Gunderson Dettmer

Gunderson Dettmer brings decades of tax expertise to Ann Arbor property owners facing assessment challenges. Our team specializes in property tax appeals and valuation disputes, helping clients reduce their tax burden through strategic analysis and proven advocacy methods. We understand that property taxes represent a significant ongoing expense for both residential and commercial property owners. That's why we focus on thorough assessment reviews, identifying opportunities for legitimate reductions while maintaining positive relationships with local tax authorities. Our approach combines technical expertise with practical knowledge of Michigan property tax law.

Our comprehensive property tax services include assessment appeals for both residential and commercial properties, covering everything from single-family homes to large industrial complexes. We conduct detailed property valuations using comparable sales data, income analysis, and cost approach methods to build compelling cases for tax reduction. Specialized commercial services include assessment challenges for office buildings, retail centers, manufacturing facilities, and multi-family properties. We also handle complex valuation issues such as functional obsolescence, economic obsolescence, and special use properties. For residential clients, we provide homestead exemption assistance, assessment timeline management, and representation at Board of Review hearings. Additional services include tax consulting for property purchases, development projects, and portfolio management strategies.

The process begins with a comprehensive property assessment review where we analyze your current tax situation and identify potential savings opportunities. We examine recent sales data, property conditions, and assessment methodologies used by local assessors. Once we identify viable grounds for appeal, we prepare detailed documentation including property valuations, comparable sales analysis, and supporting evidence. We then file necessary appeals within required deadlines and represent you through all hearing procedures. Throughout the process, we keep you informed of progress and strategy adjustments, ensuring you understand each step and decision point.

We serve property owners throughout Washtenaw County and southeastern Michigan, with particular expertise in Ann Arbor, Ypsilanti, and surrounding townships. Our familiarity with local assessment practices, market conditions, and municipal procedures allows us to provide targeted strategies for each jurisdiction. We also handle cases in adjacent counties including Oakland, Wayne, and Livingston, adapting our approach to local regulations and assessment practices.
