San Miguel de Allende for the European Investor

European buyers arrive at San Miguel de Allende with a thesis rather than a shortlist. A UNESCO-protected colonial city, unable to expand its core, in an early phase of international recognition, is the setup that repriced parts of southern Europe over the last fifteen years. The Lisbon comparison gets made explicitly, often in the first email.

The supply-constraint argument is real and is the strongest structural case anyone can make for this market. It is also narrower than it sounds, it does not do what buyers assume it does to prices, and the analogy carrying it breaks in three places.

The heritage-equity thesis, stated precisely

The constraint is not one instrument but three, covering different ground.

The inscribed core is under half a square kilometre. That is the honest reason Centro cannot expand: not designation as such, but a 1982 federal permitting requirement over 68 blocks and a catalogue of 229 named buildings whose ownership changes what renovation is permitted. The water constraint is the one almost nobody raises and it binds harder. The deficit widened from 59.32 million cubic metres a year in CONAGUA’s 2015 determination to 61.98 million in 2024, and vedas on well-drilling date to 1958 and 1964, so new water rights must be bought from existing holders rather than granted. For a buyer whose thesis is that supply cannot grow, that is better evidence than the UNESCO plaque.

What supply constraint does not do

It does not guarantee prices rise. The same market that carries all three constraints was, in the most recent published data, soft.

Active listings rose from 593 in May 2025 to 860 in May 2026, an increase of 45 per cent, before falling to 745 in June. Average months of inventory over the first five months of 2026 reached 29.6, against 17.6 a year earlier, in a market whose own brokers call 15 to 18 months normal. The average resale sale price fell from USD 650,462 in 2024 to USD 568,829 in 2025, a decline of USD 81,633, while unit volume rose 24.68 per cent and dollar volume only 9.03 per cent. Sales above USD 2 million fell from 19 to 12.

Two cautions. Those figures come from one brokerage reporting on its own MLS view, and no registry, association or government index publishes closed-transaction statistics for San Miguel de Allende, so nobody can audit them. And the 2025 price decline is substantially a mix effect: removing a few large transactions moves an average built on that few sales.

The official alternative does not help. Guanajuato’s house price appreciation was 8.44 per cent in Q1 2026, marginally below the national 8.74, but that index is built from mortgage-linked appraisals and excludes cash foreign purchases, which is essentially the whole market you would be entering.

The Lisbon comparison, and where it breaks

We publish no Lisbon figures. None are in our research, and we will not source a comparison after the fact to make a thesis land. Where the two situations differ is a matter of law and infrastructure rather than data.

EU membership. Portugal’s repricing happened inside a single market with freedom of movement. Mexico is not that. A European owning in San Miguel de Allende is a foreign national under Article 27 of the Constitution, buying under an agreement, the Calvo clause, to be considered a national as to that property and not to invoke their government’s protection over it. The penalty for breach, as written, is forfeiture to the Nation.

Residency-by-investment demand. There is no Mexican golden visa. Property ownership is a standalone route to temporary residency, but only above 91,710 days of UMA, which is MXN 10,758,500.10 at the 2026 UMA of MXN 117.31 per day, and most European purchases here will not clear that bar. Temporary residency authorises no more than four years, and Article 54 of the Ley de Migracion contains no wealth or property route to permanent residency at all. The Article 57 points system remains inoperative for want of its enabling agreement. One of the demand engines behind the analogy is simply absent.

Connectivity. San Miguel de Allende has no commercial airport. The nearest is Bajio (BJX) at 3.31 million passengers in 2025, up 4.3 per cent, with Queretaro (QRO) a second option at similar driving distance, both roughly an hour and a half away by road, though we could not verify the precise drive distances. For scale, Guadalajara handled 18.77 million passengers in 2025 and Cancun 29.47 million. We hold no route list for either airport. What is certain is structural: there is no direct European route to San Miguel de Allende, because there is nowhere in San Miguel de Allende for it to land.

The demographic half of the analogy does hold. The seven census tracts inside the UNESCO polygon held 1,803 foreign residents, 42 per cent of the municipality’s foreign-born population of 4,312, and foreigners were 8 per cent of those tracts’ 22,405 residents. Whether that is the start of a repricing or the end of one, no dataset can tell you.

The currency chain

You are exposed to three currencies and only one is usually discussed. Peer-reviewed work on San Miguel de Allende finds prices are quoted predominantly in dollars rather than pesos, so the asset behaves as a dollar asset while your capital is in euros and your costs are in pesos.

On the peso leg, the sourced record is this. Spot USD/MXN was approximately 17.46 on 23 July 2026 on the European Central Bank reference, inside a six-month band from 17.1061 on 23 February to 18.1490 on 30 March, averaging 17.4452. The peso closed 2025 near 18.00 after appreciating close to 14 per cent that year on one account and nearly 16 on another, and we publish both because the sources disagree. Banxico’s policy rate stood at 7.0 per cent against the Federal Reserve’s 3.75, and that 3.25 point carry is the main support under the strong peso. Consensus forecasts for end-2026 cluster at 18.75 to 19.00.

A measurement trap catches careful people here. Spot rates and annual averages are different measures and they moved in different directions: the IRS yearly average was 18.330 pesos per dollar for 2024 and 19.212 for 2025, so the peso averaged weaker in 2025 than in 2024 even as the spot rate strengthened sharply through the year. Anyone using one to explain the other is confusing you.

The effect is concrete. A USD 3,000 monthly transfer that once converted to 60,000 pesos yielded about 51,000 in early 2026, roughly a 15 per cent loss of local purchasing power, landing on your peso costs rather than your headline price. We publish no euro rate against either currency, because our research does not contain one, and inventing one would defeat the point of this publication.

