Yes, you can submit a formal counteroffer along with supporting documents directly to the buyer or their agent via email. You can refer to this article for step-by-step guidance on submitting a counteroffer from your Houzeo dashboard:
👉 How to Submit a Formal Counteroffer. If you received the initial offer through Houzeo’s platform, you can easily counter the offer online, and the buyer or their agent will receive the counteroffer by email.
