Why You Need an Independent Appraisal
Defensible Evidence
A USPAP-compliant appraisal carries weight that Zillow estimates, agent opinions, and homeowner arguments do not. It’s the professional standard that assessors and boards are trained to evaluate.
Time-Trended Analysis
Tax appeal appraisals must reflect value as of the county’s base date, not today. Charles E. Volk, SRA and Colin O’Connor prepare appraisals trended to the correct effective date for your assessment cycle — drawing on 24 years of Denver Metro and Boulder County market knowledge.
BOE-Ready Reports
If your initial protest is denied, the next step is the Board of Equalization. Our reports are built to hold up at this level — not just at the assessor’s desk. Have questions about the process? See our frequently asked questions.
SRA Credential
Charles E. Volk holds the SRA (Senior Residential Appraiser) designation from the Appraisal Institute — signaling to assessors and boards that your appraiser meets the highest professional standards in residential valuation.
VolkHaus Appraisals serves homeowners across Denver Metro and Boulder County. If you’re also dealing with an inherited property, learn about our estate and date-of-death appraisal services.
