Most traditional property tax appeal firms operate on a commission model: they take 25 to 35 percent of your first-year tax savings, collected only if they win. On the surface, this sounds like a risk-free arrangement. In practice, it creates an incentive structure that works against typical homeowners.
The commission math problem
A commercial property assessed at $5 million might generate $5,000 in annual tax savings if successfully appealed. At a 25% commission, that is $1,250 for one case — high margin, worth deep effort. A residential home assessed at $500,000 might generate $500 in annual tax savings. At 25% commission, that is $125.
Both examples assume a 10% over-assessment and a 1% levy rate. The numbers are realistic. The implication is straightforward: firms that handle both commercial and residential work have a strong financial incentive to allocate their best analysts and most preparation time to commercial cases.
What deprioritization looks like in practice
- Residential cases are assigned to junior staff while senior analysts focus on commercial portfolios
- Comparable analysis is less thorough — fewer comps, less scrutiny of quality
- Hearing preparation is minimal — the case is filed but not deeply built
- Communication is slower and less detailed for residential clients
None of this is malicious. It is the predictable result of a business model where different case types generate vastly different revenue. A firm optimized for commercial work is structurally misaligned with what a King County homeowner needs.
The national platform problem
Large national appeal platforms face a different version of the same issue. They operate across dozens of states with different rules, different data sources, and different hearing procedures. King County has specific requirements — NWMLS comparables, area-by-area assessment schedules, BOE hearing procedures — that a generic national workflow is not optimized for.
How a flat fee changes the incentive
A flat fee removes the commission disparity entirely. When the fee is the same regardless of whether the property is a $400,000 townhouse or a $900,000 single-family home, every case gets the same preparation. There is no financial reason to rush a smaller case.
Appealo charges a flat $89 — only if your assessed value is reduced. We work exclusively with King County single-family homes and townhouses. Every case gets the same depth of comparable analysis and the same hearing representation.
