Hello,
To tackle this project, I will begin by carefully selecting reliable data sources, possibly from government websites or real estate marketplaces, ensuring they offer the required historical data. I will then automate the data collection process using web scraping libraries like BeautifulSoup and Selenium, with separate scripts for each state and county. Following data collection, I will perform data cleaning and preprocessing to handle missing values and inconsistencies, converting the data into a standardized format. My analysis will encompass descriptive statistics, geographical visualization using libraries like GeoPandas, and a focus on cash sales trends versus other types. I will present the insights and findings in a well-documented report, including interactive dashboards if necessary, while adhering to data privacy regulations and respecting data source terms of use. Throughout the project, thorough documentation and quality assurance checks will ensure accuracy and reproducibility, with iterative reviews to meet your expectations.
