报告摘要:The Internet is having a profound impact on how information flows and how transactions are conducted in the business world; the real estate market is no exception. Using data collected from the most dominant online real estate platform, Zillow.com, we study how online property information affects offline sale prices. Our results reveal that property information on Zillow has a larger influence on the sale price of uncommon properties. Specifically, we find that the length of the property description and the number of photos on Zillow have a significant and positive impact on the price of uncommon houses, while their impact on common houses is not significant. Furthermore, we find that Zestimate, the property value assessment provided by Zillow, influences the sale price of both types of properties; but the accuracy of Zestimate, which varies across areas, does not have a significant impact on property price. Finally, our results indicate that sellers and real estate professionals are willing to provide more property information when the property value is higher, when the property is less comparable to surrounding ones, or when the seller’s asking price is significantly higher than the estimated property value. These findings shed light on how online property information are used by home buyers and sellers for different types of properties, and can help real estate professionals and online real estate platforms better utilize the Internet and improve the efficiency of the real estate market.
