA   230018348   SOLD         CONDOS  ...  2023-10-03   290110     803       2

+[5 rows x 22 columns]
+```
+
+### Using Pydantic Models
+```py
+from homeharvest import scrape_property
+
+# Get properties as Pydantic models for type safety and data validation
+properties = scrape_property(
+    location="San Diego, CA",
+    listing_type="for_sale",
+    return_type="pydantic"  # Returns list of Property models
+)
+
+# Access model fields with full type hints and validation
+for prop in properties[:5]:
+    print(f"Address: {prop.address.formatted_address}")
+    print(f"Price: ${prop.list_price:,}")
+    if prop.description:
+        print(f"Beds: {prop.description.beds}, Baths: {prop.description.baths_full}")
+```

+    :param listing_type: Listing Type - can be a string, list of strings, or None.
+        Options: for_sale, for_rent, sold, pending, off_market, new_community, other, ready_to_build
+        Examples: "for_sale", ["for_sale", "pending"], None (returns all types)
+    :param return_type: Return type (pandas, pydantic, raw)
+    :param property_type: Property Type (single_family, multi_family, condos, condo_townhome_rowhome_coop, condo_townhome, townhomes, duplex_triplex, farm, land, mobile)
+    :param radius: Get properties within _ (e.g. 1.0) miles. Only applicable for individual addresses.
+    :param mls_only: If set, fetches only listings with MLS IDs.
+    :param proxy: Proxy to use for scraping
+    :param past_days: Get properties sold or listed (dependent on your listing_type) in the last _ days.
+        - PENDING: Filters by pending_date. Contingent properties without pending_date are included.
+        - SOLD: Filters by sold_date (when property was sold)
+        - FOR_SALE/FOR_RENT: Filters by list_date (when property was listed)
+    :param date_from, date_to: Get properties sold or listed (dependent on your listing_type) between these dates.
+        Accepts multiple formats for flexible precision:
+        - Date strings: "2025-01-20" (day-level precision)
+        - Datetime strings: "2025-01-20T14:30:00" (hour-level precision)
+        - date objects: date(2025, 1, 20) (day-level precision)
+        - datetime objects: datetime(2025, 1, 20, 14, 30) (hour-level precision)
+        The precision is automatically detected based on the input format.
+        Timezone handling: Naive datetimes are treated as local time and automatically converted to UTC.
+        Timezone-aware datetimes are converted to UTC. For best results, use timezone-aware datetimes.
+    :param foreclosure: If set, fetches only foreclosure listings.
+    :param extra_property_data: Increases requests by O(n). If set, this fetches additional property data (e.g. agent, broker, property evaluations etc.)
+    :param exclude_pending: If true, this excludes pending or contingent properties from the results, unless listing type is pending.
+    :param limit: Limit the number of results returned. Maximum is 10,000.
+    :param offset: Starting position for pagination within the 10k limit (offset + limit cannot exceed 10,000). Use with limit to fetch results in chunks (e.g., offset=200, limit=200 fetches results 200-399). Should be a multiple of 200 (page size) for optimal performance. Default is 0. Note: Cannot be used to bypass the 10k API limit - use date ranges (date_from/date_to) to narrow searches and fetch more data.
+
+    New parameters:
+    :param past_hours: Get properties in the last _ hours (requires client-side filtering). Accepts int or timedelta.
+    :param updated_since: Filter by last_update_date (when property was last updated). Accepts datetime object or ISO 8601 string (client-side filtering).
+        Timezone handling: Naive datetimes (like datetime.now()) are treated as local time and automatically converted to UTC.
+        Timezone-aware datetimes are converted to UTC. Examples:
+        - datetime.now() - uses your local timezone
+        - datetime.now(timezone.utc) - uses UTC explicitly
+    :param updated_in_past_hours: Filter by properties updated in the last _ hours. Accepts int or timedelta (client-side filtering)
+    :param beds_min, beds_max: Filter by number of bedrooms
+    :param baths_min, baths_max: Filter by number of bathrooms
+    :param sqft_min, sqft_max: Filter by square footage
+    :param price_min, price_max: Filter by listing price
+    :param lot_sqft_min, lot_sqft_max: Filter by lot size
+    :param year_built_min, year_built_max: Filter by year built
+    :param sort_by: Sort results by field (list_date, sold_date, list_price, sqft, beds, baths, last_update_date)
+    :param sort_direction: Sort direction (asc, desc)
+
+    Note: past_days and past_hours also accept timedelta objects for more Pythonic usage.
