There are many options for doing an address search in FlexMLS. If you know the full address, you may start typing it into the Quick Launch Bar at the top of the page. You may also use the address search options found within the Menu. Lastly, if you are using the Quick Search template, you may enter the address in the search bar at the top of the template.
Keep it simple by putting a street # and name or just the name, then click enter twice. If you need to adjust the status, town, etc. be sure to click the Exclusively Of option to change it to Of, this will allow you to narrow down the criteria.
