Multifamily Listing Descriptions: Tips for 2–4 Unit

Small multifamily properties — duplexes, triplexes, and fourplexes — attract two fundamentally different buyers, and most MLS descriptions serve neither of them well. The investor running cap rate calculations wants gross rent, unit configuration, and utility separation. The owner-occupant hunting for a mortgage offset wants livability, privacy between units, and neighborhood feel. Cramming both perspectives into a 500-character MLS remarks field requires a completely different approach than any single-family listing — and skipping it costs you showings from both groups.

Understanding Your Two Audiences: Investors and Owner-Occupants

Before you write a single word, decide which buyer is more likely to purchase this property — and lead with what they care about most.

The investor audience is primarily evaluating yield. They want to know:

• Current rental income. What are tenants paying right now? If units are occupied, include gross monthly rent and annual gross. If vacant, include market rate estimates based on comparables.
• Unit configuration. A 2/1 upstairs and a 1/1 downstairs have very different rent potential than two 2/1 units.
• Separately metered utilities. This is among the highest-value features for investors because separate meters shift utility costs to tenants. Lead with it.
• Cap rate and GRM. Most agents don't include cap rate calculations in MLS remarks (MLS rules and liability make this tricky), but a sophisticated buyer's agent will want the income numbers to run the math themselves.
• Recent capital improvements. A roof replaced in 2024, updated electrical panel, or new HVAC significantly affects a buyer's maintenance projection for the next 5–10 years.
• Vacancy history. Long-term tenants signal a stable property. Recent vacancies signal potential rent optimization — depending on the investor's strategy.

The owner-occupant audience is essentially buying a primary residence with rental income as a bonus — or a mortgage offset tool. They're asking:

• Which unit would I live in, and what's it like?
• How much separation is there between units? Can I hear my tenant through the floor?
• What would I net after paying the mortgage if I rented the other unit(s)?
• Is this neighborhood somewhere I actually want to live?
• Are any units currently occupied, and are those tenants staying?

For a duplex in a strong rental market, an owner-occupant might be able to cover 40–60% of their mortgage with rental income — a compelling pitch that deserves space in your description.

When the property leans toward investor buyers (higher unit count, currently rented, older building in need of updates), lead with income data. When it leans toward owner-occupants (two well-finished units, desirable neighborhood, strong schools), lead with livability and the house-hack math. For properties that genuinely attract both, write your MLS description with investor data first, then add a sentence about the owner-occupant opportunity.

What to Include in a Multifamily MLS Description

A 2–4 unit property has more material facts than a single-family home, and leaving out key details creates unnecessary friction in the showing process. Here's what to include and in what order:

1. Income summary (if occupied) Lead with gross monthly or annual rent. "Current rents: Unit 1 $1,850/mo, Unit 2 $1,600/mo. Gross annual income: $41,400." Investors skip listings that don't include this.

2. Unit breakdown Describe each unit's bedroom/bathroom count and any significant differences. "Unit 1 (upper): 3BR/2BA with in-unit laundry. Unit 2 (lower): 2BR/1BA with private patio."

3. Utility configuration "Separately metered gas and electric" is worth mentioning in the first paragraph. It meaningfully affects operating expenses and is a top investor filter. Shared utilities (especially water/sewer) should also be disclosed — buyers will find out during due diligence, and surprises breed renegotiations.

4. Recent improvements Roof, HVAC, windows, plumbing, and electrical updates belong in the listing. "New roof 2023, updated 200-amp panel, both units renovated 2022" reduces perceived risk and increases perceived value simultaneously.

5. Parking Note the number of off-street spaces and how they're allocated to units. Parking affects rent potential and tenant satisfaction, and buyers notice its absence.

6. Owner-occupant angle If the property is well-suited for a house-hack, say so: "Live in Unit 1 while Unit 2 generates rental income to offset your mortgage." This one sentence can double your showing requests from first-time investors and primary-home buyers using FHA financing.

