Rental arbitrage, from the owner's side
Rental arbitrage is the arrangement in which somebody who does not own a house takes it on a long lease, furnishes it, and re-lets it to guests by the night, keeping whatever separates the rent they pay from what the house takes in. The word is a market coinage and no Mexican statute uses it. The contract underneath it has a much older name — subarriendo, a sublease — and that is the name that decides what happens to the house, to the paperwork, and to the owner.
Owners of exceptional houses in Mexico almost never meet the term. They meet a proposal: a company offers a fixed monthly amount, several years, and the furnishing at its own expense, and the word arbitrage appears nowhere in it. The proposals arrive most often where there are many furnished apartments and a calendar that never fully closes, which in this country means Cancún before anywhere else. This guide is about recognising the model, and about what it does and does not move off the owner's side of the table.
What is rental arbitrage?
It is a sublease with a business model attached to it: an operator signs a long lease with the owner, pays a fixed rent every month whatever happens, and keeps whatever the house earns night by night. The owner's income stops moving with the season and becomes a rent; the operator's income becomes the distance between that rent and the nightly one.
Mexican law has a name for each half of that sentence. A lease exists when the two contracting parties bind each other reciprocally, one to grant the temporary use or enjoyment of a thing, and the other to pay a certain price for that use, and the same article caps a lease at ten years for buildings intended for habitation and twenty for those intended for commerce or industry. What the operator then does with the house is the second half: a sublease, which the Civil Code treats in a chapter of its own.
That chapter opens with the sentence the whole model depends on. A tenant may not sublease the leased thing in whole or in part, nor assign their rights, without the consent of the landlord; if they do, they are jointly liable with the subtenant for damages. An arbitrage arrangement is therefore not something an operator can arrive at on their own: it needs the owner's consent in the lease, which is why the request for it is the clearest signal in any proposal.
The form that consent takes changes who is left facing the owner. Where the sublease happens under a general authorisation written into the contract, the tenant remains liable to the landlord as if they themselves continued in the use or enjoyment of the thing; where the landlord expressly approves a specific sublease contract, the subtenant is subrogated into all the rights and obligations of the tenant, unless the parties agree otherwise. One of those two sentences will describe the situation, and which one it is has been decided before anyone has stayed a night.
Nothing in this is exotic to the tax side either, which surprises owners who expect a special regime. Income from granting the temporary use of real property includes what comes from leasing and from subleasing alike: the two sit in the same chapter of the income tax law, and the operator's revenue and the owner's rent are both inside it, each in the hands of whoever received it.
Who takes the risk in a rental arbitrage deal?
The operator takes the occupancy risk and the owner takes the counterparty risk, and the two are not the same shape. If the house does not fill, the operator still owes the rent and absorbs the difference; if the operator stops paying or walks away, the owner is left holding a house that has been open to strangers for months under a commercial arrangement they did not write.
The wear is the part that is easiest to underestimate, because the law places it one step away from the owner. A tenant is obliged to answer for the damage the leased thing suffers through their own fault or negligence, that of their family, their staff or their subtenants, and is separately obliged to use the thing only for the agreed use or the one its nature and destination imply. Both obligations run from the operator to the owner, which is exactly as far as they run: a guest who ruins a floor is the operator's problem to answer for, and the owner's problem to prove.
Meanwhile the obligations that come with being the landlord do not move at all. The owner remains bound, even without an express clause, to keep the leased thing in the same condition during the lease, making for that purpose all the necessary repairs. A roof that fails in the third year of an arbitrage lease is repaired by the person whose name is on the deed, in a house whose calendar somebody else controls.
The proposal itself usually opens by answering the question owners actually arrive with, which is how much they can rent their house for in Mexico. That figure is worth reading for what it is: an operator's estimate of their own revenue, presented in order to make the fixed rent underneath it look modest by comparison. This guide does not answer that question and no honest one does in the abstract, because the number depends on the house, the season, the building's own rules and a calendar nobody has run yet.
There is also a remedy on the owner's side, and it is worth knowing before rather than after. The landlord may demand rescission of the contract for the subleasing of the thing in contravention of article 2480, which is the article that requires consent. An owner who discovers a house on a nightly platform without having agreed to it is not without recourse; an owner who signed a general authorisation and later regrets it is in a different position entirely.
