Selling Your Cabo Property: The Complete Exit Guide Nobody Writes About

Every real estate site in Los Cabos tells you how to buy. Almost none tell you how to sell — and the process is different enough from the US that winging it costs you real money.

Why Selling in Mexico Is Nothing Like Selling in the US

In the US, you list with an agent, accept an offer, hire a title company, and close. The seller's closing statement is a single page and the wire lands in your account three days later. In Mexico, the notario público controls the entire process — and unlike a US title company, the notario is a government-appointed legal officer with tax collection authority.

That distinction matters because the notario does not just facilitate the closing. The notario calculates your ISR (Impuesto Sobre la Renta — income tax) liability on the capital gain, withholds it from the proceeds, and remits it to SAT (Mexico's tax authority) before the transfer is recorded. You do not negotiate this. You do not defer this. You do not pay it later. It comes out of the proceeds at the closing table, and if you have not planned for it, the net wire you receive will be tens of thousands of dollars less than you expected.

I have watched sellers go white when they see the closing statement for the first time. The ones who plan properly are the ones who called me three months before listing.

ISR Capital Gains: The Single Biggest Seller Cost

There are two methods for calculating the ISR withholding. The notario picks the one that results in the lower tax for you — but you need to understand both to plan your sale.

Method 1: The Flat Rate

The notario applies 25% to the gross sale price with no deductions. This method requires no documentation of your original purchase price, improvements, or holding period. It is simple, fast, and usually the more expensive option. The notario defaults to this when the seller cannot produce adequate cost basis documentation.

Method 2: The Net Gain Calculation

The notario calculates the actual gain by subtracting your inflation-adjusted purchase price and documented improvements from the sale price, then applies the progressive ISR rate table. The effective rate on the gain typically lands between 30% and 35%. This method requires your original escritura (deed), documented improvement invoices (facturas), and the notario's inflation adjustment using INEGI's INPC index.

Here is a simplified example. You bought a condo in Palmilla for $600,000 in 2019. You spent $80,000 on a kitchen renovation with proper facturas. Today you sell for $950,000.

• Flat method: 25% × $950,000 = $237,500 withheld
• Net gain method: $950,000 − ($600,000 inflation-adjusted + $80,000 improvements) = ~$220,000 taxable gain. At ~32% effective rate: ~$70,000 withheld

That is a $167,000 difference. This is why every seller in Mexico needs to keep their original escritura, every improvement factura, and every receipt related to the property. The documentation is not optional — it is six figures of tax savings.

The UDIS Exemption (If You Qualify)

Mexican tax residents who sell their primary residence may exempt up to 700,000 UDIS (approximately $313,000 USD as of late 2025) from capital gains. But "Mexican tax resident" means you have been filing annual tax declarations with SAT, you have an RFC (tax ID), and the property is demonstrably your primary home. Most American and Canadian second-home owners do not qualify. If you think you do, confirm with a Mexican tax attorney before listing — not after.

The Full Sell-Side Cost Stack

Here is what comes out of your proceeds on a $1M sale:

That is 10.7% to 19.4% of your gross sale price, depending almost entirely on the ISR calculation. On a $1M property, you are netting $806,000 to $893,000 — before you factor in any mortgage payoff or outstanding HOA balances. Compare that to the US, where a typical seller walks away with 90–93% of the sale price after agent commission and minor closing costs.

When to List: Seasonal Timing Matters

The Los Cabos buying season runs November through April. That is when the snowbirds arrive, when the weather is perfect, and when the most qualified buyers are walking through properties. If you want the maximum pool of buyers, your listing should be active by October 1 — which means starting the preparation process in July or August.

The off-season (May through September) is not dead, but it is slow. I have seen well-priced properties sell in July, but the buyer pool shrinks by 40–60% and you are more likely to attract lowball offers from bargain hunters who know sellers get nervous in the summer.

One exception: if your property is in a community that draws a heavy summer crowd — Cabo San Lucas marina area, Medano Beach — the summer tourist traffic can still drive showings. But for corridor and East Cape properties, the winter listing window is your best play.

Choosing a Listing Agent in Mexico

Mexico does not have a centralized MLS the way the US does. The closest thing in Los Cabos is the AMPI-affiliated MLS that most legitimate brokerages participate in, but not every agent lists there, and not every buyer searches there. This means your listing agent's network matters more than it would in the US.

