Home improvements can boost your home’s appraised value—what it’s worth on the market—while also increasing the appraised value vs assessed value your property taxes. Upgrades like kitchen remodels or additions may raise both values, affecting resale potential and annual tax costs. Understanding appraised value vs. assessed value helps homeowners make informed renovation decisions and avoid tax surprises.
Defining the Terms: Appraised Value vs. Assessed Value
Though they sound similar, appraised value and assessed value serve different purposes and are calculated differently.
Term |
What It Is |
Used For |
| Appraised Value | An estimate of a home’s fair market value by a licensed appraiser. | Mortgage approval, refinancing, home sale. |
| Assessed Value | A value assigned by your local tax authority for property tax purposes. | Annual property tax calculations. |
In short:
- Appraised Value = What your home could sell for in today’s market.
- Assessed Value = The taxable value your city or county uses to calculate your property tax bill.
Why It Matters:
Understanding the distinction helps homeowners avoid the pitfall of over-improving and prepares them for tax changes that come with major upgrades.
How Home Improvements Affect Appraised Value
Your Licensed appraisers determine your home’s appraised value by comparing it to similar properties (or “comps”) recently sold nearby. They consider:
- Location
- Size and layout
- Condition
- Quality of materials
- Upgrades and renovations
Improvements That Often Increase Appraised Value:
- ✅ Modern kitchen remodels
- ✅ Updated bathrooms
- ✅ New flooring or roofing
- ✅ Energy-efficient windows and systems
- ✅ Finished basements or added living space
Example:
Suppose your home was appraised at $350,000. After spending $30,000 on a new kitchen and energy-efficient HVAC:
- The updated home is now appraised at $380,000
- That’s a $30,000 investment for a $30,000 return, or 100% ROI
How Home Improvements Affect Assessed Value
Your assessed value is determined by the local tax assessor and is usually updated annually or biannually. Most jurisdictions use a percentage of your home’s market value (often 70–90%) to set this number.
What Triggers a Higher Assessed Value?
- Major additions (new bedroom, second story)
- Finished basements or attics
- Detached structures (garages, sheds, pools)
- Upgrades requiring permits
Example Calculation:
- Appraised value after renovations: $400,000
- Assessment rate: 85%
- New assessed value = $340,000
- Local property tax rate: 1.25%
- Annual property tax = $4,250
If your home was previously assessed at $300,000, you’re now paying $500 more per year in taxes.
Real-World Examples: Comparing Impacts
Scenario 1: Cosmetic Upgrades (Low Permit Impact)
- Improvements: New paint, light fixtures, hardware
- Appraised Value: Minor increase due to freshness
- Assessed Value: Usually unchanged
Scenario 2: Bathroom Addition (Structural)
- Improvements: Added full bath with permits
- Appraised Value: Increases based on added functionality
- Assessed Value: Likely reassessed upward
Scenario 3: Finished Basement (Unpermitted)
- Appraised Value: May increase slightly
- Assessed Value: Might not change unless discovered by assessor
