Fact checking AI in real estate: how to verify before you send

Fact checking AI in real estate means checking every number, date, and claim against a source you trust before you send it. It takes about ten minutes, and it protects your reputation, because AI writes with confidence even when it is wrong.

I'm Polly Keene, AI Trainer and Consultant and founder of Keene on AI. I spent seven years as a licensed REALTOR on a top producing San Antonio team, and I now teach real estate agents and REALTORS to use AI in plain language.

A wrong square footage in a listing, a made up sales figure in a seller update, or a rule stated incorrectly can cost you a client. AI gives you speed, and you supply the accuracy. This guide shows you what to verify, where to check it, and a one line prompt that makes AI point out its own risky claims.

Why does AI get facts wrong?

AI predicts likely words. It does not look up your MLS or know your listing. When it lacks a fact, it can fill the gap with something that sounds right. It also cannot see your market, so any local number it states without your data is a guess. The tone stays confident either way, which is why your review is the safeguard.

Agents know the risk. In a 2026 survey of 225 agents by Realtors Property Resource, 63% named accuracy as a top concern with AI, 47% worried about AI misreading market data, and only 48% felt confident using AI written content with clients. A short, repeatable check is what turns that worry into confidence.

What should you verify in AI drafts?

Check anything a client could rely on:

• Prices, days on market, sold and pending counts: check your MLS.
• Square footage, lot size, year built: check your listing sheet and the county appraisal district.
• Upgrade dates and features: check your seller's records and the listing agreement.
• Neighborhood and school claims: check official public sources, not AI.
• Legal, compliance, or contract statements: check with your broker or an attorney.
• Quotes, statistics, and named sources: check the original source, opened and read.

What prompt makes AI flag its own risky claims?

Add this line at the end of any request: after the draft, list every number, date, and factual claim I should verify. You can also ask afterward: what in this draft should I verify? This does not make the draft accurate. It gives you a checklist, so you know where to look first.

How do you fact check AI in real estate in ten minutes?

1. Ask the AI to list every number and claim to verify.
2. Copy that list into a note.
3. Check each numbered item against your MLS or listing sheet.
4. Open any linked source, and read the page yourself.
5. Delete any claim you cannot support.
6. Read the draft out loud, and change anything that sounds like a promise.
7. Send it, and save the checked prompt for next time.

If a claim matters and you cannot verify it, leave it out.

Can you use one AI tool to check another?

You can, but it is not enough. A second tool can catch inconsistencies, and a research tool like Perplexity links its sources so you can read them. The final check is still yours. Open the source, confirm the number, and make the call.

Where to go next

Save the verify line as a note on your phone, and add it to your next AI request. For the prompt habits that prevent errors in the first place, read how to write AI prompts for real estate.

Frequently asked questions

How do I know if AI content is accurate enough to use?

Verify every number, date, and claim against your MLS, your listing documents, or an original source. If you cannot verify a claim, remove it. Accuracy is your job, and speed is the AI's job.

Can AI make up statistics or sources?

Yes. AI can state invented figures or name sources that do not say what it claims. Open every source yourself, and never publish a number you have not confirmed.

How long does fact checking take?

About ten minutes for a seller update or listing description when you ask the AI for a verify list first. The habit gets faster with practice. Skipping it can cost you much more in a lost client.

Does fact checking apply to social media posts too?

Yes. Any post that states a market number, a rule, or a result should be checked. Posts about how you work can be lighter, but never post a figure you have not confirmed.

What prompt makes AI flag its own risky claims?

Add this line to any request: after the draft, list every number, date, and factual claim I should verify. You can also ask afterward, what in this draft should I verify? This does not make the draft accurate, but it shows you where to look first.

Where should I verify property facts?

Check prices, days on market, and sold counts against your MLS. Check square footage, lot size, and year built against your listing sheet and the county appraisal district. Check upgrade dates with your seller's records, and take legal or compliance questions to your broker or an attorney.

Can I use one AI tool to check another?

You can, but it is not enough. A second tool can catch inconsistencies, and a research tool like Perplexity links its sources so you can read them. The final check is still yours: open the source, confirm the number, and make the call.

What should I do if I cannot verify a claim?

Leave it out. A missing detail costs you almost nothing, and a wrong one can cost you a client or raise a compliance concern. If the claim matters, find a source you trust or ask your broker.
