How Long Should an MLS Description Be?

MLS description length is one of those questions that gets a lot of confident wrong answers. "Keep it under 500 characters." "Write as much as you can." "Buyers don't read long descriptions." "Luxury listings need 1,000 words." Each of these positions has adherents — and each is more nuanced than the confident assertion suggests.

The correct answer depends on three things: your MLS board's hard character limit, the property type and price point, and what the research actually shows about buyer reading behavior. This guide covers all three.

MLS Character Limits: The Hard Ceiling

Before discussing optimal length, understand the constraint. Every MLS board has a character limit on the public remarks field. This is the maximum, not the target.

Character limits vary significantly by board:

• MRIS (Mid-Atlantic): 2,048 characters
• CRMLS (Southern California): 500 characters (notably short)
• MLSListings (Northern California Bay Area): 2,500 characters
• NWMLS (Pacific Northwest): 500 characters
• RMLS (Portland): 1,500 characters
• BRIGHT MLS (Mid-Atlantic): 2,000 characters
• SABOR (San Antonio): 1,000 characters

These limits are measured in characters (including spaces), not words. A 500-character limit is roughly 75-100 words. A 2,500-character limit is roughly 400-500 words.

Action item: Find your board's actual character limit before writing any description. Do not assume — look it up in your MLS system's help documentation or create a test listing and count the field maximum.

What Boards with Short Limits Require

Boards with 500-character limits (CRMLS, NWMLS) force a fundamentally different writing approach than boards with 2,000-character limits. At 500 characters, you have roughly 80 words. Every word has to earn its place.

For short-limit boards:

What to include: Address (sometimes), the property's single most compelling feature, core specs if they are not captured in data fields, one specific detail that differentiates this listing.

What to cut: All generic filler ("spacious," "bright," "move-in ready"), any detail that appears in the MLS data fields (beds, baths, sqft), showing instructions, and anything non-marketing in nature.

Example (under 500 characters): "Corner-lot craftsman with a rare 3-car garage, renovated chef's kitchen, and a private backyard pool on a quiet Noe Valley street. Primary suite added 2021 with heated floors and soaking tub. Coveted Alvarado Elementary district. Open Saturday 1-4."

That is 274 characters. It covers: differentiating features (corner lot, 3-car garage, pool, Noe Valley location), renovation signal (kitchen), specific improvement (primary suite addition with date and features), school district, and open house. Nothing wasted.

What Boards with Long Limits Allow

At 2,000-2,500 characters, you have roughly 300-450 words. This is enough for a full narrative description that covers the property's exterior, main living areas, kitchen, bedrooms and baths, outdoor spaces, and practical details.

The question with long-limit boards is not "can I write this much?" but "does this listing warrant this much?"

Optimal Length by Property Type and Price Point

Research on buyer behavior suggests that description length has diminishing returns — and that the optimal length varies by property category.

Entry-Level and First-Time Buyer Properties ($200K-$500K)

Optimal range: 150-300 words (approximately 800-1,500 characters)

First-time buyers are information-hungry and tend to read descriptions carefully. They are learning the process and want to understand what they are considering. Descriptions in the 150-300 word range are long enough to be thorough and short enough to be readable.

Avoid padding. First-time buyer descriptions benefit from specificity about what is included (appliances, W/D, storage), school district names, and practical details about the condition and any recent improvements.

Move-Up Buyer Properties ($500K-$1M)

Optimal range: 200-350 words (approximately 1,000-1,800 characters)

Move-up buyers are often trading up from a property they already own. They have more specific requirements and read descriptions with a filter — they are looking for specific features (garage size, basement, primary suite configuration) and will dismiss listings quickly if those are not evident.

Descriptions at this price point should front-load the differentiating features and cover the property comprehensively. Buyers at this level have more choices and more patience for thorough descriptions.

Luxury Properties ($1M+)

Optimal range: 300-600 words (approximately 1,500-3,000 characters)

At the luxury tier, description length is itself a signal. A 200-word description for a $3 million property suggests either the agent did not take time to describe it properly or there is less to say than the price implies. Luxury buyers expect comprehensive descriptions and read them before deciding to visit.

Use the full character limit available. For boards with 2,500-character limits, this is approximately 400-450 words. If your board has lower limits for luxury properties, supplement with additional materials — a property website, a PDF brochure, or a detailed email to buyer's agents.

