Property tax appeal · Philadelphia
Name a ZIP code. We come back with the commercial parcels worth appealing.
Fifteen minutes, live, on a territory you choose. A ranked list of over-assessed commercial parcels comes back with dollar figures inside a minute, the comparable sales behind the top one, and the owner letter it generated.
If the numbers do not survive your eye, that is a useful fifteen minutes for both of us and we will not write again.
$750 per month, per territory — provisional. Philadelphia only. Not software you log into.
What arrives, every month
A deliverable we produce and send. Three things, for the territory you name.
The ranked list
Every commercial parcel in your territory we can form a defensible market-value opinion on, sorted by the annual tax a successful appeal could plausibly recover. Widest gaps at the top.
The estimated appealable value
A dollar figure on each parcel, with the comparable sales that produced it, so you can check the reasoning before you spend an hour on the property.
The owner letter, already written
A two-page outreach document generated for each qualifying parcel, addressed to the owner on the roll. The part that turns a screened parcel into a signed engagement letter.
There is no login and no dashboard, because there is no login and no dashboard to give you. We run it, and the output lands in your inbox. That is the whole product.
The arithmetic
Subtraction, then one multiplication
Philadelphia assesses at 100% of market value, so the assessed number is the city’s market-value opinion. Where your opinion is lower, the difference is taxable value that should not be there. There is no common-level-ratio step to argue about.
A mid-sized commercial parcel
| Annual tax on the over-assessment, identified by the tool | about $45,000 |
|---|---|
| Philadelphia’s published rate — 0.6159% City plus 0.7839% School District | 1.3998% |
| Which implies a gap between assessed and market value of roughly | $3,200,000 |
| Comparable sales the estimate rested on | 10 |
A parcel the tool actually flagged, not an illustration. The annual figure is what it identified; the gap is that figure divided by the City’s published rate. Over-assessment identified — not tax recovered.
Payback, against your own fee
About $11,000 to $15,700
the contingency fee on an appeal like that if it succeeded in full, at the published 25–35% of first-year savings. Whether any of it is recovered depends on the appeal
$4,000
the deliberately conservative per-appeal fee the tool assumes in its own model
$9,000
a territory for a year, at $750 a month
On a parcel that size, one won appeal at contingency would cover the year; on the $4,000 assumption it takes 2.25 of them. Smaller parcels take more. These are arithmetic applied to published industry ranges, not a claim about anyone’s earnings, and not a forecast of yours.
What it has actually done
Verified on real Philadelphia parcels
We have not run a delivery engagement in property tax appeals, and we will not pretend otherwise. What we have is software that runs, and the figures from running it.
- 77,268
- commercial parcels ingested in about 55 seconds
- 21,921
- core non-residential parcels, carrying roughly $82.5B in market value
- $133,000/yr
- appealable over-assessment identified on a single parcel
- $45,000/yr
- identified on another, from 10 comparables
Identified, not saved. Those are amounts of appealable over-assessment the tool computed on specific parcels. Whether any of it is recovered depends on the appeal, and the appeal is yours. Nothing on this page is aggregated into a success rate or a total, because we have not measured one.
Before you book
Three things you should hear from us first
Each of these would come out on the call anyway. Hearing them now is cheaper for both of us.
It is Philadelphia only
The first-Monday-in-October deadline, the 100% assessment ratio and the nightly public data are all specific to Philadelphia. Suburban Pennsylvania needs a common-level-ratio step this does not do, and New Jersey is a different calendar and a different body. If Philadelphia is a fifth of your book, tell us on the call and we will tell you it is not worth $750 a month yet.
It is not software you log into
No login, no dashboard, no portal, no self-serve access. It is a list and a set of letters that we produce and send you every month. If you ask on the call, the answer will be the same one.
It would not survive a BRT hearing on its own
The Board wants two years of operating expenses, photographs, a property plan, and for multi-tenant and office property, leases and rent rolls. You produce those. This tells you which twenty parcels are worth producing them for.
The third one is the important one. This is a screening deliverable — it decides which appeals are worth your time, and then you do the work that wins them.
The questions you are about to ask
Answered before the call, not on it
“The assessment data is free. Why would I pay for it?”
It is free, it is nightly, and we would say so first. You are not buying data. You are buying a market-value opinion on every commercial parcel in the city, ranked by recoverable dollars, with the owner letter written. The roll tells you what the city thinks each property is worth. It does not tell you which twenty parcels to work on this month.
“A weak appeal can get my client raised.”
Which is exactly why the list is ranked and thresholded rather than exhaustive. It is built to hand back the parcels with the widest defensible gap, not every parcel with any gap. If you want the threshold set conservatively for a first month, we will set it there.
“We already license a national assessment-data product.”
Those supply data and comparable sales, and they are good at it. Ask yours which parcels to appeal this month and see what comes back. That is the job this does, and it is a different job.
“Can I log in and run it myself?”
No. It is a monthly deliverable — the ranked list, the estimated appealable value per parcel, and the generated letters. We would rather give you the flat answer here than have you discover it on the call.
“How do I know the owner is not already represented?”
You do not, and roughly one in five Philadelphia commercial properties files an appeal in a normal year, so the well-advised towers are already on retainer. This is aimed at the other four-fifths — mid-market commercial, industrial, mixed-use and small apartment parcels, where nobody has run the arithmetic because nobody was paid to.
“What is your track record in property tax?”
The software is the track record. There is no delivered client engagement behind it and we are not going to imply one. Pick a ZIP code we have not seen and watch it run.
Price
$750
per month, per territory
Provisional, while this is a small service run by hand rather than a product with a price list. If your book is large enough that one territory does not describe it, say so on the call and we will quote it properly.
Who this is for
Philadelphia-metro appeal practitioners — law firms with a real-estate tax assessment practice, and boutique property-tax consultancies — whose work is commercial rather than residential.
If you own or manage Philadelphia commercial property rather than appealing on behalf of others, the useful conversation is a one-time look at your own parcels. Ask for that one instead.
Fifteen minutes, on a ZIP code you pick.
Nothing to install and nothing to prepare. Bring a parcel you already know the answer on and check ours against it.
