*For the purposes of this platform, we refer to counteroffers made by buyer agents as amended offers, because you are amending your offer.

When logged into your account, click on the Buyers tab and you will see a list of all offers you have submitted through the platform. Click on the offer you want to amend > click on the "Actions" dropdown menu on the right side of the offer details page > choose amend offer. 

From here you will be able to edit the terms of your previous offer or the sellers counteroffer (step 1) and then add a message and attach any new documentation supporting your new offer (step 2).