How does an owner recognise an arbitrage proposal when it arrives?
By the shape of the money rather than by the vocabulary, because the vocabulary is almost never there. An arbitrage proposal offers a fixed monthly amount and a term of years, and asks for the right to sublet or to list the property; a management proposal offers a share of what the house actually earns and asks for no such right.
Four other signals travel with it, and any two of them together settle the reading. The furnishing is offered at the operator's expense, which only makes sense to somebody who will keep the upside. The counterparty is a company rather than a person, and the lease is described as corporate. The term is longer than a family would ask for. And somewhere in the draft there is a clause permitting sublease, assignment, or the listing of the property on third-party platforms, written in general terms rather than for one named arrangement.
The proposal will usually come from a short-term rental company that operates a portfolio of units in the same city, and the portfolio is the point: the model needs several houses to average out the empty weeks. That is neither hidden nor sinister, and the questions it raises are practical ones about who is exposed to what. It is also different in kind from the arrangement described on the page about managed rentals, where nobody holds a lease and the house is never sublet.
The registrations are where the model becomes visible from outside, and in Quintana Roo the definition is explicit about it. A host is the person, natural or legal, who provides lodging services in properties of their ownership, possession or administration through a digital platform — possession is enough, so under an arbitrage lease the host is the operator and not the owner. Where lodging is provided through a host, that host must apply for registration in the State Taxpayers Registry and obtain the Certificate of State Tax Obligations for each of the establishments where the service is provided.
The federal side works the same way. Registration in the National Tourism Registry is obligatory for tourism service providers, who have thirty calendar days from the start of operations to register. In an arbitrage arrangement the provider is the operator, so an owner who wants to know whether the house is being run within the rules is asking about somebody else's registrations — which is a fair question to put in writing before signing, and an awkward one to ask afterwards.
What is the difference between arbitrage, co-hosting and full management?
The difference is who holds the house and out of what they are paid. In arbitrage the operator holds a lease and keeps the spread; in co-hosting they hold nothing and take a share of each booking; in full management they hold neither the lease nor the listing and are paid a percentage of what the house earns, net of costs.
The three words arrive in the same week and are used loosely, which is how an owner ends up comparing a rent against a percentage as though the two were the same kind of offer. They are not. A rent is a price for the house; a percentage is a price for work. Only the second one moves when the house does badly, and only the first one leaves somebody else deciding what the house is worth per night.
What is sold as Airbnb co-hosting services sits closest to the platform and furthest from the house: a co-host is added to a listing that stays in the owner's name, handles messages and turnovers, and takes their share of each booking. What is sold as Airbnb management services is usually broader — pricing, calendar, cleaning, guest communication — and can be either a percentage arrangement or, in some hands, an arbitrage lease with a friendlier name on the cover. The way to tell is the same in both cases: ask whose name is on the lodging registration and out of what the operator is paid, which is the same test set out in the guide to how property managers charge.
| Arrangement | Who holds the house | Who is paid, and out of what | What the owner sees |
|---|---|---|---|
| Rental arbitrage | The operator, under a lease of several years, with the right to sublet | The operator keeps the spread between the fixed rent and the nightly revenue | A fixed rent, and no view of the calendar, the rates or the guests |
| Co-hosting | Nobody: the listing and the house both stay with the owner | The co-host takes a share of each booking they handle | The bookings, on the owner's own account, minus the co-host's share |
| Full management | Nobody: the owner remains the party to every contract | A percentage of what the house earns, net of expenses | A monthly statement of gross income, deductions and net |
The bottom row is where an administration office sits, and the third column is the whole of the difference from the first: an office that is paid a percentage of what the house earns has no revenue when the house has none, which is a different set of incentives from an operator who has already committed to a rent. What that produces every month is described on the page about monthly owner reporting, and the work it covers is set out in the guide to what a property manager does.
What does an owner give up, and what do they keep?
They give up the calendar, the nightly rate and any sight of the guest, and they keep every obligation the law attaches to owning the house and to letting it. That asymmetry is the decision in one sentence, and it is decided at signature rather than discovered later.
