MLS PIN Public Remarks Character Limit

MLS PIN — the MLS Property Information Network, accessed through the Pinergy platform — is the dominant MLS across Massachusetts and much of New England. Its public-remarks field allows around 1,000 characters, an allotment MLS PIN expanded from a tighter previous limit. That is roughly 150 to 175 words: enough for two or three focused paragraphs, not enough to ramble. For agents working Greater Boston and the surrounding region, that limit shapes every description.

This guide covers the MLS PIN character limits, how to make 1,000 characters count, and the Fair Housing rules that apply regardless of length.

MLS PIN Character Limits by Field

MLS PIN serves Massachusetts and extends into Rhode Island, New Hampshire, and beyond. After expanding its public-remarks field, the allotment sits in the middle of the national range.

Field	Approximate Character Limit
Public Remarks	~1,000 characters
Expanded Firm/Agent Remarks	Additional agent-only space
Directions	Limited

Always confirm the current limit in your Pinergy listing-input screen — the counter there is authoritative and the network adjusts limits periodically.

Public Remarks is what syndicates to Zillow, Realtor.com, Homes.com, and consumer portals. At ~1,000 characters, MLS PIN is comparable to boards like ARMLS; see how it compares in our MLS public remarks character limits guide.

How to Write a Strong 1,000-Character MLS PIN Description

At 1,000 characters, the right length is the whole field, used intentionally. Treat every character as a decision.

Lead with the strongest feature. Buyers scan. "Renovated 1900s colonial two blocks from the commuter rail, with a fenced yard and off-street parking" lands harder than any generic opener — and off-street parking is gold in a Boston-area listing, so say it early.

Prioritize specifics over generics. Cut "move-in ready" and "must see." Add "new heating system (2024), refinished hardwoods, updated 200-amp electrical."

Don't repeat data fields. Beds, baths, square footage, and lot size are structured data in MLS PIN. Spend your remarks on what those fields can't capture — and on New England specifics buyers care about: heating type, parking, basement condition.

Format for mobile. Two or three short paragraphs beat one dense block. Our complete guide to MLS descriptions covers structure and pacing.

Fair Housing Compliance in MLS PIN Public Remarks

Character pressure can push agents toward shorthand that introduces violations. The federal Fair Housing Act prohibits discrimination based on race, color, religion, national origin, sex, familial status, and disability. Massachusetts state law adds further protected classes, including sexual orientation, gender identity, age, marital status, and source of income — one of the broadest sets in the country. MLS PIN membership requires compliance with both.

Watch for:

Neighborhood character statements. "Family-friendly," "quiet, established neighborhood," and "great community" imply who lives there. Describe the property. See our neighborhood description Fair Housing guide.

Source of income. Because Massachusetts protects source of income, language about who can or should buy — or rental copy hinting at income sources — carries extra risk in this market.

Familial status and age. "Starter home" and "perfect for empty-nesters" are risky outside legally designated 55+ housing.

The standard never changes: describe the property, not who should buy it. The listing description compliance checker gives a pre-submission pass.

Common MLS PIN Description Mistakes

Wasting characters on generics. On a 1,000-character field, filler crowds out the parking, heating, and update details New England buyers actually want.

Restating data fields. Don't repeat beds and baths.

Omitting region-specific selling points. Off-street parking, a updated heating system, and a dry basement are major in this market — name them.

No call to action. End with a clear next step.

Frequently Asked Questions

How many characters does MLS PIN allow in public remarks?

MLS PIN (Pinergy) allows approximately 1,000 characters in the Public Remarks field — roughly 150 to 175 words, after the network expanded the field from a smaller previous limit. That is room for two to three focused paragraphs. Lead with the strongest feature, favor specifics over generics, and don't repeat structured data fields. Confirm the current limit in your Pinergy input screen, since limits change periodically.

What is Pinergy versus MLS PIN?

MLS PIN (MLS Property Information Network) is the MLS itself; Pinergy is the software platform agents use to access it and enter listings. The character limits described here apply to the Public Remarks field as entered in Pinergy.

What happens if I exceed the MLS PIN character limit?

The Pinergy input will block or truncate text past the limit. Draft in a plain-text editor with a character counter and strip formatting before pasting, since hidden formatting characters can push you over even when the visible text fits.

Are Fair Housing rules different in Massachusetts?

The federal Fair Housing Act applies to all U.S. MLSs, including MLS PIN. Massachusetts state law adds several protected classes beyond the federal set — including source of income, sexual orientation, gender identity, age, and marital status — so listing language faces a broader compliance standard here.
