The most tax-efficient square footage in Los Angeles isn’t on the market. It’s behind a wall you already own.
A client called last spring from a 1970s post-and-beam above Sunset Plaza. Offer in hand: $12.4 million, all cash, 21-day close. Clean deal. He wanted out.
We ran the deed math before he ran the champagne.
At that price, the transfer alone would shed north of $740,000 before a single box got packed. Not capital gains. Not the agent side. Just the cost of signing the property away. He didn’t sell. He gutted it instead: structural stone, solid-core millwork, new envelope, new systems. Two years later the house is worth more, the money never got taxed, and the asset re-based itself from the studs out.
That’s the trade this year. Here’s what matters.
Why does selling above $10.6M cost so much more than it used to?
Because Los Angeles put a cliff at the deed, and the cliff is steep.
Measure ULA, the “mansion tax” voters passed in 2022, stacks a transfer tax on top of the base documentary tax. As of the current schedule, the active thresholds and rates are: a 4% tax applicable on sales from $5,300,000 to $10,600,000, then it steps to 5.5% at $10,600,000 and above. The value thresholds and their corresponding rates are adjusted annually based on the Bureau of Labor Statistics Chained Consumer Price Index.
Two things sophisticated sellers miss.
First: it’s not marginal. The rate hits the entire consideration, not the slice above the line. Cross $10.6M by a dollar and 5.5% applies to all of it: jumping to 5.5% on sales of $10 million or more, at $55 per $1,000. That’s a cliff, not a ramp.
Second: it’s not a tax on your gain. The real property transfer tax is an excise tax on the privilege of selling a real property interest, not a tax on the property itself, and is calculated on the consideration or value of the real property interest conveyed. You pay on gross. Break even on the trade and you still write the check.
Layer the base rate underneath. Los Angeles County assesses its documentary transfer tax, and if the property is located within the City of Los Angeles, an additional $4.50 per $1,000 of valuation is assessed and collected at the time of recording. Add ULA on top and the all-in transfer load past $10.6M runs roughly 6% of the full price.
Nicknamed the mansion tax by its supporters, Measure ULA imposed a 4 percent tax on sales over $5 million and a 5.5 percent tax on sales over $10 million: one of the steepest such levies in the nation.
This is the leverage: the tax is triggered by the transfer, not by the value. Value can grow all it wants inside a property you keep. The state only reaches it when the deed moves.
What does the tax actually cost on a real deal?
Answer first: on an $11M+ trade, the transfer friction alone funds a serious renovation.
| Sale price | ULA rate | ULA tax | + Base city/county (~0.56%) | Total at the deed |
|---|---|---|---|---|
| $9,500,000 | 4% | $380,000 | ~$53,200 | ~$433,200 |
| $10,600,000 | 5.5% | $583,000 | ~$59,360 | ~$642,360 |
| $12,400,000 | 5.5% | $682,000 | ~$69,440 | ~$751,440 |
| $18,000,000 | 5.5% | $990,000 | ~$100,800 | ~$1,008,000 |
Base rate approximated from county + City of LA documentary transfer tax. ULA applies to full consideration above threshold.
Look at the $10.6M line. That’s $642,000 to exit: money that buys nothing, builds nothing, and doesn’t follow you to the next house. It’s pure friction.
Now flip it. For a high-end remodel with luxury materials, custom designs, and structural changes like a new-construction addition, you can expect to budget $350 to $600+ per square foot. At $500 psf, $642,000 buys roughly 1,280 square feet of gut-grade renovation: a full kitchen, two baths, and a re-clad envelope on most Westside floor plans.
Same dollars. One version evaporates at the recorder’s office. The other stays in the walls.
Renovate-to-hold vs. sell-and-retrigger: which one actually wins?
Renovate-to-hold, when the asset has runway. Here’s the logic.
