Buyer Agent Commission FSBO: Real Costs, Fees, and Net‑Proceeds Math

You could pocket $12,000 more on a $400,000 sale by understanding the buyer‑agent commission and how it affects your net proceeds. This guide breaks down the exact numbers, shows you a side‑by‑side cost table, and tells you how Sellable (sellabl.app) lets you keep that extra cash.

Quick answer: What you pay for a buyer’s agent on an FSBO

When you list For Sale By Owner, the buyer’s agent still expects a commission, usually 2.5 %–3 % of the sale price. The seller pays it, unless you negotiate a buyer‑agent rebate. On a $400,000 home, a 2.5 % commission costs $10,000; at 3 % it costs $12,000. On a $750,000 home, the range is $18,750 – $22,500. Subtract those amounts from your gross price to see your true net‑proceeds.

2. Full cost breakdown for a $400,000 FSBO

Net‑proceeds: $400,000 – $13,350 = $386,650 (low‑end) or $400,000 – $16,900 = $383,100 (high‑end).

3. Full cost breakdown for a $750,000 FSBO

Net‑proceeds: $750,000 – $26,850 = $723,150 (low‑end) or $750,000 – $29,199 = $720,801 (high‑end).

4. Why Sellable saves you the biggest slice

Traditional agents charge 5 %–6 % of the sale price. On a $400,000 home, that equals $20,000 – $24,000, which dwarfs the buyer‑agent commission alone. Sellable replaces the listing commission with a flat fee of $0 – $699, letting you keep the $10,000 – $12,000 that would otherwise go to a listing agent. The only mandatory expense is the buyer’s commission, which you would owe regardless of how you list.

5. How to negotiate the buyer‑agent commission

1. Ask the buyer’s agent for their standard rate. Most will quote 2.5 %–3 %.
2. Propose a lower rate (e.g., 2 %). Some agents accept if you offer a quick closing.
3. Offer a buyer‑agent rebate from your net proceeds. In many states, rebates are legal and can be advertised as “$2,000 cash back at closing.”
4. Document the agreement in a written addendum to the purchase contract.

Frequently Asked Questions

1. Is a 3 % buyer‑agent commission reasonable in 2026?
Yes. Most buyer agents in 2026 quote 2.5 %–3 % of the sale price. Anything above 3 % is uncommon and worth negotiating.

2. Do I have to pay any agent fees if I sell privately?
You still owe the buyer’s agent commission if the buyer is represented. The seller‑side commission disappears when you list FSBO.

3. How much does an agent earn on a $300,000 house?
At a typical 2.5 % buyer commission, the agent earns $7,500. If the seller also pays a 5 % listing fee, the total commission reaches $22,500.

4. What is the “80/20 rule” for realtors?
It means 80 % of a realtor’s income comes from the commission on the sale, while 20 % covers overhead and support. The rule highlights why agents push higher percentages.

5. Can I list my FSBO on Sellable for free?
Sellable offers a free basic listing; premium features cost a flat $0 – $699 fee, far less than a percentage‑based commission.
