Tax Assessment Valuation Information in Boulder County

I attended a presentation by Cynthia Braddock, the Boulder County Assessor this week on the recent property valuations that were sent out. Those valuations were conducted using a computer program mass appraisal method. They sent out a postcard instead of the full valuation to save on postage costs, but by logging into the website on the postcard and putting in your account and pin number (also on postcard) you can access your full valuation and get an estimate on what your taxes will be (there is a tax calculator on the site). Check out the live video on my FaceBook page for what the algorithm factors in when calculating the value, along with how to build an effective appeal. When you appeal, you get a human to actually look at the comps in the area. Here are some tips on building an effective appeal:

  1. sign the appeal form
  2. be sure it is on time - either delivered on or postmarked June 1, 2017
  3. the reason can be as simple as “the value is too high”
  4. if you do provide comps, it is key to only use comps between July 1, 2014-June 30, 2016
  5. if you have estimates from contractors, you can provide them
  6. bring photos of the interior supporting your recommended price
  7. provide an appraisal from a purchase or refinance

If you provide any comps or appraisals, they will adjust the value using their time trending so that all value snapshots are of the property on June 30, 2016 (so if you provide comps from 2015, they will increase the value to represent what the trend was in mid 2016). On average, 50% of people who appeal their valuations succeed in getting it changed!
