How the fee splits between listing and selling side

No source publishes the co-brokerage split for this market, and AMPI publishes no membership or coverage disclosure.

The customary real estate agency commission in San Miguel de Allende is 6 per cent of the sale price plus 16 per cent IVA. That is an effective 6.96 per cent, paid by the seller out of proceeds at closing.

On a MXN 10,000,000 sale, roughly US$573,000 at the ECB reference rate of 17.4601 on 23 July 2026, that is MXN 696,000. It is the single largest cost line in the transaction, larger than the acquisition tax, larger than the notary, larger than everything the state and the municipality charge put together.

You will not find it stated on the website of any brokerage that operates here, with one partial exception. That is the subject of this page. We publish the figure because we earn no part of it, and because a market whose largest cost is the one item nobody prints is a market where buyers decide with a hole in the middle of the arithmetic.

This is a description of an incentive structure, not an allegation against anybody. Most agents in San Miguel are competent and many are scrupulous, and the structural point stands whether or not that is true of the individual you are sitting across from.

What the rate is, and how thin the evidence is

Here is every published statement of a San Miguel commission rate we could locate.

That is the whole public record. One brokerage, saying the same thing three times, twice without a date and once only in Spanish, plus one aggregator giving a wider range without a stated method.

We hold the figure at low confidence and say so. It is a single interested source describing its own industry’s pricing. There is no association tariff to check it against, no regulator collecting it, and no transaction record from which an average could be computed. What can be said is that 6 per cent plus IVA is the number the local industry uses when it describes itself, and that nothing contradicts it.

The second row is the more telling one. A brokerage article about what a buyer pays at closing states the seller’s 6 per cent commission in passing, and has not been updated since November 2023. The number is not exactly suppressed. It is simply never placed where a buyer looking for it would find it.

Why the figure is hard to find

A survey of search results for the head terms in this market on 23 July 2026 returned seven of seven page-one domains that were commission-earning brokerages or franchise listing sites. Zero independent publishers, zero government sources, zero statistical bodies. Exact rank positions from that survey are not verified; the composition of the result set is the reliable part, and the composition is total.

Every one of those firms is answering the question with the answer in its own pocket. No conspiracy is required for this outcome and no bad faith needs to be assumed. A firm writes about what helps it win listings and buyers, its own fee helps it do neither, so the fee does not get written about. Multiply that across every publisher on the page and the result is a market where the largest transaction cost has no public documentation.

We could locate no Mexican federal statute, no Guanajuato state law, no municipal rule and no published association standard requiring that the commission be disclosed to the buyer. We cannot prove none exists. We can say that we searched and found none, and that no page we examined discloses the fee to buyers as a matter of course.

What it costs against everything else

The comparison that matters is not the percentage. It is the percentage against the other percentages.

The commission is larger than every other line in that table added together. Two caveats keep that comparison honest. The notary figure is the maximum under a residual scale that applies only where there is no agreement between notary and client, and real quoted fees run above it by an amount nobody publishes. Escrow, appraisal, translation and gestoría charges sit outside the table because no statute fixes them.

Even allowing generously for both, the shape holds across price points, because the commission is a flat percentage while ISAI is progressive and the government fees are flat pesos.

In dollars, applied to the only closed-sale price figures anyone publishes: the 2025 average resale sale price of $568,829 carries a commission of $34,130, or $39,590 with IVA. On the 2024 average of $650,462 it is $39,028, or $45,272 with IVA. Both averages come from one brokerage’s own view of the local MLS and inherit that source’s limits; the arithmetic applied to them is deterministic.

Note what happens to the published closing-cost ranges once this line is added. San Miguel buyer closing costs are variously given as 4 to 9 per cent, up to about 6 per cent, roughly 5 per cent, and 5 to 6 per cent against about 8 per cent in Querétaro. Not one of those ranges includes agency commission, because commission is not a buyer cost by custom. The round trip is what a buyer should model, and on the round trip the commission arrives at the exit, on the sale price rather than the purchase price.

Who actually bears it

The seller writes the cheque. That much is settled by custom and is not in dispute.

Who bears the cost economically is genuinely open, and the confident answer given in both directions is wrong. The lazy line is that buyers always fund the commission because sellers price it in. That is true only where sellers have pricing power. Where they do not, the fee comes out of proceeds and the seller bears it.

