MLS Listing Copy Generator

Key Information

An MLS listing copy generator creates property descriptions automatically from address, features, and agent-supplied selling points. BuildMyListing generates 150-250 word MLS descriptions that pass fair housing review, meet platform character limits, and include a compliance audit log. Output is ready to paste into any MLS input form without editing.

Pricing: Starting $99/month

Time Required: 2 minutes per listing

The Problem

Writing a strong MLS description takes 30-60 minutes per listing — and many agents still produce generic copy that misses key selling points or uses risky fair housing language without realizing it.

The Solution

BuildMyListing generates compelling, property-specific MLS descriptions from your input. Every draft is reviewed for fair housing compliance and sized to MLS platform limits before you see it.

Key Features

Property-Specific Copy

Our AI writes descriptions unique to each property using the features you input — not generic templates. Kitchen upgrades, primary suite details, lot size, and location attributes are woven in naturally.

Benefit: Descriptions that actually help buyers picture the home

MLS Platform Length Optimization

Most MLS systems accept 250-1,000 characters in summary fields and longer in full remarks. BuildMyListing generates descriptions sized for your target platform, with a concise hook for syndicated portals.

Benefit: Copy that fits without truncation on Zillow, Realtor.com, and your MLS

Fair Housing Pre-Review

Every description is scanned for protected-class language, coded neighborhood references, and lifestyle assumptions before output. Flagged phrases are replaced automatically.

Benefit: No liability review step needed before publishing

Regenerate and Refine

Not happy with the first draft? Regenerate with different tone (luxury, value-forward, investor-focused) or edit inline. Each version is logged in your listing file.

Benefit: Iterate quickly without starting over

How It Works

Input Property Details

Enter address, beds, baths, square footage, lot size, and three to five key selling points. The more specific, the better the output.

AI Generates and Reviews

Our AI writes a 150-250 word listing description and runs a simultaneous fair housing scan. Output is ready in under 2 minutes.

Copy, Edit, or Regenerate

Copy the description directly to your MLS input, make inline edits, or regenerate with a different tone. Each version is saved to your listing history.

Frequently Asked Questions

What is an MLS listing description and how long should it be?

An MLS listing description is the public-facing text that describes a property in the Multiple Listing Service. Most MLS systems accept between 250 and 4,000 characters in public remarks fields. The standard industry length is 150-250 words — long enough to highlight key features, short enough for buyers skimming on Zillow or Realtor.com.

What information do I need to generate a listing description?

Address, bed/bath count, square footage, lot size (for single-family), and three to five specific selling points — for example, 'recently remodeled kitchen with quartz counters,' 'primary suite with spa bath,' 'corner lot, no rear neighbors.' The more specific your inputs, the more differentiated the output.

Does BuildMyListing generate descriptions for condos, townhomes, and multi-family?

Yes. The generator works for all residential property types: single-family, condo/co-op, townhome, multi-family (2-4 units), manufactured home, and land. Enter the property type and relevant features — for condos, HOA amenities and floor level; for multi-family, unit mix and cap rate context.

Can I generate multiple tone variations for A/B testing?

Yes. BuildMyListing supports regeneration with different tones: standard, luxury, value-forward, and investor-focused. Run two versions and see which gets more showings requests — the platform logs each version in your listing history.

How does the fair housing review work in the listing copy generator?

Every generated description is scanned against a library of 200+ prohibited phrases — protected-class language, coded neighborhood references, and lifestyle assumptions. Flagged items are replaced automatically before output. A compliance log is included in your listing file showing what was changed and why.

Does BuildMyListing write Spanish or other language descriptions?

English is the primary output. Spanish-language descriptions are on the roadmap. For now, run the English output through a professional translation service — the structured, property-focused writing style translates cleanly.

Will MLS reviewers flag AI-generated listing descriptions?

No. MLS systems review listings for rule compliance (accurate data, no contact info in public remarks on some platforms), not for how copy was written. AI-generated descriptions are indistinguishable from human-written copy and meet all standard MLS rules.
