BASAO

In today's fast-moving real estate market, accurately determining property value is critical for buyers, sellers, and investors. However, traditional valuation methods are often time-consuming, inconsistent, and prone to human error.

BASAO is an AI-powered real estate valuation tool developed by SotaTek's expert team to revolutionize property evaluation. By leveraging advanced machine learning algorithms and real-time market data, BASAO delivers fast, reliable, and highly accurate property valuations. This empowers buyers, sellers, and investors to make informed decisions with confidence.

Real estate valuation is essential for buying, selling, and investing, but traditional methods are often slow, costly, and inconsistent. Relying on manual research and subjective comparisons, valuations can take days or weeks, delaying decisions for individuals, businesses, and government agencies.

As real estate markets evolve, the need for faster, data-driven valuation has grown. Inaccurate pricing can cause financial losses, risky investments, and inefficiencies, leading buyers to overpay, sellers to undervalue, and investors to misjudge potential returns. Recognizing these challenges, the SotaTek team developed BASAO to address the pain points faced by different stakeholders in the real estate industry.

• For property owners and buyers, valuation costs can be prohibitively high, ranging from 0.1% to 1% of the total asset value. Additionally, the market is often flooded with inaccurate or misleading pricing information, making it difficult for buyers and sellers to make informed decisions.
• For property appraisers, connecting with individual clients remains a challenge. Many appraisers have access to valuable real estate data but lack the tools to efficiently utilize it, leading to price inflation and market speculation.
• For the government, annual land valuation requires significant resources, placing a strain on public budgets and administrative efforts. The process is labor-intensive and costly, adding to the overall inefficiencies in property valuation.

To ensure speed, accuracy, and efficiency in real estate valuation, BASAO is built with a well-structured tech stack that integrates AI models, a responsive backend, and an intuitive user interface.

Technology stack including: 

• Backend (BE): FastAPI
• Frontend (FE): Next.js
• Database (DB): PostgreSQL, ChromaDB, QGIS, GeoServer
• Artificial Intelligence (AI): Reinforcement Learning, LangChain, PyTorch, LLM
• Data Processing: Pandas, Numpy, Scikit-learn, Matplotlib/Seaborn
