What It Costs to Sell a Home in San Diego

Most "cost to sell" articles give you one percentage and move on. That number is close to meaningless in San Diego, because the biggest components are negotiated rather than fixed, and because the 2024 industry rule changes altered who pays what. Here is the actual list, separated into what you can't control, what you negotiate, and what you choose.

Costs you can't really negotiate

These are set by statute or by long-standing local custom, and they are the smallest part of the bill.

Two San Diego specifics worth knowing. First, the City of San Diego does not add a municipal transfer tax on top of the county's — unlike Los Angeles, where a city surcharge can dwarf the county figure. Second, escrow here is customarily split between buyer and seller, which differs from parts of California where one side pays it all. Custom is not law: all of it is negotiable in the contract, it just usually isn't.

Commission, after the 2024 rule change

This is the largest line item and the one that changed most recently. Commissions have always been negotiable, and there is no standard or legal rate. What changed in 2024 is how the buyer's side gets paid.

Before, sellers customarily offered a set buyer-agent fee through the MLS, and buyers rarely saw the arrangement. That practice ended. Now:

• Buyer-agent compensation cannot be advertised on the MLS.
• Buyers generally sign a written agreement with their agent, spelling out that agent's fee, before touring homes.
• A buyer can ask the seller to cover some or all of that fee in their offer — as a negotiated concession, like asking for closing-cost help.

The practical result for you is that buyer-side compensation is now a term of the offer rather than a fixed cost of selling. In a competitive situation you may pay none of it. On a home that has been sitting, offering to cover it can widen your buyer pool. It is a strategy decision, and it should be made with the same care as the list price — not agreed to by default months in advance.

Costs you choose

Optional in theory. In practice, the sellers who skip all of them usually pay more in price reduction than they saved.

• Pre-listing inspection. A few hundred dollars, and the highest-return money in the process. It converts surprises into priced line items — the reasoning is in this piece.
• Repairs. Fix what is cheap and alarming — anything electrical, anything with visible water. Disclose and price the big items instead of fixing them.
• Cleaning, paint and landscaping. The most reliable return per dollar of anything on this list.
• Staging. Ranges from a few accessories to a full install. Matters most in vacant homes and at higher price points.
• Photography and video. Buyers shortlist from a screen before they ever tour.
• Home warranty for the buyer. A modest cost sometimes offered to smooth a deal.
• Moving and temporary housing. Easy to forget in the net-proceeds math, and rarely small.

Money that leaves escrow but isn't a "cost"

These reduce your check without being expenses, and sellers routinely conflate them with costs:

• Your mortgage payoff, including interest through the closing date and any demand or reconveyance fees.
• Prorated property taxes — you pay for the portion of the tax year you owned the home. In San Diego County, whether you owe or get credited depends on where closing falls relative to the installment dates.
• Prorated HOA dues plus any transfer or document fee the association charges.
• Any liens or judgments that have to clear before title can transfer — solar loans and PACE assessments are the ones that surprise people.

Taxes and withholding

Two separate things get confused constantly: whether you owe tax on the gain, and whether money is withheld at closing.

Capital gains and the Section 121 exclusion

Under IRC Section 121, a homeowner who owned and used the property as a principal residence for at least two of the five years before the sale can generally exclude up to $250,000 of gain — $500,000 for a married couple filing jointly. Gain beyond the exclusion is taxable, and California taxes capital gains as ordinary income, with no separate lower rate.

Your gain is not your sale price minus your purchase price. It is the sale price minus your cost basis, and basis includes qualifying improvements you have made over the years. This is exactly why keeping remodel receipts matters — for long-held San Diego homes, the difference between a documented basis and a guessed one can be substantial.

California withholding — Form 593

California requires withholding on most real estate sales over $100,000, reported on Franchise Tax Board Form 593, generally at 3 1/3% of the sale price or an alternative calculated amount. It is a prepayment against your state tax, not an additional tax — you reconcile it when you file.

Sellers whose property was a principal residence under Section 121 generally qualify for an exemption, but the form has to be completed before closing. Miss it and escrow withholds, and you wait until you file to get it back. Your escrow officer will provide the form; do not treat it as paperwork to skim.

None of this is tax advice, and it is a summary rather than a complete account. Talk to a CPA about your specific situation — particularly if the home was ever a rental, was inherited, or is held in a trust or entity.

A worked example

Take a $1,000,000 San Diego sale, to show the shape of the bill rather than to predict yours.

Notice what the table shows: the fixed statutory cost on a million-dollar sale is about a thousand dollars. Everything large is negotiated or chosen. That is why a single blanket percentage is the wrong way to think about this — and why the agent you pick and the strategy you agree on matter far more than any fee schedule.

How to spend less without netting less

• Get a written net sheet before you list. Not an estimate in conversation — a line-by-line projection at your likely sale price. Any competent agent will produce one.
• Treat buyer-side compensation as a strategy, not a default. Decide it based on your home's competition, and revisit it if the market shifts.
• Spend on inspection and presentation, not renovation. Most streets have a price ceiling that a big remodel will not break.
• Handle Form 593 before closing. Free to do correctly, expensive in cash-flow terms to get wrong.
• Find your improvement receipts. They raise your cost basis and can reduce taxable gain.
• Price correctly on day one. The most expensive thing in this entire article is a price reduction after three weeks of stale market time.

If you want the real numbers for your home rather than an illustration, I will put together a net-proceeds estimate alongside a hand-built valuation — what it should sell for, and what you would actually keep.
