The best way to find a home that was once listed on the MLS is to use a search engine and the old MLS number or the home's address. The MLS number or address, even if it only includes the house number and street number, should turn up results from various real estate websites that promoted the home when it was listed. These websites range from brokerages to real estate databases, such as Redfin, Movato.com, Estately and Homes.com. Such databases pull and store listing information directly from the MLS in the area where the home is located.
