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 edit 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 edit.
Then edit the address and click save.
NOTE: If you don't see a edit option, that means the address came from an enhanced search. It is not possible to edit results from an enhanced search. As an alternative to editing, you can always manually add new addresses to a deal.
