How this service works

Where does my tax assessment sit among similar properties on the same roll, when is the appeal deadline, and how do I file. No dollar figure required. Reuses the same-roll assessment-uniformity percentile, the state appeal-deadline rule, and the local-or-state filing guide; Locus never creates or endorses a value and never recommends whether to appeal. npx @velinussage/locus-agent-skill add.

Output

Returns the property's assessment uniformity percentile rank among comparable properties on the same tax roll within the specified radius, the state-specific appeal deadline derived from the notice date, and a local-or-state guide on how to file an appeal — without providing or endorsing a dollar valuation or a recommendation to appeal.

Example use cases

Homeowner checking assessment fairness

“I just got my 2024 property tax assessment notice for 88 Maple Street, Austin TX dated 2024-04-01 — where does it rank among comparable properties within 500 meters, and what's my deadline and process to appeal?”

Real estate investor reviewing portfolio property

“Can you pull the assessment position for my rental property at 310 Oak Avenue, Denver CO, notice year 2024, and tell me whether it's in the top or bottom percentile on the same roll and what the Colorado appeal deadline and filing steps look like? Use a 400 meter radius.”

Property tax attorney pre-screening client

“Before I take on this client, check where the 2023 tax assessment for 1450 Lakeview Drive, Chicago IL sits among same-roll comparable properties within 800 meters, and pull the Illinois appeal deadline and how to file so I know if there's a case worth pursuing.”

When to prefer

Use this endpoint when a user wants to understand their property tax assessment's relative position among similar properties on the same roll, needs to know the appeal deadline based on a specific notice date, or wants filing guidance — without requiring a dollar appraisal or a value opinion. Prefer this over generic tax or appraisal APIs when jurisdictional appeal deadlines and same-roll uniformity percentile are the core need.

Side effects

Address not found or unrecognized — returns an error indicating the parcel could not be located
No comparable properties found within the specified radius — may return null percentile or suggest widening radius
Notice date or year out of supported range — validation error returned
Address string too short (under 5 chars) or too long (over 200 chars) — schema validation failure
Radius outside allowed range (100–1200 meters) — schema validation error
State appeal rules unavailable for a given jurisdiction — partial response with available fields only