The tax obligations are the clearest case, because they follow the money rather than the arrangement. A person who receives income from granting the temporary use of real property must apply for registration in the Federal Taxpayers Registry, keep accounting records, and issue fiscal receipts for the consideration received. A fixed rent from an operator is exactly that kind of income, so the owner's obligations do not shrink because the house is now somebody else's project. What each of them requires is set out on the page about obligations and compliance.
The ownership costs behave the same way. Property tax is due on the house rather than on its use, the condominium fee arrives on its own schedule, and the building's rules about nightly stays apply to the house whoever is operating it — a lease does not carry any of that across to the operator unless the contract says so in terms.
What is genuinely transferred is the work and the information, and the second one is the part owners tend to notice late. Under an arbitrage lease there is no monthly account of what the house did, because what the house did is the operator's business and not the owner's: the rent arrives, and the season, the rates, the length of stays and the state of the furniture are all on the other side of a wall. Two years of that is a long time to be told nothing about a building you are still repairing.
None of which makes the model wrong. For an apartment held as an investment, at a distance, with no personal use and no attachment to how it is kept, a fixed rent from a competent operator is a defensible arrangement and a simpler one to administer. For a house the owner uses, in a building with its own rules, the calculation is the one set out in the guide to whether property management is worth it, and it turns on exposure rather than on the size of the cheque.
What questions settle it before anything is signed?
Five, and all of them are about names on documents rather than about numbers. Numbers are what a proposal is designed to be read for; names are what decides who answers when something goes wrong.
Where does an administration office fit, and where does it not?
It does not sit on the operator's side of an arbitrage lease, and that is a matter of structure rather than of preference. An office that took the house on a lease would be trading on the spread, which is a different business with different incentives from being paid a percentage of what the house earns.
The arrangement it works under instead is set out on the page about full property administration, where the owner stays party to every contract and nothing is sublet. Where a proposal of this kind has already arrived, the useful thing to do with it is the unglamorous one: read what the house is being asked to give up, and say so plainly.
What it cannot do, and what no office should offer, is tell an owner whether to sign. Whether a particular draft is sound, what it does to a particular estate, and how it reads against a particular building's rules are questions for that owner's own lawyer and accountant, on that owner's own documents. The distinction is not a formality: an office that answers those questions is doing work it is not responsible for, on facts it does not have.
Is rental arbitrage legal in Mexico?
The term appears in no Mexican statute, but the arrangement it describes is a sublease, and the Federal Civil Code is explicit about it: a tenant may not sublease the leased property in whole or in part, nor assign their rights, without the landlord's consent, and if they do they are jointly liable with the subtenant for damages. So the question is not whether the model is permitted in general but whether this lease permits it, and in what terms. Whether a particular contract does, and what a particular building's rules add to it, is a question for the owner's own lawyer on the owner's own documents.
What is the difference between rental arbitrage and co-hosting?
In arbitrage the operator holds a long lease on the house, pays a fixed rent whatever the season does, and keeps the difference between that rent and what the house earns by the night. In co-hosting nobody holds a lease: the listing stays in the owner's name, the bookings are received on the owner's account, and the co-host takes a share of the ones they handle. The first is a transfer of the house for a term; the second is a service on top of an arrangement the owner still controls.
Does an owner still declare income under a rental arbitrage lease?
The rent an owner receives under such a lease is income from granting the temporary use of real property, which is the same chapter of the income tax law that covers leasing and subleasing alike, so it does not become somebody else's income because somebody else is running the house. The obligations attached to receiving it are the ordinary ones: registration, accounting records and fiscal receipts for the consideration received. How they apply to a specific owner, and what the operator's own filings look like, is for that owner's accountant to determine.
How much can I rent my house for in Mexico?
No figure given in the abstract is worth anything, and any proposal that leads with one is quoting its own expected revenue rather than the owner's. What the house can command depends on the building and its rules, the season and how long it lasts where the house is, the condition and the furnishing, and the costs that come off the top before anything is net. An operator's estimate is a sales document; the number that matters to an owner under an arbitrage lease is the fixed rent underneath it, which does not move for years.
