Homeowners
An independent, well-supported value to present at your Board of Assessment Appeals hearing, with the findings explained in plain language.
Independent residential valuation
We develop an independent opinion of your home’s value as of the town’s valuation date, supported by sales of truly comparable properties and a careful analysis of your home’s characteristics. We then compare how similar homes are assessed, providing a second line of evidence for the Board of Assessment Appeals.

Who we help
Homeowners can engage Appraisal Source directly. We also work with attorneys preparing Board hearings or Superior Court tax appeals.

Appraisals with the appropriate effective date for Board hearings and Superior Court appeals, with experienced expert testimony when retained.
How a revaluation works
In a revaluation, the town values thousands of properties at once. It relies on property records, market data, valuation schedules and computer-assisted models to set values across the municipality. That is mass appraisal: a method designed to value an entire town, rather than develop a detailed appraisal of one home.
If the property card is wrong—or your home has condition, updates or site features the broad model does not capture—the result may deserve a closer look. Our analysis focuses on your property: we verify its details, compare it with truly comparable sales, and then examine how similar homes are assessed.
A more complete appeal analysis
We first develop an independent opinion of your home’s value using truly comparable sales as of the town’s valuation date. Then we examine the assessments of similar homes. Together, these findings give the Board of Assessment Appeals two ways to evaluate the town’s assessment.
We develop an independent opinion of value as of October 1 of the revaluation year—not today. We compare your home with sales of truly comparable properties around that date, accounting for differences in size, condition, updates, lot and location.
We then look beyond the value conclusion. We compare how similar homes are assessed in relation to their market values. If those homes carry lower assessments relative to value, the findings provide another basis for asking the Board of Assessment Appeals to review yours.
The appraisal remains independent. It documents what the evidence supports; it does not promise a reduction.
First, get the record right
We compare the town’s property card with the property information, item by item. Errors in the card can affect both the value and the assessment.
The findings come together in a clear, organized report from a Certified Residential Appraiser—evidence the Board can weigh against the town’s value and that may be useful if an appeal goes further.
Connecticut law requires municipalities to assess property at 70% of its present true and actual value. An inaccurate value or inconsistent treatment of comparable homes deserves a closer look. Connecticut General Statutes § 12-62a
What you can do now
Most towns post it on the assessor’s website. Check the living area, rooms, baths, basement, pool and outbuildings.
Save your assessment notice. The usual written appeal deadline is February 20; confirm the date with your town.
After revaluation, many towns offer a chance to correct errors with the assessor or revaluation company.
Keep photos of needed repairs, contractor estimates, removal records and your closing statement if you bought near the valuation date.
Get the Board of Assessment Appeals application from your town and submit it by the applicable deadline.
Give us enough time to research, analyze and complete the report before your hearing.
Researching comparable sales, comparing assessments and preparing a well-supported report takes time. Contact us when you receive your notice or hearing date so there is time to complete the appraisal before the Board hearing.
The appeal window is short
The usual written appeal deadline is February 20. It becomes March 20 when the assessor or board of assessors receives a statutory extension. Confirm your town’s deadline and filing instructions directly with the assessor.
* March 20 if a statutory assessor extension applies. If the Board does not change your assessment, a further appeal to Connecticut Superior Court may be possible; speak with an attorney promptly about the deadline.
2026 revaluations
These towns in our service area appear on the state’s October 1, 2026 revaluation schedule. Confirm the schedule and notice date with your town assessor.
Based on the Connecticut Office of Policy and Management schedule. Towns may postpone a revaluation. You can appeal an assessment even when your town is not revaluing this year.
