Comparable Sales Data Worksheet

What Are Comparable Sales?

Comparable sales are those properties that have sold on the open market and that best match the characteristics of your property. The chart contains explanations for each item. Not all of the characteristics need to be filled out.

Some counties have online databases that can be accessed to collect this information.

Remember that, under the rules, you must submit any new evidence (like the chart) to us, the Board of Tax Appeals, at least 10 business days prior to the date of your scheduled hearing AND you must also provide a copy of that evidence to the other party: the county assessor. See WAC 456-10-505.