San Miguel in July 2026 is not a seller’s market. Months of inventory averaged 29.6 over January to May 2026, against 17.6 in the same period of 2025, and against the 15 to 18 months the same source calls normal here. Active listings rose 45 per cent year on year to 860 in May. The 2025 average sale price fell 12.6 per cent, and sales above $2 million fell from 19 to 12.

Under those conditions a seller who adds 6.96 per cent to the asking price mostly succeeds in adding months to the marketing period. The honest statement is conditional, not absolute: incidence moves with bargaining power, and bargaining power currently sits with buyers. Nobody has measured the split, here or in any other Mexican market, and no published sale-to-list series exists from which it could be inferred.

How it splits, which nobody publishes

No source publishes how the 6 per cent divides between the listing side and the selling side in San Miguel de Allende. Not the brokerages, not AMPI, not the MLS. The only adjacent published figure is TheLatinvestor’s note that a buyer-side agreement, where one is separately negotiated, runs 0 to 2 per cent paid by the buyer, which implies buyer-side representation is an add-on rather than the norm.

That gap sits on top of a second one. Market updates from a local brokerage describe AMPI San Miguel as navigating an MLS system transition and state that not all agencies participate in the same MLS. Where the co-brokerage infrastructure is itself partial, the answer to how the fee is shared may not be uniform across firms. We record the question as unresolved rather than estimating it.

The consequence for a buyer is narrow but real. If an agent shows you a property, nothing published tells you whether that agent will be paid from one side of the deal or both, and no disclosure convention would surface it. Asking is the only available remedy.

Is it negotiable

Nothing fixes it. We searched for a statute, a state law, a municipal rule and a published association tariff governing real estate commission in Guanajuato, and found none of them.

That absence is more striking when set against notary fees, which do have a statutory scale. Guanajuato’s Ley Arancelaria sets a residual notary tariff, and Article 2 of that law states plainly that the scale applies only where there is no agreement between the notary and the client. Even the regulated profession’s schedule is a default rather than a ceiling. For real estate commission there is not even a default.

So the commission is a contract term, negotiated between seller and brokerage in a listing agreement signed before any buyer is identified. Buyers do not negotiate it because buyers are not party to it. Sellers can, and at 29.6 months of inventory the leverage a seller holds when signing a listing is unusually good.

A lower commission may buy less effort, and that trade-off is unmeasurable, because no San Miguel data on marketing outcomes by commission level exists. What a seller should not accept is the framing that the rate is standard in any sense stronger than customary.

IVA, and what the fee is worth at resale

Two provisions of Mexican tax law govern the commission, and neither appears on any local brokerage page we examined.

The first is IVA. Article 9 of the Ley del Impuesto al Valor Agregado exempts the sale of land and the sale of a building used as a dwelling, so no IVA falls on the price of an ordinary San Miguel home. IVA at the standard 16 per cent does fall on the services around the deal: agency commission, notary fees, legal and appraisal work. That is where 6 per cent becomes 6.96 per cent, and why a quoted rate is ambiguous until you ask which side of IVA it sits on.

The second is deductibility. Article 121 fracción IV of the Ley del Impuesto sobre la Renta allows commissions and brokerage paid by the seller, whether incurred on the acquisition or on the sale, as a deduction against the gain, indexed from the month of the outlay to the month before the sale. Read plainly, a buyer-side fee paid on the way in is deductible on the way out.

Two conditions constrain that. A non-resident taxed under the Article 160 default of 25 per cent of gross proceeds receives no deductions at all, so the commission is worth nothing. It becomes available only under the alternative election of 35 per cent on the computed gain, which Article 160 permits without a Mexican representative where the sale is by public deed. And the notario calculates and remits the tax under their own responsibility, which is why deductions unsupported by a proper factura tend not to survive. Keep the invoice.

What the structure does to the advice

Here is the arithmetic, and it does not depend on knowing the split.

The commission is a fixed percentage of the price. If a buyer negotiates 5 per cent off, the fee falls by 5 per cent. If the transaction does not happen, the fee falls by 100 per cent. On that comparison the incentive to make a deal happen is twenty times the incentive to make it happen at a high price, and the ratio holds whatever the rate and whatever the split.

It points somewhere more useful than the usual suspicion. The pressure in this structure is not toward overpaying. An agent who talks a buyer into $30,000 more on a $600,000 house adds at most $1,800 to the whole commission pool before IVA, of which they take a share, and risks the deal. The pressure is toward transacting at all.

Which means three pieces of advice are never compensated. Wait. Rent for six months first. This house is overpriced and you should walk. Each is correct in some fraction of cases, and each pays nothing to the person best placed to give it. A structure that never pays for a category of advice produces less of it than the market needs. That is not a claim about anyone’s integrity. It is a claim about what unpaid work gets done.

