Is Your Amherst
Property Assessment
Excessive?

Amherst's assessment roll covers Williamsville, Eggertsville, Snyder, Getzville, and East Amherst — one of Western New York's largest and most active suburban markets. Many owners now carry assessments that don't reflect actual market conditions or the specific condition of their property.

An assessment is an opinion, not a final number. Duffy & Catlin PLLC represents commercial, industrial, and residential owners across Amherst and Erie County in challenging assessments that don't hold up — at no upfront cost.

Why Amherst Owners Are Seeing Increases

How Amherst Values Your Property — and Where It Goes Wrong

When Town of Amherst builds its assessment roll, properties are valued in bulk using broad market models. Those models lean on neighborhood-wide trends — not your building's condition, your block, your actual rent roll, or the most relevant comparable sales.

Amherst is anchored by UB's North Campus, the Northtown commercial corridor, and a deep base of office, medical, and retail space. As suburban demand shifts, mass-model assessments can lag or overshoot what a specific property is truly worth. New York law lets you challenge an excessive assessment — but towns hear grievances only on Grievance Day, the 4th Tuesday in May.

  • Income-producing properties have distinct valuation standards the assessor is required to apply
  • Vacancy, below-market leases, and deferred maintenance are all recognized grounds for challenge
  • Older and industrial properties often carry functional obsolescence that mass models overlook
  • You are not required to accept the town's opinion of value as final

Who We Represent in Amherst

Commercial, Industrial & Residential Challenges Across the Town

Commercial and industrial properties are especially vulnerable to over-assessment in a mass revaluation. The income, cost, and sales-comparison approaches each require proper application — and a mass model doesn't always get Amherst right.

🏢

Commercial & Office

Northtown retail, office and medical parks, and mixed-use buildings along Maple, Sheridan, and Transit are frequently assessed without proper regard for real vacancy, lease terms, or market income. We apply the correct methodology to challenge inflated values.

Northtown retail Office parks Medical office Mixed-use
🏭

Industrial & Warehouse

Flex space, warehouses, and R&D/lab buildings near the UB corridor carry functional obsolescence and thin comparable sales that mass appraisals routinely miss.

Flex space Warehouses R&D / lab Light industrial
🏠

Residential & Multi-Family

Homes and condos in Williamsville, Snyder, Eggertsville, and East Amherst all benefit from review. Even modest increases compound into real tax liability over an assessment cycle.

Hidden Tax Increases

Even a Flat Assessment Can Cost You More

New York calculates an equalization rate for every municipality — the ratio of assessed value to full market value. When Amherst and Erie County market prices rise faster than assessments are updated, that rate falls, and the State treats your property as worth more for purposes of county tax apportionment.

The result is a larger share of the Erie County levy landing on your bill — with no change to the assessment roll and no formal notice. If your assessment was already excessive, the compounding effect is even greater. A timely challenge corrects both problems at once.

How a Amherst Challenge Works

Step 1

Free Case Review

Send us your assessment notice. We evaluate whether your Amherst property has been over-assessed and advise you honestly on the strength of a challenge — at no cost and no obligation.

Act Early
Step 2

Informal Review

Amherst's assessor often allows a brief period to engage before the formal deadline. Early contact gives us the most time to build a complete, well-supported case.

Hard Deadline
Step 3

Common Questions

Amherst Property Owners Ask

When is the deadline to challenge my Amherst assessment? +
Town grievances in New York are heard on Grievance Day — the 4th Tuesday in May — after the tentative assessment roll is published, typically around May 1. The Town of Amherst follows this schedule. The window is brief and unforgiving once it passes, so the safest step is to contact us as soon as the tentative roll is out (or earlier) so we can review your assessment and file in time.
If my assessment went up, does that mean my taxes are going up? +
A higher assessed value doesn't automatically raise your bill — it depends on your assessment relative to other Amherst properties and the applicable tax rates. But a significantly elevated value can translate into a real increase in town, county, and school taxes, especially for commercial and industrial property. We can review your specific notice and explain what it means for you.
Do you handle properties outside Town of Amherst? +
Yes. We represent owners throughout Erie County — Tonawanda, Clarence, Cheektowaga and beyond — and across all of New York State. Town properties follow the standard Grievance Day schedule, while cities use their own charter deadlines. We track the correct one for your municipality.
What does it cost to have Duffy & Catlin PLLC challenge my assessment? +
Nothing upfront. We work on a contingency basis — we only collect a fee if we achieve a reduction in your assessment. The initial consultation and case review are always free. There is no financial risk in having us evaluate your Amherst property.
What makes commercial challenges different from residential ones? +
Commercial valuation is considerably more involved. Income-producing properties are typically valued using an income-capitalization approach that accounts for vacancy, actual rents, operating expenses, and market cap rates. Mass reassessments frequently fail to apply these factors correctly, which is why commercial challenges often have strong evidentiary grounds.
What if my case isn't strong enough to challenge? +
We'll tell you that upfront — at no cost. We only pursue challenges where the evidence supports a meritorious case. Our credibility with the Amherst assessor and the Board of Assessment Review depends on bringing well-grounded, properly documented appeals.
How long does the process take? +
The informal review and Board of Assessment Review process typically runs through spring and early summer. Cases that proceed to SCAR or Article 7 court proceedings may take additional months. Throughout, our attorneys handle all communications and appearances on your behalf.
