A short-let is the right answer for your first month in Mérida, Mexico and the wrong answer for your first year. The crossover is usually somewhere in month two or three, and it is not where the nightly rate suggests, because a short-let bundles in things a lease charges you for separately and a lease bundles in things a short-let never mentions.
So: book the short-let, deliberately, for as long as it takes you to find a place properly. Then stop. What follows is how to work out where your own crossover sits, using live numbers rather than the ones in this post, because there are none in this post — nightly rates in this city swing with the visitor season and a figure printed today would mislead you by December.
The two cost stacks, side by side
The mistake is comparing a nightly rate against a monthly rent. They are not the same kind of number. Write both stacks out in full and the comparison becomes obvious.
| Line | Short-let | Long-term lease |
|---|---|---|
| Base | Nightly rate × nights, after the host’s monthly discount | Monthly rent |
| Platform and cleaning fees | Yes, once per booking | No |
| Electricity | Almost always included | Yours, and in this city that is the large one |
| Water, gas, internet | Included | Yours |
| Furniture, kitchen kit, linens | Included | Yours, unless furnished — and “furnished” varies |
| Deposit | Small or none | One to two months, held |
| Guarantee | None | Fiador, póliza or months upfront |
| Agency commission | None | Sometimes, around a month |
| Exit | Leave any time | Notice period, forfeit clause |
Two lines in that table are where foreigners get the comparison wrong.
Electricity. A short-let quote includes it. A lease does not, and in Mérida that is not a rounding error: air conditioning can reach around 40% of a household’s warm-season consumption, which the Diario de Yucatán reported in April 2026, and the domestic tariff steps up with how much you use rather than charging flat. Comparing a summer short-let against a summer lease without adding an electricity estimate to the lease side gives you the wrong answer by a wide margin. What that line actually looks like is in the CFE summer bill.
Setup. Everything you have to buy once — a bed, a fridge if there is none, fans, kitchen equipment, a mattress you can sleep on — is a real cost of the lease side, and it is paid in your first fortnight when your money is already stretched. Amortise it over the length of the lease rather than pretending it is not there. The full version of that number is what month one costs before you have lived it.
The formula, and where your crossover actually is
Work it out once, on paper, with numbers you have read from live listings this week:
Short-let monthly total = (nightly rate × 30, after the monthly discount) + cleaning fee + platform fee.
Lease monthly total = rent + electricity estimate + water + gas + internet + (setup ÷ months you will stay) + (deposit and guarantee ÷ months you will stay, for the portion you will not get back).
Then read the two totals against each other at three different stay lengths: three months, six months, twelve. The lease side falls as the stay lengthens, because setup and guarantee spread out; the short-let side does not move. That is the whole mechanism, and it is why the answer depends entirely on how long you are actually staying — not on which is “cheaper”.
Three things that shift the crossover later, towards the short-let:
- You are still deciding on a colonia. A wrong lease in the wrong neighbourhood costs more than three months of short-let premium. Where to live is an arithmetic problem, and it takes weeks to answer honestly.
- You are here in the hottest months and the short-let includes electricity. In May, June and July that inclusion is worth more than it is in January.
- Your residency is not settled. If there is any chance you are leaving, a twelve-month commitment with a forfeit clause is a bet, not a saving.
And three that shift it earlier, towards the lease:
- You know the colonia, because you did a scouting trip or you have been here a month.
- You are arriving with a household — two people and a shipment make the setup cost proportionally smaller and the short-let premium larger.
- It is the visitor season. Short-let pricing in Mérida follows the dry winter months when visitors come; the same apartment is a different price in January and in August. Long-term rentals in Mérida move far less.
What the monthly discount does and does not do
Every major short-let platform lets a host set a monthly discount, applied automatically when a booking runs past a set number of nights. It is real, it is often substantial, and it is set by that host, not by the platform — so it is a number you read on the listing, not a rate you can assume.
Two things it does not do:
It does not make the booking a lease. You have no security of tenure, no notice period in your favour, and no address document. A short-let confirmation is not the proof of address a counter will accept, and the difference matters when you reach a bank or a phone contract.
It does not usually survive a re-booking. Book two consecutive months as two bookings and you often pay the fees twice and lose the discount tier. If you are extending, extend the existing booking rather than starting a new one, and ask the host directly — a host with an empty calendar in September will negotiate off-platform pricing that no filter will show you.
The move nobody plans for: short-let to lease in the same city
The transition is where a fortnight disappears if you have not sequenced it. In order:
- Overlap deliberately. Keep the short-let for a week past the lease start date. Moving between two places you hold is calm; moving out of one on the day you get keys to the other is not.
- Sign before you give notice. Obvious, and skipped by people who are certain the deal is done.
- Budget the double month. Deposit, first month, guarantee and the tail of the short-let land in the same fortnight. That is the peak of your cash requirement for the whole year, and it arrives when transfers from home are still slow because your Mexican account is new.
- Read the four clauses first. The guarantee, the increase, the deposit and the AC clause are what you are actually signing.
When the short-let is genuinely the right answer for a year
It sometimes is, and the site would be dishonest to pretend otherwise. If you are here on a visitor stamp rather than residency, if you genuinely do not know whether you are staying, if you cannot produce a guarantee and will not pay a póliza, or if you need a place that is furnished, serviced and requires nothing of you — then paying the premium buys optionality, and optionality is worth money when your situation is unresolved.
What it is not is cheaper. Price it honestly, decide, and stop re-deciding every month.
Checked on
Checked on 4 September 2026. No nightly rate, monthly rent or utility figure is quoted here on purpose: short-let pricing in this city is seasonal and long-term rents vary by colonia, so a printed number would be wrong within weeks. Read live figures from the listing portals and the platforms themselves, fill in the two stacks above, and the answer is yours rather than a stranger’s. The air-conditioning share of warm-season household consumption is the Diario de Yucatán’s reporting from April 2026.
