Article Summary
According to the online real estate database company Zillow, homes located near a Whole Foods or Trader Joe's location have appreciated in value at double the rate of homes in other areas. From 1997 to 2014, the median U.S. home had appreciated 71 percent, while a median home near a Whole Foods or Trader Joe's appreciated 140 percent and 148 percent, respectively. Although some analysts believe this is due to these retailers often opening stores in high-income neighborhoods, Zillow researchers found that before a Whole Foods or Trader Joe's opened, homes near where the stores would eventually be appreciated at the same pace of comparable homes across the city, but after the stores opened the appreciation rate of homes in close proximity increased at a faster rate.