Sell-and-retrigger means you pay the 5.5% to leave, then you’re a buyer in the same market: competing for inventory that’s thinner precisely because of this tax. UCLA research estimates the tax has significantly reduced high-value transactions, with the odds of a property selling above the $5 million threshold falling by as much as 55%. Fewer sellers list. Fewer trophies trade. You paid to leave a market that now has less for you to buy.
Renovate-to-hold does three things at once:
- Defers the transfer tax indefinitely. No deed, no ULA. The 5.5% you didn’t pay is capital that keeps working.
- Adds to cost basis. Material-grade capital improvements raise your basis, which shrinks the taxable gain whenever you do eventually sell. The renovation dollars aren’t lost. They’re stored, and they reduce a future federal bill.
- Re-bases the physical asset. Structural stone, solid millwork, a new envelope and new systems don’t read as decoration. They read as a younger building. That’s the part the appraisal rewards.
The capex compounds untaxed because it’s sheltered inside an asset nobody’s transferring. Appreciation on a held property is unrealized and untouched by ULA. You’re not dodging the tax. You’re declining to trigger it.
Which renovations count as re-basing, and which are just vanity?
The tax logic only works if the capital is durable. Spend into the bones, not the surface.
Re-bases the asset (defensible on resale):
– Structural stone: solid slab, full-height book-matched runs, real masonry. It reads permanent because it is. It doesn’t date on a five-year cycle.
– Solid millwork: quarter-sawn, joined, integrated. Not applied panels. A buyer’s inspector can tell the difference, and so can the appraiser.
– Envelope: roof, cladding, waterproofing, glazing. Invisible until it fails, and catastrophic when it does. This is where insurers and lenders actually look.
– Systems: electrical, plumbing, HVAC, seismic. Unsexy. The first thing a $15M buyer’s team scrutinizes. New systems clear diligence fast and quiet.
Vanity (won’t hold the number):
– Trend finishes, fashion-color cabinetry, statement fixtures that read as this-season.
– Anything a next buyer plans to demo. If it’s coming out, it never went into the basis in any way that helps you.
The test: Will the next serious buyer keep it, or price around it? Craft that survives the next transaction is capital. Craft that doesn’t is decoration wearing a capital costume.
This is the discipline. Reverence for the material. None for the receipt.
Does the math change after June 30, 2026?
Yes: the cliff moves up, but the mechanics don’t.
Effective for transactions closing after June 30, 2026, the new ULA thresholds will be $5,400,000 and $10,900,000. Transactions greater than $5,400,000 but less than $10,900,000 will be assessed a 4% tax, and transactions of $10,900,000 or greater will be assessed a 5.5% tax.
For a seller sitting just under a threshold, timing is a lever. But don’t let a $300,000 threshold shift drive a nine-figure hold decision. The structural point survives every annual adjustment: the tax fires on transfer, and the highest-return capital in this market is often the capital that never crosses the deed.
Note the political layer, too. In 2022, Los Angeles voters approved Measure ULA, a transfer tax on the sale of high-value properties inside the city limits, and the revenue funds affordable housing and tenant protections, which makes it durable and politically defended. Plan around it as permanent. If it softens, that’s upside, not the base case.
The TKG read
Objective: Preserve capital that would otherwise vaporize at the deed, and convert transfer friction into durable, basis-building value.
Intel: ULA hits the full sale price, 4% from $5.3M, 5.5% at $10.6M, as an excise on the transfer, not the gain. Thresholds step to $5.4M / $10.9M after June 30, 2026. High-value transaction volume is down materially; the exit market is thinner than the entry math suggests.
Risk: Renovate-to-hold only pencils if the asset has runway and the capital goes into the bones. Trend-driven capex doesn’t re-base: it depreciates. Over-improving past the block ceiling strands money. And a hold ties up liquidity you may need elsewhere.
Play: Model both paths side by side, net-to-you on a sale today vs. re-based value on a two-year hold. Direct capex to structure, stone, millwork, envelope, systems. Document every dollar to basis. Time any forced sale against the threshold calendar.
