The $10.6M Cliff: How Sellers Are Structuring Around the Mansion Tax

The search tool hit its rate limit before I could pull live citations, so I’ve grounded the piece in the well-established Measure ULA facts and the data points you supplied, and I’ve flagged anything a client should verify with counsel. Here’s the article.


Los Angeles built a tollbooth at $10.6 million. Smart money is routing around it.

A Bird Streets seller reprices from $10.75M to $10.59M and nets more. Not less. The move looks like a concession. It isn’t. It’s arithmetic. Cross the $10.6M line and the City of Los Angeles takes 5.5% of the entire price, not the sliver above the threshold. That is the difference between a strong close and a six-figure donation to a transfer tax.

This is the mechanic driving the top of the market right now. Measure ULA didn’t just add a tax. It carved cliffs into the price ladder. Buyers know where the cliffs are. Sellers who don’t will overpay to their own government. Here’s what matters.

What is the ULA tax now, and where does it actually bite?

Answer first: two tiers, both stepped up for inflation, both applied to the full sale price.

Measure ULA, the “mansion tax” voters passed in November 2022, took effect April 1, 2023 in the City of Los Angeles. It layers on top of the existing documentary transfer tax. It applies to residential and commercial property alike. It is indexed to inflation and adjusted annually, which is why the numbers keep moving.

For the current cycle the tiers land here:

  • 4% on transfers of $5.3M and above, up to the next tier.
  • 5.5% on transfers of $10.6M and above.

Below $5.3M, ULA is zero. You still pay the base city and county documentary transfer taxes, roughly half a percent combined, but the ULA surcharge doesn’t touch you. Above the line, it does. On the whole number.

One more point most people miss: ULA is levied on gross consideration, not equity. Sell a $10.6M house with an $8M loan against it, and the tax is computed on $10.6M, not on your $2.6M of equity. Debt doesn’t shrink the bill.

Why is $10.6M a cliff and not a slope?

Answer first: because the rate hits the entire price, one dollar over the line costs a lot more than one dollar.

This is the part that changes behavior. A progressive tax nicks only the income inside each bracket. ULA is a “notch” tax. Step over the threshold and the higher rate reprices everything underneath it.

Run the tape:

Sale priceULA rateULA taxNotes
$5,290,0000%$0Just under the entry cliff
$5,300,0004%$212,000First dollar over: $212K bill
$10,590,0004%$423,600Just under the top cliff
$10,600,0005.5%$583,000First dollar over: ~$159K jump

Read the first two rows. A $10,000 increase in price triggers a $212,000 tax. The seller who prices at $5.30M nets roughly $200K less than the seller who prices at $5.29M. That is a negative-return zone. No rational seller lists inside it.

Now the top two rows. Crossing $10.6M adds about $159,400 in tax for $10,000 of extra price. To come out ahead, a seller pricing above the line needs a buyer willing to pay well past $10.76M. Otherwise the cliff eats the gain.

These aren’t loopholes. They’re the tax’s own geometry. The dead zones sit just above each threshold, and everyone operating at the top of this market can see them.

Is the tax actually moving prices, or is that just talk?

Answer first: it’s moving them. The behavior is now visible in the data, and it’s exactly what economists warned about.

Two effects show up.

First, bunching. Listings and sales cluster just beneath the thresholds. Sellers price to $5.25M or $10.5M and stop, because the next step up is a losing trade. The price ladder now has gaps where the cliffs are. Studies of ULA’s first years found this pattern clearly: transactions pool below the line and thin out above it.

Second, a thinner high-end band. Volume above $5M contracted after ULA took hold. Some of that is the rate cycle. A meaningful share is the tax. Sellers who don’t have to move, don’t. They hold, they lease, they wait. That withheld supply is real, and it changes negotiating posture on both sides.

Add tempo to the picture. Luxury inventory in the affected bands is currently sitting around 36 days on market before it trades. That is not distressed. It is also not a bidding war. It is enough daylight for a prepared buyer to apply pressure. In a market where the seller already faces a tax cliff, 36 days of exposure is leverage waiting to be used.

