Free Synthetic Real Estate Listings — 100M Rows A free, fully synthetic dataset of 100,000,000 US real estate listings, generated for developers and builders working on price-prediction models, real-estate analytics, search/filter UIs, and BI pipelines — realistic property data without touching any real listing, address, or owner. Every value in this dataset is artificially generated. No real properties, no scraped listings, no real addresses or PII. What makes it useful:… See the full description on the dataset page: https://huggingface.co/datasets/ziadatalabs/FreeRealEstate100M.
🏘️ 100 triệu mẫu bất động sản giả lập — không chạm tới dữ liệu thật
Dữ liệu giả lập hoàn toàn, giá nhà tính thật từ diện tích và vị trí thành phố.
FreeRealEstate100M là bộ dữ liệu bất động sản giả lập 100.000.000 dòng của Zia Data Labs, phát hành miễn phí dưới giấy phép CC BY-NC 4.0. Không chứa bất kỳ bất động sản, địa chỉ hay thông tin cá nhân thực nào, an toàn cho phát triển mô hình và pipeline dữ liệu.
✨ Điểm nổi bật
- Giá nhà tính thật: dựa trên diện tích × giá/m² theo thành phố, điều chỉnh theo loại nhà, tình trạng, năm xây.
- 100 triệu dòng: một file Parquet nén Snappy khoảng 2GB, tải nhanh bằng pandas, polars, DuckDB.
- 17 cột đầy đủ: từ listing_id, city, zip_code đến listing_price, price_per_sqft, days_on_market.
- 40 thành phố lớn: phản ánh chênh lệch giá thực tế giữa các vùng (miền bờ Tây cao hơn miền nội địa).
- Hỗ trợ truy vấn nhanh: dùng DuckDB để phân tích mà không cần tải toàn bộ vào bộ nhớ.
- Giấy phép rõ ràng: CC BY-NC 4.0, dùng cho nghiên cứu, giáo dục, phi thương mại.
- Không rủi ro PII: toàn bộ dữ liệu đã được sinh ngẫu nhiên, không rò rỉ thông tin cá nhân.
💡 Vì sao đáng chú ý
Khác với các bộ dữ liệu bất động sản giả lập khác, FreeRealEstate100M không gán nhãn giá ngẫu nhiên — mỗi giá đều là kết quả tính toán logic từ các đặc trưng bất động sản. Điều này giúp mô hình học được mối quan hệ thực sự: diện tích lớn, vị trí đẹp, tình trạng tốt → giá cao hơn. Phù hợp cho huấn luyện mô hình dự đoán giá, xây dựng giao diện tìm kiếm lọc, hoặc kiểm thử pipeline phân tích dữ liệu lớn.
