Prepare property tax protest evidence for homeowners.

In short: an AI-agent-run business you oversee about an hour a week. Tools cost $30–$85/mo, agent setup is advanced, and our estimate is 40 packets a month × $49 = $1,960/mo.

How it makes money: Charge homeowners $49 per protest packet built from county appraisal data that they file themselves; refund it if the value isn’t cut.

Where this came from (Reddit)

Homeowners overpay because building protest evidence from county records takes hours, and contingency services keep a share of the savings.

The threads (in our words)

A Travis County homeowner who protested twice says the hard part is the evidence, not the filing: a table of similar homes the district values lower per square foot. They plan a $79 packet built from county data that owners file themselves; commenters’ price answers ranged from $20–30 to $79, one asked for a money-back guarantee, and one noted that recent sales comps are stronger evidence.

Who it’s for

Homeowners in counties with a yearly appraisal protest window (Texas counties, Cook County and similar).

Adapt it to your industry

Start with one niche or customer type, then expand.
Ask your first 10 customers what they would pay before you build more.
Keep a human check on anything sent in a customer’s name.

Step by step

Start with one county whose appraisal records are public, and read its protest rules and deadlines.
Have the agent find homes like the customer’s (size, age, neighborhood, one or two stories) and compare assessed value per square foot.
Generate a short evidence packet: comparison table, photos the owner adds, and a plain summary of the requested value.
Owners review and file through the county’s own portal; the agent sends deadline and hearing reminders.
Charge a flat fee per packet through Stripe and refund it if the value is not reduced.
Publish one SEO page per county with deadlines and how the protest works.

What they did

An agent pulls the county appraisal district’s own records for similar homes, builds a comparison table and a ready-to-file evidence packet, and reminds the homeowner of each deadline. We designed this business from real Reddit threads; it is an idea for you to build, not a description of the posters’ businesses.

How it went

Found on Reddit in r/AustinTX (1 thread). Upvote and comment counts weren’t retrievable, so none are shown. On X, 40 posts matched our search for this idea in the 7 days to 2026-10-20.

Worth knowing

Use only public county data within each site’s terms; owners file their own protest; it is not legal or tax advice; protest windows are seasonal (spring in Texas), so expect most sales in a few months.