Investment Properties

Optimal range: 150-250 words of description + financial data

Investment property descriptions should be shorter on the marketing prose and more thorough on the financial specifics: income, expenses, cap rate, lease terms, and improvement history. Investors do not make decisions based on aspirational language — they make decisions based on numbers.

A well-structured investment property description leads with the income profile, documents the mechanical condition, states the financing terms, and closes with the offer process. 200-250 words handles this well.

Vacant Land

Optimal range: 100-200 words

Land descriptions should cover the facts: acreage, zoning, utilities, topography, access, and proximity to key destinations. There are no rooms to describe. Padding a land description with lifestyle language often obscures the practical information buyers need.

What Buyers Actually Read

Several studies have examined buyer attention to listing descriptions. The consistent finding is that buyers use descriptions as a qualification filter — they are scanning for specific information rather than reading linearly.

The NAR's 2025 Profile of Home Buyers and Sellers found that 78% of buyers said they read listing descriptions "carefully" or "very carefully" before requesting a showing. This contradicts the common claim that "buyers don't read descriptions."

However, buyers do not read descriptions with equal attention throughout. Eye-tracking studies consistently show:

• The first 50-100 words receive disproportionate attention
• Feature-specific phrases (school district names, renovation details, appliance brands) capture attention more than prose paragraphs
• Bold formatting, bullet points, and visual breaks increase reading depth

Practical implications for length:

1. The opening lines are the most important — lead with the property's best feature, not a generic greeting
2. Use scannable formatting (bullet points for feature lists) where your MLS platform supports it
3. Length matters less than density — 200 words of specific information outperforms 400 words of generic language

The Case Against Short Descriptions

"Buyers don't read them anyway" is the rationalization most often used for short descriptions. The evidence does not support it.

Properties with below-average description length in their price range show lower showing-request rates in multiple industry analyses. The mechanism is probably not that buyers read every word — it is that short descriptions signal low agent effort, which reduces buyer confidence in the listing.

A property with a 50-word description competing against properties with 250-word descriptions suffers from a quality signal problem, not just an information problem. Buyers and buyer's agents draw inferences about listing agent engagement from description quality and length.

---

The Case Against Padded Long Descriptions

The opposite failure — padding a description to hit a length target — is equally damaging.

Generic language ("spacious," "beautiful," "charming," "must-see") adds characters without adding value. Buyers skip over these phrases because they cannot be evaluated or acted on. A 400-word description that contains 200 words of specific information and 200 words of generic filler is not better than a 200-word description that contains 200 words of specific information. It is worse — it makes the buyer work harder to extract the useful content.

The test: Read the description and underline every sentence that contains a specific, verifiable fact about this property. If fewer than 70% of sentences are underlined, the description needs editing.

Character Count for AI-Generated Descriptions

AI listing tools like ListingKit generate descriptions calibrated to standard MLS character limits by default. Most tools target 300-500 words (approximately 1,500-2,500 characters), which fits the 2,000+ character boards common in most U.S. markets.

If your board has a shorter limit (CRMLS's 500 characters, for example), check whether the tool allows you to specify a shorter target length. If it does not, the generated description will need manual condensation for the public remarks field.

Some agents use longer AI-generated descriptions for property websites and short-form versions for the MLS public remarks — a reasonable approach for boards with restrictive character limits.

Summary: Length Guidelines by Category

Property Type	Price Range	Target Length	Character Range
Entry-level residential	Under $400K	150-250 words	750-1,250 chars
Mid-range residential	$400K-$800K	200-350 words	1,000-1,750 chars
Move-up residential	$800K-$1.5M	250-400 words	1,250-2,000 chars
Luxury residential	$1.5M+	350-600 words	1,750-3,000 chars
Condo/townhome	All price points	150-300 words	750-1,500 chars
Investment property	All price points	150-250 words + financials	750-1,250 chars
Vacant land	All price points	100-200 words	500-1,000 chars

All ranges assume a board with 2,500+ character limit. Adjust downward proportionally for boards with lower limits.

The Bottom Line

The right MLS description length is long enough to be thorough and specific, short enough to be readable, and never longer than your board's character limit. At most price points, this means 200-400 words.

The quality of what you write matters more than the quantity. Specific, verifiable, property-accurate content in 200 words outperforms generic padding in 500 words every time.

Know your character limit. Know your buyer. Write to the intersection.
