Selling Property in Mexico —
Common Mistakes and How to Avoid Them

Most of the due diligence content written about Mexico real estate focuses on buying. Selling gets less attention. This is a mistake, because the exit is where a significant amount of the financial outcome is determined — and where sellers, having spent years without needing to engage deeply with Mexican real estate law, get caught off guard.

Not Planning for Capital Gains Tax

The most common and most expensive mistake sellers make is not having planned for Mexican capital gains tax from the beginning. Mexico taxes gains at sale. The notario is required by law to withhold estimated capital gains at closing. For foreign sellers who are not Mexican residents, the effective rate is often in the 25% to 35% range of net gain.

This is not a small number. On a $200,000 gain, the Mexican tax bill alone can be $50,000 to $70,000 — before any home-country obligation. Sellers who planned their returns without accounting for this end up with a materially different outcome than they projected.

What sellers can do: keep every receipt for capital improvements made during ownership, in pesos, dated at time of payment. These increase your cost basis and reduce the taxable gain. Have a cross-border accountant review your situation well before listing — not at the point of signing a purchase agreement.

Assuming the Listing Agent's Attorney Is Your Attorney

When you list a property in Cabo, the listing side may recommend an attorney to handle the closing. That attorney may be excellent. But they may also have a referral relationship with the side that brought them in — and their job is often to get the transaction closed, not to represent your interests specifically.

As a seller, you have interests that need representation: ensuring the buyer's earnest money is properly structured, ensuring that the purchase agreement does not expose you to liability after closing, ensuring that capital gains tax is calculated correctly and not over-withheld, ensuring that the title transfer is clean and the trust is properly transferred. Have your own attorney review the transaction before you sign anything.

Incomplete or Disorganized Property Documents

When a buyer's attorney begins due diligence, they will request a set of documents. If you cannot produce them quickly and cleanly, it signals risk — and buyers use that signal to negotiate price reductions or walk away.

Before you list, assemble: the current title from the Public Registry, the fideicomiso documents including the trust permit and trust agreement, proof that annual trust fees are current, the condominium regime registration, HOA incorporation documents and current financials, predial (property tax) receipts for the past five years, and receipts for capital improvements.

A seller who can hand over a complete document package on day one of due diligence closes faster and negotiates from strength. A seller who produces documents slowly and incompletely invites questions about what else is missing.

Pricing Against Developer Pre-Sales

One of the consistent pricing mistakes in the Cabo resale market is sellers benchmarking their asking price against what new developer units are selling for in the same area. Developer pre-sales are often priced optimistically, with marketing budgets behind them and a long selling timeline built into the business model.

Resale buyers are comparing your unit against what they can buy directly from a developer, with new construction warranties, fresh finishes, and a developer sales team behind it. Unless your unit offers something the new construction cannot — established rental history, better views, immediate availability, proven building management — you are not competing on equal footing. Price accordingly.

Underestimating Total Selling Costs

Sellers in Cabo frequently underestimate total transaction costs. Agent commissions in Mexico typically run 5% to 6% of the sale price. Add capital gains tax withholding, notario fees, trust transfer fees, and any outstanding HOA or predial arrears that need to be cleared at closing, and total selling costs can easily reach 10% to 15% of the sale price — more if the capital gains liability is significant.

Model your net proceeds at 12% to 15% below sale price before you have done capital gains planning. Then have the tax conversation with an accountant and understand the specific number. Going in with a rough model beats going in with no model.

Waiting Too Long to Start

Transactions in Mexico move slowly. Buyer due diligence takes time. Notario preparation takes time. Trust transfers require bank coordination. If there are any title issues, regime questions, or document gaps to resolve, add months.

If you are selling because of a life event with a timeline — retirement, a move, financial need — start the process earlier than feels necessary. A seller who needs to close by a specific date is a seller who negotiates from weakness. Start with enough runway to let the transaction happen at its own pace.
