Decide whether the format suits you
An open house can be one tool among others; its usefulness depends on the property, the timing and the applicable rules.
Discuss the advantages, limits and safety measures with the person assisting you.
Prepare the spaces and information
Tidy the rooms, secure personal belongings and prepare verified information about the property.
Plan who will welcome visitors and how questions and contact details will be collected.
Follow up after the visit
Organize the feedback and requests for private visits after the event.
Attendance at an open house is not an offer; assess interest using all the feedback and data available.
