If you want to reach a property owner at more than one address, you can add multiple owner addresses to a deal.
If you want to remove one of the addresses later, you can!
Simply open a Deal and scroll down to the "Mailing Addresses" section.
Then click the address you want to delete.
Then click Remove Address.
NOTE: If you don't see a delete option, that means the address came from an enhanced search. It is not possible to delete results from an enhanced search.
Make sure the address is not added to your mail queue or you also won't see the Remove Address option.
