Situate the unit within its building

Floor, layout, inclusions, parking and common areas set units apart.

Present this information clearly and confirm it using the available documents.

Prepare the fees and documents

Gather the fees, rules and available information on building maintenance or work.

Required documents vary by transaction; ask the relevant professionals for the list.

Choose relevant comparables