7. Location efficiency Two sentences on proximity to transit, employment, and amenities. Keep it factual — address Fair Housing rules by describing physical proximity, not neighborhood character.

Fair Housing Compliance for Multifamily Listings

The Fair Housing Act applies to 2–4 unit properties in most circumstances. The one narrow exception is the "Mrs. Murphy exemption," which allows owner-occupants of properties with four or fewer units to discriminate in rental decisions — but this exemption does NOT extend to advertising. You cannot use discriminatory language in MLS remarks even if you technically qualify for the exemption.

Common compliance errors in multifamily listings:

• "Ideal for two professional couples" — familial status violation (excludes families with children)
• "Great for two young families" — the word "young" touches on age, and "families" can be read as exclusionary to single occupants
• "Quiet building, suitable for responsible adults" — implies children or certain applicants are unwelcome
• "No Section 8" — protected in 20+ states under source of income laws; check your jurisdiction
• Describing the neighborhood in coded demographic terms — national origin and race violations apply to location language, not just tenant descriptions

What to say instead:

Focus on the physical attributes of each unit and the property's income potential. Tenant profile is irrelevant to the listing — it belongs in the rental application process, not the MLS.

Multifamily listings also face an additional compliance wrinkle: if you describe one unit's renovations in detail and say nothing about another unit's condition, a buyer might later argue material facts were omitted. Be consistent in describing each unit's current state.

If the property currently has tenants, never describe the tenants in terms that suggest their demographics. "Currently tenanted with long-term stable tenants" is fine. Any demographic description of existing tenants — intentional or offhand — can create liability.

For detailed guidance on which words to avoid across all listing types, the discriminatory language in real estate listings guide is worth reviewing before submitting to MLS. For duplex-specific description examples, see duplex listing description tips for agents.

A Format That Works for Any 2–4 Unit Property

Multifamily listing descriptions don't need to be complicated — they need to be complete. Start with income, then unit breakdown, then the key investor metrics (separately metered utilities, recent improvements), then parking, then a one-sentence owner-occupant opportunity if applicable. Close with two sentences on location. Run the copy through a Fair Housing compliance check before publishing — tools like ListingKit scan every word against all 8 protected classes and generate a compliance certificate, which is particularly useful for investment property listings where the stakes are higher and the buyer pool is more sophisticated.

Frequently Asked Questions

Should I include current rental income in my MLS description?

Yes, if the units are occupied. Gross monthly rent and annual gross income are material facts for investment buyers and are expected in multifamily listings. Omitting rental income makes your listing harder to evaluate and pushes buyers to make assumptions, which often leads to lowball offers or no offers. If units are vacant, include market-rate rent estimates with a note that they reflect current comparable rents rather than actuals.

What''s the character limit for multifamily MLS remarks?

It depends on your board. Most MLS systems allow 500–1,000 characters for public remarks, though some — like NWMLS — have specific limits that differ by property type. For investment properties, some boards allow an additional agent-only remarks section where you can include income details, lease terms, and expenses. Check your local board rules and prioritize income data and unit configuration in the public-facing remarks. See MLS description character limits by board for a state-by-state reference.

How do I describe a duplex to attract owner-occupants?

Describe the unit they would live in first — bedrooms, bathrooms, finishes, and any premium features. Then quantify the rental offset: "Unit 2 currently rented at $1,600/month, enough to cover roughly 40% of a mortgage at today''s rates." Include separation details (concrete construction, separate entrances, independent HVAC) that address privacy concerns. Owner-occupants buying a duplex are almost always nervous about living next to a tenant — proactively addressing that concern in the listing converts more showings to offers.

Do Fair Housing rules apply differently to 2–4 unit properties?

The advertising rules are the same regardless of unit count. The "Mrs. Murphy exemption" technically allows owner-occupants of four-or-fewer-unit properties to discriminate in tenant selection — but it does not apply to MLS advertising or any public listing. In practice, you should write your multifamily listing exactly as you would any other listing: describe the property, not the preferred occupant. Review your copy against the fair housing compliant listing descriptions guide before submitting to your MLS board.