The listing side mirrors it. At 29.6 months of inventory, the most valuable service a listing agent can perform is to tell a seller the asking price is too high. That conversation shrinks the agent’s own fee and risks losing the listing to a competitor willing to quote a more flattering number. Nothing in the structure rewards it.

None of this is peculiar to San Miguel. Percentage commission on a contingent close does the same thing everywhere. It matters more here because the counterweights that exist elsewhere, published sold prices, days-on-market series, a public registry, an independent valuation industry, are all absent. A buyer here is relying on an agent’s judgement in a market where almost no figure is independently checkable.

Who is your advocate, and who is not

The notario is not. Under the Ley del Notariado para el Estado de Guanajuato the notario is a professional of law invested with public faith, exercising a public function under the state Executive, governed by principles that include impartiality and legality. That is a genuine protection, worth more than most buyers realise: the notario verifies title, computes and remits the seller’s tax under their own responsibility, and will not close over an unresolved defect. But an impartial public officer is by definition not your advocate. The comparison a North American buyer instinctively reaches for, the closing attorney or the title company, is the wrong one.

The listing agent is not either. That agent is engaged by the seller. The agent who shows you the house may or may not be, and nothing published will tell you. Where the same agent or brokerage stands on both sides, no party in the room is separately retained to protect the buyer’s position on price, on condition, or on what belongs in the offer.

The remedy is unexciting and it works: retain an independent Mexican abogado, unconnected to the brokerage, and pay them yourself. On a purchase in the hundreds of thousands of dollars that is a small line against a commission of 6.96 per cent already being paid to somebody, just not to anybody working for you.

AMPI: what membership does and does not establish

AMPI, the Asociación Mexicana de Profesionales Inmobiliarios, is the trade association most often cited as a credential in this market. It is worth being precise about what that credential is evidence of.

We checked the AMPI San Miguel de Allende site directly on 23 July 2026. It publishes property listings and an agent directory. It publishes no market statistics of any kind: no closing counts, no prices, no inventory, no days on market. We also found no published membership standard, no code of conduct, no disciplinary procedure and no statement of what proportion of local transactions its members handle. A separate brokerage source describes the chapter as navigating an MLS system transition with agencies not all on the same system.

So membership establishes that a firm has joined an association. It is not a state licence, and we found no Guanajuato licensing regime for real estate practice to compare it to. It carries no published fee schedule, so it says nothing about what a member charges, and with no coverage figures it cannot tell a buyer how much of the market the directory represents.

That is not an argument against dealing with AMPI members. It is an argument against treating the badge as a substitute for the questions below.

What we could not establish

Recorded here rather than estimated, because estimating them is what the rest of this market does.

• The actual distribution of commission rates charged in San Miguel. One customary figure exists; no survey, register or transaction dataset does.
• The split between listing and selling side, and whether it is uniform across firms operating on different MLS systems.
• How often one agent or brokerage represents both sides of a San Miguel transaction.
• Whether any Guanajuato statute or state register governs real estate practice, and what duties, if any, an agent owes a buyer.
• AMPI membership requirements, disciplinary history and market coverage.
• The economic incidence of the commission, meaning how much of it is genuinely borne by sellers and how much by buyers through price.
• Whether commission rates have moved at all in response to inventory doubling since 2025.

Any of these from a body without a commission motive would improve this page. None of them exists.

Questions worth asking, and why

None of these is a hostile question. A firm that answers them plainly has told you something useful about how it works, and most will.

Why this page exists

Every website that ranks for this question in San Miguel de Allende is paid out of the fee being asked about. We are not. We sell no listings, represent no buyer and no seller, take no referral fee from any brokerage, notario or lawyer, and earn nothing whether or not you transact. That is the only reason this page can state the number in its first line.

The commission is not the problem. Six per cent plus IVA may well be a fair price for competent work in a thin, cash-driven, largely foreign market with no public data, where an agent’s local knowledge is genuinely load-bearing. The problem is a market in which the largest single cost of the transaction is the one item no participant will print, so a buyer cannot weigh what they are paying against what they are getting.

State the fee, and that judgement becomes possible.

This is published research, not legal or tax advice. Your notario is the legal authority on your transaction, and questions about the deductibility of commission, capital gains treatment and IVA should be put to your notario and a Mexican tax adviser before you sign. We have no financial interest in whether your transaction closes.
