Is your $441,000 assessment defensible?

Pull up any parcel and see its assessed value plotted against every comparable sale in the neighbourhood — matched on land character, not just zip code proximity. Know in seconds whether you have a case.

Most property owners who suspect their assessment is too high have no practical way to check. The PVA website shows your assessed value; it doesn’t show you the comparable sales the assessor used, the multi-year trajectory, or whether the methodology matches the actual terrain and use character of your parcel.

Appraisr does all three. The backend is live against the taxr database; the iOS chart UI is the next sprint.

Similar land, not just nearby

Traditional appeal tools find comparable sales by drawing a radius around your parcel and sorting by distance. That produces comps that are geographically close but physically dissimilar — the steeply sloped, unbuildable lot 200 meters away is not a good comp for a flat, developable 2-acre parcel, regardless of proximity.

The structural problem with radius-based comps: for topographically varied parcels, distance-only comps are systematically wrong. A flat, buildable 2-acre lot is more comparable to another flat 2-acre lot half a mile away than to a steep, unbuildable lot next door. The official methodology produces errors that skew in a predictable direction — toward over-assessment of flat land and under-assessment of undevelopable slopes, because slope isn’t in the radius filter.

Appraisr scores each candidate comp by what the parcel actually is — slope, lay of the land, how much of it is flat — alongside acreage and property class. A flat parcel gets compared to other flat parcels at similar acreage. The result is a comp set that reflects what an appraiser doing field work would find, not what a radius query returns.

What Appraisr surfaces per parcel

Assessment timeline

Multi-year assessed value plotted as an interactive timeline. See whether the trajectory is flat, rising, or contains an anomalous jump that signals an error year.

Comparable sales

Recent arms-length transactions for actually-similar parcels — same property class, comparable acreage, similar slope and lay of the land. Plotted against your assessment for direct comparison.

Land profile

Slope, lay of the land, flat acreage. The numbers that drive the comp matching — verifiable against the underlying terrain data.

Assessment context

Property class, assessed acreage, current year value, exemption status. The full legal assessment record on file with the county.

Appeal export

PDF summary of the assessment timeline and comparable sales — formatted for the county board of assessment appeals. The data package you hand to the board.

The default test parcel

Appraisr opens to a verified McCracken parcel as the default test case. Assessment history, comparable sales query, and land profile are all live for any McCracken parcel — type any address to check yours.

The question Appraisr can already answer: is this assessment defensible given the comparable residential sales in the 1.5–3 acre range in McCracken County over the last 24 months? The on-device chart to present that answer is the next build sprint.

What’s not in there yet

iOS chart UI — the current stub uses hardcoded sample data. Don’t use it. The backend is live and returning real data.
Appeal export PDF — the data is there; the document template is next.
Neighborhood-level valuation distribution — individual comps are queryable; aggregate histograms are a later view.
McCracken only in v1 — extends automatically when sister counties come online.
