How do I edit/delete a search alert?

From the dropdown menu click on "Manage Alerts."
This will bring you to the "Saved Search Alerts" page, find the alert you would like to update and click the "edit" button on the right hand side of the screen
Edit your "markets" using the location search, you can add as many countries, states, or cities as you would like in this section. (This location search is powered by google, click on the results from the dropdown)
You can also remove a location by clicking the small "x" next

5. After your markets are added, choose your property type, price range, building size, ect.

6. Each time you update this page it will save automatically, once you are finished hit the back button to return to the saved search alerts page.
7. The last step is to choose the frequency in which you would like to receive these email alerts. You can choose from instant (an email is sent the second a listing that matches your criteria is posted), daily, or weekly.
8. There's not a delete button for a search alert but you can disable a search alert by choosing "frequency" and then select "disabled" from the drop down menu.
