Hardly any purchase in Tulum goes wrong because of a single big decision. It goes wrong because of a chain of small decisions, made in haste and from afar, that add up until there’s no cheap fix. We see them repeat with buyers from the United States, Canada and Europe, and almost always they’re the same five.
We back this with our own inventory numbers: 46 of the 79 properties we have for sale are in Tulum, so we see this market every day.
Mistake 1 · Choosing the agent for the ad, not for the paperwork
A foreigner’s first contact with Tulum is usually a social media ad or a search result for “real estate agency in Tulum” or “real estate agent in Tulum.” And that’s where almost everything gets decided, because the agent filters which properties you see, which documents you’re shown, and which notary you’re sent to.
What to ask for before viewing a single home:
- Legal name of the company or person, with RFC, and a physical address you can visit.
- Written brokerage agreement stating who pays the commission and how much. In Mexico it’s customary for the seller to pay it, typically in the 4% to 7% range of the price, but it’s negotiated and should be in writing.
- References from foreign buyers who have already closed, not just reviews.
A serious agent won’t be offended by this. The one who is has already told you what you needed to know.
Mistake 2 · Comparing prices in two currencies as if they were one
In Tulum, listings are in pesos and in dollars, sometimes within the same building. In our inventory, of the 46 Tulum properties, 13 are priced in pesos and 33 in dollars. Nearly one in three.
The typical mistake is to eyeball a sheet showing “2.450.000” against one showing “160.000,” or to convert at the exchange rate on the day you saw the ad, not the day you pay. In a purchase settled over several months—reservation deposit, down payment, construction payments, deed—the exchange-rate gap between the first and last payment can move the real price by several points, for or against you.
Three simple rules:
- Convert everything into a single currency before making your short list.
- Ask in which currency the contract is signed and in which it is paid. They’re not always the same.
- Agree in writing on the exchange rate if the contract is in pesos and you pay in dollars, or vice versa.
Mistake 3 · Believing the brochure’s return
It’s the costliest and most common mistake. The developer presents a projection of occupancy, nightly rate, and annual return, and the buyer treats it as fact.
One number says a lot about how we handle this: of the 46 Tulum listings we publish, only one states an annual income, and none a return percentage. That’s not an oversight. A return you can’t verify shouldn’t be on a listing.
If you’re shown one, ask:
- Is the occupancy from a building that’s already operating, or a projection?
- Is the rate a peak-season figure or the full-year average?
- Is the figure gross, or does it already deduct the manager’s fee, the platform, cleaning, maintenance, property tax, and other taxes?
The gap between gross and net in vacation rentals is large. Ask for net figures, and if you don’t get them, run the numbers with half the optimism.
Mistake 4 · Forgetting what it costs to get it rental-ready
The list price is for the property, not for a guest-ready property. In our Tulum inventory, 36 of the 46 are sold unfurnished, and only 6 furnished and 4 equipped. That’s the market norm, not an exception.
If the plan is to rent, add to your budget from the start:
- Full furniture and equipment: beds, living room, kitchen, linens, AC if it’s not included, decor that photographs well. For a one- or two-bedroom unit, as a guideline, between 10.000 y 30.000 dólares depending on the level.
- Professional photos and listing on platforms.
- The first months of operations, which almost never start with mature-year occupancy.
A buyer who stretches to the purchase price and can’t furnish takes months to start renting, and those months also count in the return.
Mistake 5 · Paying the reservation deposit before seeing the paperwork
The excitement of finding “the unit” leads to reserving it that same day, via wire, before seeing a single document. And the reservation deposit, per the contract, may be non‑refundable.
Before sending a single peso, ask for at least:
- Recorded deed in the Public Registry of Property, or, if it’s a presale, the land title in the developer’s name.
- Certificate of no liens.
- Permits: building permit and land-use/zoning, if it’s new construction.
- The reservation agreement in writing, with the conditions for a refund.
And a rule with no exceptions: the money goes to the company’s account, the notary’s account, or an escrow—never to anyone’s personal account.
Behind this mistake there’s usually another: leaving the bank trust and the power of attorney for the end. Tulum is in the restricted zone, so a foreigner buys through a bank trust, and if you won’t travel you’ll need an apostilled power of attorney. Both processes take weeks.

What the five have in common
None of these mistakes is about the market. They have nothing to do with whether Tulum is up or down, or whether La Veleta —the area with the most properties in our inventory, eleven— is better than Aldea Zamá. They’re mistakes of sequence: first comes what’s exciting —the view, the pool, the render— and what protects the money gets left for later.
The buyer who flips that order, who starts with the agent, the currency, the net numbers, the full budget, and the paperwork, buys calmly what the other buys in a rush. And almost always pays less.
If you already have a property in mind
Send us the listing they showed you, whether it’s ours or not. We’ll tell you which documents are missing, whether the return they presented is real or projected, and how much you should set aside beyond the price. Write to us: it’s the conversation that saves a buyer the most money, and it costs you nothing.
