Property Tax Appeal

Q: How do I know the Property Tax Appeal output is good?

The skill verifies itself against its own quality checks: Tests the assessment against real comparables/condition; Checks the assessment record for factual errors; Builds a comparable-sales evidence pack; Emphasizes the strict filing deadline.

🔵 Stable🕐 updated 2026-08-05 🔷 SkillSpec L3 pm-legal

Challenge an over-assessed property tax bill — check whether your assessment is too high, build the evidence, and file the appeal before the deadline. Use when asked to appeal my property taxes, my property assessment is too high, lower my property tax, or is my home over-assessed. Produces an over-assessment check (comparables vs your valuation), the evidence pack to build, the appeal steps and the strict deadline to watch, a realistic savings estimate, and what to expect at a hearing — flagging that process and rules are local. Not legal or tax advice.

🗣 Say this to your agent

“I think my property taxes are too high — how do I appeal?”“My home's assessed value went up a lot. Can I challenge it?”“Help me find comparables to appeal my property assessment.”“What evidence do I need to lower my property tax?”“When's the deadline to appeal my assessment and how do I file?”

What to give it

▸Your assessment — the assessed value, the tax bill, and the assessment date

▸Your property — size, features, condition, recent purchase price if any

▸Comparables — recent sales of similar nearby homes (or a request to help find them)

▸Any errors — wrong square footage, bedroom count, lot size, or condition on record

▸Location — determines the process, deadline, and appeal body

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Tests the assessment against real comparables/condition

✓Checks the assessment record for factual errors

✓Builds a comparable-sales evidence pack

✓Emphasizes the strict filing deadline

✓Estimates the annual savings

✓Flags that process is local / not tax-legal advice

⚠️ What it refuses to do

**Appealing on "it feels high"** with no comparables.

**Missing the short filing window.**

**Ignoring easy record-error wins.**

**Emotional hearing pitches** instead of comps and numbers.

**Asserting one process** across all jurisdictions.
