If you've looked into property tax appeal services, you've probably seen two pricing models: a flat fee, or a commission based on how much you save. Both are only collected if you win — but they have very different tradeoffs.
How commission-based services work
Most traditional property tax appeal agents charge 25–35% of your first-year tax savings, only collected if the appeal succeeds. The pitch is that you pay nothing unless they win. That sounds appealing — but the math often tells a different story.
The hidden incentive problem with commission pricing
Commission-based services are financially rewarded for overstating your potential savings. A larger promised reduction gets you to sign — even if the numbers are inflated. When the case goes to the King County Board of Equalization and the evidence does not hold up, the appeal fails and you walk away with nothing.
Only 25% of cases that reach a hearing result in a reduction — and cases built on optimistic estimates rather than solid comparable sales data are the ones most at risk of ending up in that 75%.
How flat fee pricing aligns incentives differently
With a flat fee, the service has no incentive to oversell your savings. The fee is the same whether your reduction is $500 or $3,000. That means the recommendation you get is based on whether the case is winnable and worth filing — not on whether the projected savings are big enough to justify a commission.
At Appealo, if we don't think your appeal has strong evidence behind it, we tell you not to file. That's only possible because we're not paid a percentage of your savings.
What this actually costs you
To see the difference, look at what happens to your money under a typical 25–35% traditional commission (we'll use the 30% midpoint for these examples) versus Appealo's flat $79 fee:
- On a $1,000 Tax Reduction: A traditional firm takes $300. With Appealo, you pay just the $79 flat fee, leaving an extra $221 in your pocket.
- On a $500 Tax Reduction: A traditional firm takes $150. With Appealo, you pay just the $79 flat fee, leaving an extra $71 in your pocket.
- On a $300 Tax Reduction: A traditional firm takes $90. With Appealo, you pay just the $79 flat fee, leaving an extra $11 in your pocket.
Why Appealo handles every case with maximum effort
Traditional commission firms push residential accounts to the bottom of the pile because they are trying to manage two completely different property types during the exact same high-pressure filing season.
- The Commercial Angle (Forensic Accounting): Commercial properties like office buildings or retail strip malls are valued based on revenue. Appealing them requires intensive, manual forensic accounting — dissecting intricate income statements, vacancy factors, and tenant lease structures for every unique property.
- The Residential Angle (Statistical Precision): Single-family homes and townhouses require a completely different discipline. Winning a residential appeal isn't about looking at business revenue; it's about proving a flaw in the county's mass-appraisal statistics. It requires a deep, hyper-localized dive into comparable market data, isolating property variables, and proving valuation disparities.
- The Calendar Collision: Both commercial and residential appeals share the exact same short appeal window each year. Because traditional agents are working on commission, they face a massive triage problem when the clock is ticking. They naturally prioritize complex commercial cases that generate massive corporate payouts, leaving residential files rushed or completely ignored.
Built differently for King County homeowners
Appealo completely removes this conflict of interest. Because we focus 100% on residential properties and accept zero commercial clients, your home never has to compete with a skyscraper for an analyst's attention.
Our system can process thousands of King County public data points — official parcel records, recent sales, and neighborhood boundaries — to build a precise comparable sales package for your case. That means a $300 case gets the exact same data precision as a $3,000 case — all for a flat $79.
What Appealo charges
Appealo doesn't charge anything to file. The flat $79 fee is only collected if your assessed value is reduced — whether through a Board ruling or an assessor settlement. No commission. No percentage of savings.
