Frequently Asked Questions

Why retain Duffy & Catlin to challenge your property assessment? +

Duffy & Catlin have over 20 years of experience challenging assessments throughout New York. We have challenged thousands of assessments and achieved millions of dollars in tax savings for our clients. Our firm handles every aspect of your case — from the initial review to formal hearings — so you don’t have to navigate the process alone.

What types of properties have we challenged? +

We have represented owners of a wide variety of property types, including:

Apartments · Assisted Living Facilities · Banks · Condominiums · Gas Stations · Golf Courses · Hotels · Industrial Parks · Manufacturing Facilities · Marinas · Mobile Home Parks · Drug Store Chains · Retail Chains · Office Buildings · Real Estate Developments · Restaurants · Senior Living and Memory Care Facilities · Shopping Centers · Warehouses

Do I have a case? +

We provide a thorough analysis of your case at no charge. If we determine that your property is over-assessed, unequally assessed, or illegally assessed, we will vigorously advocate for a fair resolution. The initial consultation costs you nothing and commits you to nothing.

What will it cost? +

Our legal fee operates on a strict contingency basis, meaning we will never charge you a legal fee unless we successfully reduce your assessment, and only after you’ve received a tax refund or a lower property tax bill. There is zero financial risk in having us evaluate your property.

What is Grievance Day and why does it matter? +

Grievance Day is the statutory deadline to file a formal challenge to your property’s assessed value. For most New York towns, it falls on the fourth Tuesday in May — but cities operate on their own independent schedules, often much earlier. Missing the deadline eliminates your right to challenge for that tax year. Contact us as early as possible so we have the maximum time to build a thorough case.
