You guys are all correct. Our MLS here in San Diego (and I assume all other MLS’s) enables us Realtors to set up automated email searches to send out to leads. We can setup the search anyway we want. Most of us will setup the search to capture new listings and ANY changes in a listing or listing status. Thus any time there is a change in status such as the price then that listing will get captured by the automated search and thus sent out to all of our leads. Even if the price change was not any literal change at all.
So yep it is all a game we play to get our listing more attention.
