Property tax appeals succeed 30–60% of the time and save an average of $500–$3,000/year when successful. Ownwell and similar services charge nothing upfront and take 25–30% of first-year savings — a no-risk option. To DIY: find 3–5 comparable homes that sold for less than your assessed value, document any condition issues (needed repairs, environmental problems), and file your appeal before the deadline (typically 30–90 days after assessment notice). Most appeals are decided through an informal hearing — dress professionally and present your comparable sales data clearly.
Property Tax Appeal costs are driven primarily by complexity and whether the matter is contested. Simple, uncontested matters with clear documentation can often be handled at flat-fee rates. Once disputes arise, costs shift to hourly billing and become much harder to predict.
Geography matters more than most people realize. Attorney rates in New York or San Francisco can be 2–3 times higher than in smaller markets for the same type of work. If your matter does not require a local attorney, hiring outside a major metro can save substantially without sacrificing quality.
