Zillow美国房屋交易数据

Zillow是美国最大的在线房地产信息平台之一，主要向用户提供线上免费房地产查询及估价服务。该平台涵盖了全美范围内的房屋信息，‌包括房屋价值估计（‌如Zestimate）‌、‌历史成交信息、‌租金信息等。‌  Zillow平台为用户提供了免费、便捷的房屋查询服务，登入平台后，用户可自行在网页上缩放卫星地图寻找标的，或利用邮政编码和街道进行搜寻。Zillow通过美国房地中介业者公用的买卖数据库及自行开发的「Zestimate」的计算机系统，根据房屋的历史交易价格提供房地目前的市价推估。这些信息为用户提供更加精准和个性化的房地产信息服务，帮助房地产专业人士和买卖双方更好地了解市场趋势和房屋价值；但与此同时，不动产实际价值的公开与开放也似乎正在冲击着以“信息差”为核心的传统房地中介。

Zillow is one of the largest online real estate information platforms in the United States, mainly providing users with free online real estate inquiry and valuation services. The platform covers housing information across the country, including home value estimates (such as "Zestimate"), historical transaction data, rental information and more. Zillow offers free and convenient home inquiry services. After logging into the platform, users can zoom in and out on satellite maps to locate target properties, or conduct searches using zip codes and street addresses. Leveraging the transaction databases shared by U.S. real estate agencies and its self-developed "Zestimate" computing system, Zillow provides current market value estimates for properties based on their historical transaction prices. This information delivers more precise and personalized real estate information services, helping real estate professionals, buyers and sellers gain a better understanding of market trends and home values; however, the public disclosure and openness of actual real estate values appear to be impacting the traditional real estate brokerage industry which centers on "information asymmetry".
