The MandMarblestone Group

The MandMarblestone Group has built a reputation as Philadelphia's premier property tax consulting firm, helping property owners navigate the complex world of assessment appeals and tax reduction strategies. Our team combines deep knowledge of Philadelphia's unique tax assessment system with proven advocacy skills that deliver real results for clients. We understand that property taxes represent one of your largest ongoing expenses, whether you own a home in Center City or manage commercial real estate throughout the metropolitan area. Our consultants have successfully challenged thousands of assessments, securing millions in tax savings for clients. We don't just file appeals - we develop comprehensive tax reduction strategies tailored to each property's specific circumstances and market position.

Our core service involves comprehensive property tax appeals for both residential and commercial properties throughout Philadelphia and surrounding counties. We begin with detailed market analysis, examining recent sales data, property conditions, and assessment methodologies to identify overvaluation issues. For residential clients, we handle appeals for single-family homes, condominiums, and multi-unit buildings. Our commercial expertise covers office buildings, retail properties, industrial facilities, mixed-use developments, and special-purpose properties requiring unique valuation approaches. We provide ongoing assessment monitoring services, tracking your property's valuation changes and alerting you to potential appeal opportunities. Our valuation analysis services include income and expense reviews for commercial properties, highest and best use studies, and market condition assessments. Additionally, we offer tax reduction consulting for property acquisition and development projects, helping clients understand potential tax implications and planning strategies. Our team also assists with tax abatement applications and appeals of denied abatement requests.

We start with a comprehensive property analysis, examining your assessment history, property characteristics, and local market conditions. During our initial consultation, we'll determine whether an appeal is likely to succeed and provide cost-benefit analysis. If we proceed, our team gathers extensive market data, photographs, and documentation to build your case. We prepare all necessary appeal paperwork and evidence packages, ensuring compliance with strict filing deadlines and procedural requirements. We represent you throughout the entire process, from initial filings through formal hearings. Our team handles all communications with the Board of Revision of Taxes and presents your case professionally. We keep you updated on progress and next steps throughout the 8-18 month process typical for Philadelphia appeals.

We primarily serve Philadelphia County, with extensive experience across all neighborhoods from Old City to West Philadelphia. Our coverage extends to adjacent counties including Montgomery, Delaware, Chester, and Bucks counties where we handle suburban residential and commercial properties. Our Philadelphia focus gives us unique insight into local assessment practices, Board of Revision of Taxes procedures, and neighborhood-specific market trends. We maintain current knowledge of development patterns, zoning changes, and economic factors affecting property values throughout the region.
