AI Prompts for Real Estate Listings That Don't Sound Like AI

Most "AI listing description" prompts fail for one boring reason: they don't respect the reality of real estate data.

Real listings are a messy blend of hard constraints (beds, baths, HOA rules, square footage, disclosures), soft positioning (who's the buyer, what's the vibe), and platform limitations (MLS character caps, banned phrases, fair housing). If you prompt like you're writing a lifestyle blog post, the model fills in gaps with guesses. In real estate, "guesses" are how you end up with a liability.

So I don't treat the model like a copy machine. I treat it like a junior writer who needs a tight brief, a strict definition of done, and a way to ask questions before it makes stuff up.

That mindset lines up with what research keeps showing: prompting is a powerful lever for output quality, but it's not the only lever-and single generations are noisy. You should expect variance and plan for it, not be surprised by it [2]. And if you want consistency at scale, you don't just "try a better prompt." You run a small prompt system: generate, verify, revise.

The core technique: stop prompting for copy, prompt for a workflow

When you ask for "a great description," the model has to invent a process. It will often invent facts too. What works better is giving it a workflow that forces clarity and reduces hallucination risk.

A useful mental model comes from agent evaluation research in marketing analytics: multi-step tasks fail when the model skips verification steps, uses wrong parameters, or drifts in long chains of reasoning [1]. Writing a listing sounds simpler than analytics, but the failure modes rhyme: wrong neighborhood claims, wrong distances, wrong school info, wrong "recently renovated" assertion, and so on. The fix is the same idea: explicit steps, explicit inputs, and explicit boundaries.

Here's the workflow I use for listing copy:

First, make the model extract and normalize your facts (so it's anchored). Then have it produce a draft under platform constraints. Then have it run a compliance and "no-new-facts" check against the input. Then, if you want to get fancy, generate multiple variants because sampling variability is real [2].

This is also where automated prompt improvement can help. Prompt-optimization research shows you can systematically refine instructions (and even use a judge model) to get more consistent adherence to constraints and formatting [3]. You don't need to build a full prompt agent to benefit from that idea-you just need to structure prompts so they're easy to evaluate and iterate.

My "Listing Brief → Draft → Audit" prompt template (copy/paste)

This is the one template I'd actually save in your CRM snippets. It's intentionally structured. You can feed it into any decent LLM.

You are a real estate listing copywriter and editor.

Goal:
Write a listing description that is accurate, compelling, and compliant.
Never invent facts. If something is missing, ask questions first.

Step 1 - Clarifying questions (only if needed):
If any required field is missing or ambiguous, ask up to 6 questions.
Do NOT draft until questions are answered.

Step 2 - Draft outputs (after the brief is sufficient):
Create 3 versions:
A) MLS version: 750-900 characters, no emojis, no all-caps, no exclamation points.
B) Zillow/website version: 150-220 words, skimmable, 1 short paragraph per idea.
C) Social caption: 40-70 words + 5 hashtags (no location hashtags unless provided).

Hard constraints:
- Use ONLY facts from the Listing Brief.
- Do not mention schools, crime, walkability scores, or commute times unless explicitly provided.
- Avoid fair-housing risk phrases (e.g., "perfect for families," "safe neighborhood," "exclusive community," "walking distance to churches").
- No "best," "rare," or "won't last" unless I explicitly approve.

Style:
- Concrete and sensory, but grounded in facts.
- Prioritize the top 5 differentiators.
- If there is a potential negative (e.g., HOA, street noise, no garage), reframe honestly without hiding it.

