About the Boulder County Assessor
The listed sales documents are organized around distinct property groups: commercial condominium sales, commercial sales by use, manufactured housing, and vacant property. Several of these titles are explicitly labeled 2021. Together, they show that the sales materials are categorized by property type or use rather than presented as one broadly named sales document.
Other entries are questionnaires, with titles covering agricultural topics, apartments, and income and expenses. These are distinct from the sales materials: the questionnaire titles identify subject areas, while the sales titles identify property categories. Checking the title can help you find the document that matches the topic you are looking for.
