For sale and pre-construction

The best apartment isn't the one they show you. It's the one you compare.

Filter the inventory and message us from the property you're interested in. And if you're buying pre-construction, keep reading: that's where comparing unit by unit pays off most.

What the price list doesn't say

A price list is built to sell, not to inform.

We've been through dozens of developer price lists and brochures. Something is almost always missing, and that something costs money. These are real cases.

  • Availability coded by colorReserved units marked only with a shade of gray, explained in the fine print. Print the list in black and white and you'd never notice.
  • Undefined square-meter columnsA column labeled “Extra” adding meters to the total, with no document anywhere saying whether it's terrace, balcony or common area.
  • Documents that contradict each otherThe brochure offers three parking spaces; the spec sheet for the same model says two.
  • Very short price validityLists valid for ten days from the day you receive them, with nobody mentioning it during the visit.
  • Inventory that doesn't add upA page advertising “last three apartments” above a table that lists only two.
What we do for you

We turn the market's scattered inventory into a clear decision.

We're with you from end to end: from the first search to the closing at the notary. The consulting is part of the service, not an extra that gets billed separately.

01

Side-by-side across developments

We cross-check available units from several projects in the same area: real price per square meter, usable versus sellable area, storage, parking and amenities. In a single table.

02

Price-list audit

We check the document you were handed against the brochure, the spec sheet and actual availability. We tell you what's missing, what contradicts itself, and what to ask the developer.

03

Payment structure

We compare 30/20/50, 20/20/60 and 10/10/80 schemes against your cash flow, and identify projects with EDGE certification, which qualify for green mortgages at a preferential rate.

04

Choosing the unit

Within one development, two units of the same model are not worth the same. Orientation, floor, view, and whether it faces in or out will define your appreciation and your rental income.

05

Due diligence before you reserve

Who the developer is, what they've delivered before, where their permits stand, and what the contract says about delays and refunds.

06

With you through closing

Holding deposit, contract, construction progress and the deed. We confirm which projects can transfer title immediately and which only at delivery.

Fees

Our advice costs you nothing.

In pre-construction, our fee is paid by the developer out of the sales commission, which is already built into the list price. Buying with Katto does not make your apartment more expensive.

And we don't work with a single developer. If we only had one project, there would be nothing to compare.

We work with any nationality

Clients from anywhere in the world, looking in any state in Mexico. If what you want isn't in our inventory, we go find it.

Does what you find need work?

We design and remodel it with you before you move in. See design & remodeling →

Frequently asked questions

Costs, taxes and the step by step.

The questions that always come up, answered before you have to ask them.

What are the steps in a purchase?
  1. Offer. You put your proposal in writing and price and terms are negotiated.
  2. Holding deposit. An amount is paid to reserve the property and take it off the market, typically between $50,000 and $100,000 pesos. Make sure it's covered by a written agreement stating what happens if either side backs out: without that paper, a holding deposit is a verbal promise.
  3. Legal review. Before you commit further, the title is checked, along with whether the property is free of liens, and whether property tax, water and condominium fees are up to date.
  4. Promissory purchase agreement. It is signed and typically 10% of the total operation is paid, with the holding deposit counted inside that figure. The agreement sets deadlines, who pays what, and the penalties if someone defaults.
  5. Notary. One is chosen and both parties submit their documentation.
  6. Filings. The notary requests the lien-free certificate, the appraisal and the no-debt certificates, and files the preventive notice so nobody else can sell the property in the meantime.
  7. Financing, if any. The bank does its own appraisal, approves, and instructs the notary. This is the step that stretches the timeline most.
  8. Tax calculation. The notary calculates the buyer's acquisition tax and the seller's income tax, and issues the closing estimate.
  9. Signing the deed. The balance is paid and the deed is signed before the notary.
  10. Handover. Keys, and it's worth recording in writing the condition in which the property is received.
  11. Registration. The notary records the deed with the Public Registry and later gives you your certified copy. This last step happens once you already live there and usually takes weeks.

End to end, a cash purchase usually takes one to two months; with a mortgage, longer. We're with you at every step and tell you what comes next before it's due.

How much are notary costs?

There is no single nationwide rate. Notary fees are set by each state's tariff schedule and calculated in value brackets rather than as a flat percentage, so the same transaction costs differently in Monterrey than in Mérida.

As a budgeting reference, a buyer usually sets aside between 4% and 8% of the property's value for the whole closing. That covers several different items: notary fees, acquisition tax, Public Registry recording, appraisal and certificates. Worth knowing that the tax is usually the largest part of that package, not the fees.