Step 3 - Audit:
After drafting, output an Audit section with:
1) "New facts introduced" (should be NONE; list any if found)
2) "Potential compliance issues" (list any phrases to revise)
3) "Assumptions detected" (list any)

Listing Brief (source of truth):
- Address (optional for public): {ADDRESS}
- City/Area: {CITY_AREA}
- Property type: {TYPE}
- Beds/Baths: {BEDS}/{BATHS}
- Sq ft: {SQFT}
- Lot size: {LOT}
- Year built: {YEAR}
- Parking: {PARKING}
- HVAC: {HVAC}
- Key upgrades w/ dates: {UPGRADES}
- Interior highlights: {INTERIOR}
- Exterior highlights: {EXTERIOR}
- Community/HOA details: {HOA}
- Neighborhood amenities (only verified): {AMENITIES}
- View/natural light/noise notes: {NOTES}
- Disclosures/constraints: {DISCLOSURES}
- Target buyer (optional): {BUYER}
- Tone (choose): modern | warm | luxury | minimalist | playful | classic

What I like about this template is that it's hard for the model to "wander." It forces the model to either ask questions or stay inside the brief. And it gives you an audit trail that catches most nonsense before it hits MLS.

Platform-specific prompts that fix common listing pain

Most teams don't need more adjectives. They need tighter formats.

Here are a few focused prompts I use a lot.

1) "Feature bullets that don't sound like a brochure"

Using ONLY the Listing Brief below, write 8 feature bullets.
Rules:
- Start each bullet with a concrete noun phrase (e.g., "Quartz kitchen," "Covered patio," "Vaulted ceilings").
- Each bullet max 10 words.
- No hype words (stunning, gorgeous, luxurious).
- No claims about schools or safety.

Listing Brief:
{PASTE BRIEF}

2) "Agent remarks vs. public remarks"

Split the copy into:
1) Public Remarks (consumer-facing): 120-160 words.
2) Agent/Private Remarks: 60-90 words, factual, includes showing instructions placeholders.

Constraints:
- Public: lifestyle + top differentiators, but no new facts.
- Private: call out known quirks neutrally (HOA limits, parking, access).

Listing Brief:
{PASTE BRIEF}

3) "Price-change rewrite" (keep it honest)

We just changed the list price. Rewrite the MLS description to reflect a refreshed positioning.
Do not mention the old price or say "priced to sell."

Output:
- Revised MLS description (750-900 characters)
- 3 alternative lead sentences (1 line each)

Listing Brief:
{PASTE BRIEF}
Positioning angle:
{E.G., "best value for updated 3/2 in this pocket", "move-in ready condo with low-maintenance lifestyle"}

Practical examples: what real users do that actually helps

Community advice is often noisy, but a few patterns show up repeatedly in how people get better outputs.

One is the "two prompt method": first ask the model to ask you questions, then draft after you answer [4]. That's not just a productivity hack-it's a hallucination-reduction move. It creates a safe escape hatch: the model can request missing info instead of inventing it.

Another is using bracketed placeholders so you can reuse prompts like templates across many properties [4]. In real estate, this is huge, because you're repeating the same structure across wildly different homes.

And the best trick, in my experience, is showing the model examples of the tone you want. Community posters phrase it as "show examples, don't just describe what you want" [4]. For brokerages, that can mean past high-performing descriptions (that you own) as a style anchor-then you still force "no new facts" with an audit.

The part people miss: generate multiple drafts on purpose

If you generate one listing description and treat it as "the model's answer," you're setting yourself up for frustration. Output variance is a built-in feature of how these systems behave, especially on creative writing [2]. That doesn't mean prompting is useless. It means your workflow should expect to sample a few candidates, then select and polish.

A simple, low-tech version is: generate 3 MLS versions, pick the best lead sentence, then regenerate the body with that lead locked. If you're building product, you can formalize this with a "judge" step, an idea that shows up in prompt optimization research: compare variants pairwise, pick the best under your rubric, then iterate [3].

Closing thought: treat listing copy like a controlled document, not a vibe

If you want your real estate descriptions to stop sounding like AI, don't chase "more human" prompts. Chase tighter briefs, tighter constraints, and a built-in audit.

Try this on your next listing: run the template once, answer the clarifying questions, generate three variants, and only then edit like a human. You'll get faster drafts, fewer compliance headaches, and copy that feels intentional instead of synthetic.
