Season 3, Episode 8: From the ValuVault – Why Tax Assessments ≠ Market Value
Tax assessments are revenue tools, not price gauges
- Purpose – Counties set assessed value to calculate annual taxes, nothing more.
- Lag time – Many jurisdictions update on a 1- to 3-year cycle, so values trail fast-moving markets.
- Broad-brush formula – Mass-appraisal models ignore renovation quality, curb appeal, view premiums, etc.
Real-world gap
- 2025 sale prices are up ≈ 3.8 % YoY. Assessments in several metros trail by 10-20 %.
- Example: Chicago bungalow
- Assessed value → $300 K (2023 roll)
- Current comp-supported value → ≈ $360 K
- Result: great for your tax bill… terrible anchor for list-or-offer strategy.
What buyers & mortgage pros should do instead
- Pull six-month comps from MLS / Redfin / Zillow before you write the contract.
- Order a BPO or full appraisal when upgrades (kitchens, baths, ADUs) change the picture.
- Coach borrowers—lenders use appraisal value, never the county card, when setting LTV.
