Open Zillow on a phone, search a neighborhood, and scroll. Each listing card shows a photo, a price, beds and baths, and a snippet of the description. The snippet cuts off at roughly the first 250 characters, with a "...Read more" link to expand the rest.
That snippet — not your full description — is what convinces a buyer to tap into the listing. If your first sentence is "Welcome to this stunning property, perfectly situated in a desirable location," you've burned the only impression most cold scrollers will ever get.
The agents whose listings get more saves and views are usually the ones whose first sentence reads as a complete idea on its own, with the strongest concrete fact about the property in it.
The 250-character rule
Zillow doesn't publish an official character limit for descriptions, but the feed-card truncation point is consistent across mobile and desktop: descriptions get cut at roughly 250 characters before "Read more." Zillow's own seller guide reinforces the practical version of this — they recommend leading with the property's standout feature and front-loading the most engaging detail.
The implication for structure:
Your first sentence must work as a standalone hook. If a reader saw only the first sentence in a search-result card, would they still know what makes this listing interesting? If yes, you've written a feed-friendly opener. If no, rewrite.
The second sentence is your second chance. Some Zillow display contexts show two sentences before truncation; others cut earlier. Treating sentences one and two as a paired hook gives you margin.
Anything past the truncation point only works for buyers who already tapped in. That's not nothing — they're a higher-intent audience — but it's a smaller audience than the cold-scroll one. Don't put your most differentiating fact in paragraph three.
What good first sentences look like
A weak opener leads with adjectives or with a non-fact:
Welcome to this beautiful home in the heart of a desirable neighborhood, where modern comfort meets timeless charm.
A strong opener leads with a concrete, specific differentiator:
Three-bedroom 1928 Craftsman on a 4,500-square-foot lot, fully renovated in 2023 with new HVAC, new roof, and a primary suite addition.
The second version is roughly the same length and gives the buyer four facts they can use to assess fit — era, size, recency of renovation, suite layout — before they decide to tap in. The first version gives them nothing actionable.
The pattern that works most consistently: property type + era or build year + size + the single strongest differentiating feature. Then the supporting paragraphs.
The Zillow Talk vocabulary data
This part is interesting because it's data-grounded rather than vibes-based.
In 2014, Zillow analyzed a dataset of roughly 24,000 home sales for the book Zillow Talk and identified specific words in listing descriptions that correlated with higher- or lower-than-expected sale prices. The book is a decade old, but the underlying findings have been replicated in subsequent analyses and the vocabulary patterns hold up. CBS News summarized the original data, Lucid Realty wrote a clean walkthrough, and AARP recapped the takeaways for a general audience.
Words that correlated with higher-than-expected sale price:
- "Luxurious" — +8.2% for bottom-third homes (counterintuitively, the word lifts the least expensive listings most, possibly because it signals premium positioning)
- "Captivating" — +6.5% for top-third homes
- "Stainless," "granite," "tile," "remodel," "remodeled," "upgraded," "updated" — all positive correlations
- "Landscaped," "pergola" — positive correlations on outdoor features
- Words that signal specific, recent improvements — generally outperformed unspecified or aspirational language
Words that correlated with lower-than-expected sale price:
- "Fixer" — −11.1%, the strongest single negative correlation
- "TLC," "cosmetic" — flagged as needing-work signals
- "Investment," "investor," "potential," "opportunity," "bargain" — language that prices the listing as a project, not a finished property
- "Nice" — interesting outlier; the word is so generic it seems to signal a writer who couldn't find anything specific to say
The mechanism: specific, factual, premium-implying language correlates with higher sale prices because it accurately describes properties that ARE premium. The vocabulary doesn't make a worse property sell for more — it identifies and flags the properties already capable of commanding the price. Writing "captivating" about a property that isn't captivating won't move the needle. Writing "remodeled" when the property has been remodeled, and getting specific about what was remodeled and when, will.
The practical implication for your description:
Use the strongest factual vocabulary your property actually supports. "Kitchen with quartz counters and stainless appliances" outperforms "updated kitchen." "HVAC 2021, roof 2022" outperforms "well-maintained."
Avoid project-language unless the property is actually a project. "Potential" and "opportunity" are honest if you're listing a true fixer; they're price-destroying if the property is move-in ready.
Don't write "nice." It's the verbal equivalent of having nothing specific to say.
Why your paragraphs probably get flattened
A practical gotcha worth knowing: Zillow handles multi-paragraph formatting inconsistently across entry paths. A 2018 deep-dive by web developer Aaron Gustafson documented how Zillow's various submission flows treat line breaks — direct agent entry, MLS syndication, and Zillow Showcase all behave slightly differently. In several paths, paragraph breaks get stripped entirely and the description displays as one long block of text.
That doesn't mean stop writing in paragraphs. It means:
Write each sentence so it reads cleanly without paragraph breaks. Don't depend on a paragraph break to signal a topic shift; let the sentence content do it.
Treat the first 250 characters as a complete unit. They have to work as a feed-card snippet whether the rest renders as paragraphs or as a blob.
Keep paragraphs short anyway. Redfin's official house-description guidance recommends 2–3 sentences per paragraph, which is also Redfin's truncation-friendly recommendation. If your paragraphs render, they're scannable. If they get flattened, the short sentences are still readable.
What length actually performs
Zillow's research on listing engagement gives some useful benchmarks for what "good" looks like on the platform: 250 views per day correlates with a roughly 75% chance the listing goes pending within two weeks; 500+ views per day often signals an above-list sale; 5 saves per day in the first week typically means pending within 7 days. Inman's 2025 follow-up updated the analysis.
Description length plays into engagement, but probably not the way most agents think. The Zillow Talk analysis found that longer descriptions correlated with higher sale prices, but the relationship plateaued around 250 words. Past that, the marginal value of additional copy dropped off sharply.
So: aim for about 250 words. Less than 100 reads as low-effort. More than 350 starts to feel like the writer is filling space. Around 250 is enough to seat a strong opener, two or three differentiating-feature paragraphs, and a brief setting-or-context close — without the diminishing-returns problem.
Before / after
A real-world-shaped rewrite to make the rules concrete.
Before (247 characters, first sentence — generic, adjective-heavy):
Welcome to this stunning, move-in-ready home in a desirable neighborhood. Perfectly situated with modern updates throughout, this beautiful property offers everything today's discerning buyer is looking for in a sought-after location.
That entire snippet is what most cold scrollers see, and there's not a single property fact in it. The buyer has no reason to tap.
After (243 characters, first sentence — concrete, fact-led):
Three-bedroom 1928 Craftsman on a 4,500-square-foot corner lot, renovated 2023: new HVAC, new roof, refinished oak floors, and a primary suite added off the back. Original built-ins and trim preserved. Walk through the open kitchen to a covered patio.
Same length. Eight concrete facts. The buyer scrolling Zillow knows immediately whether this property is worth their tap.
The summary rule
Your first 250 characters are an ad. Write them as one. Lead with the strongest specific fact, use vocabulary your property actually supports, and don't waste the line on adjectives that could describe any home in the feed.
ListingToolkit's portal-description output is built around the 250-character feed-card rule. The generator front-loads the strongest concrete differentiator from your property facts, sizes descriptions to the ~250-word engagement sweet spot, and uses the Zillow Talk vocabulary research to favor language that correlates with above-expected sale prices.
