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.
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.
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.
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.
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.
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.
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.
Who the developer is, what they've delivered before, where their permits stand, and what the contract says about delays and refunds.
Holding deposit, contract, construction progress and the deed. We confirm which projects can transfer title immediately and which only at delivery.
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.
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.
We design and remodel it with you before you move in. See design & remodeling →
Pricing from real comparables, document review before we list, and someone with you through to the signing at the notary. Nothing paid up front.
The questions that always come up, answered before you have to ask them.
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.
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.
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:
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.
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.
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:
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.
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.
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.
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.
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.
The percentages in this section are for reference and were confirmed in September 2026 against municipal revenue laws. Rates are set by each municipality and reviewed annually. The definitive calculation of taxes and costs is made by the notary for your particular transaction, and tax decisions are best taken with your accountant. Katto does not provide notarial, accounting or legal services.
