Flat Fee MLS vs Realtor: Real Costs, Fees, and Net‑Proceeds Math

Opening hook:
On a $400,000 home, a traditional realtor can shave $22,000‑$24,000 off your net proceeds, while a flat‑fee MLS listing often leaves you $4,000‑$6,000 more in the bank.

Direct answer: How much do you keep?

A flat‑fee MLS service usually costs $500‑$1,200 per listing plus optional add‑ons. A full‑service realtor charges 5%‑6% of the sale price, which translates to $20,000‑$24,000 on a $400,000 home and $37,500‑$45,000 on a $750,000 home. The net‑proceeds gap can reach $15,000‑$20,000 when you compare the two models, after typical closing costs.

What you pay for each model

Flat‑fee MLS

Item	Typical 2026 cost	What you do
MLS listing fee	$395‑$550	Upload photos, description, and price
Optional buyer‑agent compensation (often 2.5%‑3%)	$10,000‑$22,500 on $400k‑$750k homes (paid from sale proceeds)	You set the amount; the buyer’s agent receives it at closing
Transaction coordination (optional)	$300‑$600	Coordinator prepares disclosures, reviews contracts, and tracks deadlines
Marketing add‑ons (virtual tour, premium photos)	$150‑$400	You choose based on budget and market competitiveness

You keep control of showings, negotiations, and any price adjustments.

Full‑service Realtor

Item	2026 average rate	What you get
Listing agent commission	2.5%‑3% of sale price	Marketing, staging advice, professional photography
Buyer‑agent commission (usually split)	2.5%‑3% of sale price	Paid from proceeds; buyer’s agent handles buyer side
Total commission	5%‑6% of sale price	All‑in service from listing to closing
Additional fees (marketing, escrow)	Often bundled	May appear as line‑items on the closing statement

The commission covers labor, exposure on dozens of MLS portals, and the agent’s network of buyers.

Net‑proceeds math – step‑by‑step

Start with the agreed sale price.
Subtract the flat‑fee MLS cost (listing fee + any add‑ons you selected).
Subtract the buyer‑agent compensation you promised in the MLS (if you offered 2.5% on a $400k home, that’s $10,000).
Subtract typical closing costs (title, escrow, recording, and lender fees), usually 1%‑1.5% of the sale price.
Result = net proceeds when you go the flat‑fee route.

For a realtor, replace step 2 with commission = sale price × commission rate (5%‑6%). The rest of the steps stay the same.

Example calculations

Scenario	Sale price	Flat‑fee MLS fees	Buyer‑agent comp.	Closing costs (1.25%)	Net proceeds (Flat‑fee)	Realtor commission (5.5%)	Net proceeds (Realtor)
Home A	$400,000	$950 (listing + $400 coordination)	$10,000 (2.5%)	$5,000	$383,050	$22,000	$363,000
Home B	$750,000	$1,200 (listing + $500 coordination)	$22,500 (3%)	$9,375	$717,875	$41,250	$688,500

All numbers are 2026 averages. Local fees may differ; always confirm your area’s exact rates.

When flat‑fee MLS is the smarter choice

Situation	Why you benefit
You have a flexible schedule	You can show the home on evenings or weekends, eliminating the need for an agent’s availability.
You’re comfortable reviewing offers	You can evaluate contingencies, counter‑offer, and accept a price that meets your target without a middleman.
Property is priced competitively	In a balanced market, a clean MLS listing often attracts enough buyer agents to generate offers without extra marketing spend.
You own a modest‑priced home (< $500k)	Flat‑fee costs stay under $1,200, far less than a 5%‑6% commission that would exceed $25,000.
You already have a trusted transaction coordinator	Adding a $400 coordinator gives you professional paperwork support while still saving thousands on commission.

When a full‑service realtor may earn you more

Situation	Why the commission can pay off
Home needs extensive staging or repairs	Realtors often provide staging consultations and have contractor networks that can boost the final price enough to cover their fee.
You live out of state or travel frequently	An agent handles showings, lock‑box access, and buyer communication while you focus on work or family.
You expect multiple offers or a bidding war	Experienced agents use timing, escalation clauses, and buyer‑agent relationships to drive the price upward, sometimes adding 2%‑4% to the sale price.
You lack confidence in contract law	Realtors review offers, manage disclosure deadlines, and coordinate with attorneys, reducing the risk of costly legal mistakes.
You prefer a hands‑off experience	Full service means the agent does everything from marketing to closing, letting you keep your attention on other priorities.

Frequently Asked Questions

1. Is flat‑fee MLS worth it for a $400,000 home?
Yes, if you can manage showings and negotiations yourself. You’ll typically keep $4,000‑$6,000 more than with a 5.5% commission after accounting for buyer‑agent compensation and closing costs.

2. How much does a realtor earn on a $300,000 house?
At a 5.5% commission, the agent’s gross earnings equal $16,500. The amount you actually pay may be lower if the agent splits the fee with a buyer’s broker, but the total cost to you remains around that figure.

3. What are the main disadvantages of flat‑fee MLS?
You lose the agent’s network, staging resources, and negotiation expertise. You also must schedule showings, field buyer questions, and handle offers, which can extend the time on market if you’re unavailable.

4. Can I add a transaction coordinator to a flat‑fee MLS listing?
Absolutely. Adding a coordinator for $300‑$600 gives you professional paperwork support while still avoiding the 5%‑6% commission. Many sellers find this hybrid approach the best balance of cost and convenience.

5. How does Sellable compare to a traditional realtor?
Sellable charges a flat $799 MLS fee plus an optional $399 coordination fee. You keep AI‑generated pricing, marketing copy, and a streamlined closing process without paying a percentage of the sale. On a $750,000 home, that typically leaves you $40,000 more in net proceeds than a 5.5% realtor would.
