I'm an agent, so you know where I land. But the honest version of this answer involves a number that makes the case better than anything I'd say about my own value.
In July, the median San Francisco single-family home sold for 125% of its list price. A year earlier it was 110%. Understanding where that premium comes from is the whole decision.
Where the 25% actually comes from
San Francisco listing agents price below expected value on purpose. It's standard practice here and it looks strange from outside: you list at $1.6 million expecting $2 million, because a low number pulls in more buyers, and competing buyers bid each other up past what any single buyer would have offered on their own.
That strategy only works if enough buyers see the listing in the first few days. The mechanism is MLS exposure feeding every portal and every buyer's agent in the city, plus the agent-to-agent network that flags a property before it goes live.
Without that, underpricing isn't a strategy. It's just underpricing.
This is the part FSBO sellers usually miss. The commission looks like the cost, but the real question is whether you can generate competition. In a market with 1.4 months of inventory where homes close in a median of 12 days, competition is the entire game.
The math, roughly
On a $2 million sale, a typical listing-side commission runs somewhere around $50,000, negotiable and worth negotiating.
Now take the same house listed at $1.6 million. If competition takes it to $2 million, that's $400,000 above list. You don't need the full premium to justify the fee. You need about an eighth of it.
I'm not claiming every seller captures that. Some homes get one offer. But the asymmetry is what matters: the downside of hiring someone is a known, negotiable fee, and the downside of going alone is an unknown amount of money you never find out you left behind.
What you actually get for the commission
Pricing. A comparative market analysis using sales within your specific pocket of the city, not a citywide average, and a read on how far under to list without leaving money behind. Too far under kills your floor; not far enough kills the momentum.
Exposure. MLS distribution, professional photography, video and 3D tours, open houses, and outreach to agents who already have buyers looking in your neighborhood.
Negotiation. Not just price. Inspection repairs, seller credits, closing timelines, and which contingencies to push back on. In a multiple-offer situation the highest number isn't always the best offer, and knowing the difference takes practice.
Transaction management. California disclosure requirements are extensive and San Francisco adds its own layers. Errors here surface after closing, when they're expensive and you have no leverage.
The honest case for FSBO
There's one situation where it clearly makes sense: you already have a buyer. A neighbor, a family member, a tenant. The price is essentially settled and what you need is paperwork, not marketing. In that case hire a real estate attorney or a transaction coordinator and skip the commission. You're not buying exposure you don't need.
Flat-fee MLS services are the other thing worth knowing about. They'll put your listing on the MLS for a few hundred dollars, which addresses the exposure problem partially. What they don't give you is the pricing judgment, the agent relationships, or someone negotiating on your behalf when four offers land at once.
Beyond that, FSBO in this market means competing against professionally marketed listings for the same buyers, and handling inquiries, showings, disclosures, inspections, and negotiations yourself while the clock runs.
A note on cash buyers
Some sellers considering FSBO end up talking to investors who promise a fast, as-is close. They do close fast, and they buy below market. That's the trade.
In a market where homes are selling in under two weeks at 25% over asking, the speed they're offering isn't worth much. If you need to close in ten days for a specific reason, it's a real option. If you're just trying to avoid the process, you're paying a large premium for convenience.
How to decide
Hire someone if you want maximum exposure, need pricing guidance, don't have time to run the sale yourself, or want someone accountable for the paperwork.
Sell it yourself if you already have your buyer and just need the transaction handled.
If you're somewhere in between, the useful next step is finding out what your home would list for and what it might actually close at. That gap is the number your decision turns on.
Frequently asked questions
Is it cheaper to sell my house myself?
You save the listing commission. Whether you net more depends on whether you can generate the buyer competition that drives sale prices past list in this market.
Do homes sell for more with an agent?
In San Francisco the premium over list is substantial, with the median single-family home closing at 125% of asking in July. That premium comes from competition, and competition comes from exposure.
What are the risks of selling without a REALTOR®?
Mispricing, limited exposure, disclosure errors that surface after closing, and negotiating alone against an experienced agent on the other side.
Can I sell without paying any commission?
You can avoid the listing commission. Buyers often still bring their own agent whose compensation is negotiated in the deal, and you'll still pay escrow, title, and transfer costs.
Should I take a cash offer?
Compare it against what your home would bring on the open market before deciding. Investors close fast and price accordingly.
How do I find out what my home is worth?
A comparative market analysis from a local agent, which costs nothing, or a formal appraisal if your property is unusual enough that comps don't capture it.
Is FSBO common in San Francisco?
Uncommon. Most transactions here involve representation on both sides, largely because of the transaction values and the complexity of local disclosure rules.
The bottom line
The commission is visible and the lost premium isn't, which is why this decision often gets made on the wrong number. In a market this competitive, what you're buying is access to buyer competition, and that's worth considerably more than it costs.
If you already have a buyer lined up, none of that applies and you should keep your money.
