When adding a new property, you'll select the type of property and then select "Yes" to the question, "Will you have room rentals?" then click Next. This will prompt you to create a listing for your room rental(s). If you have more than one room rental, you can add additional rooms and create listings for each.

You'll be able to enter the Room Name, Target Rent, and Deposit. If you have more than one room rental, click Add Another Room or Duplicate (if Duplicated, you can edit the Room Name and Target Rent); once you've added the room(s), click Save.

Upon clicking Save, you can Set Up My Listing (to market your rental) or click Skip For Now.
