Here are my Residential Worksheet and the Comparable Sales List the state used for my property assessment. Analyze my chances of an appeal, point out any line items that look overvalued, pick the best comparable sales and write the text I should paste into the online Supervisor's Review form. Take an aggressive position and list 3–5 comps.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish. Goal: Decide whether my property tax assessment is worth appealing and prepare the appeal text and evidence. Questions to ask me first: - What county and state is the property in? - Do you have the assessor's worksheet and comparable sales list? - What's the appeal deadline and filing method? Inputs (fill in or confirm): - Assessment notice and worksheet: [DOCUMENTS] - Comparable sales or neighbor assessments: [LIST] - Property details the assessor may have wrong: [DETAILS] - Deadline and filing method: [DATE AND PORTAL OR FORM] - How firm to be: [CONSERVATIVE OR AGGRESSIVE] Rules: - Use only comparable sales and figures from my documents. - Point out any line items that look overvalued and why. - Follow my county's appeal steps; if you're unsure of a rule, say so. - Show the estimated tax savings as an estimate. Checkpoint: Show me the comps you'd use and the value you'd ask for, and wait for my OK before drafting the appeal text. If you get stuck: If my documents don't support an appeal, tell me plainly instead of writing one. Verify before you finish: Check every number in the appeal against the documents and confirm the deadline. Output: Appeal text ready to paste, a one-page comps table and a list of attachments. Done when: I can file the appeal before the deadline.

Outcome
Jim Wang of Wallet Hacks fed ChatGPT the Residential Worksheet and Comparable Sales List behind a $1.3 million Maryland assessment ($400,000 land and $900,000 improvements). ChatGPT compared the property with the sales list, flagged line items that seemed high, such as the finished basement and pool, and wrote the text for the written Supervisor's Review form using an aggressive stance with 3–5 comparable sales. Howard County replied on March 26, cutting the structures value by $25,000, which lowered the property taxes by $362.50. Wang says the appeal took about 15 minutes with ChatGPT. ChatGPT itself called the result a 'we looked at it' adjustment, so Wang filed a second written appeal with a price-per-square-foot argument: about $247 per square foot versus $180–$235 for neighbors, with a 1-page PDF exhibit ChatGPT made. That appeal was still pending.