That range is a market-practice reference, not an official figure: it moves with the state, the value of the property and whether a mortgage is involved. Before signing, the notary issues an estimate with the items broken out. We ask for it in writing and go through it with you line by line.

How much tax do I pay when buying?

It's called the Property Acquisition Tax (ISAI, or traslado de dominio) and the buyer pays it. Here's the detail that surprises people: it isn't set by the federal government or the state, it's set by each municipality. Two cities in the same state can charge different rates.

As far as we were able to confirm in September 2026, in the markets where we work:

  • Mexico City — progressive bracketed rate, roughly 1.5% to 7.6% depending on value
  • Monterrey and the rest of Nuevo León — 3%
  • Los Cabos — 3%
  • Cancún — 3%
  • Playa del Carmen — 4%
  • Tulum — 3%
  • Mérida — progressive bracketed rate; the notary confirms the exact percentage

These rates are reviewed every year and some moved recently: Playa del Carmen went from 3% to 4% in December 2025. Use them to budget, not as a final figure. The notary is who gives you the exact number for the day, and if you tell us which property it is, we'll request it for you before you put down a deposit.

When I sell my home, can I avoid income tax?

Possibly. Mexico's income tax law provides an exemption for the sale of your primary residence, in article 93. The main conditions: that it genuinely was your home and you can prove it with documents in your name at that address; that the sale is formalized before a notary; that you haven't used the exemption in the previous three years; and that the price does not exceed 700,000 UDIs.

Careful with that last one: the UDI is updated daily, so its peso equivalent changes. Don't rely on a figure you read months ago. If the price exceeds the cap, the exemption applies up to the limit and the excess is taxed.

The exemption is per person, so a married couple can have two. The notary does the calculation and withholds accordingly. Confirm it with your accountant before signing: it's one of the points where the most money is won or lost in a sale.

What is the jornada notarial and can I use it?

It's a program that discounts notary fees so that more people can get their property properly deeded. In Mexico City it has run permanently since 2017, coordinated by the Notaries' Association and the city government. Other states run their own sessions on specific dates, so if your property is outside Mexico City it has to be checked case by case. It mainly covers regularizing homes, purchases, estates and wills.

Who qualifies. The core parameters:

  • The property must be in Mexico City
  • It must be residential. Land and commercial units are excluded
  • Its cadastral value — not its market price — must fall within the program's brackets
  • Once a year per person
  • You must first obtain the beneficiary certificate from the Land Regularization Office (DGRT), before going to the notary

How much it discounts. It's tiered: the higher the cadastral value, the lower the percentage. For purchases it runs from around 60% at the lowest values down to 10% at the program's ceiling, and for estates the discounts are higher. The peso brackets are updated every year, so the current table has to be requested from the DGRT or the Notaries' Association — don't go by one you saw last year.

Two things worth knowing up front. The discount applies to the notary's fees, not to taxes or registry duties, which are paid in full. And the program's cadastral value ceiling is relatively low, so in practice it's very useful for regularizing a family home or settling an inheritance, and rarely stretches to a market purchase in the areas where we usually work. If you think your case qualifies, tell us and we'll check before you build a budget around a different expectation.

How can I reduce the income tax on my sale?

Not with tricks — with paperwork. From the sale price you subtract the acquisition cost adjusted for inflation, and you can also deduct the improvements and extensions you made, the notary costs from when you bought, the appraisal and the brokerage commissions. All of that lowers the gain the tax is calculated on, but only what you have invoiced in your own name counts. That's the reason to keep the receipts from a remodel even when they seem useless: the day you sell, they're worth real money.

Who pays what at closing?

By custom in Mexico, the buyer covers notary costs, the acquisition tax and the appraisal; the seller covers income tax on the gain and the brokerage commissions. It isn't a rigid legal rule and it can be negotiated, but it's the usual split. We put it in writing before the signing.

What should I check before putting down a deposit?

Four things, none of which takes long: that the seller is the registered owner at the Public Registry or holds power of attorney; that the property is free of liens, meaning no mortgage or seizure; that property tax, water and condominium fees are current, because debts travel with the property; and that what's built matches what's on the deed, since an unpermitted extra room can stall a mortgage. We request and review all of this before you hand over any money.

If I change my mind after the holding deposit, do I lose the money?

It depends entirely on what the agreement you signed says, which is exactly why we insist there be one. The usual practice is to spell out each scenario: if the buyer backs out they typically lose the deposit, and if the seller backs out they typically return it, sometimes doubled. It's also customary to put in writing that the money is returned if the legal review turns up a problem or if the bank declines the mortgage. Those clauses are not negotiated afterwards — they go in before you pay.