Buying and holding from another continent

Taking title

San Miguel de Allende sits in the municipality of Allende, Guanajuato, which INEGI named in the Diario Oficial de la Federacion on 21 May 1997 in the first list of municipalities located entirely outside the restricted zone. That is settled: you take direct fee-simple title in your own name, on an ordinary deed, with no fideicomiso and no bank trustee. Article 27 fraction I has not been amended since 20 January 1960, nor the Foreign Investment Law articles implementing it since 24 December 1996, so claims that the rules are changing are wrong.

Nationals of countries with which Mexico maintains diplomatic relations, which covers EU member states, file only the convenio de renuncia, at a 2026 statutory fee of MXN 5,252.02, payable rounded to MXN 5,250.00. Timing is where practice and statute diverge, and we publish all three figures rather than the friendliest: the Foreign Investment Law deems the permit granted if no denial is published within five business days for a municipality wholly outside the zone; the Secretaria de Relaciones Exteriores’ own page states approximately 20 business days; San Miguel brokers report three to six weeks. We could not source a reconciliation, so the conflict stands.

The deed must be an escritura publica under Article 1815 of the Guanajuato Civil Code, and under Article 1816 a sale produces no effect against third parties until registered. Registration, not signature, is when your title becomes secure.

What acquisition actually costs

Annual predial is charged on cadastral value, not market value, at marginal rates from 0.234 to 0.354 per cent on urban built property, 0.207 suburban and 0.18 rustic, with a MXN 349.48 minimum. Unbuilt land is penalised at 0.438 to 0.705 per cent, and that table also catches any property with less than 5 per cent of its area built on, a real trap for a large lot with a small casita. Paying the full year in January earns 15 per cent off and February 10 per cent. The 2026 statute grants nothing else, despite claims online.

Running it remotely

Letting the property draws in three levels of government. San Miguel de Allende charges MXN 45,000 per fiscal year for the lodging land-use permit and MXN 11,248.64 once to authorise the change of use. Guanajuato levies a 4 per cent lodging tax, and while platforms are named as withholding agents, host relief applies only where the platform actually remits, which the state has publicly disputed. Federally, a furnished letting loses the residential IVA exemption and is taxable at 16 per cent irrespective of lease length, by statute rather than as an enforcement position.

The revenue side does not obviously carry that stack. Across the twelve months to June 2026 the market recorded 29.9 per cent occupancy, a USD 210 average daily rate, USD 64 RevPAR and mean annual revenue of USD 17,033 across 2,285 active listings. The median listing grossed USD 1,096 a month, roughly USD 13,150 a year, the top decile USD 5,242 a month or more and the bottom quartile USD 446. Rival vendors put occupancy at 38, 41 and 44 per cent against that 29.9, so use the range. Management runs 20 per cent of gross at one named local operator, 20 to 30 quoted more loosely, 8 to 12 for long lets. We publish no yield figure: none exists, and deriving one would mean dividing revenue from all active listings by a price from a different property universe.

The exit

This is where the longest hold periods bite. A non-resident seller pays 25 per cent of gross proceeds with no deductions whatsoever, or may elect the 35 per cent top rate on the computed gain. The election beats the gross method whenever the gain is below roughly 71 per cent of the sale price, and no Mexican representative is needed to make it when the sale is by public deed, which corrects a great deal of published guidance. The notario computes and remits the tax under personal responsibility, hence the conservatism about deductions.

Three mechanics matter over a twenty-year hold. The construction element of your basis must be depreciated 3 per cent for every year of ownership, floored at 20 per cent of initial cost, whatever the building’s condition. Where land and construction are not separated in the deed, land is deemed 20 per cent of cost, usually unfavourable in San Miguel, where land is a high share of value. And only capitalised improvements are deductible, never maintenance, and only with proper facturas: two decades of undocumented renovation is two decades of lost basis. The principal-residence exemption capped at 700,000 UDIs, MXN 6,166,187.30 at the UDI published for 10 July 2026, caps the exempt sale price rather than the gain, and belongs to Mexican tax residents. An owner holding from Europe is not one.

What San Miguel de Allende is not insulated from

Guanajuato carried a Level 3 designation, Reconsider Travel, in the US advisory reissued on 29 May 2026, alongside Jalisco the highest state rating among the Mexican markets we track. The primary source blocked every retrieval attempt and two secondary reports of the same advisory contradict each other, so treat that level as reported rather than confirmed.

February 2026 is not in doubt. Reprisals following a cartel leader’s death produced roughly 77 attacks in under 24 hours across about 23 Guanajuato municipalities, and San Miguel de Allende was among the places affected: an arson incident on 22 February, businesses and universities suspending activity, and a body showing signs of violence found in the municipality on 25 February. A brokerage account describing this as no unusual incidents and a single precautionary school closure did not survive fact-checking. Anyone telling you the city is structurally separate from its state is selling you something.

What we cannot tell you

• Any euro figure. No EUR/USD or EUR/MXN rate, and no consular residency threshold in euros. Madrid, like most consulates, was inaccessible.
• Measured appreciation. No repeat-sales index, hedonic index or public MLS series exists. Every appreciation percentage in circulation is modelled or asserted.
• A closed-sale price per square metre. Every available figure is an asking price or crowdsourced, and they disagree by roughly a factor of two.
• Days on market. The quoted 150-day average is an aggregator estimate whose own cited source contains no such figure.
• Buyer nationality mix. Nobody publishes one, so nobody knows how many Europeans buy here.
• The ratio of cadastral to market value, without which predial rates cannot be turned into a percentage of what you paid.
• Notary fees as actually quoted in 2026. The arancel is displaceable by agreement and no schedule of real fees is published.
• Whether consulates accept the property route to residency in practice, or which valuation they apply to the 91,710 UMA test.
