Potential buyers will want to know about your community as well as your individual unit.  To be prepared, obtain from your association the schedule for total community repair and maintenance, such as the buildings due to be painted, major landscaping, roof replacements, clubhouse decorating, driveway paving or deck replacement, as well as recent or upcoming special assessments or pending litigation.
 

Locate your public offering statement (also known as a prospectus).  You should have received this document when you purchased your townhouse.  If you can't locate it, you can purchase one from your association.
 

Buyers will appreciate having a copy of the floor plan.  If you have the original community brochure, that would be helpful.