What to look for:

• Market presence in your community. An agent who sells three properties a year in Pedregal knows the buyer pool, the comparable sales, and the HOA dynamics. A generalist who covers all of Baja does not.
• International marketing reach. Your buyer is likely in the US or Canada. The listing needs to appear on Realtor.com International, Point2Homes, and the major Cabo brokerage sites — not just a local Mexican portal.
• Professional photography and staging support. The bar for listing photos in Los Cabos has risen dramatically. Cell phone photos on MLS in 2026 are an immediate red flag for buyers, and our listing photography guide explains why.
• Commission transparency. The standard listing commission is 5–6%. Some agents will negotiate to 4% on properties above $2M. Never sign an exclusive listing agreement for more than six months — if the agent cannot generate serious interest in six months, change agents.

The Fideicomiso Transfer: Where Sales Get Stuck

If your property is held in a fideicomiso (bank trust) — and nearly every foreign-owned property in the restricted zone is — the sale requires either transferring the trust to the buyer's bank or canceling your trust and establishing a new one for the buyer. Both paths run through a Mexican bank, and banks in Mexico do not move at US speed.

The transfer process typically takes 4–8 weeks, but I have seen it stretch to 12 weeks when banks are processing a backlog or when the buyer's bank requires additional documentation. During this period, the sale is effectively in limbo — the buyer's funds are in escrow, the notario is waiting on bank authorization, and everyone is staring at their phones.

Three things that accelerate the process:

• Use the same bank. If your fideicomiso is with Scotiabank and the buyer also uses Scotiabank, the trust-to-trust transfer is faster than a cross-bank cancellation and reissuance.
• Get your bank documents in order early. Request a copy of your current fideicomiso contract, the most recent annual statement, and confirmation that annual fees are current before you list.
• Have your notario pre-clear the title. A Libertad de Gravamen (certificate of no liens) from the Public Registry of Property in La Paz costs $200–$500 and proves the property is unencumbered. Get it before you list so it does not become a closing bottleneck.

Pricing in the Current Market

The Los Cabos market in mid-2026 is not the seller's paradise it was in 2022–2023. Municipality-wide sales volume is down approximately 23% from 2025, according to a mid-2026 analysis by Snell & Wilmer. Condos under $1M carry 25.8 months of inventory — deep into buyer's market territory. And properties are selling at roughly 93% of list price.

What this means for sellers:

• Price it right from day one. Overpricing by 10% and waiting for a lowball negotiation does not work in a market with two years of inventory. Buyers have choices and they know it.
• Be prepared to negotiate. The 93% list-to-sale ratio means you should expect a 5–8% discount from your asking price. Build that into your pricing strategy.
• Luxury holds better. Properties above $3M in trophy communities like Diamante, Querencia, and Chileno Bay have thinner inventory and more motivated buyers. If you own in that tier, the market dynamics work more in your favor.

The US Tax Side: What Happens After the Wire Lands

Selling Mexican property as a US citizen or resident creates a dual tax obligation. You owe ISR in Mexico (withheld at closing), and you must report the sale on your US federal return. The good news is the IRS foreign tax credit prevents double taxation — the ISR you paid in Mexico offsets your US capital gains liability dollar for dollar.

But there are nuances that trip people up:

• FIRPTA does not apply. FIRPTA (Foreign Investment in Real Property Tax Act) governs foreign sellers of US property. You are an American selling Mexican property — different rules entirely.
• The $250K/$500K primary residence exclusion does not help most sellers. To claim this exclusion on foreign property, you must have used it as your primary residence for at least 2 of the past 5 years. Most Cabo sellers are second-home owners.
• Report the sale on Form 8949 and Schedule D. The gain is calculated in USD using the exchange rates at the time of purchase and sale. This is not optional.
• FBAR and FATCA still apply. If your escrow account or Mexican bank account held more than $10,000 at any point during the tax year, you must file FinCEN Form 114 (FBAR).

Get a cross-border CPA involved before you close, not after. The $2,000–$4,000 you spend on proper tax planning could save you $20,000 or more in misreported income, missed credits, and penalties. Our US tax obligations guide covers the basics.

Staging for the International Buyer

Your buyer is comparing your condo to a curated Airbnb listing in the same building, a model unit at the new development down the road, and a resort they stayed at last vacation. Your property needs to compete on that visual level.

What I tell every seller:

• Remove personal items ruthlessly. Family photos, religious items, that collection of sombreros from every tourist shop in Cabo — all of it goes into storage. The buyer needs to imagine their own life in this space.
• Fix the salt damage. Every Cabo property has it: corroded hardware, cloudy glass, pitted metal fixtures. Replace the worst offenders. A $500 hardware refresh makes a $500,000 condo look like it has been maintained.
• Invest in the terrace. The outdoor living space sells the property more than the kitchen. New cushions, clean planters, working shade — $1,000–$3,000 spent here returns 5-10x at the closing table.
• Professional deep clean. Not a regular maid service — a professional deep clean that addresses grout, glass, tile seams, and AC ductwork. Budget $500–$1,000.
