Current Comparable Sales Lists

Below are the 2009 Comparable Sales reports by type of property. To research commercial sales information, click on the “commercial” link below.  Once you open the appropriate report, you can save and manipulate the information as needed. 

The information is sorted by “superneighborhood” (economic neighborhood) and then by neighborhood (subdivision).  The listed sales are qualified valid sales from July 1, 2006 through June 30, 2008. 

If you do not find sales within your specific neighborhood, contact the Eagle County Assessor’s Office at 970-328-8640 for assistance. 

EFFECTIVE SQUARE FOOTAGE

The mass appraisal computer system is designed to make specific mathematical calculations to the non-living area square footages, rather than make separate valuation calculations of these subareas.  This method provides more uniform comparison of properties for valuation purposes, since all properties are adjusted for their individual characteristics uniformly, which leads to the equitable distribution of value among the parcels throughout Eagle County.

The determination of building size is initially done from building plans. The dimensions of each building are then confirmed by physical review. The first step in this process is the calculation of the main living area and sub-areas, i.e., garages, porches, decks and/or outbuildings.

The actual square footage for each area is adjusted by various weights to derive a value. A simple example of this adjustment would be a full unfinished basement in a 1000 square foot home. Market data indicates that an unfinished basement will add approximately 20% to the value of a typical residential property.  The property card would read as follows:

The sum of the effective area is then multiplied by the indicated value per square foot to establish final building value, i.e., 1200.21 X $165.24 = $198,320. (rounded)

Note: The effective square footage will be printed on all of the Notice of Value forms and viewed this way.

TIME ADJUSTED SALE PRICE

By definition a time adjustment is, "An adjustment for the difference (if any) between market conditions at the date of sale of a comparable property and the date of appraisal (June 30, 2008) which results in a time adjusted sale price (TASP)."

A TASP is defined as, "The price for which a property sold at some given time, adjusted for the effects of inflation or deflation between the date of sale and the date of appraisal. Three methods of time trend analysis are used by Eagle County:  sales ratio technique, sales price per unit of measure (i.e. sales price per square foot), and model/regression derived.

The three approaches are reviewed for validity and feasibility, and one is chosen.  In MOST cases, the model/regression derived time trend was used for the 2009 reappraisal.  This method places time as a variable in the model and adjustments are calculated through the model just like adjustments for quality.

All available qualified sales were analyzed within various economic regions, (Vail, Avon, Edwards, Eagle, etc), and by type, (vacant or improved, residential or commercial).  Each individual sale was then adjusted to the appraisal date of June 30, 2008.

For the 2009 reappraisal, 2 years of data spanning from July 1, 2006 was examined.  In many cases a spline trend was applied (i.e. we accounted for differing appreciation rates over time).  A time adjustment was applied to the following areas for the 2009 reappraisal:
