If “Estate Agent” exist in the Ruleset, append the following:

A Realtor may auction the rights to sell off a House. As a Daily Action, a Realtor may make a Story Post to Agent a non Agented and not in Auction House, including the name of the House and the amount of Bucks they intend to pay. A Realtor may reply such Story Post with another number of Bucks more than the previous comment or Post. If such Story Post has no new Reply in 12 hours counting from the latest Reply (or the Posting of the Story Post if there is no Comment), the Realtor who made the last Comment(if there is no Comment, the Realtor who made the Story Post) pays the amount specified in their latest Post or Comment and puts their name as the Agent of said House.

Directly after the list of Attributes, in that same rule, append the following:

Each House may be Agented by a Realtor, which default to none.