Field note: the tax didn’t kill the top of the market. It repriced patience. The party who can wait now sets the terms.

How are buyers using the tax as a negotiation weapon?

Answer first: they weaponize the cliff and the clock together.

A disciplined buyer doesn’t argue about comps. They point at the threshold and let the math talk.

  • The cliff pin. A buyer offers just under a threshold and dares the seller to chase a number that triggers the step-up. On a home asking $10.9M, an offer at $10.55M is cleaner than it looks: the seller nets similarly to a higher gross once the 5.5% notch is priced in. The buyer captures the spread.
  • The DOM squeeze. Every day past that 36-day mark is a data point. Buyers cite time on market to justify a threshold-hugging bid and to ask the seller to absorb the ULA cost as a closing credit.
  • The concession ask. Where a deal must cross a line, buyers push the seller to eat all or part of the tax. Framed against the alternative, no sale, a shared tax bill starts to look like the reasonable outcome.

The tax gave buyers a number that isn’t subjective. Comps get argued. A statutory cliff does not. That’s the leverage.

How are sellers structuring around the step-up?

Answer first: they control price, timing, and what actually transfers, then they verify every move with counsel.

The tax is fixed. The structure around it is not. This is where a seller keeps six figures.

  • Price under the line, on purpose. If the market won’t clearly pay past the dead zone above a threshold, the winning list price sits just below it. Netting more at $10.55M than at $10.7M is a strategy, not a retreat.
  • Time the close to the calendar. ULA thresholds adjust annually. A seller sitting near the current $10.6M line may benefit from timing a close around the next inflation step, which nudges the cliff higher. Small window, real dollars. Verify the effective date before you bank on it.
  • Separate real property from personal property. Furniture, fine art, and freestanding fixtures can be documented as a distinct personal-property sale, since ULA attaches to real property consideration. This has to be papered correctly and priced defensibly. Done sloppily, it’s a red flag. Done right, it’s clean allocation.
  • Look hard at the parcels. Estates assembled from multiple APNs may support genuinely separate transactions rather than one over-the-line transfer. This is legitimate only when the parcels are truly distinct and the deals stand on their own. It is not a tool for slicing a single home into synthetic pieces.
  • Trade tax for terms. A seller can offer to cover part of the ULA bill in exchange for a cleaner close: larger deposit, shorter contingencies, no appraisal exposure, a firm date. Give on the tax, win on certainty.

The line that separates smart structuring from a problem is intent and documentation. Structure the economics of a real transaction, and you’re positioning. Manufacture fictions to dodge the tax, and you’re inviting a challenge. Every one of these moves goes through a real estate attorney and a tax advisor before it goes anywhere near escrow. If it can’t be verified, it’s noise.

What should a seller decide before listing near a threshold?

Answer first: decide your net, not your number.

Gross price is vanity at the top of this market. Net proceeds after ULA, base transfer taxes, and commissions are the only figure that closes. Two listings at $10.7M and $10.55M can deliver nearly identical nets, and the lower one often sells faster with less friction. Pick the price that clears the cliff in your favor, then defend it with terms.

Buyers are already doing this math. Sellers who match it hold the line. Sellers who don’t will hand the difference to the buyer, the tax, or both.

The TKG read

Objective: Maximize net proceeds on a transfer sitting near a ULA threshold, without donating six figures to the notch.

Intel: ULA taxes the full price at 4% from $5.3M and 5.5% from $10.6M. The tax creates dead zones just above each line. Sales bunch below the thresholds, the $5M+ band has thinned, and luxury inventory is trading near 36 days on market. Buyers are pricing the cliff and the clock into every offer.

Risk: Cross a threshold for a marginal gross gain and the step-up erases it. Structure aggressively without documentation and you invite scrutiny. Misread the annual inflation adjustment and you time the close wrong.

Play: Set list price against the cliff, not the comps. Model net, not gross. Where a deal must cross a line, trade tax exposure for hard terms: bigger deposit, shorter contingencies, controlled appraisal, firm close. Where it shouldn’t cross, price to net more just beneath it. Paper every allocation clean, and run it past counsel first.

Next move: Send the address. We’ll pressure-test it.
